Anyone have experience With VMWare? I have a few questions , please

hey guys im new to using Virtual Machine and VMware stuff, so I just had a few question. If I plan to be running like a lot of VMs like over 30+ and I suspend each VM after being done using it, will that take a toll on my host PC like my storage or ram or whatever?

Basically these virtual machines are only being used for youtube, to upload videos, and thats only while im using them, when their suspended they will not be doing any thing in the background.

I'm trying to figure out if i should get a external hard drive and a seperate pc or laptop for this, because it may be too much for my host PC?

You will most likely be using quite a bit of storage space, depending on your chosen guest operating system.

Worst case scenario when it comes to RAM or CPU usage while the VMs are powered off, there might be some daemons (background processes) that VMWare is always running just to be ready to power on VMs or check the status of running ones, for example. These aren't anything to worry about, and shouldn't have much, if any, impact on your daily host usage.

yeah the storage space it takes up a lot, the main virtual machine is 10 GB, then every time i clone it , it is 3gb so with 50 virtual machines it will take up like 150-200GB

but im more worried about when the vms are suspended will they still affect my host machine.

Also do you recommend I get an external hard drive, if i plan to have a lot of VMs ? maybe an external hard drive will work and I wont have to get another PC

I think that it would be negligent not to mention that storage, and extending to even more VMs in the future might be cheaper and less stressful for you to manage if you host these VMs on a dedicated server somewhere.

However, if this isn't true, then yes, I would recommend getting external storage. I would suggest getting an external SDD instead of an external HDD so you can boot the VMs faster. If you can prune VMs as well after a time, I would suggest doing that as well.

The key elements to running virtual infrastructure, if running 1 host, is CPU, Memory and Storage.
The VMWare kernel will distribute the resources it has to however many machines you have, typically Memory and Storage being the most sort after by each VM.
As suggested, I would use internal SSD / nVME for the OS drive of each VM. Stick as much memory as you can in the host machine and I would recommend a minimum of 4gb per VM. There are ways to distribute storage and Memory more sparingly. For example, use Thin provisioning for storage, the VM will only consume physical storage as and when it writes to the disk.
There is resource consumption when you suspend a VM, you might be better powering off the VM's if possible.

ok thanks I'll probably get a SDD then.

And I looked up "Virtual Machine Prune" and I couldn't find anything about it. I think it means something to making the virtual machine smaller in size?

So your saying it wont be as good if I use a external SSD instead of internal?

and thanks for the information

I would recommend and internal SSD or maybe even NVME disk
