ASA 9.2(1) and later
VMware vSphere 5.x:
  • ESXi Server
  • vCenter Server
  • vSphere Web Client or vSphere Client for Windows or Linux
See the VMware documentation for more information about vSphere and hardware requirements:
Note: You cannot install the ASAv directly on an ESXi host without using vCenter.
Note: You cannot deploy the ASAv using vCloud Director.

ASA 9.3(2.200) and later

Kernel-based Virtual Machine (KVM):

  • qemu-kvm, libvirt-bin, bridge-utils, virt-manager, genisoimage, virtinst, and virsh tools (part of KVM installation).
  • Linux Ubuntu 14.04 LTS host.

The ASAv has been extensively tested on an Ubuntu 14.04 LTS host, but you can use other Linux distributions.

ASA Memory Information

The ASA includes DRAM (also referred to as DIMM) and internal flash memory. On some models, you can optionally use an external flash memory as well. This section includes the following topics:

Memory Requirements

The following sections list the standard and recommended flash memory and DRAM.

Current Models

See the following guidelines:

  • The ASA 5500-X models can run a software module such as the ASA IPS or ASA CX alongside the ASA firewall and VPN functions. For these models, DRAM is evenly and statically distributed between the Firewall/VPN functionality and the software module functionality, with 50% allocated to each. Memory for the software module is reserved even if you are not running a software module; you cannot use that memory for firewall and VPN functions. For other models with hardware modules, such as the ASA 5585-X, the modules include their own memory, so all of the ASA memory is used for firewall and VPN.

Shipping Memory

See the following guidelines:

  • Note that the shipping DRAM increased after February 2010; the DRAM requirements for 8.3 and higher match the newer default shipping sizes. The newer default shipping DRAM is the current maximum DRAM you can install in your unit. See Memory Kits to order an upgrade kit.
  • ASA 5520s and ASA 5540s manufactured before August 2011 have four DIMM sockets. ASA 5520s and ASA 5540s manufactured after this date have two DIMM sockets. All ASA 5550s have four DIMM sockets.
  • 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.
  • For the ASA 5505 with Version 8.3 through 9.1, only the Unlimited Hosts license and the Security Plus license with failover enabled require 512 MB; other licenses can use 256 MB. For Version 9.2 and later, all ASA 5505 licenses require 512 MB.

Viewing Flash Memory

You can check the size of internal flash and the amount of free flash memory on the ASA by doing the following:

  • ASDM—Choose Tools > File Management. The amounts of total and available flash memory appear on the bottom left in the pane.
  • CLI—In Privileged EXEC mode, enter the dir command. The amounts of total and available flash memory appear on the bottom of the output.

Example:

hostname # dir
Directory of disk0:/

DRAM, Flash Memory, and Failover or ASA Clustering

In a failover or cluster configuration, the units must have the same amount of DRAM. You do not have to have the same amount of flash memory. For more information, see the failover or clustering chapters in the configuration guide.

Note: If you use units with different flash memory sizes, make sure that the units with the smaller flash memory has enough space for the software images and configuration files.
