Ah, yeah. Just pick a server that can hold a bunch of drives. We've seen that some of them have issues with eg oversubscribed SAS/SATA expanders so you'll want to check their basic disk capability, and you want enough compute power to handle each drive (we recommend 1GHz of CPU and 1GB of RAM per OSD/disk), but within those constraints you can go wild. Like John said, you probably want more than one server for a production deployment (just in terms of reliability), but in terms of the software you can configure everything to work that way. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com > > > > Regards, > > Christopher Coulson > ------------------------------------------------------- > Systems Administrator > CPI Group, Inc. > 3719 Corporex Park Drive, Suite #50 > Tampa, FL 33619 > Phone: 813.254.6112 (ext. 635) > Fax: 813.514.0637 > Email: chrisc@xxxxxxxxxxxxxxx > ------------------------------------------------------- > > > On Tue, Apr 30, 2013 at 4:03 PM, Gregory Farnum <greg@xxxxxxxxxxx> wrote: >> >> On Tue, Apr 30, 2013 at 12:35 PM, Chris Coulson <chrisc@xxxxxxxxxxxxxxx> >> wrote: >> > Hopefully I'm performing the correct task to ask a quick, >> > facepalm-inducing >> > question: >> > >> > >> > After attending the Openstack Summit in Portland, my company is planning >> > to >> > implement our own private cloud and are beginning to develop ideas >> > regarding >> > its architecture.
