Re: ESRS Gateway and Policy Manager
I talked to EMC presales and he said you were planning the install now and there was an EMC PM already engaged. So your best point of contact is the PM and he can pull in whatever resources are required to help you here. The PM can escalate to me if he needs help, but I think the recommendation I made earlier is the best option for you. EMC will install this for you, so you only have to provide a server or VM built for each GW and the Policy Manager (if you have one), open the specific ports for communication and EMC will do the rest.
If you have any issues at all feel free to get back to me, but the PM should be able to get this sorted for you.
