In a dual-link configuration, HP recommends that you limit the maximum sustained I/O load to 40% of the maximum available bandwidth for each link. This allows for instantaneous bursts of I/O activity and minimizes the effect of a link failure on performance.

In a dual-link configuration, HP recommends that you limit the maximum sustained I/O load to 40%
of the maximum available bandwidth for each link. This allows for instantaneous bursts of I/O activity
and minimizes the effect of a link failure on performance.
FCIP shared-link configuration
A shared-link configuration uses only one IP network (
Figure 85
).

NOTE:
Do not use the shared-link configuration if you require high availability because it does not provide
redundancy between fabrics. It can also decrease performance because the total bandwidth available
for storage is shared by the two fabrics.
