Is there a provider or simple custom build method to fit one or more seperated physical systems (anything able to run server CPUs, with or without HDD) in a 1u rackmount chassis?
ASUS makes a 1U server that should work for you, the RS702D-E6/PS8
Supporting Intel® Xeon® 5500 series processor, RS702D, the dual 2-Processor systems provide extreme performance for customers with 4-way, 16-core computing capability in 1U. The design of 1~8 hot swap 2.5” SATA/SAS HDDs support is space-saving with its normal form factor.
There are providers that will do you four servers per 2 units, by combining two servers into 1RU. Both Dell and HP have offerings in this regard, but I can't seem to find the links to either of them at the moment.
So, if you're looking to squeeze two servers into 1RU, then no, but if you want 4 servers in 2RU, then yes.
Supermicro has the Twin series: 1U with 2 boards and 4 boards in 2U (with redundant PSU)
