I have a ADAPTEC AAR 2610SA 6-PORT SATA RAID 2610 CARD connected to a Dell Poweredge 2800.

Connected to the controller are 5 samsung 1tb disks.

I want to create a raid 5 array with the 5 disk, hoping to end up with a volume of 4tb, but when i do so, the controller make a raid 5 set of 2tb insteat of the 4tb i need.

Seem the i need to set the disks to GPT, but cant figure it out.

Any ideas

    What O/S are you running?  The biggie is that it may be a deal killer, as you can't boot off a GPT disk drive anyway ... FYI, unless you are running an Itanium system

    If you install OS onto one HDD and then configure the RAID5 then you can get almost 4TB GPT storage and 1 MBR partitioned HDD with OS on it.

    OS is already installed (windows 2k3 r2 x86), on a dell raid controller with 3 scsi drives.

    The aar-2610sa is a extra controller, drivers are installed
    also have i installed Adaptec Storage Manager 4.30
    with Adaptec Storage Manager is can create raid 5 arrays up to 2tb.
    Converting the drives to GPT in windows 2k3 r2 dos not help.

    Then looks like it is the limit of the card. Contact the vendor and check if the card can create configurations over 2048GB limit.
