using the new assigned IP addresses.
Note: To manage storage subsystems through a firewall, configure the firewall to
open port 2463 to TCP data.
Controller memory
Each RAID controller has data cache memory. The processor memory stores the
controller firmware, while the data cache is a buffer used to temporarily store hard
disk drive data during data read and write operations. A Cache Active LED on the
controller turns on when the cache contains data that has not been written to hard
disk drives. The Cache Active LED turns off when the cache does not contain
unwritten data.
Table 6 lists the technical specifications for the RAID controllers.
