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 11) for configuration
to 4.2.6.

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
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.

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
N8150-541/-483/-486/-518 SAS HDD is installed in the rear HDD cage.
