RDMA Requirements for High Availability in the NVM Programming Model | SNIA

Abstract

The SNIA NVM programming model includes actions that assure durability of data in persistent memory. New work is now in progress on remote access to NVM in support of high availability for persistent memory. While RDMA is an obvious choice of technologies for this purpose, certain challenges arise with single microsecond latencies for remote synchronization of small byte ranges. This presentation describes the work the SNIA NVM Programming Technical Working group on RDMA requirements for highly available persistent memory.

Learning Objectives

Understand the role of RDMA in highly available persistent memory
Understand how this use of RDMA differs from typical usage in HPC and storage systems
Understand new requirements placed on RDMA and the potential roles of hardware and software in addressing them
