Thank you guys for pointing me to zEDC. That's indeed what I was looking for. We have the zEC12 but I was told we don't have the zEDC card :( Thanks!

Re: Advice on doing RHEL 7 LPAR install
Actually, I did do a VM install to get a running RHEL 7 system they could play with. However, the project they are working on involves adapting software that currently runs in an appliance to be installed into an LPAR. Its been tough because these guys have next to no Linux skills at all. So, besides giving them a running RHEL 7 system to play with, myself and a colleague have been trying to educate them on how LPARs and HMCs work in general. Ultimately, they are going to need to develop their own installer that won't have to depend on an outside source for Linux. But, since they don't understand how to do a traditional install, we were starting with that. I think the light is finallying beginning to dawn on them that a z doesn't work like an Intel pizza box. sigh... Well, at least I have learned more about RHEL than I knew before. Just wish I didn't have so many other projects going on that this is delaying.

Not sure > when Red Hat included it, but it was probably RHEL 7.0. Working on getting this into RHEL 7.x. Source-code-wise, it is the same PCI device driver (not s390x-specific). The latest IBM Java code provides support through the java.util.zip classes (use the constructor to set larger buffer sizes like 64k or 256k to get best performance; specifically decompression does not improve otherwise). Please refer to http://www-01.ibm.com/support/knowledgecenter/SSYKE2_7.0.0/com.ibm.java.lnx.70.doc/user/power_compression.html?lang=en for Java documentation and minimum SR level. Experimental user space code is at https://github.com/ibm-genwqe/genwqe-user , if you are willing to spend time playing with it.

You might want to have a look at kiwi (which is available with SLES). This gives you the possibility to actually build appliances not only for SLES, but also for RHEL. It is possible to build appliances for both, zFCP and DASD. You only have to dump the image to disk and bootup. At SUSE, we even have our build service worker appliance (the system that really builds packages on mainframe) setup as kiwi appliance that is deployed on LPAR by just doing a load via snipl. I have done a live presentation once that did an introduction, building a wordpress appliance, and deployment to LPAR within 45 minutes...
