SPDK v19.04.1: Maintenance Release

Jun 19, 2019 • Tomasz Zawadzki

On behalf of the SPDK community I’m pleased to announce the release of SPDK 19.04.1!

NVMe-oF

Increased default maximum number of queue pairs to 128 in order to match Linux kernel target. Users can still decrease this default when creating the transport (i.e. -p option for nvmf_create_transport in rpc.py).

Shared receive queue can now be disabled even for NICs that support it using the nvmf_create_transport RPC method parameter no_srq. The actual use of a shared receive queue is predicated on hardware support when this flag is not used.

iSCSI

Fixed hang on high QD large reads.

DPDK

Added DPDK 19.05 support.

raid bdev

Fixed race when issuing multiple destroy RPC for the same raid bdevs.
