in z10 one IFL idle load for an 'empty' sles10: about 0:2 % with monitoring(Tivoli) and WAS: at least the double
With a mixed environment, WAS,DB2connect,IMS SoapGW, infraservices, cvs,subversion test qa and prod about 90 Linux per IFL at 80% cpuload. Varies great of course, depending on lot's of things. For example more customers normally means more servers with fewer apps one customer with more apps in same server = more cost-effetive and fewer servers Cordialement / Vriendelijke Groeten / Best Regards / Med Vänliga Hälsningar Tore Agblad Volvo Information Technology Infrastructure Mainframe Design & Development SE-405 08, Gothenburg Sweden E-mail: [email protected] http://www.volvo.com/volvoit/global/en-gb/ ________________________________________ From: Linux on 390 Port [[email protected]] On Behalf Of Bernie VK2KAD [[email protected]] Sent: Thursday, June 18, 2009 06:38 To: [email protected] Subject: FW: Rules of Thumb Hi all Has anyone developed any "rules of thumb" for zLinux based on practical experiences?? As a newbie, I am interested in trying to establish just how many guests one can fit into a Series Z CPU or IFL be it z9 or z10. Wild statements about 1000s of virtual guests being fired up may excite the marketing types but setting out to architect a new environment can be daunting. I am very much aware that very much 'it depends' on the application and workload mix but until you get some real hands-on, it is difficult to get a business proposition together to invest in significant upgrades to existing hardware just to find out that the workload just doesn't 'fit'. For example, I know that Cognos for example is capable of running on zLinux - but when I look at it's workload profile on existing mid-range hardware if appears that it wouldn't be a very sociable guest. From practically idle to 100% busy for 1-2 hours or more says this guy doesn't like to share his toys and thus wouldn't be a very good candidate - or am I wrong?? The theory of resource sharing is pretty well understood - what I am looking for is real world experiences that hardened zLinux'ers are prepared to share with the entry level community. Can anyone help me here.
