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 52 (page
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

Limitations

HP Continuous Access EVA 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.
