Internal Drive Supplementary Matters

Conditions of internal drives in the default factory configuration
In the default factory configuration, there are some conditions of drive types and RAID levels that can be
installed as below.
Common

For the shipment with a RAID array, select the drives in the same capacity as many as needed.

In the default factory configuration, up to two types of Internal Drives can be installed in accordance with the following conditions
and restrictions.
Conditions for mixing Internal Drives in the default factory configuration

Up to two types of Internal Drives can be installed in the default factory configuration.

M.2 SATA SSD can be installed at the factory regardless of mixing Internal Drives.

The type of Internal Drives is classified according to form factors (2.5"/3.5"), interfaces (SAS/SATA), devices (HDD/SSD), Data
transfer speeds, and rotational speeds. The current categories are below.
3.5 inch SAS HDD, 12Gb/s, 7,200rpm

3.5 inch SATA HDD, 6Gb/s, 7,200rpm

2.5 inch SAS HDD, 12Gb/s, 10,000rpm

 2.5 inch SAS HDD, 12Gb/s, 15,000rpm
2.5 inch SAS SSD, 12Gb/s

2.5 inch SATA HDD, 6Gb/s, 7,200rpm

 2.5 inch SATA SSD, 6Gb/s
For example, 2.5 inch SATA HDD, 1TB, 7,200rpm 512n sector and 2.5 inch SATA HDD, 2TB, 7,200rpm 512n sector are
regarded as the same type of Internal Drives.
Common restrictions of mixing Internal Drives in the default factory
configuration

Internal Drives with a different sector size cannot be mixed, even if they are the same type.
For example, a mixing of 2.5 inch SATA HDD, 1TB, 7,200rpm 512n sector and 2.5 inch SATA HDD, 2TB, 7,200rpm 512e sector is
NOT supported in the default factory configuration.

SSDs of different Endurance (ME, VE, RI) cannot be mixed, even if they are the same type.
For example, a mixing of 2.5 inch SATA SSD, 400GB, 6Gb/s VE (Value Endurance) and 2.5 inch SATA HDD, 800GB, 6Gb/s RI
(Read Intensive) is NOT supported in the default factory configuration.
Mounting order of mixing Internal Drives in the default factory
configuration

In the default factory configuration, the drive mounting order is defined as below.

The Internal drives is installed in the order of Front Cage, Middle Cage, Rear Cage.
Order
1 2.5 inch SAS HDD
2 2.5 inch SAS SSD
3 2.5 inch SATA HDD
4 2.5 inch SATA SSD

The Internal drives are installed in the ascending order of a slot number, when the same type of the drives are selected, the drives
are installed according to the order below.
