Unless you’ve been living under a rock or aren’t in the IT field at all, by now you’ve likely heard about the widespread Spectre and Meltdown vulnerabilities affecting an enormous swath of processors manufactured by Intel and AMD, the industry leaders, leading to security vulnerabilities and performance problems.
Green House Data staff have been hard at work patching systems as fixes have come available this week. Here’s a quick summary of the vulnerabilities, their effects on cloud and general computing performance, and what we’ve done to fix them so far. We also provide a few links for users who need to patch their own operating systems or investigate further.
It’s easy to provision additional VMs and increase resource commitment from your overall resource pool using the vSphere web portal. Maybe too easy. If you overstretch your resources, some features like High Availability failover may not function as planned. HA keeps your VMs from failing by pooling VMs and hosts in a cluster, relaunching failed VMs on alternate hosts.
Overcommitting resources can also lead to general performance problems, so it is in your best interest to use Admission Control to keep a close watch on overall capacity. Another reason? You might be trying to power on new VMs, only to run into errors as you exceed your Admission Control rules. Tweaking them can save you from buying additional host resources.
This post will introduce the concepts of slot sizes and configuration of Admission Control to allow more VMs to move between hosts when you have turned on High Availability in vSphere/vCenter.
