Fibre Channel RAID Controller
Each RAID Controller has two Fibre Channel host ports and two Fibre Channel
disk channel ports for a “2x2” configuration (dual host-dual drive). In dual-active
controller configurations, they can process up to 100,000 I/O’s per second
(IOPS). The dual-active pair of RAID Controllers can feed data to SAN nodes at a
sustained rate of 350 MB/sec, and process RAID 5 write operations at 270
MB/sec.
Located on the RAID Controller face plate is a 10Base-T/100Base-TX Ethernet
RJ45 connector, along with Activity and Link Status LEDs, and controller activity
LEDs.
The activity/status LEDs provide controller status information to these series of
LEDs. Below is an illustration and a table with descriptions for each LED.
Ethernet support provides for out-of-band management and storage standards
interconnect technologies such as FCIP, iFCP, and iSCSI protocols.
Software embedded on the controller provide the tools necessary to manage and
perform the configurations.
On the following page is an illustration and table which depicts and provides a
definition of each LED on the controller face plate.
