For our ~400 TB Ceph deployment, we bought:
(2) R720s w/ dual X5660s and 96 GB of RAM
(1) 10Gb NIC (2 interfaces per card)
(4) MD1200s per machine
...and a boat load of 4TB disks!
In retrospect, I would almost certainly would have gotten more servers. During

Thank you all for comments,
So to sum up a bit, it's a reasonable compromise to buy :
2 x R720 with 2x Intel E5-2660v2, 2.2GHz, 25M Cache, 48Gb RAM, 2 x 146GB, SAS
6Gbps, 2.5-in, 15K RPM Hard Drive (Hot-plug) Flex Bay for OS and 24 x 1.2TB,
SAS 6G

Ah.
Every once in a while they make their bios complain when it finds a
non-"Dell approved" disk. Once enough customers start screaming they
release a "bios update" t
