Apple WS 9650 Manuale Utente

 

 Basics

Ultra Wide SCSI - 28

 

JackHammer can transfer data through the Ultra SCSI-3 

portion of the card at rates up to 40 MB/s (as allowed by the 

SCSI-3 specification). The PCI portion of the card is capable 

of data transfer rate bursts up to 132 MB/s. This capability 

means the Workgroup Server 9650/233 and 9650/350 

can receive data as fast as the drives can provide it. Simply 

connecting the JackHammer•SE card to the SCSI drives 

improves their overall performance.

To ensure the best possible disk I/O performance, the WS 

9650 ships with all internal hard drives attached to the 

JackHammer•SE card via the 68-pin Ultra Wide SCSI cable. 

The WS 9650 allows for a total of four internal Ultra 

devices. Due to electrical signal limitations with Ultra 

devices, Apple Computer does not recommend connecting 

external devices to the JackHammer•SE card.
