How many Nitro devices can we add to a single ESM system. Are there any limit in number for each device type, e.g. 16 for Receivers, 4 for ELM.
Is it model dependent? If it is, could you provide devices number for ETM-5600.
I can't find information for this question in knowledge base. Really sorry if it's already there.
QA has seen some limits upwards of 255 devices but the the general rule is as long as your total devices event rates are not exceeding your limits of your ESM then you can have as many as you want/need.
From the Mcafee website:
|Collection Rates||300,000 events per second1||150,000 events per second1||70,000 events per second1||50,000 events per second1|
|Analytical Performance||Less than 10 seconds2||Less than 30 seconds2||Less than 1 minute2||Less than 3 minutes2|
|Local Storage||14 TB3 + 3.2 TB Flash||14 TB3 + 800 GB SSD||14 TB3||8 TB3|
For example, if I got ETM-5600 and I want to add 8 of ERC-1250.
ETM-5600 can handle 50,000 EPS.
ERC-1250 can handle 5,000 EPS. 8 of ERC-1250 will be 40,000 EPS in total.
So in above case, it would be fine since EPS is still not overwhelm ESM, correct?
Thank you very much for information.
Theoretically that should work. But those numbers are in ideal conditions. Out of sync data and correlation can cause the system to perform differently. In most situations yes you will be fine but as a note those are ideal situational numbers.
