redundant modules. This improves serviceability and increases fault tolerance by
eliminating any single point of failure. With two RAID Controllers, the two loops
within a single standard chassis are configured as a single loop with a backup loop in
standby mode.
PFR 600 features
The PFR600 controllers provide enhanced performance of up to 2 Gb/s transfer rates
using SCSI protocol. Interchangeable SFPs (Small Form-factor Pluggable) adapters
allow you to configure your PFR600 for operation in a copper or fiber-optic (optical)
cabling environment. Generally, use optical SFPs and cables, which are rated at
2Gb/s, wherever possible, such as to connect a PFR600 to a Profile XP Media
Platform equipped with a Fibre Channel Disk II card, or to a Fibre Channel switch in
an Open SAN installation. Use copper SFPs and cables, which are rated at 1 Gb/s, to
connect a PFR600 directly to an older Profile XP Media Platform that does not
contain a Fibre Channel Disk II card.
The PFR600 supports up to four PFR600E RAID Expansion Chassis. It does not
support connection to PFR500E RAID Expansion Chassis. Always use optical SFPs
and cables to connect the PFR600 to PFR600E RAID Expansion Chassis to ensure
optimal performance of your RAID storage system.
Capacity and redundancy
The PFR600 Series contains five or ten half-height 3.5" Fibre Channel Arbitrated
Loop (FC-AL) disk drives. The chassis also supports one or two hardware RAID
Controllers in one 3U high rack-mountable chassis. The PFR600 Series currently uses
36GB, 73GB or 146GB drive capacities. With ten drives, one chassis holds up to
360GB, 730GB or 1.46TB depending on the disk drive option.
The RAID Expansion Chassis provides additional storage capacity. It is an identical
chassis with two Loop Bypass Board installed. Up to four RAID Expansion Chassis
can be connected to a single PFR600 Series comprising a single disk-array storage
system with a total of 60 drives and 2.16TB, 4.38TB or 8.88TB of storage depending
on the disk drive option. The built-in chassis daisy-chaining capabilities provide for
cost effective storage expansion as requirements grow.
