Kalray Demos NVMeOF Direct SSD With SK Hynix

Built around 13 SKHMS M.2 PCIe carriers

Kalray Inc., provider of acceleration solutions for data centers, will demonstrate a complete NVMeOF (Non-Volatile Memory express over Fabrics) chain from compute node to remote NVMe SSDs with SK Hynix Inc., manufacturer of DRAM, flash memory and SSDs, at the Flash Memory Summit.

The remote storage system will be built around 13 SKHMS M.2 PCIe Carriers integrating 4 SKHMS PE3110 SSDs each and 6 Kalray smartNIC KONIC-80 equipped with Kalray’s MPPA2-256 Bostan high speed I/O processor.

Data center storage is going through a major disruption with the massive introduction of SSDs, which have much lower latency than HDDs. SSD usage is putting pressure on the system to decrease the latency in the transport of data, as well as in the controller itself.

The NVMe protocol has been developed to take advantage of the random access property of SSDs and is already well established.

The second step is to introduce, before the end of the year, solutions based on the NVMeOF protocol, which carries NVMe commands and data over Ethernet using RDMA protocol such as RoCEv2 (RDMA over Converged Ethernet).

We have ported the RoCEv2 protocol from our partner 6WIND on our SmartNI, the KONIC80, recently introduced in the market, which makes it, with the addition of the NVMe Direct capability already available, an ideal solution for remote low latency SSD storage,” said Eric Baissus, Kalray’s CEO.

This demonstration is a major step toward the goal of introducing NVMeOF solutions as soon as possible by demonstrating a full NVMeOF chain from initiator down to SSD going through Ethernet with the active collaboration of two major players in this market,” said VP SooHwan Choi, head of the NAND product planning office, SK Hynix.

SK Hynix’s 1TB NVMe enterprise SSD is based on its own 2nd generation 3D NAND flash and in-house controller. This 3D NAND based NVMe SSD supports PCIe Gen 3×4 lanes, providing higher bandwidth and lower latency to process data far quicker than SATA SSDs.

Presented in a M.2 form factor, the product is for open cloud servers and in compliance with OCS (Open Cloud Server), v2.1.

In addition, since most of the datacenter servers presented lately by OCP (Open Compute Project) have installed PCIe NVMe SSDs, the importance of NVMe SSDs in the market is expected to increase gradually.

The SSD operates at 1,700MB/s with 750MB/s of sequential R/W and runs a random R/W at 160,000 IO/s and 30,000 IO/s.

Kalray’s industry solutions deliver these SmartNIC storage functions at sub-30W power consumption, while having the capability to simultaneously implement any type of processing required in storage applications, such as logical volume management, deduplication, encryption, compression and erasure coding – all in C/C++ software.

The company is planning to introduce a complete family of NVMeOF storage solutions including a SmartNIC with NVMe Direct capability but also an integrated low cost NVMe SSD controller capable of 3.2 million IO/s @ 4Kb data at 10µs latency, by the end of the year. These solutions can be found installed in data centers in 1Q17.

The solutions are all powered by Kalray’s MPPA2-256 Bostan high speed I/O processor, which has an architecture by connecting high speed I/O interfaces such as 2 x 40GbE and 2 x 8-lanes PCIe Gen3 directly to a large matrix of 256 computing cores, 16 system cores, 16 master cores all C/C++ programmable and 128 crypto coprocessors.
