All You Need To Know About The Emerging Star Of Optical Chip

As the demand for higher speed and bandwidth increases, optical modules, which are essential for optical-electrical conversion, have experienced explosive growth. Consequently, optical chips, a crucial component of these modules, have also come into the spotlight.

What is an Optical Chip？

An optical chip, also known as a photonic chip, is an integrated circuit that uses light waves for information transmission and data processing. Typically made from compound semiconductor materials such as InP and GaAs, it achieves optical-electrical signal conversion through the generation and absorption of photons during internal energy level transitions.

These chips rely on dielectric waveguides in integrated optics or silicon photonics to transmit guided light signals. They integrate the modulation, transmission, and demodulation of optical and electrical signals on a single substrate or chip. Compared to traditional electronic chips, photonic chips use light instead of electrical currents to transmit data. This results in high density, high speed, and low power consumption.

In short, optical chips are fundamental components for converting optical signals to electrical signals. Their performance determines the transmission efficiency of optical communication systems.

Development Status of Optical Chip

The development of optical chips dates back to 1969 when Bell Labs in the United States proposed the concept of integrated optics. However, due to technological and commercial challenges, significant progress didn’t occur until the early 21st century. At that time, companies like Intel and IBM, along with academic institutions, began focusing on silicon chip optical signal transmission technology. Their aim was to replace data circuits between chips with optical pathways.

Today, pure photonic devices can function as independent modules. However, they still face limitations. Controlling optical switches is challenging, and these devices can’t act as storage units like electronic devices. As a result, pure photonic devices cannot fully handle information processing on their own and still need electronic devices. Therefore, a purely “photonic chip” is still a concept and not yet a practical system. The current “photonic chips” are actually optoelectronic hybrid chips that integrate photonic devices or functions. They still struggle with integrating high-density light sources and low-loss, high-speed electro-optic modulators.

Despite being in the early stages, photonic integrated circuits are set to become the mainstream in optical device development. The future of photonic chips will involve integration with mature electronic chip technology. Using advanced manufacturing processes and modular techniques from electronic chips, silicon photonics, which combines the strengths of both photonics and electronics, will lead the way forward.

From a market perspective, the United States was the first country to start and excel in the field of silicon photonics. Early on, associations were established to guide capital and various forces into the optoelectronics field. Singapore’s IME is also one of the early platforms for silicon photonics processes, contributing significantly to the industry’s development.

Currently, the global optical chip industry chain has gradually matured, with representative companies involved in every stage from basic research to manufacturing processes and commercial applications. Companies like Intel, Cisco, and NVIDIA dominate the shipment volumes of silicon optical chips and modules, becoming leaders in the industry.

The larger the data flow, the more complex the data processing methods, making data centers increasingly important. Currently, the global solution to handling data flow is the construction of large-scale data centers. Therefore, the global construction of these large-scale data centers will be a significant driving force for the optical module market, thereby driving the demand for optical chips.

Telecommunications

Currently, countries around the world are striving to meet the demands of 5G networks. Compared to 4G, 5G uses higher frequencies, which significantly weakens its coverage capability. As a result, the number of base stations required to cover the same area with 5G will undoubtedly exceed that of 4G. The communication services in the 5G era have also created a huge demand for optical chips and optical modules.

Future Trends in Optical Chip

As the internet industry develops, the demand for optical modules is gradually trending towards miniaturization and high performance. The future technological direction of optical chips can be embodied in silicon photonics technology.

Silicon photonics technology is a new generation of technology that develops and integrates optical devices on silicon and silicon-based substrates using CMOS processes. Its core concept is to use laser beams instead of electronic signals for data transmission.

A Comprehensive Guide to Optical Module Form Factors

As the demand for high-performance computing grows, optical modules are evolving to meet these needs. But why choose different optical modules, and how do they function in various situations? This article will delve into the different form factors to help you understand optical modules and explore their close correlation with the number of SerDes channels.

Progression from Fundamental SFP to Advanced OSFP

Optical module consists of optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include the transmitter and receiver parts, whose role is to convert the electrical signals into optical signals at the transmitter side, and then convert the optical signals into electrical signals at the receiver side after being transmitted through optical fibers. The form factor of an optical module determines its size and is the primary way to differentiate between optical modules. According to their evolution, optical modules can be mainly divided into nine types, which we will introduce in the following paragraphs.

The Foundation: Small Form-factor Pluggable (SFP)

SFP, or Small Form-factor Pluggable, is a compact, lightweight version of the GBIC module, designed to support gigabit rates. As the successor to GBIC, SFP has become the foundational form factor for modern optical modules.

One of the most significant advantages of SFP over GBIC is its reduced size. The SFP module is half the size of a GBIC module, allowing for more than double the number of ports to be configured on the same panel. This space efficiency is crucial for high-density networking environments.

SFP modules support a maximum bandwidth of up to 4Gbps and are typically equipped with a single gigabit SerDes (Serializer/Deserializer) channel. This capability makes SFP a versatile and widely used option for various networking applications.

Transition to Higher Speeds: SFP+ and SFP28

SFP+, as we can infer from its abbreviation, is a plus version of the SFP module. Its official name is Enhanced Small Form-factor Pluggable. SFP+ is specifically designed for 10Gbps Ethernet, featuring several technical advancements and compatibility with higher speed standards.

Unlike SFP, which typically supports up to 4Gbps, SFP+ can handle data rates up to 10Gbps, making it a crucial component in modern high-speed networking environments. In addition to the significant increase in data transmission rates, SFP+ retains the compact size and hot-swappable functionality of SFP, allowing for seamless upgrades and maintenance without network downtime. SFP+ modules typically support a single 10Gbps SerDes channel, further enhancing their suitability for high-performance computing and data center applications.

SFP28, short for Small Form-factor Pluggable 28, is an advanced version of the SFP+ module. Although it shares the same size as SFP+, SFP28 supports optical modules with a data rate of 25Gbps. Specifically designed for 25Gbps Ethernet, SFP28 is equipped with a single 28G SerDes channel. SFP28 is essential in modern high-speed networks due to its ability to handle higher data rates while maintaining the compact size and form factor of its predecessors. This compatibility with existing SFP+ slots allows for easy upgrades and integration into current network infrastructures without the need for significant hardware changes.

The introduction of SFP28 addresses the increasing demand for higher bandwidth in data centers, enterprise networks, and other HPC environments. By providing a cost-effective and scalable solution for 25Gbps Ethernet, SFP28 plays a crucial role in the evolution of network technology, ensuring that networks can meet the growing data transmission requirements of today and tomorrow.

Quad Channel Modules: QSFP+ and QSFP28

QSFP+ and QSFP28 are both quad-channel SFP interfaces. Compared to SFP+ optical modules, they are larger in size. The difference between them is that QSFP+ supports 40G, while QSFP28 supports 100G. Specifically, QSFP+ introduces four independent SerDes channels, each supporting 10Gbps, resulting in a total rate of 40Gbps. On the other hand, QSFP28 continues the quad-channel design but increases the rate of each channel to 25Gbps, thereby boosting the total rate to 100Gbps.

Further Enhancements: QSFP56 and QSFP112

QSFP56 and QSFP112 represent advancements in technology with each channel supporting 50Gbps and 100Gbps respectively. QSFP56 offers a total data rate of 200Gbps, while QSFP112 reaches 400Gbps. Both of these modules rely on the same four-channel SerDes technology. However, the significant difference lies in the increased per-channel data rates, allowing for higher overall bandwidth without changing the number of channels. This evolution highlights the ongoing enhancements in optical modules to meet the growing demands for higher data transmission rates in modern high-speed networks.

Exploring Future with QSFP-DD and OSFP

QSFP-DD, or Quad Small Form Factor Pluggable-Double Density, indicates its “Double Density” nature right from its name. This advanced module supports data rates of 200G, 400G, and even up to 800G. With double density achieved through eight channels, QSFP-DD is designed for 400Gbps and beyond. These improvements make it a versatile choice for high-speed networking needs, offering design enhancements that cater to increased bandwidth requirements and various use cases.

On the other hand, OSFP, which stands for Octal Small Form-factor Pluggable, features an octal design, representing eight channels. Slightly larger than QSFP-DD, OSFP modules support 400G, 800G, and up to 1600G data rates. This design not only accommodates higher speeds but also includes considerations for effective thermal management and signal integrity, making OSFP a forward-looking solution for the next generation of high-performance networks.

FS provides newly module catagory of 800G QSFP-DD/OSFP, which paves the way for advancements in optical module technology, addressing the ever-growing demand for higher data rates and efficient performance in modern data centers and network infrastructures.

The Role of SerDes Technology

SerDes, short for Serializer Deserializer, is an electronic circuit commonly used in high-speed communication applications. It converts parallel data into serial data for transmission and then back into parallel data at the receiving end.

From the above introduction, it is evident that the speed and number of SerDes channels are directly related to the speed of optical modules. Simply put, increasing the number of channels or enhancing the speed of individual channels are the two main strategies to boost the total transmission rate of optical modules.

As technology advances, optical modules have evolved from single-channel to multi-channel designs, and SerDes speeds have progressed from 10Gbps to 112Gbps and beyond. Consequently, optical module speeds have upgraded from 1G, 10G, 25G, 40G, 100G, 200G, 400G, to 800G.

The development of SerDes technology not only determines the data transmission rate of networks but also affects the size, power consumption, and cost of optical modules.

Summary

In summary, the evolution of optical module form factors shows trends toward smaller sizes, higher speeds, lower costs, reduced power consumption, long-distance transmission, and hot-swappable capabilities. Increasing the number of channels or the speed of individual channels are the main strategies for boosting optical module speeds. In today’s rapidly advancing information age, the future of optical modules is promising, with ongoing innovations expected to empower high-performance computing and drive further technological progress.

Exploring the Path of Optical Module Technology

In the rapidly evolving field of optical module communication, some urgent demands have surfaced due to the exponential growth of data traffic and the ever-increasing need for faster and more reliable internet services. Optical modules are crucial components in data transmission, converting electrical signals into optical signals for transmission over fiber optic cables. As the backbone of modern communication networks, they play a vital role in data centers, telecommunications, and various high-speed internet services. In this article, we will focus on the latest advancements in optical module technology that address key challenges in current networks.

Why Upgrading Optical Module Technology is Necessary？

Demand for Higher Bandwidth: The rapid growth of data centers has created a strong demand for optical modules with higher bandwidth, lower power consumption, and smaller sizes. Current optical modules can face bandwidth bottlenecks when transmitting large amounts of data, making it difficult to meet the increasing business demands.
Signal Transmission Quality: Long-distance transmissions are often plagued by signal attenuation and distortion, affecting the stability and reliability of communications. High manufacturing and maintenance costs of traditional optical modules also pose a considerable barrier, limiting their broader application.
Cost Concerns: Cost is also a significant pain point. The manufacturing and maintenance costs of traditional optical modules are high, limiting their wider application.

To address these issues, several advanced technologies have emerged.

Silicon Photonics Technology

Silicon photonics technology uses silicon to integrate optical components with electronic circuits, creating compact, cost-effective, and high-performance optical devices. This technology is particularly important for High-Performance Computing (HPC), which processes vast amounts of data and performs complex computations. HPC systems rely on parallel computing and efficient algorithms to enhance performance. Silicon photonics provides faster and more efficient optical interconnects within these systems, improving data transmission speeds and reducing latency. By integrating silicon photonics, HPC systems can handle larger datasets and execute more complex calculations with greater efficiency.

Coherent Technology

Coherent technology is an advanced optical communication method that leverages the phase information of light to transmit data. Unlike traditional intensity modulation methods, coherent technology utilizes both the amplitude and phase of light for modulation, significantly enhancing data transmission rates and efficiency. This technology relies on complex signal processing algorithms and high-precision optical components to achieve superior spectral efficiency and noise resistance. Coherent technology addresses challenges of larger datasets by mitigating signal attenuation and distortion, ensuring consistent signal quality and stability.

In the realm of coherent technology, Digital Coherent Optics (DCO) and Analog Coherent Optics (ACO) represent two distinct approaches to implementing coherent optical communication. Next, we’ll help you get in touch with DCO and ACO as well as related high speed coherent modules.

DCO

DCO is a coherent optical communication technology where a Digital Signal Processor (DSP) is directly integrated into the optical module to enable digital processing of optical signals. FS offers OSFP 800G SR8 features a built-in Broadcom 7nm DSP chip, which provides excellent performance and flexibility. With real-time signal monitoring and adjustment via DSP, DCO systems can dynamically detect and correct changes and interferences in light waves, enhancing system stability and reliability.

Integration Approach for DCO Modules

DCO modules communicate digitally with host systems, reducing module size and facilitating compatibility across various networking equipment. For example, the DCO 400G DWDM module provides 400Gb/s of optical bandwidth over a single optical wavelength using coherent Dual Polarization 16QAM modulation. It is intended to be used with a host platform to support 400G transmission over optical links.

ACO

ACO, on the other hand, employs analog signal processing techniques for coherent modulation and demodulation. ACO modules typically communicate with host systems using analog signals. In long-distance optical communication, the high spectral efficiency of ACO allows it to transmit more data, thus meeting the requirements of long-distance communication.

Integration Approach for ACO Modules

Differences between DCO and ACO

Integration Method: DCO coherent modules directly integrate the DSP chip into the optical device, enabling digital communication between the module and the host system. This integration method facilitates communication among heterogeneous switch/router vendors and reduces the size of the module. Unlike DCO, ACO modules opt for analog communication between the module and the host system. This means that in ACO, analog signals are used for communication between the module and the host system.
Signal Processing: DCO utilizes DSP for coherent modulation and demodulation. This allows it to encode digital signals into light waves and enables real-time signal monitoring and adjustment, enhancing system stability and reliability. In contrast, ACO modules employ analog techniques, naturally interacting with continuous signals and aligning better with the properties of light waves.

In conclusion, DCO and ACO technologies use different integration and signal processing methods in coherent modules, making them suitable for various communication environments and applications. Based on digital signal processing, DCO emphasizes flexibility and dynamic adjustment in the digital domain. While ACO employs analog signal processing, interacting more naturally with continuous signals, making it suitable for specific scenarios requiring analog communication.

LPO

LPO (Linear drive pluggable optics) refers to optical modules that utilize linear direct drive technology, eliminating traditional DSP and CDR chips. In these optical modules, only high-linearity Driver and TIA components are retained, with integrated CTLE (Continuous Time Linear Equalization) and EQ (Equalization) functionalities. This approach achieves advantages in reducing power consumption and latency within systems. It discards the traditional DSP or CDR, achieving superior power consumption and cost control while significantly reducing latency, bringing revolutionary changes to the field of optical communications.

LRO

The Linear Receive Optics, also known as “HALO” (Half-retimed Linear Optics), architecture has been optimized. In LRO transceivers or Active Optical Cables (AOCs), a DSP is placed only on the transmission path from electrical input to optical output for signal retiming and equalization, while the receiver side is designed linearly.

This approach significantly reduces overall power consumption while maintaining interoperability and standards compliance. Overall, LRO is defined as a transitional technology between DSP and LPO optical modules.

CPO

CPO (Co-Packaged Optics) refers to the co-packaging of switch ASIC chips and silicon photonics engines on the same high-speed motherboard, thereby reducing signal attenuation, lowering system power consumption, reducing costs, and achieving high integration. For information, please check this article.

Summary

Thanks to the above technologies, optic modules achieve higher bandwidth, lower power consumption, and cost efficiency. SiP technology boosts optical module performance and lowers costs through high integration and affordability. Coherent technology ensures reliable, high-speed transmission over long distances. LPO modules reduce power consumption and costs, while LRO enhances signal stability. CPO tightly integrates optics and electronics, enhancing overall performance. Looking ahead, innovations in these technologies are poised to revolutionize HPC networking, supporting ever-increasing data needs and paving the way for future advancements in computing and communication.

Optimizing Data Centers with Large Layer 2 Network

In modern data center, large Layer 2 network play a crucial role in supporting high-performance and reliable networking for critical business applications. They simplify network management and enable adoption of new technologies, making them essential to data center architecture. This article will explore the necessity of a large Layer 2 network and the technologies used to implement them.

Why Is a Large Layer 2 Network Needed?

Traditional data center architecture typically follows a combination of Layer 2 (L2) and Layer 3 (L3) network designs, restricting the movement of servers across different Layer 2 domains. However, as data centers evolve from traditional setups to virtualized and cloud-based environments, the emergence of server virtualization technology demands the capability for dynamic VM migration. This process involves migrating a virtual machine from one physical server to another, ensuring it remains operational and unnoticed by end users. It enables administrators to flexibly allocate server resources or perform maintenance and upgrades on physical servers without disrupting users.

The key to dynamic VM migration is ensuring that services on the VM are uninterrupted during the transfer, which requires the VM’s IP address and operational state to remain unchanged. Therefore, dynamic VM migration can only occur within the same Layer 2 domain and not across different Layer 2 domains.

To achieve extensive or even cross-regional dynamic VM migration, all servers potentially involved in the migration must be included in the same Layer 2 domain, forming a larger Layer 2 network. This larger network allows for seamless, unrestricted VM migration across a wide area, known as a large Layer 2 network.

How to Achieve a Truly Large Layer 2 Network?

The technologies for implementing large Layer 2 network can be divided into two main categories based on their source. One category is proposed by network equipment manufacturers, including network device virtualization and routing optimized Layer 2 forwarding technologies. The other category is proposed by IT manufacturers, including overlay technology and EVN technology.

Network Device Virtualization

Network device virtualization technology combines two or more physical network devices that are redundant with each other and virtualizes them into a logical network device, which is presented as only one node in the entire network. By combining network device virtualization with link aggregation technology, the original multi-node, multi-link structure can be transformed into a logical single-node, single-link structure. This eliminates the possibility of loops and removes the need for deploying loop prevention protocols. Consequently, the scale of the Layer 2 network is no longer constrained by these protocols, thereby achieving a large Layer 2 network.

Building a large Layer 2 network using network virtualization technology results in a logically simple network that is easy to manage and maintain. However, compared to other technologies, the network scale is relatively small. In addition, these technologies are the private technologies of each vendor, and can only use devices from the same vendor for networking, which is usually suitable for building large Layer 2 networks at the level of small and medium-sized PODs.

Routing Optimized Layer 2 Forwarding Technology

The core issue with traditional Layer 2 network is the loop problem. To address this, manufacturers insert additional headers in front of Layer 2 packets and use routing calculations to control data forwarding across the entire network. This approach extends the Layer 2 network’s scale to cover the entire network without being limited by the number of core switches, thereby achieving a large Layer 2 network.

The forwarding of Layer 2 messages by means of route computation requires the definition of new protocol mechanisms. These new protocols include TRILL, FabricPath, SPB, etc. Taking TRILL as an example, it transparently transmits the original Ethernet frame by encapsulating it with a TRILL header and a new outer Ethernet frame. TRILL switches forward packets using the Nickname in the TRILL header, which can be collected, synchronized, and updated through the IS-IS routing protocol. When VMs migrate within a TRILL network, IS-IS can automatically update the forwarding tables on each switch, maintaining the VM’s IP address and state, thus enabling dynamic migration.

TRILL enables the creation of larger Layer 2 network and, being an IETF standard protocol, simplifies vendor interoperability. This makes it ideal for large PODs or entire data centers. However, TRILL deployment often necessitates new hardware and software, which can result in higher investment costs.

Overlay Technology

Overlay technology involves encapsulating the original Layer 2 packets sent by the source host, transmitting them transparently through the existing network, and then decapsulating them at the destination to retrieve the original packets, which are then forwarded to the target host. This process achieves Layer 2 communication between hosts. By encapsulating and decapsulating packets, an additional large Layer 2 network is effectively overlaid on top of the existing physical network, so it is called overlay technology.

This is equivalent to virtualizing the entire bearer network into a huge Layer 2 switch. Each virtual machine is directly connected to a port of this switch, so naturally there is no loop. The dynamic migration of a virtual machine is equivalent to changing the virtual machine from one port of the switch to another port, and the status can remain unchanged.

The overlay solution is proposed by IT vendors, such as VXLAN and NVGRE. In order to bulid an overlay network, FS has launched a VXLAN network solution, which uses VXLAN technology to fully improve network utilization and scalability. In the overlay solution, the bearer network only needs to meet the basic switching and forwarding capabilities, and the encapsulation and decapsulation of the original packets can be carried out by the virtual switches in the server, without relying on network devices.

EVN Technology

EVN (Easy Virtual Network) technology is designed for Layer 2 interconnection across data centers rather than within a single data center. Traditional methods like VPLS or enhanced VPLS over GRE often suffer from complex configurations, low bandwidth utilization, high deployment costs, and significant resource consumption. However, EVN, based on VXLAN tunnels, effectively addresses these issues and can be seen as an extension of VXLAN.

EVN technology uses the MP-BGP protocol to exchange MAC address information between Layer 2 networks and generates MAC address table entries for packet forwarding. It supports automatic VXLAN tunnel creation, multi-homing load balancing, BGP route reflection, and ARP caching. These features effectively address the issues found in VPLS and other Layer 2 interconnection technologies, making EVN an ideal solution for data center Layer 2 interconnection.

Summary

In this article, we discussed the importance of a large Layer 2 network in modern data centers, emphasizing its role in supporting virtualization, dynamic VM migrations, and the technologies needed for scalability. As an ICT company, FS is committed to being the top provider for businesses seeking dependable, cost-effective solutions for their network architecture. Utilizing our company’s advanced switches can significantly enhance the scalability of data centers, ensuring robust support for large Layer 2 networks.

Commonly Used Fault Detection Technologies

In the next section, we will explore some common fault detection technologies essential for maintaining the robustness of networks, particularly within the dynamic environment of data centers. These technologies include CFD, BFD, DLDP, Monitor Link, MAC SWAP, and EFM, each offering unique capabilities and operating principles tailored to different network contexts. Understanding their applications is vital for effectively identifying and addressing network faults, ensuring the uninterrupted performance of critical data center operations.

CFD

CFD (Connectivity Fault Detection), which adheres to the IEEE 802.1ag Connectivity Fault Management (CFM) standard, is an end-to-end per-VLAN link layer Operations, Administration, and Maintenance (OAM) mechanism utilized for link connectivity detection, fault verification, and fault location. It is a common feature found in networking equipment and protocols. Its primary function is to identify faults or disruptions in network connectivity between devices. Typically, it operates through the following steps: monitoring connectivity, expecting responses, detecting faults, and triggering alerts or actions. By continuously monitoring network connectivity and promptly detecting faults, CFD ensures the reliability and stability of network communications, facilitating quicker issue resolution and minimizing downtime.

BFD

BFD (Bidirectional Forwarding Detection) is a function that checks the survival status of the forwarding path between two adjacent routers, quickly detect failures, and notify the routing protocol. It is designed to achieve the fastest fault detection with minimal overhead and is typically used to monitor links between two network nodes. The BFD can be said to be an effective function when there is an L2 switch between adjacent routers and a failure occurs where the link status cannot be transmitted. FS offers a range of data center switches equipped with BFD functions, guaranteeing optimal network performance and stability. Opting for FS enables you to construct a robust and dependable data center network, benefiting from the enhanced network reliability facilitated by BFD.

DLDP

DLDP (Device Link Detection Protocol) is instrumental in bolstering the reliability and efficiency of Ethernet networks within data centers. Serving as an automatic link status detection protocol, DLDP ensures the timely detection of connection issues between devices. DLDP maintains the status of links by periodically sending messages, and once it detects any abnormality in the link, it promptly notifies the relevant devices and takes necessary actions to rectify the issue, ensuring network stability and reliability. This proactive approach not only enhances network stability and reliability but also streamlines fault troubleshooting processes within Ethernet-based data center networks, ultimately optimizing operational performance.

Monitor Link

Monitor Link is to trigger the change of the downlink port state by monitoring the change of the uplink port state of the device, thus triggering the switching of the backup link. This scheme is usually used in conjunction with Layer 2 topology protocols to realize real-time monitoring and switching of links. Monitor Link is mainly used in scenarios that require high network redundancy and link backup, such as in enterprise or business-critical networks that require high availability.

As the figure shows, once a change in uplink status is monitored, the Monitor Link system triggers a corresponding change in downlink port status. This may include closing or opening the downlink port, triggering a switchover of the backup link. In a data center network, Monitor Link can be used to monitor the connection status between servers. When the primary link fails, Monitor Link can quickly trigger the switchover of the backup link, ensuring high availability in the data center.

MAC SWAP

“MAC SWAP” refer to MAC address swap, which is a communication technique in computer networking. This involves swapping the source and destination MAC addresses during the transmission of data packets, typically performed by network devices such as switches or routers. This swapping usually occurs as packets pass through network devices, which forward packets to the correct port based on their destination MAC addresses.

However, the implementation of SANs comes with notable drawbacks, such as high initial costs, complex configuration and management requirements, necessitating specialized knowledge and technical support throughout their lifecycle.

In summary, DAS is like a large-scale portable hard drive, suitable for small environments or personal use; NAS is a storage device within a network, ideal for small businesses or households requiring file sharing capabilities; SAN is a network within storage devices, designed for high-performance, high-availability storage solutions for large enterprises and data centers.

Basics of Distributed Storage

From the organization structure of storage, storage can be divided into three types: direct attached storage (DAS), centralized network storage (NAS and SAN), and distributed network storage. Next, we will explore distributed storage in detail, examining its core principles, advantages, classifications and applications.

Distributed storage is a data storage architecture that disperses data across multiple independent physical storage devices (nodes) over a network, rather than centrally storing it on a single or a few devices like traditional storage. This technology is designed to enhance the scalability, performance, reliability, and efficiency of storage systems. Consequently, it is particularly suitable for handling large-scale data storage and access requirements.

Advantages of Distributed Storage

Distributed storage systems offer numerous benefits that make them a preferred choice for modern data storage needs, especially in large-scale and geographically dispersed environments. Here are some of the key advantages:

Reliability and Redundancy: These systems typically replicate data across multiple nodes, ensuring that even if one node fails, the data can still be retrieved from another node. This replication enhances the reliability and availability of the data. Additionally, distributed storage systems are designed to be fault-tolerant, allowing them to continue operating smoothly even in the event of hardware failures. For instance, if a data center is rendered inoperative due to a natural disaster, other data centers can still provide data access services, ensuring continuous availability.
Scalability: Distributed storage systems can easily expand storage capacity by adding nodes, an approach known as horizontal scaling. In contrast, centralized systems need to expand by adding capacity to individual storage devices, known as vertical scaling, which is typically less efficient and more costly. In addition, distributed storage systems can balance workloads across multiple nodes, preventing a single node from becoming a performance bottleneck. This scalability makes distributed storage suitable for a wide range of needs, from small businesses to large-scale Internet services.
Cost Efficiency: Distributed storage systems often utilize commodity hardware, which is more economical than specialized storage solutions. This reduces hardware costs and allows organizations to build large-scale storage systems using affordable equipment.
Improved Disaster Recovery: By storing data in multiple locations, these systems are better protected against natural disasters, power outages and other localized disruptions. Cloud storage providers typically back up data in different geographic locations to ensure high availability and security.

In summary, distributed storage represents a powerful and versatile solution for modern data management, offering significant advantages in reliability, scalability, cost efficiency, and disaster recovery.
