Network Adapter - VMXNET3 or E1000?

TMADOCTHOMAS — Wed, 04 Jun 2025 10:02:04 GMT

Hello,

I am trying to deploy OnTAP Simulator 9.9.1 in vCenter 6.7U3. By default, all four NICs use the E1000 adapter type. Is there any harm in deleting the NICs and re-adding them with VMXNET3 before the first boot?

Related question: does it matter which VLAN you attach to the two "internal network" NICs, which I assume is the cluster network? Since it's internal traffic only I'm thinking I could use the storage management network or something like that.

E1000 adapter type is a requirement in Ontap VSIM.

It's got to be more complicated than that :). Just kidding, thank you for the straightforward answer @jcolonfzenpr !

There are ways to automate the installation of the ONTAP simulator. You can take a look at this project:

Nice! Thanks @jcolonfzenpr ! Unfortunately I don't know how to work my way around GitHub, or the language used in this script, but it looks very useful!
