Know Your Virtual Workloads: Block Size & Workload Shift


To properly design and optimize your data center, it’s important to understand various workload characteristics, how they change over time, and how they impact application performance. I’ve identified the top six things you should know about your virtualized workloads.

In my last post, I looked at two characteristics of your VMs that are traditionally overlooked in the data center: the different effects that reads and writes have on VMs, and how different access patterns impact performance. Failure to recognize and appropriately measure these things can adversely impact application performance and lead to high IT costs.

In this post, I’ll address two other characteristics that are equally important: block sizes and workloads.
