EMC VNX (and general) Acronyms

The EMC VNX and VNXe storage arrays seem to have more acronyms tied to them than other storage systems (even IBM).

This page is just a simple list of these acronyms with general IT acronyms added in.

Most of this info is available elsewhere online, but not in a mobile-ready format, so this is just another resource for that.

If you find this handy and want to take it with you, the table can be exported as an Excel spreadsheet or common CSV file.
