WebA key result of this work is that strong consistency guarantees (per-key linearizability) need not compromise on performance. In a 9-node RDMA-based rack and with modest write ratios, our prototype design, dubbed ccKVS, achieves 2.2× the throughput of the state-of-the-art KVS while guaranteeing strong consistency.

WebRDMA transmission works in NICs with three queues: Send Queue (SQ), Receive Queue (RQ), and Completion Queue (CQ). When an RDMA application starts to work, it must create its SQ, RQ, and CQ in the RDMA NIC, and registers regions in memory for its processing. The work scheduling unit of RDMA is a Queue Pair (QP), which consists of one SQ and one RQ. Webbetween different types of RDMA network interface cards. We have made several changes to our network infrastructure to address these challenges. Today, around 70% of traffic in …
WebTo address these issues, t he creation of the RDMA Consortium was created; where RDMA technology enables a more efficient way of data transfer by removing the basic requirements of copies, operating system and, CPU involvement.

WebThe RDMA write IOPS and throughput performance are shown below. As can be seen, write throughput reaches 90 Gb/s or greater from IO sizes of 32K bytes and higher. The IOPS performance reaches about 450K IOPS from IO sizes of 16K bytes and lower. For both, the number of connections (ranging from 1 to 16) doesn’t affect results greatly. ... reach annex xvii phthalatesWebcess (RDMA) implements the entire transport logic in hardware network interface card (NIC) and allows di-rect access to remote memory, mostly bypassing CPU.
