The task of ordering hardware should be deferred until after the OAM work load is analyzed and resource requirements are estimated (see Estimating resource requirements). Depending on the volume of objects to be processed and stored, you can order additional DASD (for DB2 and any zFS requirements), NFS file servers (if NFS is used), optical storage devices, or tape devices. An Object or Object Backup storage group can specify no more than eight optical libraries. Be sure to request appropriate documentation when you place the hardware order.
