2U COTS NVMe SSD optimizes I/O bandwidth and latency

Cheetah Storage’s NVME-SAN2N-24U2 is a 2U commercial off-the-shelf (COTS) Non-volatile Memory Express (NVMe) solid-state drive (SSD) that drives a high-performance NVMe flash server. It was designed to support standard Grantley Broadwell, Purley/Skylake, and AMD Naples platforms. The system was purpose-built for the NVMe Over Fabrics (NVMeoF) usage model with optimized I/O bandwidth and latency. Each central processing unit (CPU) manages one PEX9781 or PEX 9797 PCIe switch, while each PCIe switch manages 48x lanes downstream for 24x PCIe3 times four NVMe U.2 SSD drives.

The NVME-SAN2N-24U2 features a remote direct memory access (RDMA), as well as RDMA over Converged Ethernet (RoCE), and internet Wide-area RDMA Protocol (iWARP) network interface controller (NIC) adapters that are linked to NVMe SSDs via a PCIe switch. The system is designed to minimize crossing over QuickPath Interconnect/UltraPath Interconnect (QPI/UPI) links to avoid additional interruptions. The system can sustain over 500 Gps of I/O performance and can be delivered with customization options for original equipment manufacturers (OEMs).
