Virtualization is in every one of the customers I work with daily. Unfortunately a lot of them are simply “doing it wrong”. They have fantastic virtual infrastructures with the latest hypervisors and greatest features, high availability, distributed switches, dynamic resource scheduling, and the list goes on. However, they have no way of really efficiently investigating potential bottlenecks or performance challenges. Sure if they spend a couple weeks they may figure it out, or worse they throw either virtual or physical resources at it, or even both! There must be a better way!?
There is! vRealize Operations (formerly vCenter Operations Manager) provides a simple, easy to use single pane of glass for getting visibility to how well (or not) your virtual infrastructure is performing. It can analyze and aggregate metrics based on storage, CPU, memory and network usage to provide at a glance health and issue reporting.
The health reporting is just one small aspect. Although dynamic thresholds are pretty cool, it’s the predictive forecasting and resource usage analysis that really does it for me. vRealize Operations can provide reports that indicate the amount of wasted resources in your virtual environment. Imagine that for a minute, instead of purchasing another blade or server, or purchasing another tray of disks for your SAN you can instead “right-size” your infrastructure and reclaim that waste. This is where the value and return on your investment really comes to shine. People often fail to realize that not only do over-provisioned VMs waste resources, but they can actually introduce overhead that hurts production machines.
vRealize Operations can also indicate how long until a specific resource will likely run out. For example, how fantastic would it be to know you need to purchase additional RAM in 8 months based on your consumption. This is the type of valuable data provided in this tool. It’s like having a psychic on staff!
The best part of this is that you can evaluate and test this in your environment for free. DTM has a service where we will deploy and configure vRealize as well as conduct an analysis and report to get you started. If you see what you like (which I am sure you will) then you can simply apply a license and carry on being the omniscient virtual wizard you were always destined to be.
