with all other active components are on redundant, separate hot swappable 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.
PFR500 host interface supports both Arbitrated Loop and fabric switching industry
standard Fibre Channel technology. The physical layer is determined by the use of
GBICs.
NOTE: Grass Valley does not support mixing disk drives of differing capacities in
any RAID chassis connected to a Profile XP media platform. For example, if a
PFR500 and PFR500E are connected to a Profile XP system, all the disk drives in
both chassis must be of the same capacity. If a qualified drive of a different capacity
is added, all the drives in the chassis will take on the characteristics of the smallest
drive.
For servicing information on the PFR500 RAID storage system including monitoring
the front and rear panel LED indicators, and replacing serviceable modules, refer to the
PFR500 Instruction Manual.
PFR 600 product description
The PFR600 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 currently uses 36 GB, 73 GB or
146 GB drive capacities. With ten drives, one chassis holds up to 360 GB, 730 GB or
1.46 TB depending on disk drive option.
The PFR600E RAID Expansion Chassis provides additional storage capacity. It is an
identical chassis with two Loop Bypass Board installed. Up to five PFR600E RAID
Expansion Chassis can be connected to a single PFR600 comprising a single disk-array
storage system with a total of 60 drives and 3.6 TB, 7.3 TB or 14.6 TB of storage
depending on disk drive option. The built-in chassis daisy-chaining capabilities provide
for cost effective storage expansion as requirements grow.
The PFR600 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 Bypass Circuits along
with all other active components are on redundant, separate 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.
PFR600 host interface supports 1Gb or 2Gb Fibre Channel physical layers. The physical
layer is determined by the type of Small Form-Factor Pluggable transceiver (SFP)
installed in the host port. 2Gb operation requires the optical SFP. Copper SFPs are used
for 1Gb operation.
NOTE: Grass Valley does not support mixing disk drives of differing capacities in
any RAID chassis. For example, if a PFR600 and PFR600E are connected to a
Profile XP system, all the disk drives in both chassis must be of the same capacity.
If a qualified drive of a different capacity is added, all the drives in the chassis will
take on the characteristics of the smallest drive.
