Same problem as with the Y series - it is PCI only. I do not know any
modern 1U server where you can use 2 PCI cards (2 uPCI are ok).

Well, I did not have any particular problems - it's just that a solution
using a standard Linux server and console seems much better ...
The TS are slow (especially the ssh connections) and too expensive.
I had to write some (very strange) scripts to get a functionality
similar to a "normal" Linux box (eg. for log rotation) and it lacks many
standard tools (I do not want to have to cross-compile every little
utility myself).
Conserver also seems much better regarding the core console
functionality and it seems easier to manage. Ever tried to find out to
which of your 5 console servers a particular host is attached? I wrote
some scripts to do this (that was before I heard of conserver).
Of course I will still use our existing console servers (integrating
them with conserver seems easy enough), but for a new system conserver +
~  1U server + 2 RocketPort 32-port cards seems to be the better solution.
