Below is a logical diagram of my lab. For routing and switching, I own four (4) 2801 ISRs and three (3) 2811 ISRs. Please refer to the info below for cards, memory, and DSP resources; items italicized in red are devices that I plan to add to my lab in the relative near future. One of the 2811s functions as both an Access Server for reverse telnet to the console ports, as well as a frame relay switch. I also have a Catalyst 3750-24PS switch. For PSTN simulation, I have a first generation Adtran Atlas 550 with four PRI ports and 8-ports of FXS. Finally, I have a handful of analog phones, two (2) 7962Gs and two (2) 7942Gs.
I also own three servers: one DL320 G2 with two 250GB HDs and 4GB of memory; a DL320 G3 with two 750GB HDs and 4GB of memory; and a MCS7816 with two 160GB HDs. My plan for these is to install VMWare ESX on each, and then build out everything in virtual machines. This will make restoring configs very efficient and easy. Thus far I’ve gotten ESX to install and work on the DL320 G3. Next I will see how the install goes on the G2, and finally the MCS7816 (which is essentially a DL320 G5 with Celeron, if my research is correct).

I can access my lab remotely via VPN over a PIX501 that is connected to my Comcast Cable Modem. It appears that Comcast rarely if ever changes their customers' IP; I've had the same one for over a year. Once I VPN in, I have to APC SNMP enabled power strips (AP9225 and AP9211). These are awesome for remote power management, although I probably scare the heck of out of my dog when I turn my lab on remotely.
