K2 Level 2 RAID storage description
The K2 Level 2 RAID Storage is used in Level 2 and Level 2R K2 Storage Systems.
The RAID storage device is a high performance, high availability mass storage
system. The L2 RAID chassis 2Gb/s host interface supports industry standard Fibre
Channel technology.
The L2 RAID chassis utilizes dual FC-AL technology, allowing two loop
configurations within a single chassis. Port-BypassCircuits 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 hot swappable modules. 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.
The L2 RAID chassis contains 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.
