Up to 12 x 3.5-inch Drives plus 2 x 2.5-inch Drives

NOTE:

 An optional RAID controller occupies one PCI slot.

 All hard drives within a RAID array should be of the same capacity and rotation speed. Also, hard

drives in the back side (slot 12 to 13) must be in a separate RAID array than RAID arrays of hard

drives in the front side (slot 0 to 11) for configuration 4.3.4 to 4.3.6.

 Dedicated Hot Spare / Global Hot Spare are supported by using RAID controller card (PCI Express).

However, Global Hot Spare is not supported on the configuration 4.3.4 to 4.3.6. Also, hard drives in

the back side cannot be used as Hot Spare drives of a RAID array of hard drives in the front side and

front side drives cannot be used as Hot Spare drives of a RAID array of hard drives in the back side.

 Up to two kinds of drives can be mixed in a HDD cage.

 To configure a large-capacity RAID array, it is recommended to configure in RAID 6 or RAID 60 in

order to minimize the risk of becoming multiple hard drives failure during the RAID rebuilding process.

 It is recommended to set RAID array configuration drives less than eight in order to minimize the risk

of becoming multiple hard drives failure.

 For optional RAID controller driver to install Windows Server 2003 R2, download from the NEC
