Hi Ector, *RAID 1 would cut your per node disk capacity in half (1.5TB), so at 4 nodes, your overall cluster capacity would only be 6TB.* As I mentioned every server has two 3TB HDD (total 6TB), so the cluster size would effectively be 12TB in a Raid 1 configuration. The biggest issue here is t

On the Release notes, theres a new section recommending the deletion of all previous AAE info before upgrading to 1.4.8. What are the risks (if any) of not doing this (the deletion) beside the wasting resources? Best Regards ___ riak-users mailing list

Hi everybody, I have a couple of questions regarding the performance requirements for a 12TB Riak cluster, specifically: 1) I wonder if four servers, each one with the following spec, can handle it: 6 cores at 2.20GHz (15MB cache), 16GB of memory, and two 3TB HDD in a Raid 1 configuration. And if
