Best Practices

Best practices in enterprise environments dictate the elimination of single points of failure in server

installations; this includes all required resources: power, storage and networking. For purposes of this

document, we are assuming that both networking and power are redundant and configured correctly.

We are solely concerned with the implementation of Dell Compellent storage in an enterprise

environment with HP-UX 11i v3, v2 and/or v1 servers.

To that end, the optimum configuration for HP-UX servers accessing Dell Compellent storage consists of

at least one pair of Storage Center heads, two separate Fibre Channel (FC) fabrics and at least two

HBAs (host bus adapters) in each HP-UX server. There are major differences between the ‘mass

storage stack’ on HP-UX 11i v3 and all earlier versions of HP-UX; for that reason, this document is

written to address HP-UX 11i v2, v1 and 11.00 only, with the accompanying document “Dell

Compellent HP-UX Best Practices 11i v3” written to address the differences and nuances of v3

accordingly.

The above scenario will continue to function even if the HP-UX server may contain ONLY

one (1) FC port on a single FC HBA. In this latter scenario with limited hardware, all LUNs

from the Dell Compellent Storage Center are still presented in a redundant manner across each Dell
