Adaptec 3805 – It’s rubbish

An update on my previous posting about the Adaptec 3805 and my troubles with getting compatible drives.

I’ve been running a RAID-5 with the 3085 using 4 Samsung SpinPoint F3’s for about 2 weeks, and two days ago it started to give problems. The fourth disk in the array just dropped out, with no visible SMART issues or physical defects.

So, after waking up to this news I added it back into the array (probably not a great idea, but usually its fine). The moment the full initialization completed, something occurred that caused one of my Virtual Machines running from that RAID array to stop functioning (it was a mail server). There was another machine on there with much lesser activity, that kept running without a problem – but it did all but destroy the other virtual machine. Luckily, i have backups.

Not only did it knock off one of my virtual machines, it kicked out a different disk from the array, and started complaining again. So then I broke down, and ordered 2 ES.2 disks from Newegg which are on the HCL for this controller. However, 8hrs later, the controller barfed up completely and started giving timeouts to the host to the logical drive – even with 3 perfectly useable drives. The host became very unstable, i had to shut down the virtual machines, and reset the machine (thank god for Lights out control).

Upon reboot, the logical raid-5 array was unusable, and had to be forced online. I copied the two files that i absolutely had to have, and finally destroyed the array. When i go up to the data center again, I’m removing this card and burying it. Going to go back to my trusty Highpoint RR2224 which I’ve had for over 5 years now, without a single glitch.
