Note: In order to store data at Wide Ultra3 SCSI speeds (160MB/sec), customers need three components:
Wide Ultra3 SCSI Adapter or Array Controller
Wide Ultra3 SCSI Hard Drives
Wide Ultra3 SCSI capable cable or server backplane
The ProLiant 6400R 500 MHz and 550 MHz Models are not configured with an Ultra3 SCSI capable cable. Therefore, customers are encouraged to purchase and install the Internal Ultra3 Cable Option Kit, HP (PN 166390-B21) when upgrading their server to use Wide Ultra3 SCSI Adapters, Array Controllers, and hard drives.
