Re: HP's inability to move off Itanic ...
"Erm... where? Not seen any, and the other sysadmin and architect people I know don't seem to have come across it either."
There are some parts of Earth outside UK, I think that's the reason.
"Ah, immediate troll exposure! You have obviously never touched clustering on Linux. Go look at RHEL, it's clustering has been excellent for years."
I'm working with linux and unix servers as oracle db admin for 15 years. RHEL clustering is very far from being excellent. Its functionality is pretty basic. Majority of RHEL clusters I've seen had HP Serviceguard installed instead, even if this is also far from perfect. I'm afraid you have no clue how clustering in Solaris works and how far and how nice it is integrated with oracle, since Sun years. There's no other solution on a market like this. Ask any oracle dba.
"You really are just exposing your lack of knowledge. KVM has been around for years and is an enterprise-level product, let alone good old Xen. The virtualisation in hp-ux is good in width (more ways to virtualise), but I'd have to say Integrity Virtual Machines is no better than KVM. And as for hp's clustering, Serviceguard has been available for Linux for years, it just lags the hp-ux version"
Now go and read oracle rdbms license and especially pricing part, in terms of different hypervisors used. Then we can discuss, cause now it really doesn't make sense as you have no clue.
