CONFIGURATION GUIDE – NEC Express5800/R120g-2E
NEC Corporation Revision 7.0 – August, 2017 16
4 Internal Hard Disk Drives
4.1 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 4.2.3 for the required components and then refer to the section 4.3.4
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.
