Description
NVMe (Non-Volatile Memory express) is a leading-edge SSD technology
where drives are directly attached to the PCI-e bus. Typical
SAS/SATA controllers are optimized for use with traditional
rotating hard drives, and as such can increase latency, and
reduce the bandwidth available to attached SSDs. Since
NVMe drives bypass a SAS/SATA controller, they can help
minimize/eliminate performance reductions often seen when using
these controllers with solid state storage. NVMe may become a
key building block in future applications that require
high-performance disk storage. This presentation describes the
testbeds used to evaluate this technology in the context of a
data center with a heterogeneous user community and a variety
of applications, and summarizes performance and the pros and
cons in the RACF environment.
