The following settings are available.

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 gener-

 

ated 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 notifica-

 

tions 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 is

Insertion

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 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, except

Removal

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 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.
