In most cases, Activity, TMF, FMTD, FMV, FMD, and PV show reasonable RCRs while DegSim, DegSim', RDMA
, and WDMA show poor RCRs.
Within this trend, there are many studies have started to leverage RDMA
technology to build ultra-low latency in-memory store.
Connecting storage directly to InfiniBand fabrics also allows applications to leverage InfiniBand's built-in support for RDMA
. This is particularly beneficial to HPC environments, allowing the applications to fetch data, compute, and put intermediate results into memory for other processes to complete the computation.
offload the adapters provide lower latency which supports the new generation of flash storage enabling the most efficient storage protocols such as SMB Direct, iSCSI Extensions for RDMA
(iSER), and NVMe Over Fabrics, all using fewer ports, cables, and switch ports than 10GbE.
NCI is the first CloudX deployment to take full advantage of RDMA
, OpenStack plugins, and Hypervisors offloads delivered by our end-to-end 40GbE Ethernet and 56Gb/s InfiniBand interconnect solution.
The OFED stack contains the drivers, the operating systems' interfaces and the upper level protocols that enable Linux to be RDMA
IBEx natively extends RDMA
enabled InfiniBand and Ethernet lossless networks and accelerates TCP/IP networking.
The Terminator 4 represents Chelsio's fourth generation TCP offload (TOE) design, third generation iSCSI design, and second generation iWARP RDMA
By utilizing BCM5708S remote direct memory access (RDMA
) functionality with BCM56580 cut-through switching, the Broadcom demonstration compares 1GbE blade server performance versus its complete end-to-end 2.5 Gigabit solution, resulting in significantly higher performance while leveraging the existing 1GbE backplane.
As examples, RDMA
and 10 Gb/s Ethernet are on the horizon and hold the promise of significantly expanding the adoption and implementation of IP SANs.
The new T6 adapters enable fabric consolidation by simultaneously supporting TCP/IP and UDP/IP socket applications, RDMA
applications and SCSI applications at wire speed, over legacy switching infrastructure, thereby allowing InfiniBand and Fibre Channel applications to run unmodified and concurrently over standard Ethernet in BSD, Linux and Windows environments.
Chelsio T6 100GbE adapters also offer the industry's lowest RDMA
over Ethernet (iWARP) latency at 1.2 micro-second user-space to user-space, with true kernel bypass, zero copy, and processing fully offloaded to the server adapter resulting in very low CPU utilization.
