Windows Server (64-bit) configuration

Requirements

• Switch zoning or controller level SSP must be used to ensure each single path HBA has an

exclusive path to its LUNs.

• Single path HBA server can be in the same fabric as servers with multiple HBAs.

• Single path HBA server cannot share LUNs with any other HBAs.

HBA configuration

• Hosts 1 and 2 are single path HBA hosts.

• Host 3 is a multiple HBA host with multi-pathing software.

See Figure 34 (page 122).

NOTE: Single path HBA servers running the Windows Server 2003 (x64) operating system will

support multiple single path HBAs in the same server. This is accomplished through a combination

of switch zoning and controller level SSP. Any single path HBA server will support up to four single

path HBAs.

Risks

• Single path failure will result in loss of connection with the storage system.

• Single path failure may cause the server to reboot.

• Controller shutdown puts controller in a failed state that results in loss of data accessibility

and loss of host data that has not been written to storage.

NOTE: For additional risks, see “Windows Server failure scenarios” (page 132).

Limitations

• HP P6000 Continuous Access is not supported with single path configurations.

• Single path HBA server is not part of a cluster.

• Booting from the SAN is not supported on single path HBA servers.
