Cisco UCS Configuration Guide for vSphere – Part 4 – SAN

This is part 4 of the Cisco UCS Configuration Guide, covering the creation of Cisco UCS SAN policies.

Eight part series, describing how to configure a Cisco UCS from start to finish for a vSphere deployment:

The UCS Manager SAN configuration has five areas: SAN Cloud, Storage Cloud, Policies and Pools.  The diagram below shows the breakdown of those areas.

UCS SAN Overview

Configure SAN Policies

Before you begin, you will need the following:

  • Three Blocks of WWN Addresses for the nodes and virtual HBAs, one for Fabric A and one for Fabric B – for this exercise the ranges 20:00:00:25:B5:71:00:00 – 20:00:00:25:B5:71:00:63, 20:00:00:25:B5:73:1A:00 – 20:00:00:25:B5:73:1A:63 and 20:00:00:25:B5:73:1B:00 – 20:00:00:25:B5:73:1B:63 will be used.
  • Identify the FC Uplinks to SAN Fabrics A and B, in this example they are 1/27.
  • WWPNs of your Storage Array Service Processor ports.

To configure the Cisco UCS SAN Policies, you need to:

1. Access the “SAN” tab of the UCS Manager and expand the “SAN Cloud”.  Then select VSANs and right mouse click “Create VSAN”.


2. Configure two VSANs with the following settings.
