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 2003, Windows 2000, and Windows XP Professional
x32” on page 74.
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.
