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.

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.

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.

Within the intricate network infrastructure of data centers, MAC address swapping is pervasive, occurring as packets traverse various network devices. This process guarantees the efficient routing and delivery of data, essential for maintaining seamless communication within both local area networks (LANs) and wide area networks (WANs) encompassed by data center environments.

Overall, MAC SWAP enables real-time monitoring of link status, providing timely link information and embodies flexibility to some extent, but may also introduce additional bandwidth overhead and have impact on network performance.

Effective storage is crucial for managing the growing volumes of data and ensuring secure, efficient access. As data centers evolve, reliable and flexible storage options are essential to meet the ever-changing demands of businesses. With this foundation, this article will start with traditional storage systems and move towards distributed storage fundamentals and their diverse applications.

Direct Attached Storage

Direct Attached Storage (DAS) refers to storage devices directly connected to a server, utilizing interfaces like SATA, SAS, and USB. It offers cost-effective and simple installation, with good performance for applications like operating systems and databases. However, DAS has limited scalability and challenges in resource sharing among servers. Additionally, server failures can impact storage access, highlighting the need for careful consideration in its implementation.

Centralized Network Storage

Unlike DAS, NAS and SAN storage is networked storage, where NAS has its own file system that can be accessed and used directly through a PC, while SAN does not have its own file system, but has dedicated switches that provide storage services to servers over a dedicated network.

NAS

NAS (Network Attached Storage) is a specialized storage server designed to provide file-level data access over a network. Connected through Ethernet, it enables access via protocols such as NFS and CIFS/SMB. NAS offers centralized management, facilitating easy sharing and good scalability for storage needs. However, compared to DAS, NAS typically incurs a higher cost. Furthermore, its performance is susceptible to network conditions, which can affect data access speeds. Despite these drawbacks, NAS remains a popular choice for organizations seeking efficient and centralized file storage solutions.

SAN

SAN (Storage Area Network) is a high-speed dedicated network designed to facilitate block-level data access, primarily tailored for enterprise-level applications. SANs typically utilize advanced technologies like Fiber Channel (FC) or Ethernet, establishing connections between servers and storage devices via protocols such as FC-SAN or iSCSI.

SANs also support data redundancy and robust disaster recovery mechanisms. 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. These advantages make it an essential component of enterprise storage architectures, capable of meeting the diverse needs of today’s data-driven organizations.

Vigorous efforts are being made by the cloud service providers and network infrastructure vendors to pace up the deployment. However, there are a number of challenges that can hamper its effective implementation and hence, the adoption.

In this article, we will have a detailed look into the opportunities and the challenges linked to the successful implementation of 400G Ethernet enterprise network. This will provide a clear picture of the impact this technology will have on large-scale organizations.

Opportunities for 400G Ethernet Enterprise Networks

Better management of the traffic over video streaming services
Facilitates IoT device requirements
Improved data transmission density

How can 400G Ethernet assist enterprise networks in handling growing traffic demands?

Rise of 5G connectivity

Rising traffic and bandwidth demands are compelling the CSPs for rapid adoption of 5G both at the business as well as the customer end. A successful implementation requires a massive increase in bandwidth to cater for the 5G backhaul. In addition, 400G can provide CSPs with a greater density in small cells development. 5G deployment requires the cloud data centers to be brought closer to the users as well as the devices. This streamlines the edge computing (handling time-sensitive data) part, which is another game-changer in this area.

Data Centers Handling Video Streaming Services Traffic

The introduction of 400GbE Ethernet has brought a great opportunity for the data centers working behind the video streaming services as Content Delivery Networks. This is because the growing demand for bandwidth is going out of hand using the current technology. As the number of users increased, the introduction of better quality streams like HD and 4K has put additional pressure on the data consumption. Therefore, the successful implementation of 400GbE would come as a sigh of relief for the data centers. Apart from rapid data transferability, issues like jitter will also be brought down. Furthermore, large amounts of data transfer over a single wavelength will also bring down the maintenance cost.

High-Performance Computing (HPC)

The application of high-performance computing is in every industry sub-vertical whether it is healthcare, retail, oil & gas or weather forecasting. Real-time analysis of data is required in each of these fields and it is going to be a driver for the 400G growth. The combined power of HPC and 400G will bring out every bit of performance from the infrastructure leading to financial and operational efficiency. 400G Ethernet

Addressing the Internet of Things (IoT) Traffic Demands

Another opportunity that resides in this solution is for the data centers to manage IoT needs. Data generated by the IoT devices is not large; it is the aggregation of the connections that actually hurts. Working together, these devices open new pathways over internet and Ethernet networks which leads to an exponential increase in the traffic. A fourfold increase in the data transfer speed will make it considerably convenient for the relevant data centers to gain the upper hand in this race.

Greater Density for Hyperscale Data Centers

In order to meet the increasing data needs, the number of data centers is also seeing a considerable increase. A look at the relevant stats reveals that 111 new Hyperscale data centers were set up during the last two years, and 52 out of them were initiated during peak COVID times when the logistical issues were also seeing an unprecedented increase. In view of this fact, every data center coming to the fore is looking to setup 400GbE. Provision of greater density in fiber, racks, and switches via 400GbE would help them incorporate huge and complex computing and networking requirements while minimizing the ESG footprint at the same time.

Easier Said Than Done: What Are the Challenges In 400G Ethernet technology

Below are some of the challenges enterprise data centers are facing in 400G implementation.

Cost and Power Consumption

Today’s ecosystem of 400G transceivers and DSP are power-intensive. Currently, some transceivers don’t support the latest MSA. They are developed uniquely by different vendors using their proprietary technology.

Overall, the aim is to reduce $/gigabit and watts/gigabit.

The Need for Real-World Networking Plugfests

Despite the standard being approved by IEEE, a number of modifications still need to be made in various areas like specifications, manufacturing, and design. Although the conducted tests have shown promising results, the interoperability needs to be tested in real-world networking environments. This would outline how this technology is actually going to perform in enterprise networks. In addition, any issues faced at any layer of the network will be highlighted.

Transceiver Reliability

Secondly, transceiver reliability also comes as a major challenge in this regard. Currently, the relevant manufacturers are finding it hard to meet the device power budget. The main reason behind that is the use of a relatively older design of QSFP transceiver form factor as it was originally designed for 40GbE. Problems in meeting the device power budget lead to issues like heating, optical distortions, and packet loss.

The Transition from NRZ to PAM-4

Furthermore, the shift from binary non-return to zero to pulse amplitude modulation with the introduction of 400GbE also poses a challenge for encoding and decoding. This is because NRZ was a familiar set of optical coding whereas PAM-4 requires involvement of extensive hardware and an enhanced level of sophistication. Mastering this form of coding would require time, even for a single manufacturer. from NRZ to PAM-4

Greater Risk of Link Flaps

Enterprise use of 400GbE also increases the risk of link flaps. Link flaps are defined as the phenomenon involving rapid disconnection in an optical connection. Whenever such a scenario occurs, auto-negotiation and link-training are performed before the data is allowed to flow again. While using 400GbE, link flaps can occur due to a number of additional reasons like problems with the switch, design problems with the -transceiver, or heat.

Inference

The true deployment of 400GbE Ethernet enterprise network is undoubtedly going to ease management for cloud service providers and networking vendors. However, it is still a bumpy road. With the modernization and rapid advancements in technology, scalability is going to become a lot easier for the data centers. Still, we are still a long way from the destination of a successful implementation. With higher data transfer rates easing traffic management, a lot of risks to the fiber alignment and packet loss still need to be tackled.

400G Optics in Hyperscale Data Centers

Since their advent, data centers have been striving hard to address the rising bandwidth requirements. A look at the stats reveals that 3.04 Exabytes of data is being generated on a daily basis. Whenever a hyperscale data center is taken into consideration, the bandwidth requirements are massive as the relevant applications require a preemptive approach due to their scalable nature. As the introduction of 400G data centers has taken the data transfer speed to a whole new level, it has brought significant convenience in addressing various areas of concern. In this article, we will dig a little deeper and try to answer the following questions:

What are the driving factors of 400G development?
What are the reasons behind the use of 400G optics in hyperscale data centers?
What are the trends in 400G devices in large-scale data centers?

What Are the Driving Factors For 400G Development?

The driving factors for 400G development are segregated into video streaming services and video conferencing services. These services require pretty high data transfer speeds in order to function smoothly across the globe.

Video Streaming Services

Video streaming services were already taking a toll on the bandwidth requirements. That, combined with the COVID-19 pandemic, forced a large population to stay and work from home. This automatically increased the usage of video streaming platforms. A look at the stats reveals that a medium-quality stream on Netflix consumes 0.8 GB per hour. See that in relation to over 209 million subscribers. As the traveling costs came down, the savings went to improved quality streams on Netflix like HD and 4K. What stood at 0.8 GB per hour rose to 3 and 7 GB per hour. This evolved the need for 400G development.

What Makes 400G Optics the Ideal Choice For Hyperscale Data Centers?

Significant Decrease in Energy and Carbon Footprint

To put it simply, 400G raises the data transfer speed four times. 400G reduces the cost of 100G ports as breakouts when comparing a 4 x 100G solution to facilitate 400GbE with a single 400G solution to do the same. A single node at the output minimizes the risk of failures as well as lower the energy requirement. This brings down the ESG footprint that has become a KPI for the organizations going forward.

Reduced Operational Cost

As mentioned earlier, a 400G solution requires a single 400G port, whereas addressing the same requirement via a 100G solution requires four 100G ports. On a router, four ports cost way more than a single port that can facilitate rapid data transfer. The same is the case with power. Combined together, these two bring the operational cost down to a considerable extent. 400G Optics
