I can confirm, having had to strip and repair one of mine, that the only shared components common to all 4 slots are: 1. The metal shell 2. The fan control board 3. the SATA backplane, at least physically. The backplane the blades plug into is split into (independent) top and bottom halves. The power distribution/sharing system is split into (1+1 redundant, connected) top and bottom halves. The SATA backplane, although shared, appears to be 99% passive and signal traces appear to be highly localized; power is another story for obvious reasons; a catastrophic failure in one SATA drive could propagate to other drives, but would be fused at the power distribution board(s). It's inaccurate to characterize the 4 servers in a C6100 chassis as **completely** indepedent, but I can confirm that you definitely can pull and replace individual blades without affecting the others. In my case, I have enough 6 other servers running at that site, so I can put one router in each chassis, thus ensuring complete separation all the way out to the ethernet switch and/or the shared UPS (take your pick). -- -Adam Thompson athom...@athompso.net

Yes Supermicro twin power supply is shared, but it is redundant, so you need both power supply to fail to have both FW failing (one power supply can power both systems). >Nice :) Even if the FW were only sharing the same case the idea is dumb >because you will have to take off line good FW to fix the one which failed. You can remove a system "hot-swap" without affecting the other one. Only a problem if you cannot remove *only* the failing system due to cabling or other mechanical issue. The only single point of failure I can think of is the backplane connecting everything together (both systems, both power supplies and interconnection to the front panel). BR Michel

Nokia made a frame that held 2 of them in a 1U standard 19 inch rack space. OpenBSD will run on them, but it requires a little effort to get it to work. Or it did the last time I tried it. My efforts to get OpenBSD to work on them is either in the archives of this list or tech@. The current CheckPoint 2200 series is of similar width and not as deep as the IP260. I don't know if they offer a mounting plate to rack 2 side by side. We either sit them on top of something in the rack or install a shelf in the rack. I've yet to try OpenBSD on one though. If we have a spare 2207 at work, I'll see if OpenBSD will run on it. Stan

there is 23 model that are twin model in 1U: http://www.supermicro.com/products/nfo/1UTwin.cfm But they share the power supply. May be that's what you didn't like.

There are various companies that produce 1U cases that can hold two Soekris, PCEngines, etc. boards, e.g. Kerberos (Europe) http://www.kerberos.si/ENG/Soekris19.htm Yawarra (Australia) http://www.yawarra.com.au/products/servers/ -- Christian "naddy" Weisgerber na...@mips.inka.de
Re: 1U / 2 Computers? For redundant FW pair
I take back the HP suggestion, since it was pointed out these share a lot of components between the servers as well. This looks interesting, though it may be under-powered depending on your needs: http://www.hacom.net/catalog/mars-ii-twin-blade-d525-pfsense-1u-server With the right search terms, I found a number of other half-width 1u servers designed for this application that may also be appropriate. They seem to basically repackage mini ITX boards.

I think Dell used to have servers in its 'Cloud' line that fit 2 machines in 1U, though IIRC they were a little pricey. I couldn't find them again when searching. The HP SL2x170z server pulls off a similar feat - you can find several on ebay, though it may be discontinued as well.

Re: 1U / 2 Computers? For redundant FW pair
Hi Alan, some time ago I've had a look at them. Supermicro still seem to have 1U Twin-Server in their List. Unfortunately I can't say anything about running them - they are still on my "wishlist". On the other hand - does anybody know alternatives ? Just in case of not ending up in some kind of vendor-lock-in issue. For "weaker" hardware I've allready tested the APU-Boards in a 1U Dual-Box. I was able to push ~750 Mbps through them with pf enabled (just the default rules) Workstation ---> APU 1 ---> APU 2 just with a simple iperf test. Also when using ipsec in this test-setup, iperf was able to push ~60Mbps through the tunnel (ase-128).

1U / 2 Computers? For redundant FW pair
I know that Supermicro has some interesting side-by-sides starting at 2U, but I'm not aware of anything in 1U. Basically I'd like to have my redundant FW pairs take up less rack space. I guess another option would be half-width 1U if anything like that exists, and install a rack shelf. -- "Don't eat anything you've ever seen advertised on TV" - Michael Pollan, author of "In Defense of Food"
