PFC 500 product description
The PFC500 is a 3.5 RU 10 drive Fibre Channel disk array with RAID drives, hot spare
drives, dual power supplies (optional), redundant controllers (optional) and spare fans –
all hot swappable. The PFC500 comes with either 36 GB (PFC536) or 73 GB drives
(PFC573).
PFC500 expansion is available using the PFC500E Expansion Chassis which houses 5
or 10 drives, but does not need a RAID controller. The PFC500’s RAID controller will
control up to 2 expansion frames (30 drives total). All PFC500 chassis must contain the
same size disk modules to make full use of the storage capacity.
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
PFC500 and PFC500E 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.
The PFC500 offers optional redundant RAID controllers for automatic failover. Failover
can occur when the primary RAID Controller, Fibre Channel Port of the Profile XP, or
Fibre Channel cable fails. When failover occurs, the system continues to run with
minimal interruption.
For servicing information on the PFC500 RAID storage system including monitoring
the front and rear panel LED indicators, and replacing serviceable modules, refer to the
PFC500 Instruction Manual.
PFR 500 product description
The PFR500 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 PFR500 currently uses 73 GB or 146 GB
drive capacities. With ten drives, one chassis holds up to 730 GB or 1.46 TB depending
on disk drive option.
The PFR500E RAID Expansion Chassis provides additional storage capacity. It is an
identical chassis with two Loop Bypass Board installed. Up to nine PFR500E RAID
Expansion Chassis can be connected to a single PFR500 comprising a single disk-array
storage system with a total of 100 drives and 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 PFR500 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
