Dear friends,

I am Satya. I am working in customer support division. Very much interested in storage / cloud field. Done some other brand (non emc) storage installations. I want to shift my career from field support to admin side. Last week i completed EMC ISM (E10-001) exam successfully. Planning to proceed for E20-547 VNX Solution specialist exam for Storage Administrators. Is this a wise decision?? in future want to move in to cloud side. Totally confused which one to proceed next......... Please suggest which certification is advised next?? How should be my career path?? Please help in resolve my dilemma state,.

YOUR VALUABLE SUGGESTIONS ARE HIGHLY INVITED.

Thanks in advance

Satya..
