NVMe-oF SSD converter controller to enable optimal high performance
It has been announced by Marvell, that they are releasing the NVMe over Fabric (NVMe-oF) SSD converter controller, the 88SN2400, for cloud and enterprise data centers. The 88SN2400 controller is designed and optimized to convert an NVMe SSD into an NVMe-oF SSD, providing architecture that increases utilization and scalability of SSDs within the data center to ultimately lower total cost of ownership (TCO).
By bringing low latency access over the fabric and exposing the entire SSD bandwidth to the network, the Marvell controller supports true scalable, high performance disaggregation of storage from compute. The 88SN2400 utilizes a simple, low power and compute-less Ethernet fabric instead of a traditional PCIe fabric controlled and managed by an enterprise-class server SoC with integrated 100GE controllers.
As data growth continues to soar, data centers are grappling with the increasing power consumption, complexity, and costs associated with the demand for greater storage bandwidth and capacity. However, compute and storage continue to be underutilized, with storage servers typically oversubscribed, resulting in increased capital expenditure and operational expenditure. The Marvell SSD converter controller allows greater flexibility for data center operators and designers to develop their infrastructure and aims to enable them to meet evolving workload demands with optimized scalable units of disaggregated flash storage and storage class memory (SCM).
The SSD converter controller is powering an innovative class of low power, low latency and high performance Ethernet bunch of flash (EBOF) storage appliances. In a typical high end 2U24 shelf with Gen3x4 SSDs, the 88SN2400 can support up to 18M input/output operations per second (IOPS). Utilizing a Marvell Ethernet switch that supports 2Tbs and the Marvell 88SN2400, data center operators will be able to benefit from a 150GBs pipe of pooled storage, and better power consumption per IO compared to general purpose architectures.
The SSD converter controller is optimized for a small footprint and can be attached to existing backplanes providing ease of service and eliminating single point of failure. The technology can also be designed into future Marvell SSD and emerging SCM controllers.
Nigel Alvares, Vice President of SSD and Data Center Storage Solutions at Marvell, stated: “As cloud and enterprise data centers increase their deployments of flash storage and emerging storage class memories to address growing and diversifying workloads such as AI and analytics, it is paramount they optimize the utilization, efficiency and scale of these costly resources. Our converter controller enables disruptive disaggregated NAND and SCM SSD architectures that can be composed, provisioned and assigned real time to lower cloud and enterprise data centers total cost of ownership.”
Shigeo (Jeff) Ohshima, Technology Executive, SSD Application Engineering at Toshiba Memory Corporation, added: “Through our longstanding relationship with Marvell, we have shared a strong commitment to storage technology innovation. The development of our Ethernet direct attached NVMe-oF SSD prototype with the new Marvell 88SN2400 is built on our collaborative vision to help our data center customers achieve higher performance, lower cost and lower power consumption.”
John Chen, Vice President of TRENDFOCUS, concluded: “The Marvell 88SN2400 is the industry’s first NVMe-oF SSD converter controller technology providing an innovative solution to enabling NVMe-oF architectures with existing NVMe SSDs. The ability to expose the full SSD bandwidth to the network will enhance operational efficiencies and reduce costs in the data center. Leveraging the solution’s Ethernet feature will provide access to remote storage nodes with minimum added latency as compared to direct attached storage, making this solution a very interesting proposition for the industry.”
