Is there a limited number of active user sessions? I identified a limit of round about 100 active sessions. If that's the default limit, is there a way to increase this number?
I'm using VC 2.0.1.
I'm referring to the number of users that can be connected to a VirtualCenter, shown in the VIClient under Admin->Sessions.
I'm using the vi perl toolkit to build a web application that allows users to connect to a VirtualCenter and interact with their Virtual Machines. They have to login at the beginning and a session is used to keep the connection to the VC. I created a script with to spawn Vim::login as many times as possible and there does seem to be a default limit of round about 100 Active Sessions per VC.
That's a serious amount of users accessing VC directly.
According to the docs, it's only supposed to scale to 50 concurrent connections if using high spec CPU & RAM.
Do you find the performance suffers?
Also, if each user opens a console session to their guest VM, the overhead on the ESX server is higher.
It's best to have them access a VM using RDP (Windows).
Most of the users will only retrieve some information about their VMs and start some simple operations like powering on a VM. Opening a console will also be possible, but it won't happen very often.
Our VirtualCenter has 4 GB of RAM and it seems that there are 100 concurrent sessions possible. Will there be more concurrent sessions possible if I increase the RAM?
I haven't found this information in the documentation. Can you give me a hint where to find it?
