Hi all,
We just bought some dasd storage specifically for z/VM and for the z/Linux underneath. This is the time to decide what model to use 3/9/27… Originally I thought "the bigger the better". We are using DIRMAINT to manage dasd space and now I am not sure what is the best approach. Here are my thoughts about large models: 1. I am concerned about fragmentation. Using model-3 I could just play around with full disks not worrying about fragmentation (meaning – adding storage to a Linux guest will add a full model-3) 2. I am concerned about IOSQ time. I know z/VM supports static PAV but that is just not comfortable… We don't have Hyperpav yet… 3. Using big minidisks will make cloning difficult, (I must have the same big gaps available for cloning). Here are my thoughts about model-3: 1. Many Many device addresses… Am I missing something? The more I think about it the more I believe that model-3 is the correct answer… Can you please help me out here? Thanks, Offer Baruch. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
