[comp.unix.questions] Comments on Emulex SC7003 disk controllers, CDC 9772 disk drives

seb022@tijc02.UUCP (Scott Bemis ) (08/14/87)

Has anyone had the opportunity to use CDC 9772 disk drives with
Emulex's SC7003 disk controller on a VAX 8600 or 11/78X?  How do they compare 
to DEC's RA81 disk drives using an UDA50 disk controller?  Have you have
any serious problems with Emulex SC7003 disk controllers or CDC 9772
disk drives?  Please include your hardware - what type of VAX and the operating 
system you use (UNIX, Ultrix, VMS, etc). I am considering installing two CDC
9772 disk drives with an Emulex SC7003 disk controller on a VAX 8600 using the 
AT&T UNIX V Release 2.0 Version 2 operating system.  The current RA81 disk
drives with an UDA50 disk controller slow down the computer. Waiting on I/O is 
very high.
