Re: How much memory?
Guys, Thanks for all your help. Unfortunately management (at MD level) have shot this idea down. Sometimes, I wonder if there is any commitment at all for the mainframe platform
How much memory?
Hi all, I'm not a VM expert, so forgive me if this seems a newbie quetion. I have a z800 running z/VM, which has two production z/OS guests, and the usual collection of CMS guests (TCPIP / OPERATOR etc). We discovered recently that the z800 has an IFL (long story - don't ask!) and would like to steal some of the 8GB currently allocated to VM, to run up a VM / Linux LPAR for a POC. The two z/OS guests are defined at 256MB 512MB (Bill Gates, are you watching??), and don't page. In your most esteemed opinion, what could I steal from the VM LPAR withou t hurting it's and the guests performance / making it page? Personally, I think 2GB would be enough. Comments and opinions welcome.
Re: What speed are my channels actually running at?
Great, That's what I hoped. Thanks.
What speed are my channels actually running at?
Hi all, I've just been making a Visio diagram of out I/O config on some old hardware (z800), which runs two z/OS guests under VM (5.4) I dicovered that, although the VM IOCP has channels to my DASD system as FC (FICON) the z/OS IOCP has them defined as CNC (ESCON). So what speed am I going to get on a z/OS I/O, ESCON or FICON? I'm assuming VM does something clever, like ignore what z/OS says? TIA
