serial port concentrators (console servers) and serial console redirection

We use an SCS-320 from Logical Solutions ( that  
works really well and their tech support has been very good.

But do you need a console server with your poweredge boxes? Thanks to  
IPMI's Serial-over-LAN (SOL) on the Poweredges, we're moving away  
from console servers. The advantages of SOL are:

* Less hardware to deal with (support, monitor, take up space,  
electricity, etc.)
* No extra cable running through your cabinet per server for the  
serial port -- it works OOB on NIC1
* $0

A console server is still necessary for non-IPMI devices, of course,  
but it seems to me that console servers are a dying breed.
