14.5.1.3.3 JS12 Express and JS22 Express Configuration Considerations

1.The aggregate total of virtual disks (LUNs) will be sixteen at most. Many customers will

want to deploy between 12 and 16 LUNs and maximize symmetry. Consult carefully with your support team on the choices here. This is the most important consideration as it is difficult to change later. Consult also any available Best Practices manuals for a given SAN attached storage server.

2.The VIOS partition should be provided with between 1 and 2 GB of memory for disk-based usage's. If virtual LAN is a substantial factor, more memory may be required.
