Compaq RAID Array 4000
Storage System: Deployment
and Configuration
Abstract: As the performance of processors and peripherals
improves and companies increasingly move to distributed
architectures while consolidating servers, the company's
administrators generate high-speed and data intensive network
applications. As a result, interconnects between servers and the I/O
devices they support have become a management bottleneck.
Fibre Channel storage solutions shatter distance, connectivity,
capacity, and bandwidth limitations of SCSI. Fibre Channel allows
highly scalable, high-performance storage solutions for the most
demanding applications. Compaq believes Fibre Channel is the best
interconnect technology choice for future storage solutions and has
developed the RAID Array 4000 (RA4000) Storage System, which is
based on this technology.
This paper describes how to:
S
Upgrade an existing single controller Fibre Channel Storage
System to the dual controller RA4000
S
Install an RA4000 with either single or dual controllers
S
Deploy full redundancy with either a Fibre Channel Storage
System or an RA4000
