4 - Verifying Installation
Once the Rocket RAID 2220 host adapter and hard disks have been installed into the chassis, boot-up the
system to verify that the hardware is properly recognized.
1. Power on the system. If the system detects the presence of the adapter, the RocketRAID 2220 BIOS
will be displayed.
2. Press Ctrl+H to access the RocketRAID 2220 BIOS Utility.
The BIOS Utility will display information about hard disks attached to the adapter. Make sure all attached
disks are detected by this utility. If any of the hard disks are not detected, power down the system and
check the power and SATA cable connections.
5 - Single-RAID Cross Adapter
The RocketRAID 2220 is capable of supporting RAID arrays created between hard disks attached to
multiple host adapters. Up to sixteen hard disks can be assigned to a single RAID array, and these disks
can be attached to as many as four separate RocketRAID 2220 host adapters. This feature is referred to as
“Single-RAID Cross Adapter” support.
Each RocketRAID 2220 provides two jumpers dedicated to this feature (JP1 and JP2), and a single cross-
adapter cable designed for use with these jumpers. JP1 is a 3-pin jumper, while JP2 is a 4-pin design.
Each cross-adapter cable has a 3-pin and 4-pin connector, designed for insertion into JP1 and JP2
respectively.
Example installation:
For a 16-hard disk, 2-card cross-adapter RAID configuration, install a second card into the next available
PCI-X slot. Insert one end of the cross-adapter cable into the appropriate jumper on the first adapter (3-pin
connector to JP1, 4-pin connector to JP2), and the remaining connector into the appropriate jumper on the
second adapter. There is no particular connector-to-jumper requirement. Any given connector can be
inserted into the corresponding jumper on either card.
