Storage server statistics

The NAS Platform provides extensive statistics that can be used to monitor operation. For NAS modules, an external NAS Manager can display the available data. Statistics include:

  • Networking (Ethernet and TCP/IP)
  • Fibre Channel ( (HNAS server only)
  • File access protocols (CIFS, NFS, and FTP)
  • Block access protocols (iSCSI)
  • Management access for supported access protocols (SNMP and SSC for some NAS server models, or SNMP, SSC, Telnet, and SNMP for more recent NAS server models)
  • Virus scanning

Data is gathered at short intervals (typically every 10 seconds) and these data points are kept for the previous 24 hours. For data older than 24 hours, the data is periodically aggregated; the raw data is averaged and only a single hourly average value is kept. Aggregating the data in this fashion minimizes the overhead of millions of data points, and allows data to be retained long-term storage. If all the data points were retained, the data set would quickly grow, and would become unmanageable. The system stores the performance data for 1 year in order to provide a long-term, historical view of system performance.

In addition to the statistics, performance graphs are also provided.

Network statistics

Fibre Channel, Ethernet, and TCP/IP statistics for the server (per port in 10-second timeslices) are available. These statistics pages display activity since the previous reboot, or since the point when statistics were last reset.

Ethernet statistics

Ethernet statistics (per port in 10-second time slices) are available for activity since the previous reboot or since the point when statistics were last reset.

Data access and performance statistics

The server provides measures and tools for monitoring the impact of network clients on internal resources. In particular, the server provides:

  • Server and file system load statistics
  • File system NVRAM usage statistics

Server and file system load statistics

In addition to Ethernet and Fibre Channel throughput statistics, server performance can also be measured in operations per second (ops/sec). The NAS Manager provides a graphic representation of ops/sec, at two levels:

  • Total operations per server.
  • Total operations per individual file system.

The total operations on a server is an aggregate of the operations performed by all file systems hosted by that server.

Understanding the performance profile of servers and individual file systems is especially useful in environments where more than one server is installed, as it enables intelligent relocation of EVSs or file systems to more equally distribute the load among the available servers.

Displaying operations per second (ops/sec) statistics

  1. Navigate to Home Status & Monitoring, and select either File System Ops/Sec or Node Ops/Sec.

    Item Description

    Custom Click to specify a custom date range, which includes the from and to dates and times. Click OK to initiate the graph.
    Download Download statistics on the graph as a single CSV table.
    Select 1-5 File Systems Displays all the file systems in the currently managed server or cluster. To select file systems, and display the performance data for that file system:
    1. On your keyboard, press and hold the Control (Ctrl) key.
    2. Highlight up to five file systems.
    3. Click OK.
    Ops/Sec The number of recorded operations per second.
    Date/Time The currently selected date/time range.

Displaying file system NVRAM statistics

The File System NVRAM Statistics page displays NVRAM activity.
NoteWhen an EVS has a Read Cache file system, no NVRAM statistics are presented.
