In retrospect, I believe you're correct -- which makes my original point even more important.

Help shows: usage=ppp% indicates the percentage of expanded storage or main storage in use by mindisk cache. -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Marty Zimelis Sent: Wednesday, May 24, 2006 1:59 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: z/VM 5.2 on z800 with 8G of memory Ed, One thing you'll probably want to do is cap the use of both central and expanded storage by MDC. If I read it correctly, MDC is taking nearly 800M of your V=V space (49% of 1600M according to Q MDC) for a benefit of about 1 avoided I/O per second (second line of IND LOAD).

I would like your opinions on what I am doing planning right now. We are running a MP3000 with 2gig total, no Xstore defined. One V=R, 2 V=F, and bunches of V=V machines. Paging is near zero but cpu is at 100%. ind AVGPROC-100% 01 MDC READS-000001/SEC WRITES-000001/SEC HIT RATIO-093% STORAGE-003% PAGING-0000/SEC STEAL-000% Q0-00002(00000) DORMANT-00021 Q1-00000(00000) E1-00000(00000) Q2-00000(00000) EXPAN-001 E2-00000(00000) Q3-00005(00000) EXPAN-001 E3-00000(00000) PROC 0000-100% LIMITED-00000 Ready; T=0.01/0.01 11:41:15 q mdc Minidisk cache ON for system Storage MDC min=0M max=1600M, usage=49%, bias=1.00 Xstore MDC min=0M max=0M, usage=0%, bias=1.00 Ready; T=0.01/0.01 12:01:21 We are going to a z890-160 with 8 gig. All V=R/V=F will go away. I will run those VSE machines with NOPDS, giving them the storage to match them. Total sizes for these machines will be 2799 meg (2.73 gig). So I am thinking 2 gig for xstore, 3 gig for the VSE/ESA Nopds stuff, Leaves 3 gig for z/VM. Does anyone have any other suggestion? I am really open to new and improved ideas.
