Kontroler Raid PERC 4e/Di 256MB DDR2

Zestaw nie zawiera baterii oraz kabli SCSI.

The RAID controller recognizes and uses drive arrays created on existing PERC 3SCDCQC and PERC 4SCDC RAID controllers without risking data loss, corruption, redundancy or configuration loss. Similarly, the arrays created on the RAID controller can be transferred to other PERC 4 controllers.
