Viewing Ordered Sets

This page displays the Ordered Sets that are being transmitted on the switch for each port since the last time the page was displayed. Ordered Sets are used when communicating data across networks to indicate actions, events, or status regarding the data. A list of detected Ordered Sets and their indications is provided below.

To view ordered sets:

1.Click Advanced Functions > Diagnostics > Ordered Sets. The Ordered Sets page appears.

Detection

Indication

 

 

 

 

 

End of Frame

An End-of-Frame (EOF) delimiter has been detected; frames are present. (An EOF

 

(EOF)

immediately follows the CRC of a frame and signals the frame’s end.)

 

 

 

 

 

 

Start of Frame

A Start-of-Frame (SOF) delimiter has been detected; frames are present.

 

 

(SOF)

 

 

 

 

 

 

Idle

Sequences of IDLEs are being transmitted to maintain link activity; no other data is

 

 

being transmitted.

 

 

 

 

 

 

ARB(FF)

ARB(FF)s are being transmitted to maintain link activity; no other data is being

 

 

 

transmitted.

 

 

 

 

 

 

ARB

A port is arbitrating for network access to perform a task.

 

 

 

 

 

 

Read Ready

The receiving node on this port has sent an R_RDY signal, indicating that it is

 

 

(RRDY)

ready for a frame to be transmitted over the link.

 

 

 

 

 

 

Close (CLS)

The port is attempting to begin the process of closing the current FC-AL circuit.

 

 

 

 

 

 

Open (OPN)

The port is attempting to open communications with another port.

 

 

 

Note: As is the case with some ordered sets, an OPN may not go all the way

 

 

 

around the FC-AL, instead stopping at its destination.

 

 

 

 

 

 

F8 Failure

A non-switching port has detected a failure on its receive input, is notifying other

 

 

 

ports, and is determining whether the network is still operational.

 

 

 

Some events that could cause the port to detect network failure follow:

 

 

 

• A device has failed or has been powered off.

 

 

 

• The physical connection between the transmitter and receiver is broken.

 

 

 

• Activating the port bypass circuit does not typically result in a network failure.

355 specifications

The Emulex 355 is a high-performance network interface card (NIC) designed specifically for data centers requiring advanced connectivity, reliability, and speed. With the rapid evolution of data transmission technology, the Emulex 355 stands out due to its robust features and capabilities that cater to the demands of modern IT infrastructures.

One of the key features of the Emulex 355 is its support for 10 Gigabit Ethernet, which allows for significantly faster data transfer rates compared to standard Gigabit connections. This increased bandwidth is essential for handling large volumes of data traffic, particularly in virtualized environments and cloud computing applications. Its high throughput ensures that data can be transmitted rapidly across networks, minimizing latency and improving overall performance.

The Emulex 355 employs advanced technologies such as iSCSI Offload and FCoE (Fibre Channel over Ethernet), which help enhance data processing efficiency. These technologies allow the card to offload processing tasks from the host system's CPU, reducing the load on server resources and optimizing performance. The result is a more efficient system that can handle more concurrent connections and processes without being overwhelmed.

In addition to speed and efficiency, reliability is paramount in data center operations. The Emulex 355 includes features like error detection and correction, ensuring data integrity during transmission.
