Low Power DSP-Based Transceivers for Data Center Optical Fiber Communications

By Radha Nagarajan, SVP and CTO, Optical and Copper Connectivity Business Group

As the volume of global data continues to grow exponentially, data center operators often confront a frustrating challenge: how to process a rising tsunami of terabytes within the limits of their facility’s electrical power supply – a constraint imposed by the physical capacity of the cables that bring electric power from the grid into their data center.

Fortunately, recent innovations in optical transmission technology – specifically, in the design of optical transceivers – have yielded tremendous gains in energy efficiency, which frees up electric power for more valuable computational work.

Recently, at the invitation of the Institute of Electrical and Electronics Engineers, my Marvell  colleagues Ilya Lyubomirsky, Oscar Agazzi and I published a paper detailing these technological breakthroughs, titled Low Power DSP-based Transceivers for Data Center Optical Fiber Communications.

Marvell and Los Alamos National Laboratory Demonstrate High-Bandwidth Capability for HPC Storage Workloads in the Data Center with Ethernet-Bunch-Of-Flash (EBOF) Platform

By Khurram Malik, Senior Manager, Technical Marketing, Marvell

As data growth continues at a tremendously rapid pace, data centers have a strong demand for scalable, flexible, and high bandwidth utilization of storage solutions. Data centers need an efficient infrastructure to meet the growing requirements of next-generation high performance computing (HPC), machine learning (ML)/artificial intelligence (AI), composable disaggregated infrastructure (CDI), and storage expansion shelf applications which necessitate scalable, high performance, and cost-efficient technologies. Hyperscalers and storage OEMs tend to scale system-level performance linearly, driven by the number of NVMe SSDs that plug into the system. However, current NVMe-oF storage target Just-A-Bunch-Of-Flash (JBOF) architecture connects fast performance NVMe SSDs behind the JBOF components, causing system-level performance bottlenecks due to CPU, DRAM, PCIe switch and smartNIC bandwidth. In addition, JBOF architecture requires a fixed ratio of CPU and SSDs which results in underutilized resources. Another challenge with JBOF architecture is the scalability of CPU, DRAM, and smartNIC devices does not match the total bandwidth of corresponding NVMe SSDs in the system due to the overall system cost overhead and thus, impacts system-level performance.

Marvell introduced its industry-first NVMe-oF to NVMe SSD converter controller, the 88SN2400, as a data center storage solution application. It enables the industry to introduce EBOF storage architecture which provides an innovative approach to address JBOF architecture challenges, and truly disaggregate storage from the compute. EBOF architecture replaces JBOF bottleneck components like CPUs, DRAM and smartNICs with Ethernet switch and terminates NVMe-oF either on the bridge or Ethernet SSD. Marvell is enabling NAND vendors to offer Ethernet SSD products. EBOF architecture allows scalability, flexibility, and full utilization of PCIe NVMe drives.

Arm processors in the Data Center

By Raghib Hussain, Chief Strategy Officer and Executive Vice President, Networking and Processors Group

Last week, Marvell announced a change in our strategy for ThunderX, our Arm-based server-class processor product line. I’d like to take the opportunity to put some more context around that announcement, and our future plans in the data center market.

ThunderX is a product line that we started at Cavium, prior to our merger with Marvell in 2018. At Cavium, we had built many generations of successful processors for infrastructure applications, including our Nitrox security processor and OCTEON infrastructure processor. These processors have been deployed in the world’s most demanding data-plane applications such as firewalls, routers, SSL-acceleration, cellular base stations, and Smart NICs. Today, OCTEON is the most scalable and widely deployed multicore processor in the market.

How to Reap the Benefits of NVMe over Fabric in 2020

By Todd Owens, Technical Marketing Manager, Marvell

As native Non-volatile Memory Express (NVMe®) share-storage arrays continue enhancing our ability to store and access more information faster across a much bigger network, customers of all sizes – enterprise, mid-market and SMBs – confront a common question: what is required to take advantage of this quantum leap forward in speed and capacity?

Of course, NVMe technology itself is not new, and is commonly found in laptops, servers and enterprise storage arrays. NVMe provides an efficient command set that is specific to memory-based storage, provides increased performance that is designed to run over PCIe 3.0 or PCIe 4.0 bus architectures, and — offering 64,000 command queues with 64,000 commands per queue — can provide much more scalability than other storage protocols.

Navigating Product Name Changes for Marvell Ethernet Adapters at HPE

By Todd Owens, Technical Marketing Manager, Marvell

Hewlett Packard Enterprise (HPE) recently updated its product naming protocol for the Ethernet adapters in its HPE ProLiant and HPE Apollo servers. Its new approach is to include the ASIC model vendor’s name in the HPE adapter’s product name. This commonsense approach eliminates the need for model number decoder rings on the part of Channel Partners and the HPE Field team and provides everyone with more visibility and clarity. This change also aligns more with the approach HPE has been taking with their “Open” adapters on HPE ProLiant Gen10 Plus servers. All of this is good news for everyone in the server sales ecosystem, including the end user. The products’ core SKU numbers remain the same, too, which is also good.
