We are running firmware version 3.6.1 on our two vSZ controllers against about 400 R710s and a handful of T710s. vSZ firmware version 5 came out a week ago and after reading the release notes we are still trying to decide if we should upgrade or wait until 5.1 comes out.
Has anyone upgraded to vSZ 5 yet? If so, how is it working for you?
Well, to be fair there are differences (but no major negative differences I would like to mention). The bug fixes mentioned was enough to move over to it, as for new features, there isn't any killer features (unless you have their switch line).
