FlexPod is a converged infrastructure solution that combines Cisco UCS servers and fabric interconnects with NetApp storage systems. It supports the provisioning of block (iSCSI) and file (NFS) storage volumes for use with an OpenStack cloud deployment using NetApp drivers. The document provides steps for creating volume types, provisioning NFS and iSCSI volumes from a NetApp storage system, and attaching the volumes to OpenStack instances to be used as block devices or mounted filesystems.

4. Upbringing 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!
