Generations of Modules and Switches

</h1>
<a name="wp1072737"> </a><p class="pBody">
Cisco MDS 9000 Family hardware modules and switches are categorized into generations based on the 
time of introduction, capabilities, features, and compatibilities:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1072711"> </a><li class="pSmartList1">Generation 1&#8212;Modules and switches with a maximum port speed of 2 Gbps.
</li>
<a name="wp1072712"> </a><li class="pSmartList1">Generation 2&#8212;Modules and switches with a maximum port speed of 4 Gbps.
</li>
<a name="wp1072713"> </a><li class="pSmartList1">Generation 3&#8212;Modules and switches with a maximum port speed of 8 Gbps.
</li>
<a name="wp1141606"> </a><li class="pSmartList1">Generation 4&#8212;Modules with a maximum port speed of 8-Gbps or 10-Gbps. 
</li>
</ul></div>
<a name="wp1072774"> </a><p class="pBody">
The Cisco MDS 9500 Series switches, Cisco MDS 9222i, Cisco MDS 9216A, and Cisco MDS 9216i 
switches support the Generation 2 modules. Each module or switch can have one or more ports in port 
groups that share common resources such as bandwidth and buffer credits.

</p>
<a name="wp1072775"> </a><p class="pBody">
In addition to supporting Generation 2 modules, the Cisco MDS 9500 Series switches and the Cisco 
MDS 9222i switch support the Generation 3 modules. Similar to Generation 2, each Generation 3 or 
Generation 4 module can have one or more ports in port groups that share common resources such as 
bandwidth and buffer credits.

</p>
<a name="wp1072776"> </a><p class="pBody">
Generation 3 modules are supported on the Cisco MDS 9506 and 9509 switches with Supervisor-2 
modules. The MDS 9513 Director supports 4/44-port Host-Optimized Fibre Channel switching module 
with either Fabric 1 or Fabric 2 modules, but requires Fabric 2 module for support of the 48-port and the 
24-port 8-Gbps Fibre Channel switching modules. The MDS 9222i switch supports the 4/44-port 
Host-Optimized Fibre Channel switching module. 

</p>
<a name="wp1150146"> </a><p class="pBody">
The Cisco 9500 Series switches support the following Generation 4 modules: the 48-port 8-Gbps 
Advanced Fibre Channel switching module (DS-X9248-256K9) and the 32-port 8-Gbps Advanced Fibre 
Channel module (DS-X9232-256K9). Cisco MDS NX-OS Release 6.x or higher is required to support 
the Generation 4 modules.

<a href="gen203.html#wp1072787">Table&#160;13-1</a> identifies the Generation 2, Generation 3, and Generation 4 modules, as well as the Fabric 
switches.
