The 88SN2400 controller is optimized to convert an NVMe SSD into an NVMe-oF SSD

Data centers
are facing similar challenges, including higher costs associated with greater
power consumption or the disparate ratio between the growing demand for and
dwindling supply of bandwidth. Providing greater scalability of disaggregated
flash storage and storage class memory will go a long way toward addressing
these challenges. Marvell recently
unveiled what it claims to be the industry’s first non-volatile memory express
over fabric — or NVMe-oF — solid-state drive (SSD) converter
controller optimally designed for cloud and enterprise data centers.

The 88SN2400 controller is engineered to convert standard NVMe SSDs into NVMe-oF
SSDs by providing low-latency access over the fabric and bringing the entire
SSD bandwidth to the network. The controller eschews the more traditional peripheral
component interconnect express (PCIe) fabric for a low-power Ethernet fabric,
allowing for better scalability and utilization while reducing total cost of
ownership.

The 88SN2400
supports up to 18M input/output operations per second (IOPS). Using a Marvell
Ethernet switch that supports 2 Tb/s and the 88SN2400, the solution delivers a 150-GB/s
pipe of pooled storage, thereby providing a better rate of power consumption
per I/O than comparable devices that implement more traditional architectures.

”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 that they optimize the utilization,
efficiency, and scale of these costly resources,” according to Nigel Alvares, vice president of SSD and Data Center
Storage Solutions at Marvell. “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.”

The SSD
converter controller can be attached to existing backplanes, providing ease of
service and eliminating single point of failure, said Marvell. The company believes
that its new controller will be implemented in low-power, high-performance
Ethernet Bunch of Flash (EBOF) storage applications. Samples are available now.
