Dell MDSM v11.25 +

Good Day.

I'm struggling to find MDSM v11.25+ has I need to reinstall our Server OS due to buggy and unstable operation. (screenshot attached)

Currently have 1x MD3200i + 1x MD3800i Storage Servers that need to be managed after reinstall of OS but can only source v.6.5.0.1. - is this the latest release or am I reading the Current v. correctly?
