Anyone who has worked at length with EMC Clariion or VNX would be familiar with the good old NAR files. These are the important little files where statistics about array performance are saved/archived, so you can them open them in Analyzer and review the massive amount of performance metrics and data stats from your array.

This particular array was overdue for an upgrade anyway, but has special change control requirements. It affects VNX1 series arrays that have particular 300GB & 600GB 15K SAS drives with the […]

It’s fast, efficient and you get info you need quickly. Most of these commands will be relevant to series 1 […]
