Abstract: Compaq StorageWorks RAID Array 4000

(RA4000)
storage solutions shatter distance, connectivity, capacity, and
bandwidth limitations of small computer systems interface (SCSI)
technology. RA4000 allows highly scalable, high-performance
storage solutions for the most demanding applications. While SCSI
technology continues to satisfy the needs of many applications,
inherent input/output (I/O) and physical limitations prevent SCSI
technology from satisfying all of the expanding needs of enterprise
storage. Compaq believes that the RA4000 is the best interconnect
technology choice for future storage solutions and is committed to
delivering enterprise storage solutions based on this technology.
This paper describes Fibre Channel transmission and the cabling and
components used to assemble the RA4000 system. It also describes
how and when infrastructure cabling might be used.
If plans for a Fibre Channel storage solution include using
infrastructure cabling, a company that provides installation and
testing services can be helpful, even necessary, to determine
appropriate cabling to meet data transmission rate and distance
requirements. See Acknowledgments and References later in this
document.
Note: Not all Fibre Channel configurations require connection to
infrastructure cabling. It is common to have all system components
located near each other, eliminating the need for infrastructure
cabling. This paper includes examples of RA4000 configurations
with and without infrastructure cabling.
