Feature licenses License keys provide a way to expand the capabilities of your switch and fabric as your needs grow. The HP StorageWorks 8/20q 4-port Upgrade License activates additional Fibre Channel ports to 12, 16, or 20 ports. Applying a license key is not disruptive, nor does it require a switch reset. To order a license key, contact your switch distributor or your authorized reseller. For more information, see "Installing feature license keys" (page 44). The following license key feature is available: • The HP StorageWorks 8/20q 4-port Upgrade License enables additional SFP ports to12, 16, or 20 ports. Multiple switch fabrics By connecting switches to one another, you can expand the number of available ports for devices. Each switch in the fabric is identified by a unique domain ID, and the fabric can automatically resolve domain ID conflicts. Because the Fibre Channel ports are self-configuring, you can connect 8/20q Fibre Channel Switches together in a wide variety of topologies. When planning your fabric, consider your topology and cabling requirements. Transparent routing to a legacy fabric is also possible using TR_Ports. For more information about Storage Area Network (SAN) connectivity, see the SAN Design Reference Guide available at the HP website: http://www.hp.com/go/SANdesignguide. Optimizing device performance When choosing a topology for a multiple switch fabric, you should also consider the proximity of your server and storage devices and the performance requirements of your application. Storage applications such as video distribution, medical record storage/retrieval, or real-time data acquisition can have specific latency or bandwidth requirements. The 8/20q Fibre Channel Switch provides the lowest latency of any product in its class. For information about latency, see "Performance" (page 18). However, the highest performance is achieved on Fibre Channel switches by keeping traffic within a single switch instead of relying on ISLs. Therefore, for optimal device performance, place devices on the same switch under the following conditions: • Heavy I/O traffic between specific server and storage devices. • Distinct speed mismatch between devices such as the following: • An 8-Gb/s server and a slower 4-Gb/s storage device • A high performance server and slow tape storage device 20

Optimizing device performance

When choosing a topology for a multiple switch fabric, you should also consider the proximity of your

server and storage devices and the performance requirements of your application. Storage applications

such as video distribution, medical record storage/retrieval, or real-time data acquisition can have specific

latency or bandwidth requirements.

The 8/20q Fibre Channel Switch provides the lowest latency of any product in its class. For information

about latency, see ”

” (page 18). However, the highest performance is achieved on Fibre

Channel switches by keeping traffic within a single switch instead of relying on ISLs. Therefore, for optimal

device performance, place devices on the same switch under the following conditions:

•

Heavy I/O traffic between specific server and storage devices.

•

Distinct speed mismatch between devices such as the following:

•

An 8-Gb/s server and a slower 4-Gb/s storage device

•

A high performance server and slow tape storage device
