RAID Configuration
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 4.2.2 for the
required components and then refer to the section 4.3.2 for the hard drives.

NOTE:
Up to four hard drives can be installed in the Embedded SATA configuration.
All drives within a RAID array should be of the same type, capacity and rotation speed.
Up to two kinds of drives selected from SAS 10K HDDs (512n), SAS 10K HDDs (512e), SAS 15K
HDDs, SATA HDDs, SAS SSDs, SATA SSDs (ME) and SATA SSDs (VE) can be mixed in each drive
cage.
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.
