The LSI Logic MegaRAID 320 storage adapters are high-performance
intelligent Peripheral Component Interconnect to Small Computer
System Interface (PCI-to-SCSI) host adapters with Redundant Array of
Independent Disks (RAID) control capabilities. MegaRAID 320 storage
adapters provide reliability, high performance, and fault-tolerant disk
subsystem management. They are an ideal RAID solution for the internal
storage of workgroup, departmental, and enterprise systems.
MegaRAID 320 storage adapters offer a cost-effective way to implement
RAID in a server.
MegaRAID 320 storage adapters are available with one, two, or four
SCSI channels.
The MegaRAID 320-1 storage adapter (single-channel) has one
LSI53C1020 controller chip that controls one SCSI channel. The
storage adapter has one very high-density cable interconnect
(VHDCI) 68-pin external SCSI connector and one high-density cable
interconnect (HDCI) 68-pin internal SCSI connector.
The MegaRAID 320-2 storage adapter (dual-channel) has one
LSI53C1030 controller chip that controls two SCSI channels. The
