Art, Thanks for the links on NUMA. I'll have to read up on that. Your point about not sharing with Windows VMs causes me concern, as there are many more Windows VMs than Linux VMs in this shop. And given that they are touting the ability of SimpliVity to migrate VMs as it sees fit (for load balancing? ...

Art, Not sure about "same frame" vs. "same host" vs. "same node". There are multiple terms that seem to be saying the same, or nearly the same thing. But yes, my understanding is that there are multiple virtual machines running on one physical machine. That is seen as a major source of efficiency ...

If there are ...

Paul, You mention "passed all the DR tests." That is something I've been trying to work out in my head - how to test this for DR. In most cases, you can't "crash" a VM. You can issue a command to stop it, but as part of stopping it, it will go through a controlled series of steps, at least at the ...

Hello All, I've been working with Informix for a number of years, but always on physical servers. We now are migrating to virtual servers running under VMWare/SimpliVity. As part of this, we will be upgrading our Informix from 11.70 to 14.10, and from RH 7.x to 8.2. I understand the basics of server ...
