The meaning of each element of the BC4000 Series controller model number is illustrated in
Table 1
.
Current models are Serial ATA and support up to RAID50. This means the only variable model number
elements are the functionality level and the number of channels. The third and fourth numerals in the RAIDCore
controller model number reflect the functionality level that is licensed. The controller has three functionality
levels: level 52
, level 50 and level 10.
The RAIDCore BC4000 Series RAID controllers support either four or eight storage channels. As shown in
Table 1
, the second numeral indicates the number of channels on the controller. For example, the BC4450-02
is a 4-channel controller that supports level 50 features, and the BC4852-02 is an 8-channel controller that
supports level 52 features.
