What kind of raid is this

Hi our server has 4x 36gb hard drives, they all appear as one C: drive which is about 100gb. What kind of raid is that?

The server is a dell poweredge 2600 with 6 bays. Is is possible to leave these 4 drives as they are and add another two mirrored 160gb drives? So we would have 1x 100gb drive and 1x 160gb drive

If not are there any other options for keeping the 4 36gb drives as one and adding extra capacity. Thanks.

    Based on capacity it sounds like RAID 5, and yes you can add two more as you suggest.  You should be able to go into the raid configuration utility and verify what you have now.

    be carefull with running different speed rated drives on a dell perc controller, i have had problems with this in the past. you shoudl however be fine with as long as the two new ones are a seperate array.

    Hi, There

    It is very easy raid 5. to make just an easy configuration on the next 2 drives you want to configure.

    If you have Dell Array Manager installed just insert the 2 new drives while having the Array Manager started you will then see the 2 new drives here on the menu bar you click the create new virtuel drive or the new configuration / add view configuration click the 2 new drives and you will be asked if you want a raid 1. then afterwords you just need to initialize the drives "Array Manager" then format the new volume under windows.

    In case you do not have the Array Manager installed, upon reboot of the server use CTRL-M to go to the perc bios should be Perc 3/di.

    In here you will see a main menu

    Configuration-------View add configuration is what you need

    Then the Perc Controller is scanning
    now the 2 new drives should be "Ready"
    click twice on the space bar
    then Enter
    Space key again
    and it should say raid 1 ------- then you need to accept
    esc ---esc----- save configuration
    go to the main menu again -------initialize logical drive 1 as the first 4 disk you have as a raid 5 id logical drive 0....
    Restart go to windows format the drive under disk management...

    you can also download array manager from, you may not want to reboot the windows server.

    If you add the two drives of 160gb to de array you only be able to use more 72gb, because the RAID use the capacity of the disc with less capacity.

    If you want to use de full capacity of those discs, you can make a new array with them, and you will have one drive with 100gb and another with 160gb, or just use them as two separate discs, and you will have one drive with 100gb and two other with 160gb.
