To help with determining how much more data can be added to a cluster, InsightIQ 3.1 has added a capacity report. It looks at the last file systems analytics job using the logical space vs physical space used for the file data already on your cluster to estimate how much more data you can add to the cluster. This is making an assumption that the data you add to your cluster will similar to the data already on the cluster. It also give a very nice breakdown at to how the numbers was arrived at. The only downside is that it currently only works with clusters running OneFS 7.2.   Welcome to InsightIQ 3.1    Here is a screenshot of the calculations with a quick explications of each line that I wrote. Admittedly, it's not the best screenshot as this test cluster has a lot of thin provision VMDK files on it, so the overhead looks much lower than most environments.   [IMAGE]   There is a lot of data here, but it does help administrators understand what is currently consumed for storage and how the estimated value of more capacity is calculated. This is very useful, as the adaptive nature of OneFS is so different from other storage systems, it can bring a lot of clarity to administrators. This page is laid out and calculated like a simple subtraction equation to make it easy to follow. Note: all number are in base 2.
Hello,  We are using 5 node NL-SAS cluster which is total of 180 TB drive capacity.  Used and available cluster capacity summing up to 154 TB.  There is some space used for vds which is not showing up in the graph.   Could  some one please explain how total storage is used and how to verify remaining 26 TB being used for different purposes  through command line or GUI.  We are calculating capcity metrics.   Thanks
