Re: Linux for z - how many LQ users?
We've been running Suse for 3-4 years in production, mostly for portal-type applications like DB2 Connect, etc. Although we haven't put much in the way of demand on it, Suse under z/VM has been a very stable platform.
Now that we have a z10 (and the facilities folks are reporting power consumed by group), the distributed group is showing some interest in migrating. They're Red Hat oriented, however, and we may have to switch distros.
Pricing seems to be another attraction factor although I'm fuzzy on the numbers there. Good luck getting something going. It's been a long road at my company.
