.Part 3 Host and Storage System Rules HP SAN Design Reference Guide 785353-001

Common SAN coexistence
To configure different HP storage system types or third-party storage systems for coexistence in a
common SAN, without common access from the same server, define a separate zone for each
storage system family. Storage system families include:
• P2000, MSA
• P6000, EVA
• P9500, XP
• 3PAR StoreServ 10000/7000; 3PAR F-Class, T-Class
• SVSP
• Third-party storage systems
To configure common server access to different storage system types, see “Common server access,
different storage system types” (page 209).
Common server access, different storage system types
Common server access enables simultaneous connectivity to different storage system types from
the same server. In some cases, connectivity to different storage system types, including disk and
tape, is allowed from the same HBA.
For supported common server access configurations and rules, see the storage solutions
documentation.
Common server access to HP storage and third-party storage is supported if you comply with the
following rules:
• You must use HP-supported HBAs, parameter settings, drivers, and firmware to support HP
storage and third-party storage on the same HP or multi-vendor server.
• Use different HP-supported HBA vendors if the required parameter settings, drivers, and
firmware are different for HP storage and the third-party storage.
Common server, common HBA
Simultaneous access to different storage system types from the same HBA is supported for some
storage systems. Each storage system must support identical:
• HBA model numbers and firmware versions
• Operating systems driver versions and parameter settings
• Multipathing software versions or compatible multipathing products
See the storage system, HBA, and multipath software coexistence table specific to each operating
system beginning with “HP-UX SAN rules” (page 191).
Common server, different HBAs
For information about supported storage system types using common server access with different
HBAs (Emulex and QLogic only), see the storage system, HBA, and multipath software coexistence
table specific to each operating system beginning with “HP-UX SAN rules” (page 191).
NOTE: HP Brocade-branded HBAs are not supported for coexistence with other vendor HBAs.
For all multipath configurations, all paths for a given LUN must only be accessed by HBAs from
the same vendor (for example, Emulex or QLogic, but not both).
