This is my first post here so I would like to pass greeting to everybody.
I have a problem with machine
Fujitsu RX300 S5, 16GB RAM, Windows Server 2008, RAID 6 ( 5 disks 146 gigs ).
Role: Domain Controller, db server ( mssql 2008 ), only 20 users in AD
When I sow this machine for the 1st time I have impression that it`s performance is very poor.
I installed Raid Manager and it shows me that Backup Battery Unit is dead. So I bought a new one and installed it being full of hope that without BBU ( caching stuff ) this machine could work slow.
Yesterday I replace the BBU, and as you can guess nothing has changed.
I attached a screen shot from HD TACH. HD TUNE shows similar results.
RAID Manager does not show anything, just warning ( couple of days ago )
