5: Advanced Severboard Setup
• RAID1
Disk mirroring, supports exactly two drives. The two drives represents one RAID1 logical 
drive. The operating system will be installed on the drives located in Drive 0 and 1. Note: 
Both drives must be the same type.
• RAID5
Disk striping with parity, supports a minimum of three drives and a maximum of eight 
drives. Possible configurations are 2+1, 3+1, 4+1, 5+1, 6+1 and 7+1. The operating system 
will be striped across all drives in the system. Note: all drives must be the same type
• RAID6
Disk striping with dual parity, supports a minimum of four drives and a maximum of eight 
drives. The operating system will be striped across all drives in the system. Note: all drives 
must be the same type
• RAID10
Mirrored disk striping, the data is striped across one set of drives and then mirrored on 
another set of drives. A minimum of four drives of the same type are required.The total 
number of drives must be an even number (4, 6, 8). A total of four drives is a 2+2, six drives 
is a 3+3, and eight drives is a 4+4. The operating system will be striped across all drives in 
the primary set and then mirrored on the secondary set of drives. Note: all drives must be the 
same type
PCI Card Slotting
There are three basic configurations of the SGI Rackable C2108-TY10: 
• No RAID card installed
• L8i RAID card installed
• H8iR RAID card installed
The available PCI slots for the above three configurations are as follows::
• Configuration 1: (three PCIe and 3 PCI-X slots open)
• Configurations 2 and 3: (three PCIe and 2 PCI-X slots open -slot 1 is blocked)
Note: PCI-X slot 1 is blocked when configurations 2 and 3 are used.
