  • UNMAP – Do IT!

    Pretty sure my friend Cody Hosterman has talked about this until he turned blue in the face.  Just a point I want to quickly re-iterate here for the record. Run unmap on your vSphere Datastores. Read this if you are running Pure Storage, but even if you run other arrays (especially all-flash) find a way […]
