ASA Clustering

MKH — Tue, 12 Mar 2019 09:48:47 GMT

Hello

Does the ASA 5555-X support 2-unit clusters, only? Can I cluster 4-unit by purchase license (onother from base license)?

Thank you.

Hi,

Yes you can setup cluster on this model.

The ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X now support 2-unit clusters. Clustering for 2 units is enabled by default in the base license; for the ASA 5512-X, you need the Security Plus license.

With ASA 5555-X appliances you are limited to a 2-unit cluster.

If you need higher throughput (and don't have ASA 5585-Xs), you would generally be better served by something like the Firepower 4100 series.
