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.
System storage pool
Currently,
SAN File System supports only these storage subsystems for use in the system
storage pool:
- The IBM® TotalStorage® Enterprise Storage Server® (ESS), models 2105-F20 and 2105-800
- The IBM TotalStorage SAN
Volume Controller, model 2145 with storage subsystems that are supported by
SAN Volume Controller
- IBM FAStT
600T, 700, and 900 running firmware version 8.4 on the storage device and
software version 8.41 on the client platforms
Note: 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.
User storage pool
For user
storage pools, SAN File System is designed to work with FCP-compliant storage
subsystems that meet the following qualifications:
- Conforms to SCSI standards for device driver interface, including unique
device identification.
- Supports the required device drivers and operating-system stack.
- Are SAN-attached to the client machines.
Tip: Consider any restrictions imposed by the storage
subsystem, host bus adapter (HBA) cards, device drivers, and client platforms
that will be used in your SAN File System environment to ensure that they
are all compatible.
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.
