  • Question

  • Hello,

    i have an ata-center hosted in ESXi host, and it use 1 adapter physical with more virtual machine other, and i have more than 7 domain controllers server have installed ata lightweight gateway. I wonder to ask about problem traffic send from DC to ATA Center? it can be very big to affected network perfomance of other VM hosted in same ESXi host, in my situation, shoud i deploy more ATA center( i don't know how, i just had 1 forest, if can, can provide me how), or other workaround.

    thank you very much.

  • The easiest way to measure it is to use the ATA sizing tool. Read this: https://docs.microsoft.com/en-us/advanced-threat-analytics/plan-design/ata-capacity-planning 

    Basically it is a script that measures the DC for 24 hours and creates an excel spreadsheet. From this spreadsheet you can see in the table in Ata Capacity planning on how much it can take....

    From my experience an ESXi host should have more than one phyiscal nic when hosting a lot of vm's. 2-4 nics with 1gb link on each.

  • The estimated bandwidth between the ATA Gateway (or lightweight gateway) to the ATA Center is about 1-2% of the traffic being analyzed (i.e. about 98% of the traffic is being filtered before sent to the center). Hope that is what you are looking for.
