Hi Folks My name is Steve Watt and I work in the CTO Office at Red Hat. I've recently spent quite a bit of time designing single rack and multi-rack infrastructures for Spark for our own hardware procurement at Red Hat and I thought the diagrams and server specs for both Dell and HP would be useful to the broader community as well. Even if folks don't want to go with my exact design, having the designs as a starting point should save quite a bit of time. I think I can fold this quite easily into http://spark.apache.org/docs/latest/hardware-provisioning.html
However, before submitting a pull request for the modified page I thought I'd send this note up front and see if anyone wanted to provide some feedback first. If there is none, I'll submit the pull request early next week. Regards Steve Watt
