I've lately been using the MegaRAID cards DELL ships in it's 2800's and 2850's. We're using the PCI-E riser, which equates to the 320-2e. You can purchase a version of this adapter built into the riser, and you can purchase the adapter as an expansion card. We're a little concerned about the expansion card because under load, as it continually throws battery fast recharging and battery temperature out-of-range errors. The adapter built into the riser doesn't do this. I think this may be related to the case design, which doesn't seem to provide very good air circulation to the expansion cards. For comparison, we also purchased an Adaptec 39320A. The LSI cards are more configurable. In our early testing, the Linux drivers for the Adaptec weren't up to snuff. I think the drivers have been improved since, but we were past our decision point by then. If anyone has a MegaRAID 320-2e in production which you're monitoring w/ megamon, I'd love to know if you're getting any error reports. Those two cards seem to be it for the internal Ultra320 RAID market. I wouldn't say either of them 'suck', as you say, but I wouldn't give either one an A+ either. I'd like to spend more time w/ the Adaptec now that the drivers seem to have been fixed, but haven't found the time... -- Ron Peterson Network & Systems Manager Mount Holyoke College http://www.mtholyoke.edu/~rpeterso -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
