HDS HNAS Platform 3x00 - undocumented NFS feature

If you are using a HNAS from BluARC(HDS) and a vSphere environment which supports Thin-Provisioning there is a possible problem: While deploying a virtual machine with thin-provioned disks (thin provisioning is displayed as supported for the datastore) the deployed virtual machine shows up thick virtual disks after creation.



If this happens, there is an undocumented feature for the NFS server parameters:

enable_sparse_block_counts

After the counts are enabled the documentation of the provisoned space into the vSphere environment is correct.
