Re: Choosing between Solaris and HP-UX 11i

I have no experience with HP, but I back Sybrand's claims that Sun Hardware is not very reliable. We replaced maybe 7 CPU boards, few CPUs, one IO board, numerous disks and a few memory modules over the past 2-3 years. Sun did help us at one point to reduce the number of CPU crashes due to us having non-mirrored CPU Ecache, but tuning some kernel parameters, which reduced crashes from 3-5 times per month to maybe 1 every 2-3 (only implemented 3 months ago). WIth regards to patches, the only ones that really seemed to help, were the disk firmware patches, that seemed to help reduce a number of disks going out.

It also not always easy to find a sun support guy that cares, but they do exist.

We are considering going with high-end Intel boxes, when these will go out of service soon.
