15.20 5XX Tape Device Rates with 571E & 571F Storage IOAs and 4327 (U320) Disk Units
Save/restore rates of 3580 Ultrium 3 (2Gb and 4Gb Fiber Channel) tape devices and of virtual tape
devices were measured on a 570 8-way system with 571E and 571F storage adapters and 714 type 4327
70GB (U320) disk units. Customer performance will be dependent on overall system resources and how
well those resources match the maximum capabilities of the device. See other sections in this guide about
memory, CPU and DASD.
