The Nexenta Volumes Layer
This layer tracks the status of the volumes in the NexentaStor and reports how well each volume handles the I/O requests. This layer also sheds light on the space utilization in the volume and the physical memory utilization. In addition, this layer helps you understand the load on the NexentaStor by monitoring the number of users connected to the appliance.
