Internal drive supplementary matters
Conditions of Internal Drives in the default factory configuration
In BTO configuration, there are some conditions of drive types and RAID levels can be installed as below.
Common

All drives in BTO shipment should be of the same type, sector and rotation speed.

For the shipment with RAID array, arrange the drives in the same capacity as many as needed.
RAID controller configuration

RAID level 0, 1, 5, 6, 10 can be installed for BTO shipment. Selectable RAID levels are depending on the RAID controller.

Capacity of Logical drive can be within 2TB with legacy boot mode, capacity of logical drive can be within the total capacity of
logical disks with UEFI boot mode.

As factory shipment, Initial cache policy of RAID controllers is Write Through for N8103-192, Write back for N8103-193.

Conditions for mixing of Internal Drives after shipment

RAID controller is required for mixing of Internal Drives

Mixed Internal Drives cannot be installed in the same RAID array.

When using hotspare disk for different RAID arrays which consist of various type of drives, assign “Dedicated Hot Spare” to
each RAID arrays with the same type of drive, to prevent from mixing different type of drives in a RAID array. “Global Hot Spare”
cannot be used.
Mixing of different type of drives
Two types of drive can be installed in standard drive cage (4slots) and optional drive cage (2slots). Same type between different
drive cages is not necessary.
