Drives
Drives in SpycerNode SC are protected by RAID 6. RAID 6 uses two parity
stripes to distribute data across the set of drives. It allows for two disk fail-
ures within the RAID set before any data is lost. All drives provide error
detection and correction capabilities. These are reported to the application in
line with the SCSI specifications.
Carriers
Drive carriers are used to hold the storage disks. A drive carrier houses a
single 3.5 SAS drive or, with an adapter, a 2.5 inch SAS SSD.

Disks Layout
The drives are divided into two drives sets (01 - 30 and 31 - 60) for a total of
60 drives. A system with half capacity will have only the first set populated.
The layout of the drive sets is as follows:
At shipment, the hard disks are delivered separately and therefore have to be
installed before putting the system into operation, see also "Installing the
Drives" (page 36).
