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.
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.
