Best Practices for HP BladeSystem Deployments using HP Serviceguard Solutions for HP-UX 11i (May 2010)

Due to the limited number of available interconnect module slots in the c3000, it is not possible to
configure the enclosure for complete redundancy to eliminate a Mezzanine card and interconnect
module as a single point of failure between the server blade and connectivity to the outside system
infrastructure. This is an important point to consider when deploying mission-critical environments an
whether this configuration will meet defined availability requirements.
