Configuring AIX systems for disk performance

Use JFS2 file systems for Tivoli® Storage Manager in most cases. Examine the queue depth for disks that are in use.

• Use JFS2 file systems for the Tivoli Storage Manager database, recovery logs, and disk storage pools, unless you are using disk for LAN-free operations. If you are using disk for LAN-free operations, then use General Parallel File System (GPFS™) for the shared storage pools.

  Use the JFS2 rbrw option on the mount command, especially if Tivoli Storage Manager database backups are stored to a FILE device class.

• The default queue depths for non-IBM disks that are used for Tivoli Storage Manager are often low by default. If the queue depth is less than 32, see the documentation for the disk system or contact the manufacturer about guidelines for the queue depth. To change the queue depth, see the AIX® product information.
