CHAPTER 3 SWITCH MANAGEMENT

USER’S GUIDE

 

To configure multiple-switch zoning, do the following for each switch:

1.Plan which ports should belong in each zone.

2.From the One-Step Zoning page, select the appropriate ports for each zone.

Switch A

Switch B

Figure 3-18: Zones Coordinated on Multiple Switches

3. Ensure the Zoning Active check box is selected for both switches.

Caution: Clearing the Zoning Active check box will deactivate all zones, which may degrade system performance or compromise security.

4. After making changes, click Submit.

AL_PA Zoning

Another zoning configuration is AL_PA zoning, which enables users to specify that certain devices only communicate with one another. AL_PA zoning is only accessible through the Command Line Interface (CLI). Refer to the InSpeed Storage Switch CLI Reference Guide for additional information.

Recovering a Bad Zone Automatically

Bad zone recovery policy automatically recovers traffic if a device has brought down the zone. The zone state is monitored continuously. If ports are inserted into a zone, but the zone state never transitions to the Zone Up or Zone Active state after a set period of time (Hold Time), all devices in the pertinent zone are bypassed and then allowed to reinsert. There is a secondary timeout, the Bad Zone Recovery Delay Time, that can also be configured. The Bad Zone Recovery Delay Time causes a delay before ports are allowed to reinsert, which prevents a high "thrashing" level of port insertions and de-insertions and ensures that some devices can reset. The Bad Zone Recovery Hold Time and Delay Time threshold settings are available on the Advanced Functions Switch Thresholds page.

When this policy is enabled with the associated PTBI policy, the device causing a zone to go down is not allowed back into the zone due to the PTBI policy, which allows the system to return to normal operation. The combination of the Bad Zone Recovery and PTBI policies has resulted in significant improvements to SAN availability.

Note: The Bad Zone Recovery policy is enabled by default. If the Bad Zone Recovery policy is disabled, use the following instructions to enable this policy for the appropriate zones.

To activate bad zone recovery:

1.Click Advanced Functions > One-Step Zoning.

2.Under Bad Zone Recovery, select the check boxes for the appropriate zones.

3.Click Submit.

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.
