Port Recovery

The following settings are available.

Setting

Description

 

 

Bad Device Recovery

When a port is already inserted into a zone, the port transforms F8 Failure

 

notifications into F7 Initialization notifications. When this occurs, the port

 

is bypassed and F7 Initialization notifications are allowed in the zone.

 

Once the initialization is complete, the Bad Zone Recovery Policy is

 

operational and prevents a port that continues to transmit F8 Failure

 

notifications from inserting into the zone.

 

Note: If this policy is disabled while the Bad Zone Recovery policy is

 

enabled, a zone that does go down will still allow the Bad Zone Recovery

 

policy to reset the zone and allow ports to be reinserted.

 

When enabled, this policy prevents devices that send F8 Failure

 

notifications from inserting into a zone. The ability to remove devices that

 

generate F8 Failure notifications automatically and instantaneously

 

guarantees continual system operation.

 

When disabled, this policy allows devices that send F8 Failure

 

notifications to insert into a zone and does not consider F8 Failure

 

notifications when determining whether to insert a device or not.

 

 

Clear on Stall

In situations where the switch is operating in switching mode, some

 

devices may fall into an operating mode where the device has opened a

 

target but has not released the connection to the target. When this policy

 

is enabled, the switch can detect this condition and automatically recover

 

when this situation arises.

 

 

Bypass on No Activity

The switch detects the amount of time a data stream has gone without

 

receiving a comma. The time setting is set to 100 (.001 seconds). When

 

this policy is enabled, the switch bypasses the disruptive port when the

 

threshold is exceeded.

 

 

Bypass on Ordered Set Error

Ordered Set (OS) errors are detected and counted for each individual

 

port. When this policy is enabled, a port is bypassed when its OS count

 

exceeds the threshold setting. The threshold setting is based on the

 

number of ordered set errors identified in 10 seconds.

 

Note: This threshold setting can be adjusted on the Web Manager’s

 

Advanced Functions Switch Thresholds page.

 

 

Bypass on CRC Error

Cyclic Redundancy Check (CRC) errors are detected and counted for

 

each individual port. When this policy is enabled, a port is bypassed when

 

its CRC count exceeds the threshold setting. The threshold setting is

 

based on the number of CRC errors identified in 10 seconds.

 

User intervention is required to return the port into the zone. Recovery

 

methods include replacing the defective component, cycling power to the

 

device on the port, removing and reinserting the bypassed port, or cycling

 

power to the switch.

 

Note: This threshold setting can be adjusted on the Web Manager’s

 

Advanced Functions Switch Thresholds page.

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.
