VSAN Advantages

</h1>
<a name="wp1072669"> </a><p class="pBody">
VSANs offer the following advantages:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1072671"> </a><li class="pSmartList1">Traffic isolation&#8212;Traffic is contained within VSAN boundaries and devices reside only in one 
VSAN ensuring absolute separation between user groups, if desired. 
</li>
<a name="wp1072673"> </a><li class="pSmartList1">Scalability&#8212;VSANs are overlaid on top of a single physical fabric. The ability to create several 
logical VSAN layers increases the scalability of the SAN. 
</li>
<a name="wp1072674"> </a><li class="pSmartList1">Per VSAN fabric services&#8212;Replication of fabric services on a per VSAN basis provides increased 
scalability and availability.
</li>
<a name="wp1072676"> </a><li class="pSmartList1">Redundancy&#8212;Several VSANs created on the same physical SAN ensure redundancy. If one VSAN 
fails, redundant protection (to another VSAN in the same physical SAN) is configured using a 
backup path between the host and the device.
</li>
<a name="wp1072677"> </a><li class="pSmartList1">Ease of configuration&#8212;Users can be added, moved, or changed between VSANs without changing 
the physical structure of a SAN. Moving a device from one VSAN to another only requires 
configuration at the port level, not at a physical level.
</li>
</ul></div>
<a name="wp1072678"> </a><p class="pBody">
Up to 256 VSANs can be configured in a switch. Of these, one is a default VSAN (VSAN 1), and another 
is an isolated VSAN (VSAN 4094). User-specified VSAN IDs range from 2 to 4093.
