HP 1.10GB Virtual Connect Ethernet Module for c-Class BladeSystem - Manual (Page 93)

Storage management 93
Configuring Virtual Connect to assign WWNs in server blades maintains a consistent storage identity
(WWN) even when the underlying server hardware is changed. This method allows server blades to be
replaced without affecting the external Fibre Channel SAN administration.
CAUTION: To avoid storage networking issues and potential loss of data associated with
duplicate WWNs on a FC SAN fabric, plan carefully when allowing Virtual Connect to assign
server blade WWNs so that the configured range of WWNs is used only once within the
environment.

Automatic Login Redistribution is an advanced option that can be enabled for a Virtual Connect fabric. The
administrator can configure the link stability interval parameter on a VC domain basis. This interval defines
the number of seconds that the VC fabric uplink(s) have to stabilize before the VC FC module attempts to
load-balance the logins.
