Hi, 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 Below screens from RAID Manager raid_01.png raid_02.png Should I just buy new BBU? or something else to check? Thanks...
