Cisco Cisco Email Security Appliance C170

Cisco UCS servers (blade or rack-mounted) are the only supported hardware platform for the virtual 
appliance. VMware ESXi version 4.x and 5.0 are the only supported virtualization hypervisors. Any 
other hardware platform or VMware hypervisor will be supported on a “Best Effort” basis: we will try 
to help you, but it may not be possible to reproduce all problems, and we cannot guarantee a solution. 
No other virtualization hypervisor is supported. 

Cisco recommends that the server hosting your virtual appliances have a minimum requirement of two 
64-bit x86 processors of at least 1.5 GHz each, 8 GB of physical RAM, and a 10k RPM SAS hard drive 
disk.

VMware ESXi version 4.x comes with a file system that has a default block-size of 4 MB, which supports 
a virtual disk image of up to 1 TB. However, the larger Cisco virtual security appliances (e.g., C600V) 
require more than 1 TB of disk space. In order to run these models, you will need to create a new 
datastore and format it with an 8 MB or larger block size. 

For information on block size and instructions on how to create a new datastore, seeVMware’s technical 
documentation at 

Features on AsyncOS 8.0.1 for Email are supported by AsyncOS for Cisco Content Security 
Management version 8.1.0 and 8.1.1. 

Compatibility of this release with AsyncOS for Cisco Content Security Management releases is detailed 
in the Compatibility Matrix available from 

. 

Note that there is no virtual Cisco Content Security Management appliance at this time.
