Provider of semiconductor products that enable secure and intelligent processing for enterprise, data centre, cloud, wired and wireless networking, Cavium, has announced support for the newly ratified NVMe over Fibre Channel (FC-NVMe) 1.0 standard. Cavium’s QLogic 2700 series Gen 6 and 2690 series Enhanced Gen 5 Fibre Channel host bus adapters (HBAs) support connecting NVMe storage over Fibre Channel networks concurrently with the existing storage by using the updated firmware and drivers.
The new Cavium FC-NVMe drivers are targeted towards customers connecting flash-based storage arrays to servers over Fibre Channel networks. Pre-release software for the Linux OS is available for download by contacting Cavium Sales. Three usage scenarios are supported:
INCITS/T11 committee for Fibre Channel Interfaces recently approved the standard ensuring concurrent support and interoperability for FC-NVMe and the existing Fibre Channel protocols. Craig Carlson, Chairman of the T11 standards committee on FC-NVMe, said: “Cavium was a leading contributor to the definition and development of the FC-NVMe standard. Cavium actively participated by contributing resources and talent to the effort, and when the committee was investigating the new technology, Cavium engineers took many of the ideas and created POC code and provided valuable and timely feedback.”
Workloads that demand higher throughput, IOPs and lower latency are moving to flash. The NVMe protocol has been designed from the ground up for flash, and features deep parallelism, random access, and allows access to flash over PCI Express (PCIe) to maximise bandwidth. FC-NVMe extends these benefits over a Fibre Channel fabric. The low latency, lossless and efficient data handling capabilities of Fibre Channel are suited to extend the performance and latency advantages of NVMe over a network.
Key benefits of adopting Cavium Fibre Channel HBAs for Flash environments include:
“NVMe is a great advancement for the storage industry, driving down latencies and increasing IOPs. And FC-NVMe is an ideal storage protocol to take advantage of this technology transition. We believe Fibre Channel is the right choice for NVMe storage because of its deterministic performance, resiliency, reliability and ubiquitous presence in the data centre,” said Vikram Karvat, Vice President and General Manager, Cavium Fibre Channel Storage Group.
