Concurrent connection on vSphere

Hi guy,

Have anybody known that ESXi and each VM running inside have limitation of concurrent connection?

Do you know there is a concurrent connection limitation on x86 server, or ESXi Port, or vStandard Switch port, or vDistributed Switch port in VMware?

I want to run one app in VM that relate to transaction per second, that why i have to make sure on concurrent connection that limited on x86 server or VMware.

if you guy know or have experience, please help to share.

any of your comment is valuable.

Thank you for your any comment.

Apart from this limitation, you should think about Resource limitation on virtual machine for both CPU and memory can impact to your application.

Hi DavoudTeimouriDavoudTeimouri,

what i am worrying about is concurrent connection limitation on vDSW or vSSW port.

The VM are using a port from one vDSW or vSSW to connect to outside. so there might be many connection access to that VM if my VM running any kind of transaction service.

example, if vDSW or vSSW support only 100k concurrent connection, so if i have transaction 100k + 1 + 2 + 3 ... it is a problem.

why i am looking for like that. even Physical device like CISCO ASA still have concurrent connection, and CISCO switch limited by Through put.

so i don't think VMware vDSW or vSSW don't have limitation on connection.

I did try to research on many website, but i still not find the answer yet

Thank you for your sharing IDEA.

Dear Vivath, have you got the answer for this topic?

I need this information as well since I got trouble when one of VM runs IDM and made hundreds of concurrent connection to download many files at the same time. I don't want to limit the bandwidth, but do really want to know if its possible to limit "concurrent connection" using ESXi.

I have read the manual given (https://www.vmware.com/pdf/vsphere6/r60/vsphere-60-configuration-maximums.pdf ), but it only said about: "Concurrent remote console connections to a virtual machine". I am not native English speaker and its possible that i missed something which is already there. It would be great if anyone can be kind to let me know where is it in the subject.

I do really really appreciate if anyone can help me out in this matter Smiley Sad

Thank you so much

That kind of feature is not available in vSphere I reckon.

But you should be able to get the feature that you are looking for from third party products.

In google, search for "bandwidth controller" or "bandwidth manager"

Most bandwidth controller/manager can limit per IP or per user.

If you are looking for non-english subforum, VMTN actually have a foreign language forum in multiple languages. See this link VMTN Forums by Language
