here are some tests i ran when testing my cluster
all 32bit dom0/domU, centos5.1 xen 3.0 drbd 8.0.11
disks are sata
Vendor: ATA Model: Hitachi HUA72105 Rev: GK6O
drbd is synced via gigabit crossover cable on a pair of BCM5721
hopefully this formats well ;)

To sto si frustriran, zavidan tko zna na cemu i sto ne vidis dalje od
svoje guzice je tuzno. Da onda barem imas toliko samokontrole da
sutis umjesto da pravis budalu od sebe... izgleda da si prestar da se
promjenis na bolje. - Davor Pasaric, hr.comp.mac
