what is the procedure for Commvault certification?

Hi @Atul 

Please would you clarify the request.

Are you looking become Commvault certified yourself, so as an individual you have Commvault Certified Professional status?

Scroll down to Training section which gives some guidance on where and how to obtain training and certifications.

or

Are you seeking to certify some hardware for use with Commvault?

Thanks,

Stuart
