- Actual power consumption 42
- All power is supplied to the adapter via the pci express 3 v and 12v rail necessary voltages are provided by onboard switching regulator circuitry operating off of 12v and 3 v rails 42
- Electrical characteristics 42
- Note 12v is used in the charging circuitry for the battery pack on the optional bbu remote card if the bbu remote card is cable connected the following power consumption figures apply 1 during trickle charging of the battery pack n a no trickle charge for li ion 2 during fast charging of the battery pack 250ma rise in 12v current 42
- State 1 during bbu fast charge 42
- State 2 during initialization of all raid 5 logical drives simultaneously 42
- State 3 while sitting idle at the dos prompt 42
- Supply voltage 12v 8 from pci edge connector only 42
- Supply voltage 3 v 9 from pci edge connector only 42
- Table 10 actual power consumption table 42
- The following states determine the typical current consumption of the board 42

- One or more arrays are associated and given a raid level this process creates a virtual drive and provides an option to initialize the virtual drive 44
- One or more physical drives are selected and associated as an array 44
- Raid firmware is based on the concept of associating physical drives in arrays and then creating a virtual drive from that array that includes a functional raid level to create a virtual drive and present it to the host operating system the raid firmware typically follows these steps 44
- Raid functionality and features 44
