I was about to head to bed till I saw this really funny VMware video on my facebook. I thought it was too funny to pass by it and not share it with my readers. Check out how the Cavemen want efficiency too! Move beyond traditional IT management solutions with VMware. Don’t miss this video and watch it and have a great laugh.
VMware vCenter ChargeBack was released on Nov 30, 2011. It has quite few awaited enhancement and a bit of interface polishing. For those of you who did not hear of VMware vCenter Chargeback Manager or does not know why its required, I will brief you a bit before going into the details of the new releases. If you have been in the virtualization field for a while, then for sure you have heard of the VMs Sprawl(A large amount of virtual machines on your network without the proper IT management or control) or Zombie VMs(VMs that are using resources but their role is no longer required). For more info about Zombie VMs, you might want to check out my earlier post at: Zombie VMs.
As lately I have been testing several of our Enterprise Management Solutions, & I have been sharing them more often with our customers. After the announcement of vRAM, vCenter CapacityIQ is one of the products that seems to grab attention quickly. After delivering several POCs to customers, most of them have came back to me and asked me on the procedure to Grant a User Access to vCenter CapacityIQ. Most of them want to ensure that they can create a user name & password for their monitoring team that does not have access to anything else in vCenter. As the steps are not too clear in our documentation, I have decided to share it on here with few snapshots:
Capacity Management importance has been on the rise since Virtualization started becoming a main stream. In earlier days in the physical world, Capacity Planning/Management used to end at the time the hardware was purchased. In most cases, the hardware was over-sized to ensure it can handle the workload as well future growth of the application. Though as that over-sized box is dedicated to a single application, it did not matter how you sized that application as long the server has enough resources to run it. Though when virtualizing the story is fundamentally different, as now you have multiple VMs per server. If VMs are over-sized that means your consolidation ratio & other VMs performance can be affected. If Virtual machines are under-sized, then they will not perform well. Idle & unused VMs can be of a huge waste of expensive storage and need to be avoided.
Most organization today has different complains about their current performance monitoring tools. These problems are put under the magnifier when Virtualization or Private Cloud is implemented. Below are few of the main complains getting heard & VMware is trying to respond to by vCenter Operations Manager:
