I have a Dell R710 2U server. It's pretty heavy, so it seems to me like it needs support in the front and the back, but we only have a 2-post rack. The rack is bolted to the floor, so it's pretty sturdy.
In general, is it okay to flush-mount a 2U server in a 2-post rack?
I have a much lighter 1U server mounted there, and it seems okay. Also, the tech guide for the R710 says:
Support for flush and center mount installation in CEA-310-E compliant 2-post racks (1U & 2U only)
But it just doesn't seem right to me.
Thanks!
Update: I contacted Dell tech support, and they pointed me to a 3rd party solution from racksolutions.com for center-mounting the R170 in a relay rack. So I'll try that + one of the shelves suggested by Zypher.
I don't think I'd be comfortable doing that either. We use Two post Rack Shelves to help support 2-4U server in 2 post racks.
If it was me I would not flush mount a server in a 2 post rack I would center mount all my servers. I don't like to put servers in a Relay rack as they are built more for telco and network equipment. They will work for servers as the mounding brackets have been manufactured to work with the Relay racks. But in general I don't like to use relay racks to mount servers.
If it were me, and the manual said that it is supported in a CEA-310-E compliant 2-post rack, then I would verify that my rack meets the compliance and call Dell to find out what mounting hardware to use.
If you can center mount it, it should be fine. I wouldn't flush mount it due to the amount of torque that will be put on the mounting hardware from the rear end of the server just dangling in space.
