Adjusting the Switch Thresholds

The Switch Thresholds page displays a variety of switch threshold settings.

Setting

Description

 

 

Ordered Set Error Threshold

The maximum number of OS errors allowed in a 10-second interval

 

before a port is bypassed. Setting this value to "0" returns it to the

 

factory default setting.

 

This setting is activated on the Port Smart Settings page.

 

 

CRC Error Threshold

The maximum number of CRC errors allowed in a 10-second interval

 

before a port is bypassed. Setting this value to "0" returns it to the

 

factory default setting.

 

This setting is activated on the Port Smart Settings page.

 

 

Bad Zone Recovery Hold Time

The amount of time that the switch keeps the ports in bypass mode

(measured in centi-seconds)

before attempting to re-insert the ports into the zone.

 

This setting is activated on the Advanced Functions One-Step Zoning

 

page.

 

 

Bad Zone Recovery Delay Time

The amount of time that the switch waits after a zone goes down before

(measured in seconds)

attempting to recover the zone.

 

This setting is activated on the Advanced Functions One-Step Zoning

 

page.

 

 

Port Utilization Interval

The length of time between readings of the current port’s utilization.

(measured in seconds)

 

 

 

To view the current threshold settings:

Click Advanced Functions > Thresholds > Switch.

The Switch Thresholds page appears.

Figure 3-7: Switch Thresholds page

To change switch thresholds or time intervals:

1.Enter the new value in the appropriate text box. The valid range is displayed next to the text box.

2.Click Submit.

The new value is set.

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. Built-in redundancy and failover capabilities safeguard against potential network disruptions, allowing for continuous availability of services—a crucial aspect in mission-critical environments.

The Emulex 355 also offers support for various robust networking protocols, enabling seamless integration into existing network infrastructures. Its compatibility with multiple operating systems and virtualization platforms, such as VMware and Microsoft Hyper-V, further enhances its versatility.

Another notable characteristic of the Emulex 355 is its energy-efficient design. It is optimized for lower power consumption without sacrificing performance, aligning with contemporary efforts to reduce the carbon footprint in data centers.

In conclusion, the Emulex 355 NIC is a powerful solution equipped with features that address the complex demands of modern data centers. Its combination of speed, reliability, and efficiency, along with advanced technologies, makes it a preferred choice for organizations looking to enhance their network capabilities and ensure smooth, uninterrupted operations.
