[openstack-dev] [cinder] about block device driver

Oh,the instances using Cinder perform intense I/O, thus iSCSI or LVM is not a viable option - benchmarked them several times, unsatisfactory results.Sometimes it's IOPS is twice as bad,could you show me your test data?Thank you!

The other reason for its removal was its inability to meet the minimum feature
set required for Cinder drivers along with benchmarks showing the LVM and iSCSI
driver could be tweaked to have similar or better performance.

The other option would be to not use Cinder volumes so you just use local
storage on your compute nodes.

Readding the block device driver is not likely an option.
