PFR500/E features
The PFR 500 Fibre Channel RAID Storage Chassis is a high performance, high
availability mass storage system. High-bandwidth storage is made possible using
Fibre Channel Arbitrated Loop (FC-AL) technology. The PFR500’s modular,
scalable design provides additional disk storage as your needs increase.
Feature highlights:
• Ten drives in a 3U vertical rack space
• No single point of failure
• All active components are hot-serviceable
• Scalable expansion using PFR500E RAID Expansion Chassis
• Optional dual RAID controllers provide Fibre Channel failover
• Copper Fibre Channel interface (GBIC)
The PFR 500 utilizes dual FC-AL technology, allowing two loop configurations
within a single chassis. Port-Bypass Circuits have been added to maintain loop
integrity during failures without user intervention. Each loop and associated Port
