Description

 

 

Stealth Intelligent Change

Stealth Intelligent Change Manager provides stability and control over

Manager

change notification disruptions on a port basis. Options include:

 

• Off: No Change Protection – no Stealth Intelligent Change

 

Manager control.

 

• Initiator: Only Receive Changes – devices attached to the port can

 

receive change notifications but will not propagate change

 

notifications generated by that port to other ports.

 

• Target: Only Send Changes – propagates change notifications

 

generated by the port to other ports but will not allow devices

 

attached to the port to receive change notifications from other

 

ports.

 

• Switch-Switch: Send and Receive Changes – allows change

 

notifications to propagate between switches.

 

• Custom-1 – Note: This setting should not be used unless directed

 

to do so by a customer service representative.

 

 

Change Notification on

The switch normally operates under the condition that when a device

Insertion

is inserted onto the network, a change notification is generated.

 

However, this condition is not always true when connecting hubs or

 

switches together. In some instances, it is possible to connect two

 

zones together without the zones realizing that multiple AL_PAs exist

 

with the same values.

 

When this policy is enabled, the switch always generates a change

 

notification to ensure that the proper system updates are performed.

 

However, when a device is removed (for example, an initiator or

 

target), the removal does not generate a change notification and

 

there are no system updates performed.

 

 

Change Notification on

This policy is similar to the Change Notification on Insertion policy,

Removal

except for the change notification being sent when a device is

 

removed rather than inserted.

 

When this policy is enabled, the switch always generates a change

 

notification to ensure that the proper system updates are performed.

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.
