Today Bright Computing announced that its OpenStack management software integrates with Ceph to provide OpenStack with highly available and self-healing storage backend for volumes and objects.
“In this session we describe how GPUs can be used within virtual environments with near-native performance. We begin by showing GPU performance across four hypervisors: VMWare ESXi, KVM, Xen, and LXC. After showing that performance characteristics of each platform, we extend the results to the multi-node case with nodes interconnected by QDR InfiniBand. We demonstrate multi-node GPU performance using GPUDirect-enabled MPI, achieving efficiencies of 97-99% of a non-virtualized system.”
“100% Flash in the Datacenter? It won’t happen any time soon. Many (most?) tier one workloads will be moved to flash of course, but data is adding up so quickly that it’s highly unlikely you will be seeing a 100% datacenter any time soon. It will take a few years to have about 10/20% of data stored on flash and the rest will remain on huge hard disks (cheap 10+TB hard disks will soon be broadly available for example).”
