4 Internal Hard Disk Drives
4.1 RAID Configuration
Refer to the section in accordance with your disk form factor and RAID configuration.
4.1.1 2.5-inch Drive Model
Refer to the section in accordance with your OS and RAID configuration. For example, when you would like
to configure RAID 0/1/10 1GB cache with Windows Server 2012 R2, refer to the section 4.2.1 for the
required components and then refer to the section 4.3.2 for the hard drives.

NOTE:
 All drives within a RAID array should be of the same type, capacity and rotation speed. Also, hard
drives in the back side (slot 24 to 25) must be in a separate RAID array than RAID arrays of hard
drives in the front side (slot 0 to 23) for configuration 4.2.1 to 4.2.3.
 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 4.2.1 to 4.2.3. 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 selected from SAS 10K HDDs, SAS 15K HDDs, SATA HDDs, SAS SSDs
and SATA SSDs can be mixed in each drive cage.
 512B sector HDD and 4KB sector HDD cannot be mixed.
 It is recommended to set RAID array configuration drives less than eight per disk group in order to
minimize the risk of becoming multiple hard drives failure.
 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.
 Operable ambient temperature is up to 35°C (95°F) when N8181-126 Redundant Fan Kit is installed
and any of N8150-474/-490/-477/-478/-483/-486/-513 SAS HDD is installed in the rear HDD cage.
