- Improved Custom Scheduler Filter Functions There are now a significantly larger number of metrics exposed to the Cinder scheduler from the FlashArray which can be used in driver filter and/or goodness functions.
- TRIM/Discard/UNMAP You can now allow for Cinder volumes to get TRIM/Discard/UNMAP commands when used with VM's provisioned with libvirt (KVM, qemu, etc as supported by hypervisor).
- Automatic Volume Eradication New config option to allow for automatically eradicating Pure volumes upon deletion in Cinder. It is disabled by default.
