Any mid-range array with SATA disks configured as RAID6 (150-200MB/sec) should be enough as regardless of where the deduplication is done (client or media server), deduped data is sent/written to the disk array. Be aware that connection between disk array and media server has to be FC based. iSCSI is currently not supported for dedupe disk.

There is no way to directly convert the traditional disk based STU to deduped one. You need to first create a dedupe pool then you'll be able to have a separate STU for deduplication.

Have a look at the following TN:

Does anyone running NetBackup DeDupe (Media server, not dedicated puredisk) have any storage recommendations? We use 500GB SATA disks here as the basis for our DSSU / D2D2T infrastructure and I need to know if we can "convert" them to DeDupe storage as is, or if we need to invest in something that is more friendly to random I/O.

Thanks,
