Accelerating PMEM Device Operations in Ceph with Hardware-based Memory Offloading

SNIAVideo via YouTube

Overview

Explore a technical conference talk from SNIA SDC 2022 that demonstrates how to reduce CPU pressure in data centers through hardware-based memory offloading devices when working with persistent memory (PMEM). Learn about implementing memory offloading solutions in two specific workload scenarios: storage applications using the SPDK framework and Ceph's bluestore with PMEM devices. Discover the design and implementation process of a new block device based on persistent memory and SPDK acceleration framework utilizing Intel's IOAT and DSA technologies. Examine the modifications required in bluestore's pmem module and understand the challenges and solutions for achieving offloading via DSA. See concrete performance improvements, including increased IOPS and decreased latency, in storage applications based on the SPDK framework.
