PFR 700 product description
The PFR 700 Series contains five, ten, or fifteen 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 PFR 700 Series currently
uses 36GB, 73GB or 146GB drive capacities. With 15 drives, one chassis holds up to
540GB, 1.095TB. or 2.19TB depending on the disk drive option. Drives are numbered
0 to 14 in the PFR700 RAID Chassis.
The PFR 700E RAID Expansion Chassis provides additional storage capacity. One PFR
700E RAID Expansion Chassis can be connected to a single PFR 700 comprising a
single disk-array storage system with a total of 30 drives and 1.08TB, 2.19TB, or 4.38TB
of storage depending on the disk drive option. This provides for cost effective storage
expansion as requirements grow. Drives are numbered 16 to 30 in the PFR 700E RAID
Expansion Chassis. There is no drive 15 between the PFR700 RAID Chassis and the
PFR 700E RAID Expansion Chassis.
The PFR700 utilizes dual FC-AL technology, allowing two loop configurations within
a single chassis. Loop integrity is maintained during failures without user intervention.
Each loop and associated circuits along 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.
The PFR700 controllers provide enhanced performance of up to 2 Gb/s transfer rates
using SCSI protocol. Optical cables connect to hosts, such as 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. Copper cables connect a PFR700 to the PFR700E RAID
Expansion Chassis
NOTE: Grass Valley does not support mixing disk drives of differing capacities in
any RAID chassis. For example, if a PFR700 and PFR700E 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.
Refer to the PFR700 Instruction Manual for service information, including monitoring
the front and rear panel LED status indicators, and replacing serviceable modules.
