At some point the OBSD CVS server was something I donated. Don't think it's in this picture as I don't think it was a Dell. Never saw a picture of the thing in action actually, doh.
I avoided spending a quarter mill on F5's by deploying OpenBSD as firewalls/L4 routers but I was able to keep some of the budget... For a year there I would e-mail them every 6mo and ask what they wanted. Sad when I changed jobs and had to stop.
From what's in the picture, no more VAXen, no more SGI boxes, the SUN boxes you love are gone,(assuming you meant the Sparcstations, and not the SPARC 64 stuff), and that Zaurus sitting on top of the left VAX got put out to pasture, too.
Longsoon came and went as a platform between then and now (or at least I didn't see one in the picture, I don't remember what year they came out) and they support more ARM hardware and RISC-V as a platform now.
Assuming they don't have too much ARM hardware, they can probably fit everything they support on one rack now.
When I got to CERN back in 2002, on my office there was a stack of Sun boxes like those waiting to be collected for recycling purposes, most researchers were already into Windows 2000 or OS X on their desks, while server racks were migrated to a custom Linux distribution, later Scientific Linux.
