Capacity planning and provisioning in a modern virtualized data center

I remember those junior school days when we learned about the unitary method in mathematics to solve a class of problems in variation. We started by solving problems with only one parameter varying, e.g., if 2 boxes contain 12 eggs, how many eggs would 5 such boxes contain?


The complexity of these variations increased with time and with advanced mathematics. And now, if I am a vSME (virtualization Subject Matter Expert) in an IT department, I am swamped with a large number of requests to solve problems with far more variations and constrains. Some of these include:

  • Different business units giving me their individual projected capacity requirements from the virtualized data center at different points of times
  • My colleagues asking me to analyze the impact on the data center as some hosts need to be taken down for maintenance
  • My boss needing to know if I have sufficient capacity to handle all the additional requirements because of the business expansion plans

And when I am staring at a shortfall in capacity, I need to figure out how to augment the capacity. (Sigh…. wasn’t junior school easier? !!)


Thanks to modern tools, this work of capacity planning and provisioning is getting simpler every day. When I think of capacity planning tools, my request is that the tool fits into my way of working, rather than me fitting into the tool. I should be able to input all of the capacity requests and maintenance downtimes as they currently are into the system. The system should tell me if I can manage that with my current capacity, or if I have a shortfall. Tools like HP vPV allow me to do just that.


But it is not good enough to only know shortfalls in my environment. I also need this kind of simplicity in provisioning additional capacity to compensate the shortfall. I am a true believer in SDDC and need tools that help me provision server, network and storage in a single click. Again, modern hardware and management software are making life simpler for the folks working in the datacenters.


When examining how life is easier, take for example, HP OneView. It can perform bare metal provisioning on a free blade in the enclosure, and it can also create a hypervisor host and add it to the virtual infrastructure. For example, its vCenter plug-in can create and add a new ESXi host to a VMware cluster.


This is definitely not junior school stuff. But yes, it is much needed simplicity in my world of grown-ups. HP vPV and OneView allow me to keep my data center agile enough to run an agile business.
