Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/nimble-iscsi-volume-driver.

Description:

The purpose of this blueprint is to add an iSCSI Cinder volume driver for Nimble Storage. It will include the minimum set of features required by the Icehouse release.

Nimble Storage technology:
Nimble Storage is hybrid storage combining both flash SSD and near-line SAS disks.  The architecture is based on CASL (Cache Accelerated Sequential Layout) where random writes are coalesced in NVRAM + flushed to disks sequentially, with the flash/SSD as read acceleration cache.  CASL architecture provides non-disruptive upgrade for compute (processer/memory), cache (flash SSDs), capacity (disk shelves) as well as scale-out where up to four nodes of Nimble controllers can be clustered.  

Cinder volume driver:
The cinder volume driver for Nimble Storage will be based on the iSCSI protocol, allowing all minimal required operations in Icehouse release to work with Nimble Storage.
