FCSM-based BladeCenter Connectivity
FC Port Types
Figure shows an example of N_Ports , F_Ports and E_Ports in a FibreChannel Switch Module connection.
Interoperability issues have to be considered when connecting FCswitches to each other.
Typically vendors are charging additional license fees for ISL and trunking
capabilities.

IPM-based BladeCenter Connectivity
FC Port Types
Figure illustrates a port mapping example of a Intelligent Pass-thru Module that connects blade servers to the external fabric.
IPM transparently representsHBA N_Ports to the external
fabric.
Therefore Interoperabilityissues are eliminated.
Nothing have to be changed.
Everything is handled by the
IPM.
At least at the price of FullFabric Switch.

IPM Advantages
IPM vs OPM
If you have large Fibre Channel fabrics using OPM
connections can yield a lot of cables , SFPs , andphysical ports (28 for each BladeCenter) if youchoose the use of OPMs.
IPM uses NPIV technology, which means that theinternal server ports (up to 14) are mapped to the
six external ports. Extensive cabling , largenumber of SFPs , and costly switch portlicenses are no longer required .

IPM Advantages IPM vs FCSM
If you have large Fibre Channel fabrics using aFCSM can yield to a lot of domainadministration , where each switch gets its owndomain ID with the use of Fibre Channel switchmodules.
Due to the implementing of transparent switching,all standard management features , such asname server table , zoning , and domain ID
administration, are fully removed from theFCSM . This transparentness enables easyadministration by either a SAN or a server
administrator .

Intelligent Pass-thru Module does not present aDomain
Only thing presented are the devices to the coreIn the IPM these are initiators.Management of the SAN is contained in the core
This allows the SAN administrator to have a much more
concentrated view of the management of the SAN for taskssuch as zone changes for backup and adding servers andstorage
Management considerations such as Name Server,
zone merges, and interoperability are contained in thecore thereby lessening the difficulty of management.
