Compaq RAID Array 4000 Overview 4 Hardware Technology The RA4000 consists of 11 hardware components that can be interconnected to form a Fibre Channel Arbitrated Loop (FC-AL) topology: • Compaq StorageWorks RAID Array 4000 • Compaq StorageWorks RAID Array 4000 Controller • Compaq StorageWorks RAID Array 4000 Redundant Controller2 • Compaq StorageWorks Fibre Channel Host Adapter/E • Compaq StorageWorks Fibre Channel Host Adapter/P • Compaq StorageWorks Fibre Channel Storage Hub 7 • Compaq StorageWorks Fibre Channel Storage Hub 12 • Short wave gigabit interface converters • Long wave gigabit interface converters • Multi-Mode Fibre Channel Cables • Single-Mode Fibre Channel Cables StorageWorks RAID Array 4000 This section describes the function of each hardware component and then explains the hardware architecture and Fibre Channel topology used in the RA4000. An RA4000 is an external drive enclosure containing: • A high-performance RA4000 Controller. • An optional RA4000 Redundant Controller. • A hot-pluggable fan assembly. • Optional redundant hot-pluggable power supplies. The RA4000 is available in a tower or a 4U rack form factor and supports hot-pluggable drives. The RA4000 enhances the availability of data through redundant controllers that can be deployed in an NSPOF storage system. 2 The redundant controller is an RA4000 Controller with redundancy support firmware.
