I am not sure if it was on Dell or HP machine - controller presents first disk only in the boot time so I created small (10 - 15GB partition) on each disk and use them all in 4 way mirror. Cannot say if it was gmirror with UFS or ZFS mirroring. The rest of the each disk was used for ZFS RAIDZ. > ( Having to use Windows XP to talk to the iLo due to browsers dropping > support for the old ciphers doesnt help either, what do other people > with oldish HP hardware do about this ? I know its off topic, but theres > a lot of it out there... ) I have WinXP guest in VirtualBox exactly for this situation. With old browser, with old Java, with Flash - believe it or not, Cisco UCS C200 has remote management created in Flash! Miroslav Lachman
