Drew, while this list generally isn't a sales channel, I've asked around and it appears there's really no configuration that supports more than 6 drives on the internal SATA controller. There is a small chance that the C8220x supports 8 (you should ask a rep). The best alternative we generally see customers pick is the LSI 9207 on the R720XD. It's basically a JBOD style controller which is fairly inexpensive (http://www.lsi.com/downloads/Public/Host%20Bus%20Adapters/LSI_SAS9207-8i_UG.pdf). We've recently added support for it to Crowbar as well.
Hope this helps, Simon From: crowbar-bounces On Behalf Of Drew Weaver Sent: Wednesday, October 23, 2013 9:00 AM To: crowbar Subject: [Crowbar] Cloudera hadoop deployment hardware inquiry Howdy, This isn't really just specific to crowbar but we want to use crowbar to deploy a Cloudera Hadoop cluster. The problem which we are running into is that the Dell hardware that we are targeting (the R720) does not have the ability to direct attach hard drives to the on-board SATA and as a result we are having to pay $400-$500 per node extra for a RAID controller which we don't want. Does anyone who has used crowbar in the past to build Cloudera Hadoop clusters know of a Dell server that is supported by Crowbar that has the ability to have 8x hard drives directly attached to the onboard SATA? I'm currently buying servers from the PowerEdge space but I suppose there may be something in the Cxxxx series? Thanks and sorry for list noise. -Drew
