tape drive: $5,300 (unit price), $26.50 (ASP$/GB)
The HP Kayak XU PC Workstation features support for up to two processors; CL2 ECC SDRAM memory, the most advanced in the industry; expandability of up to 1GB, the maximum supported by Intel's 440BX AGPset; HP FastRAID; and the world's fastest hard-disk drives, Fast Wide Ultra SCSI
10,000 rpm 4.5GB or 9GB Seagate Cheetah drives.
We have a SpectraLogic Gator/64000 (HVD) tape library that we want to connect to an IBM RS/6000 with a PCI Differential Ultra SCSI
(Type 4-L) adapter (IBM Feature Code 6207).
A: Yes a device with an Ultral60 SCSI interface can be placed on a Wide Ultra SCSI
host adapter as long as the Ultra SCSI
host adapter is single ended (SE) and not differential (HVD).
But the format works as spec'd; the drives are all Ultra SCSI
now, and Fujitsu was busy promoting them at Macworld.
High Voltage differential devices include some disk drives up to Ultra SCSI
speeds, tape drives, RAID boxes, and adapters such as the AHA2944UW or equivalent.
Q: Does a Fast SCSI CD-ROM slow down the speed of Ultra SCSI
hard disks, if they are connected on the same cable?
Internal Ultra SCSI
(CRW2100S), external Ultra SCSI
(CRW2100SX), and IEEE 1394 "FireWire" (CRW2100IX) versions were slated for release by year's end.
[and] as you add more drives to your system you'll appreciate the fact that SCSI doesn't hog interrupts like IDE does." Marti recommends installing "two or more" 10,000-rpm drives from IBM, Quantum or Seagate on an Ultra SCSI
card: specifically Adaptec model 29160.
drives in single ended mode (released two SCSI generations ago, and therefore are somewhat hard to find) runs at either 40MB/sec for wide or 20MB/sec for narrow.
Q: Can my Fast SCSI (narrow) adapter work with Ultra SCSI
As a rule, Fibre Channel data transmission is about three times faster than SCSI cables, although so-called Ultra SCSI
cables are also capable of high speed.
