In case of RAID1, 4 groups at maximum. Different capacity/rotation speed/disk type of internal drives can be mixed among different RAID groups. When configuring hot-spare disks, need to use same type of internal disk for the RAID group. All internal drives are same type, Global Hot Spare can be available. When mixing different capacity/rotation speed/disk type drives, need to use Dedicated Hot Spareper RAID group. With 2 RAID Controller configuration, max. 4 internal drives can be connected per one RAID controller.Therefore, RAID50/60 is not available with 2 RAID Controller configuration, With 2 RAID Controller configurations, RAID cannot be configured among internal drives under differentRAID Controllers. Please refer to “Internal Drive” of “Reference” section for the details about Internal Drive: Priority/Order ofInstallatioin.
