Where should i install the plugin in vcenter server or my local machine wher vshphere client is installed.

what exactly are you struggling with ?

VAAI is built-in into the array, you don't need to install anything.

So Installing VSI plugin should be everything right ? and does it require any downtime ?

ESX tells VNX to offload certain functionality.

you install on the system where you run vSphere client

Do we need to have a licence to install this ?

Can you see the below link and confirm ?

no downtime is needed.

Also this can be reffered : https://support.emc.com/docu31107_EMC-VSI-for-VMware-vSphere:-Unified-Storage-Management--5.0-Product-Guide.pdf?language=en_US

for further queries.

Thanks

Rupal thanks for the info.. but if i need VAAi plugin feature for vcenter what is the plugin i need to install ?

So when we vMotoin the lun's the performace will be impacted on the array right not on the vcenter ???

No it does not require a License.

If you still have the access to powerlink then you can go ahead installing the VSI the same way.

Thanks

Thanks for the info.... i guess installing VSI is pretty straight forward.. i guess this should server my purpose of VAAI...

take a look at relatively new NFS plug-in for VNX
