Trusted Meets Fast
Technological advances in the enterprise data center involving Non-Volatile Memory
Express (NVMe)-based Solid-State Storage (SSS) devices are allowing many folks to change
their perception of Fibre Channel. I use the word “perception” because I am well aware of
the view of some that casts a shadow on the future of Fibre Channel. But I have to say that
from my vantage point, Fibre Channel still has a lot of life left in it. I’m reminded of the Mark
Twain attribution that “the rumors of my death have been greatly exaggerated!” Fibre
Channel is still the most trusted and reliable protocol for storage traffic. It is still evolving
and innovating, as evidenced by the recent advent of NVMe over Fibre Channel (FC-NVMe).
Earlier this week at the Gartner Data Center, Infrastructure and Operations Management
Conference, a QLogic and Brocade team demonstrated the industry’s first FC-NVMe solution
in conjunction with Brocade Gen 5 (16Gb) Fibre Channel fabric. (Read the press release
here.) The demo showcased live NVMe transport over Fibre Channel using QLogic Enhanced
Gen 5 (16Gb) Fibre Channel Adapters and a Brocade Gen 5 (16Gb) switch, connecting an
Intel PCIe SSD DC P3700 Series to a white-box Grantley-based server.
It was exciting to showcase this marriage as a proof of concept (POC) at the Gartner
conference because it fanned the flame of Fibre Channel’s relevance and created new
conversations around the requirements to optimize flash-based storage.
Fibre Channel and NVMe: Trusted Meets Fast
It was less than a handful of years ago when we saw the birth of the first native “all-FLASH”
solid state drives (SSDs) interface in the NVMe 1.0 specification. It was then just 18 months
ago when the NVM Express.org consortium set out to adapt this “local” PCI Express (PCIe)-
based interface to a fabric-capable transport able to deliver its efficiency to Storage Area
Networks (SANs). Fibre Channel, which plays a vital role in today’s SAN-based interconnect,
naturally followed suit. This is when “Trusted” met “Fast.”
Fibre Channel has been the dominant protocol used to connect servers with remote shared
storage comprising of hard disk drives (HDDs) and flash-based SSDs. It is trusted by 90
percent of Fortune 1000 data centers as the de facto standard for storage networking.[1]
NVMe is a standard interface for PCIe based SSD drives, and was designed from the ground
up for use with flash. Flash is fast. NVMe can make it even faster. This is a huge boost for the
low latency requirements of memory-intensive workloads.
FC-NVMe extends the simplicity and efficiency of NVMe by transferring NVMe commands
and structures end-to-end, requiring no translations. Fibre Channel’s purpose-built,
2. dedicated storage transport along with its parallelism and battle-hardened reliability make it
an ideal transport for NVMe.
If you’d like to dive in deeper, we’ve published a new QLogic white paper that details the
evolution of NVMe, explains the differences between NVMe and SCSI, outlines the key
attributes of the NVMe interface, and illustrates the native transport capability of NVMe
with full backward compatibility.
In summary, let me highlight a few key FC-NVMe benefits here:
3. Efficiency of NVMe is extended into the fabric
Reliability, availability and serviceability of Fibre Channel is ensured for next
generation storage applications
Lossless and secure fabric is available for high speed NVMe access
Existing Fibre Channel investments can be leveraged when deploying FC-NVMe
Deterministic performance, inherent low latency and high IOPS of Fibre Channel
aligns with NVMe requirements and roadmap
Based on open standards
It was obvious to all of us who viewed the FC-NVMe demo at the Gartner conference that
this is a game-changing storage standard for PCIe-connected drives and the future of
flash/SSD storage. It targets the performance, application response time, and scalability
needed for next generation data centers, while leveraging existing Fibre Channel
infrastructures. It’s why we’re jumping in early to pioneer the effort, taking a leadership
role in terms of FC-NVMe standards, and working with our partners to get this solution into
your fabric soon, which, we believe, will yield significant operational benefits to data centers
and IT managers.
