We have a hp proliant server with 16gb memory and lsi sas 1068e raid controller on it. esxi 5.0
there are 4 sata disk connected to the controller and 2 raids 1 created
there are 2 win 2008 r2 servers installed. (one has 5gb memory other 6 gb) there are no problems with disk speed under them - benchmark shows 90-100mb/s read and 40-45mb/s write
the new installed from the scratch win 2003 sp2 r2 (3gb memory) server shows 60-70 mb/s read and 10-12 mb/s write on the same array
--
all options exept memory size (mentioned above) and scsi type (logical sas vs logical paralel) are the same. changing quantity of processors for the 2003 server (as i've read in some posts) didn't help
any solutions for that?
thanks in advance
