Compaq RAID Array 4000
Overview
Abstract:
The Compaq StorageWorks RAID Array 4000 (RA4000),
formerly the Fibre Channel Storage System, is an external storage
solution incorporating Fibre Channel interconnect technology. This
solution overcomes inherent limitations of small computer systems
interface (SCSI) interconnect technology. Fibre Channel interconnect
technology is designed to satisfy the requirements of such enterprise
applications as databases, data marts, email, groupware, Web
servers, and file and print for large storage capacity and scalable
input/output (I/O) performance.
The architecture of this Fibre Channel storage solution enables
administrators to simultaneously achieve multiple goals:
•
To provide hardware redundancy and failover capabilities with
no single point of failure (NSPOF).
•
To build a scalable external storage solution for high capacity or
high growth applications by:
•
Scaling a single I/O slot to more than 3.2 TB.
•
Scaling an 8-PCI-slot server to more than 25.6 TB.
•
To scale cache and processing power for increased I/O
performance.
•
To conserve I/O slots for connecting other types of I/O devices.
This technology brief explains the hardware components, hardware
architecture, firmware functionality, software support, and
performance expectations for the RA4000.
