I was surprised to see that this unit does not have an actual battery to maintain the cache in the event of power loss. Instead it has a big capacitor which is intended to keep the circuitry powered on long enough to dump the cache to flash RAM. (Zero Maintenance Module - ZMM) This has the advantage of maintaining the cache data indefinitely instead of just a few days. It also means we don't have to continuously replace the cache batteries. Having a little trouble getting ARCCONF to work with VMware. When I installed it, I got the PSOD several times before I uninstalled it. I'm sure Adaptec support can help me.

I'm not sure what is the reason, but all 6 Series Adaptec RAID controllers fail when CIM driver is loaded. Otherwise this item works perfectly.

Despite its venerable age, the controller is still capable of providing a good level of performance and reliability. Supporting hard drives up to 12TB with firmware 5.3.0 is just superb.
