What is FlexPod?

FlexPod

Be Flexible!Be Multitenant!Be high available!Use multi protocol!Use the force FlexPod!There is no spoon Flexpod!OpenStack is your best friend!

Upbringing FlexPod

The friendship

Yeah, OpenStack is my

best friend! BecauseI provide Cinder backend

services for NFS and iSCSI. FlexPod

NFS & iSCSI both 7mode and Cluster mode

How can I do that?
