Hi all!
We have met problem that EMC Symmetrix DMX 801 works too much slowly. Even more, second disk array, is connected to IBM p690, IBM FAStT 700, works in 2-3 times more faster.
We tested work with Oracle and with simple reading data on DMX and FAStT.
FAStT-700 speed 120MB/sec - 140 MB/sec
DMX-801 speed 20-40Mb/sec - the same as internal SCSI disk!!!!
Could anyone explain me what we must to do for improving performance of DMX?
Thanks
Yuri
