The Scale model uses an DX100 S3 storage array with large capacity, highly cost effective
Nearline SAS disks (Serial Attached SCSI). Twelve disks of 3.5'' size with a capacity of 4TB
each and a speed of 7,200 rpm are implemented to each module of the storage array. Always
six disks are building up a RAID 6 (4+2) disk group, i.e. there are two RAID 6 groups in each
storage module. In addition, sixteen SAS disks of size 2.5" with a capacity of 900GB each
and a speed of 10,000 rpm are implemented in the server. Two disks are reserved as hot
spare, the other ones are used by the operating system and to store the backup metadata.
