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.5G

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.

Whatever the future holds, one is likely certain: 5G will provide far more than just a speedier internet connection. It has the potential to disrupt businesses and change how customers engage and interact with products and services.

What is 400G?

400G or 400G Ethernet is the next generation of cloud infrastructure that offers a four-fold jump in max data-transfer speed from the standard maximum of 100G. This technology addresses the tremendous bandwidth demands on network infrastructure providers, partly due to the massive adoption of digital transformation initiatives.

Additionally, exponential data traffic growth driven by cloud storage, AI, and Machine Learning use cases has seen 400G become a key competitive advantage in the networking and communication world. Major data centers are also shifting to quicker, more scalable infrastructures to keep up with the ever-growing number of users, devices, and applications. Hence high-capacity connection is becoming quite critical.

How are 5G and 400G Related?

The 5G wireless technology, by default, offers greater speeds, reduced latencies, and increased data connection density. This makes it an attractive option for highly-demanding applications such as industrial IoT, smart cities, autonomous vehicles, VR, and AR. And while the 5G standard is theoretically powerful, its real-world use cases are only as good as the network architecture this wireless technology relies on.

The low-latency connections required between devices, data centers, and the cloud demands a reliable and scalable implementation of the edge-computing paradigms. This extends further to demand greater fiber densification at the edge and substantially higher data rates on the existing fiber networks. Luckily, 400G fills these networking gaps, allowing carriers, multiple-system operators (MSOs), and data center operators to streamline their operations to meet most of the 5G demands.

5G Use Cases Accelerating 400G transformation

As the demand for data-intensive services increases, organizations are beginning to see some business sense in investing in 5G and 400G technologies. Here are some of the major 5G applications driving 400G transformation.

High-Speed Video Streaming

The rapid adoption of 5G technology is expected to take the over-the-top viewing experience to a whole new level as demand for buffer-free video streaming, and high-quality content grows. Because video consumes the majority of mobile internet capacity today, the improved connectivity will give new opportunities for digital streaming companies. Video-on-demand (VOD) enthusiasts will also bid farewell to video buffering, thanks to the 5G network’s ultra-fast download speeds and super-low latency. Still, 400G Ethernet is required to ensure reliable power, efficiency, and density to support these applications.

Virtual Gaming

5G promises a more captivating future for gamers. The network’s speed enhances high-definition live streaming, and thanks to ultra-low latency, 5G gaming won’t be limited to high-end devices with a lot of processing power. In other words, high-graphics games can be displayed and controlled by a mobile device; however, processing, retrieval, and storage can all be done in the cloud.

Use cases such as low-latency Virtual Reality (VR) apps, which rely on fast feedback and near-real-time response times to give a more realistic experience, also benefit greatly from 5G. And as this wireless network becomes the standard, the quantity and sophistication of these applications are expected to peak. That is where 400G data centers and capabilities will play a critical role.

The Internet of Things (IoT)

Over the years, IoT has grown and become widely adopted across industries, from manufacturing and production to security and smart home deployments. Today, 5G and IoT are poised to allow applications that would have been unthinkable a few years ago. And while this ultra-fast wireless technology promises low latency and high network capacity to overcome the most significant barriers to IoT proliferation, the network infrastructure these applications rely on is a key determining factor. Taking 5G and IoT to the next level means solving the massive bandwidth demands while delivering high-end flexibility that gives devices near real-time ability to sense and respond.

400G Network

What’s the Current and Future Trend of 400G Ethernet?

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.

Video Conferencing Services

As COVID-19 made working from home the new norm, video conferencing services also saw a major boost. Till 2021, 20.56 million people have been reported to be working from home in the US alone. As video conferencing took center stage, Zoom, which consumes 500 MB per hour, saw a huge increase in its user base. This also puts great pressure on the data transfer needs.

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

Trends of 400G Optics in Large-Scale Data Centers—Quick Adoption

The introduction of 400G solution in large-scale data centers has reshaped the entire sector. This is due to a humongous increase in the data transfer speeds. According to research, 400G is expected to replace 100G and 200G deployments way faster than its predecessors. Since its introduction, more and more vendors are upgrading to network devices that support 400G. The following image truly depicts the technology adoption rate.Trends of 400G Optics

Challenges Ahead

Lack of Advancement in the 400G Optical Transceivers sector

Although the shift towards such network devices is rapid, there are a number of implementation challenges. This is because it is not only the devices that need to be upgraded but also the infrastructure. Vendors are trying to upgrade them in order to stay ahead of the curve but the cost of the development and maturity of optical transceivers is not at the expected benchmark. The same is the case with their cost and reliability. As optical transceivers are a critical element, this comes as a major challenge in the deployment of 400G solutions.

Latency Measurement

In addition, the introduction of this solution has also made network testing and monitoring more important than ever. Latency measurement has always been a key indicator when evaluating performance. Data throughput combined with jitter and frame loss also comes as a major concern in this regard.

Investment in Network Layers

Lastly, the creation of a plug-and-play environment for this solution also needs to be more realistic. This will require a greater investment in the physical, higher level, and network-IP components layers.

Conclusion

Rapid technological advancements have led to concepts like the Internet of Things. These implementations require greater data transfer speeds. That, combined with the world going to remote work, has exponentially increased the traffic. Hyperscale data centers were already feeling the pressure and the introduction of 400G data centers is a step in the right direction. It is a preemptive approach to address the growing global population and the increasing number of internet users.

Global Optical Transceiver Market: Striding to High-Speed 400G Transceivers

100G NIC: An Irresistible Trend in Next-Generation 400G Data Center

NIC, short for network interface card, which can be called network interface controller, network adapter or LAN adapter, allows a networking device to communicate with other networking devices. Without NIC, networking can hardly be done. There are NICs with different types and speeds, such as wireless and wired NIC, from 10G to 100G. Among them, 100G NIC, as a product appearing in recent years, hasn’t taken a large market share yet. This post gives a description of 100G NIC and the trends in NIC as follows.

What Is 100G NIC?

NIC is installed on a computer and used for communicating over a network with another computer, server or other network devices. It comes in many different forms but there are two main different types of NIC: wired NIC and wireless NIC. Wireless NICs use wireless technologies to access the network, while wired NICs use DAC cable or transceiver and fiber patch cable. The most popular wired LAN technology is Ethernet. In terms of its application field, it can be divided into computer NIC card and server NIC card. For client computers, one NIC is needed in most cases. However, for servers, it makes sense to use more than one NIC to meet the demand for handling more network traffic. Generally, one NIC has one network interface, but there are still some server NICs that have two or more interfaces built in a single card.

100G NIC

Figure 1: FS 100G NIC

With the expanding of data center from 10G to 100G, 25G server NIC has gained a firm foothold in the NIC market. In the meantime, the growth in demand for bandwidth is driving data center to higher bandwidth, 200G/400G and 100G transceivers have been widespread, which paves the way for 100G server.

How to Select 100G NIC?

How to choose the best 100G NIC from all the vendors? If you are stuck in this puzzle, see the following section listing recommendations and considerations to consider.

Connector

Connector types like RJ45, LC, FC, SC are commonly used connectors on NIC. You should check the connector type supported by NIC. Today many networks are only using RJ45, so it may be not that hard to choose the NIC for the right connector type as it has been in the past. Even so, some network may utilize a different interface such as coax. Therefore, check if the card you are planning to buy supports this connection before purchasing.

Bus Type

PCI is a hardware bus used for adding internal components to the computer. There are three main PCI bus types used by servers and workstations now: PCI, PCI-X and PCI-E. Among them, PCI is the most conventional one. It has a fixed width of 32 bits and can handle only 5 devices at a time. PCI-X is a higher upgraded version, providing more bandwidth. With the emergence of PCI-E, PCI-X cards are gradually replaced. PCI-E is a serial connection so that devices no longer share bandwidth like they do on a normal bus. Besides, there are different physical sizes of PCI-E card in the market: x16, x8, x4, and x1. Before purchasing a 100G NIC, it is necessary to make sure which PCI version and slot width can be compatible with your current equipment and network environment.

Hot swappable

There are some NICs that can be installed and removed without shutting down the system, which helps minimize downtime by allowing faulty devices to be replaced immediately. While you are choosing your 100G NIC, be sure to check if it supports hot swapping.

Trends in NIC

NICs were commonly used in desktop computers in the 1990s and early 2000s. Up to now, it has been widely used in servers and workstations with different types and rates. With the popularization of wireless networking and WiFi, wireless NICs gradually grows in popularity. However, wired cards are still popular for relatively immobile network devices owing to the reliable connections.NICs have been upgrading for years. As data centers are expanding at an unprecedented pace and driving the need for higher bandwidth between the server and switches, networking is moving from 10G to 25G and even 100G. Companies like Intel and Mellanox have launched their 100G NIC in succession.

During the upgrading from 10G to 100G in data centers, 25G server connectivity popularized for 100G migration can be realized by 4 strands of 25G. 25G NIC is still the mainstream. However, considering the fact that the overall bandwidth for data centers grows quickly and hardware upgrade cycles for data centers occur every two years, the ethernet speed can be faster than we expect. 400G data center is just on the horizon. It stands a good chance that 100G NIC will play an integral role in next-generation 400G networking.

Meanwhile, the need of 100G NIC will drive the demand for other network devices as well. For instance, 100G transceiver, the device between NIC and network, is bound to pervade. Now 100G transceivers are provided by many brands with different types such as CXP, CFP, QSFP28 transceivers,etc. FS supplies a full series of compatible 100G QSFP28 and CFP transceivers that can be matched with the major brand of 100G Ethernet NIC, such as Mellanox and Intel.

Conclusion

Nowadays with the hyping of the next generation cellular technology, 5G, the higher bandwidth is needed for data flow, which paves the way for 100G NIC. On the occasion, 100G transceivers and 400G network switches will be in great need. We believe that the new era of 5G networks will see the popularization of 100G NIC and change towards a new era of network performance.
