Hi Alfredo, Please take a look at SPDK: https://docs.openstack.org/cinder/latest/configuration/block-storage/drivers... https://spdk.io/ I can provide you with more information if you feel that this is the storage type you would like to use.

Of course must be: 1. Reliable 2. Fast 3. Capable of good performance over WAN given a good network back end Both open source and commercial technologies and ideas are welcome. Cheers -- Alfredo
