VSANs for FICON and FCP Mixing

</h1>
<a name="wp1072662"> </a><p class="pBody">
Cisco MDS 9000 Family FICON-enabled switches simplify deployment of even the most complex 
mixed environments. Multiple logical FICON, Z-Series Linux/FCP, and Open-Systems Fibre Channel 
Protocol (FCP) fabrics can be overlaid onto a single physical fabric by simply creating VSANs as 
required for each service. VSANs provide both hardware isolation and protocol specific fabric services, 
eliminating the complexity and potential instability of zone-based mixed schemes.

</p>
<a name="wp1072665"> </a><p class="pBody">
By default, the FICON feature is disabled in all switches in the Cisco MDS 9000 Family. When the 
FICON feature is disabled, FC IDs can be allocated seamlessly. Mixed environments are addressed by 
the Cisco NX-OS software. The challenge of mixing FCP and FICON protocols are addressed by Cisco 
MDS switches when implementing VSANs. 

</p>
<a name="wp1072666"> </a><p class="pBody">
Switches and directors in the Cisco MDS 9000 Family support FCP and FICON protocol mixing at the 
port level. If these protocols are mixed in the same switch, you can use VSANs to isolate FCP and 
FICON ports. 

</p>
<a name="wp1072667"> </a><p class="pBodyAutonumRel">
<strong>Tip	&nbsp;&nbsp;&nbsp;</strong> When creating a mixed environment, place all FICON devices in one VSAN (other than the default 
VSAN) and segregate the FCP switch ports in a separate VSAN (other than the default VSAN). This 
isolation ensures proper communication for all connected devices.
