s390 repositories for RHEL
Hello list, I need a few packages that is not included in RHEL. First and foremost Puppet and dependencies which is at least ruby-rpm and ruby-shadow if I remember correctly. I have not found any s390 packages in the well known repositories like EPEL, rpmforge or dag. Do you know any repositories that contain s390 binary packages for RHEL? I could build them myself from the EPEL srpms, but if binary packages (from a reasonable source) exists I prefer to use that.

There are some people running things like file servers, simple web servers, etc., but in the majority of cases, management has gone for the big return on investment by putting up big applications. No surprise, but these are the workloads that save the most money, even when compared to virtualization on midrange hardware. First, thanks for your informative reply. One argument against linux on z/VM I have heard a lot is that memory on a mainframe is expensive compared to memory for vmWare ESX-hosts. Do you know any rough estimates for how much physical memory that is needed for each linux host on z/VM that is running WAS? I know z/VM implements various techniques to reduce overall physical memory requirements among a set of hosts, but how effective is it?

Advice on zLinux for a systems-administrator from the x86 world
Hello list, I work as a Linux systems administrator. Currently we have about 200 virtual (vmWare) and 40 physical linux servers. Most of these servers are used for WAS (Websphere appserver), a few for WPS (Websphere process server), and a few for other uses. My employer is condidering zLinux (on a z10 BC mainframe). I have no experience with mainframe, z/VM or zLinux. Can you describe how you use zLinux? What kind of software do you run on zLinux? how many zLinux instances per IFL, how much memory? What kind of workloads do you think realizes most economic benefits on zLinux? If you are familiar with other virtualization alternatives, can you compare zLinux on zVM with them? (for instance cost, performance, simplicity of administration, etc).
