SAN Controller Statistics Descriptions

SAN Controller protocol statistics provide an overview of the Controller ports on your Oracle FS System.

You can review the status of the following:

Name

Identifies the name of the selected Controller.

Port Type

Identifies the Controller port protocol type, FC, or iSCSI.

Slot Number

Identifies the Controller PCI slot assignment.

Port Number

Identifies the port numbers which are 0 or 1.

Negotiated Speed

Displays the transmission speed in Gbps/⁠second for the port. The transmission speed is negotiated between the HBA or FC switch and the Controller.

Throughput (per Second)

Identifies the throughput in MB/second.

Read: Identifies the read throughput in MB/second.

Write: Identifies the write throughput in MB/second.

I/O Latency

Identifies the time in milliseconds to read or write data.

Displays the following:

Read: Identifies the time to read data in milliseconds.
Write: Identifies the time to write data in milliseconds
Combined: Identifies the combined amount of time to read and write data in milliseconds.

I/O Size

Identifies the average size of the read and write operations.

Commands Received (per Second)

Displays the number of read and write commands received on the Oracle FS System each second over the last sampling period.

Channel Errors Since Activated

Displays the cumulative number of channel errors that have occurred since the Controller was activated.

Collection Period

Identifies the start and end times at which information was last collected from the Oracle FS System. Data is collected for a two-minute period and the data is refreshed every two minutes.

You can view more detailed information about Controllers by viewing details for a selected Controller. Detailed information is available for Fibre Channel (FC) or iSCSI Controllers, depending on the type of Controller selected.

You can use this statistical information to monitor the Controllers or to compare Controller characteristics for planning improvements to your system.
