Just wanted people to know that OpenBSD 3.8/amd64 runs fine on a Sun v40z, 4 x Opteron 848 2,2 GHz CPUs.
The box has 8GB of RAM, but OpenBSD can only see/use 4GB. On-board LSI1030 controller runs with integrated mirroring (I didn't know this was supported), but is very slow comparing to non-mirrored configuration. // haver dmesg: OpenBSD 3.8 (GENERIC.MP) #504:
