Hi Eneko, I was considering 1 GB per TB, but I will switch that to 4 GB per TB to consider blue storage. Regarding the number of devices, Will 2 disks per node help with the cluster speed? My ultimate goal is to provide support to a second project which will be an OpenStack deployment. Oliver Audrey, I prefer to invest in hardware rather than renting it, since I want to create a private cloud. Thanks!
