In Section 3.3.3, page 43, Enabling or Disabling AMD, it is wrongly mentioned that to activate AMD the mem_dedup should be set as '0', it should be '1' instead.

To enable AMD, use the chhwres command:
chhwres -r mempool -m <managed system> -o s -a "mem_dedup=0" --> mentioned wrongly as '0'

A new draft with this correction will be online in about 2 hours. Thanks for spotting this!

Hi.

On page 22 we can see screenshot of ASM. According to this picture you use 8233-E8B with AL740_042 firmware. But I cant find this firmware for this server. Can you help to find this firmware?

Mr. Patrushev, you have very good eyes. Because of the timing of the project, we used a development test mule server that operated like a "C" model. The image has been updated (figure 3-5 and 3-6) to show a C model

Now that the paper is out of edit, I have updated the hardware requirements table to reflect the specific models at the time of writing.
