HP StorageWorks 4000/6000/8000 - Enterprise Virtual Arrays, Справочное руководство

Страница: 50 / 456

NOTE:
Virtual Fabrics and Administrative Domains are mutually exclusive; they cannot run on the switch
simultaneously. To use Administrative Domains, you must first disable Virtual Fabrics; to use Virtual
Fabrics, you must first delete all administrative domains.
Switch models and fabric topologies
HP supports Meta SANs with all B-series switches in either HP standard or customized topologies.
You must follow all B-series and Meta SAN fabric rules. For more information about Meta SANs, see
“
B-series switches and fabric rules ” on page 93.
Benefits
A Meta SAN:
• Allows fabric connections (without the need to merge fabrics), providing a high level of fault
nl
isolation and centralized fabric management
• Connects multiple SAN islands (independent fabrics), enabling selective resource sharing
• Eliminates the need to move and re-cable equipment in different fabrics
• Allows connection of fabrics with the same domain ID and zoning definitions
• Reduces the impact of scaling limits for individual fabrics
• Increases levels of storage consolidation
• Provides centralized backup for multiple fabrics
• Allows higher level of fabric management and management consolidation
B-series Virtual Fabrics with IFR
The B-series Virtual Fabrics feature allows you to partition fabrics. You create partitions in the fabric
by creating logical switches within a physical switch and by creating logical fabrics within a physical
switch or across multiple switches. This provides a high level of isolation between Virtual Fabrics
partitions or logical fabrics, allowing you to view individual Fibre Channel subnetworks in a B-series
fabric.
The IFR feature allows you to configure devices in one logical fabric for access to devices in another
logical fabric. B-series Virtual Fabrics and Virtual Fabrics with IFR are included on selected 8 Gb
switches only.
Switch models and fabric topologies
HP supports Virtual Fabrics in either HP standard or customized topologies. You must follow all B-series
fabric rules. For more information, see “
B-series switches and fabric rules ” on page 93.
Benefits
Virtual Fabrics:
• Isolate fabric services and minimize fault propagation
• Allow multiple secure fabric partitions over the same physical infrastructure
• Restrict device access for improved control and security
• Provide selective device access and sharing using the IFR feature
