@mgerdts lol I had completely forgotten those were Netras but you're exactly correct.

The bottom two were "eBay specials" as we liked to call them. I think the Netras we actually bought new and might have been our first bought-new server-grade hardware.

I can't honestly remember why we went with the Netras since we were primarily a FreeBSD shop. I vaguely recall being pissed off at Solaris all the time.
