Some NVMe-oF Implementations Require Network Forklift Upgrades. Solarflare’s NVMe-oF Works With Your Current Ethernet Network.
Scale Out Flash Storage (SOFS) is the concept of presenting flash storage from hundreds or thousands of industry-standard servers as a single storage image or namespace. Also known as disaggregated flash storage, SOFS has been adopted by hyperscale cloud providers, enterprises, and service providers as a way of getting the best of both local flash storage performance, and “centralized” storage management. With the advent of new technologies such as Non-Volatile Memory Express over Fabric, SOFS now has the potential of achieving the low latencies of local flash storage. Solarflare XtremeScale adapters help SOFS realize this performance, without the hassles of RDMA.
Solarflare’s NVMe-oF Stack: Lower Latency, Lower Cost, Easy to Deploy
The Problem: RDMA Latency
While RDMA’s OFED stack reduces I/O copies, it introduces other latencies, and is CPU inefficient. Worse yet, it required switches with data center bridging (DCB), significantly increasing the cost of switching infrastructure.
The Solution: Solarflare TCP NVMe-oF
Solarflare’s NVMe-oF stack utilizes TCP instead of RDMA. When combined with our cut-through technology, the result is lower latency than RDMA-based NVMe-oF transports, lower CPU utilization, and the ability to use low-cost L2 Ethernet switches.
