ASA 5545x Processor question

[Craddockc]

Community,

When I do a show version | i Hardware on my ASA it returns the following:

qts-fwnonprod-1a# show version | i Hardware
Hardware: ASA5545, 12288 MB RAM, CPU Lynnfield 2660 MHz, 1 CPU (8 cores)

However, on the Home page of the ASDM, when I click on the "Core Usage" tab it only shows the Core1 usage. Why is the ASDM not showing all cores? Ive attached a PNG for reference. Thanks.

This is normal behavior. The remaining cores (and also 6GB of RAM) is reserved for the Firepower security-module that you could install on the box.

Karsten,

So 1 Core is dedicated to the ASA while the other 7 are dedicated to the Firepower module? We are running Firepower on the box. Thanks.

The more I think about it, I remember that there are 6 cores visible inside of FP on the 5545-x. You can look at it at the FP-cli with „show cpu“ or with „lscpu“ in expert mode. At least, most cores belong to Firepower and the ASA itself only has limited resources.
