Trend alert: RDMA goes the distance

It is still this time of year. a moment of reflection in the last 12 months. Nowadays, however, a year may seem like a decade or more, given the speed at which technology is breaking new ground, and in networking, it has been a great year for storage upgrades.

"What we saw, is that in 2017, direct access to remote memory, more commonly known as RDMA, became even more prevalent in the space storage, "says Anton Jacobsz, general manager of the African value-added distributor. , Unlimited networks.

He notes that RDMA is able to give network hardware the ability to directly transfer RAM data in one RAM machine to another – without involving the CPU – which makes it more attractive to those looking for low latency. and high speed communication. services.

"RDMA has wide appeal and is currently used in a wide range of industries such as high performance computing, financial and insurance services, and medical," continues Jacobsz. It is also used in innovative data-driven technologies, including machine learning, Web.2.0, big data and the cloud.

In addition, it is deployed in storage technologies such as Storage: NVMe-oF (bulk access to NVMe SSDs), iSER (iSCSI Extensions for RDMA), Luster, GPFS, HDFS, Ceph, EMC ScaleIO, VMware Virtual SAN, Dell Fluid Cache, Windows SMB Direct.

According to "RDMA Fabrics – Unlocking Enterprise Data Analytics" by Motti Beck, Senior Director, Business Development at Mellanox Technologies and Carl Tung, Product Line Manager at Broadcom, trends in these sectors "… will accelerate Adoption of technologies, including RDMA network protocols such as IB and RDMA over converged Ethernet (RoCE), in enterprise deployments As technologies such as NVMe (NVMe) and NVMe -over Fabrics are maturing, the gap between OLTP (On Line Transaction Processing) and traditional data warehousing is expected to shrink.In fact, several software vendors and platforms , such as IBM and Microsoft, are introducing new databases in memory for real-time analytics that are already pushing the infrastructure to the periphery.

In such applications, RDMA networking, in the form of RoCE-compliant Ethernet NICs with advanced unloads, will not only minimize latency, but also release processors to increase overall processing power. »(EnterpriseTech)

Mellanox is today one of the leading players in the RDMA space and the brand's technology solution is proudly distributed by Networks Unlimited in sub-Saharan Africa.
