Overview
This can allow 5x faster bandwidth compared to using iSCSI TCP.
For example, over RAM device LUN I got ~1.3GBps Vs. ~5.5GBps (TCP Vs. iSER), and much lower CPU overhead.
The tests I ran and passed: create a volume, attach to VM, detach from VM, and delete the volume.
iSER (iSCSI over RDMA) Mellanox OpenStack support to Cinder
Instalation
Added two flags in "/etc/cinder/cinder.conf":
transport = iser (by default will be iscsi)
iser_ip_address = 192.168.20.140 (by default will be "iscsi_ip_address")
To apply the patch, replace the files under "cinder/volume":
driver.py
iscsi.py
And under "nova/virt/libvirt":
volume.py
see the patch details in "*.patch" files.
