HP BladeSystem c3000 enclosure considerations

Consider the following when using the HP BladeSystem c3000 enclosure:
The c3000 has four interconnect bays: 1, 2, 3, and 4. If Fibre Channel switch redundancy is
nl
required, use interconnect bays 3 and 4.
Interconnect bay 1 is dedicated to Ethernet or NIC connections; it cannot be used for Fibre
Channel connections.
Interconnect bay 2 can be used for Ethernet, NIC, or Fibre Channel connections; it is accessible
through the mezzanine 1 card only. If you use Fibre Channel connections from mezzanine 1 cards,
connect them to the interconnect bay 2 switch only, which provides port redundancy but not switch
redundancy.
Interconnect bay 2 cannot be used for VC-FC; it is restricted to Ethernet, NIC, or Fibre Channel
connections. VC-FC modules must use interconnect bays 3 and 4.
Interconnect bays 3 and 4 can be used for Fibre Channel connections and switch redundancy.
The full-height or half-height mezzanine 2 cards provide Fibre Channel port and switch redundancy.

HBA N_PortID Virtualization

HBA NPIV is a Fibre Channel standard that allows multiple N_Ports to connect to a switch F_Port.
HBA NPIV is used on servers running a VOS. You can assign a unique virtual port name to each VM
that shares the HBA. NPIV is supported on all 8 Gb and 4 Gb Emulex and QLogic HBAs when using
the vendor-supplied VOS drivers.

HBA NPIV considerations

Consider the following points when implementing a SAN with VOS servers using HBA NPIV:
You can assign and manage the virtual WWPN through the VOS. WWPN provides increased
security and integrity because you can create discreet zones based on the port name.
You must verify that the WWPNs in the SAN are unique. This is especially important for complex
SANs with heterogeneous VOSs.
You may need to enable HBA NPIV for some HBA and VOS combinations.
F_Port NPIV support differs for B-series, C-series, H-series, and M-series switches. For information
about setting up switches for use with HBA NPIV, see the switch documentation.
VMware ESX Server 3.5 is the only VOS with native support for HBA NPIV. The supplied Emulex
and QLogic drivers are NPIV enabled by default.
Each VOS may have restrictions or requirements for HBA NPIV. See the operating system
nl
documentation for information about setting it up for use with HBA NPIV.
If a VOS supports VM migration, the virtual WWPNs associated with the VM will migrate.
