Subject: zenloadbalancer port to Linux on Mainframe S390 platform under z/VM

** **

First of all Zenloadbalancer is a wonderful product, nicely implemented
using already existing tools like pen, pound, mini_httpd, ucarp,
check_http, rsync etc. Nicely written lightweight GUI. Running with RAM
usage of 70MB-impressive!  I am very pleased with its reliability, I have
just tested it until now for TCP loadbalancing, it’s not in production yet.*
***

** **

I wish I could keep it running in VMware environment but we need to run it
in our mainframe Linux (zLinux under z/VM) –we use Novell’s SLES (SuSE
Linux Enterprise Server). ****

** **

So my question would be- how could this be ported to s390 platform? Since
this is opensource and each of the tools can support s390 linux, how could
I run it on my small little SLES  instance  in the mainframe. Most of the
code is written in Perl. But there are some binaries too.(see ELF binaries
below). Are there any procedures I could follow to do this myself if
possible?****

** **

Also, any reason why the virtual appliance is based on 32 bit version and
the physical one is instead 64bit.-we use only 64 bit Linux on our
mainframe.****

** **

My wish list:****

1) Port to other Linux platform like S390(mainframe)-CentOS/RHEL etc****

2) command line support /documentation for regular LB activities etc
(because the GUI is a little slow-its works perfectly fine, please don’t
get me wrong)****

3) some documentation/specifications listing requirement for sizing
purposes listing traffic/data/CPU/memory/workload sizing limits etc.****
