Recently I needed to make some edits on vmdk files in order to get rid of a reference to the change tracking files, as mentioned in Gabrie’s post: Cannot open the disk and could not open change tracking file.

That “old” VNX2, which I’m still perfectly happy with by the way, was a revolution in my humble opinion: multi-core everything, in short MCx. And yes, it was like everything just went faster, smoother and better.

New technologies

But with new technologies popping up every so many months now, it was time for a new mid-range storage array. Flash storage isn’t a novelty anymore, it’s a must! And the “old” hybrid arrays were fine, but needed some fine-tuning. With flash devices growing bigger every quarter or half a year and faster as well, the whole back-end needed an upgrade. The old 6 Gb back-end (x4) needed an upgrade.
