Available performance graphs

Server and Cluster Administration Guide for Hitachi NAS Platform

Part Number
You can display graphs of NAS Server data for review. For NAS modules, an external NAS Manager can display the data. The following graphs are available:
  • File system performance (operations per second)
  • File system capacity
  • Storage pool capacity
  • Node operations (a stand-alone server is displayed as a single node).
Graph Describes Units of measurement
File System Ops/Sec For each of the selected file systems (up to five), the number of operations the selected file systems is processing, either for read or write. Operations/second
File System Capacity The total capacity of a single file system, including live data and snapshot usage. MB (megabytes), GB (gigabytes), TB (terabytes), or PB (petabytes)
Note: The maximum size of a file system is 1 PB, but a 1 PB file system is only supported on an HDP storage pool.
Storage Pool Capacity The total capacity of a single storage pool. MB (megabytes), GB (gigabytes), or TB (terabytes)
Node ops Protocol operations per second on the node. Operations/second
Ethernet Throughput Ethernet throughput; both RX (received) and TX (transmitted). Mb/sec (megabits per second)
System load File system load on the hardware of the server/node.

Refer to the hardware references for information about the hardware in your server/node.
