For the ASA 5510 through 5550, you might need to upgrade the internal flash memory to 512 MB or add external flash memory if you load multiple 
images of the AnyConnect client along with one or more images of the ASA software, ASDM, client/server plugins, or Cisco Secure Desktop. In 
particular, you might need to upgrade for multiple AnyConnect 3.0 and higher clients with optional modules. The ASA 5505 does not have a flash memory 
upgrade available.

The default internal flash memory for some models was 64 MB in the past; if you have one of these early units, we recommend upgrading your flash 
memory to at least the new shipping default.

3.

For the ASA 5505, only the Unlimited Hosts license and the Security Plus license with failover enabled require 512 MB; other licenses can use 256 MB.
