This topic describes the storage subsystems that are supported by the SAN File System.
SAN File System supports heterogeneous, simultaneously-connected Fibre Channel storage subsystems on clients with host bus adapter (HBA) sharing, subject to the limitations of the client platform, drivers, and storage vendors.
SAN File System supports an unlimited number of LUNs for user data storage. However, the amount of user data storage that you can have in your environment is determined by the amount of storage that is supported by the storage subsystems and the client operating systems.
Ensure that the IDs for any LUNs that are used by the system storage pool starts with 0. Refer to your storage documentation for information about assigning LUN IDs.
DS4000 LUNs assigned to user storage pools can be shared by multiple SAN File System clients as long as the clients are aware of one operating system type. LUNs within a DS4000 partition can only be used by one operating system. If you use DS4000 firmware lower than version 8.41, you cannot have more than 32 LUNs per partition.
Storage subsystems other than ESS or SAN Volume Controller may require additional, manual configuration to be detected and used by SAN File System.
Refer to the platform support documentation for a list of storage subsystems that are supported for each client platform in your environment.
