Hi Carl, I'm confused here, in the previous email it was said *And for ESS, it is licensed Per Drive with different prices for HDDs and SSDs.*
But then you mentioned in below email that: But new customers and new OEM systems are *all licensed by Capacity. This also applies to IBM's own ESS*: you can keep upgrading your old (if hardware is supported) gen 1 ESS on Sockets, but if you replace it with *a new ESS, that will come with capacity licenses*. Now the question, ESS is license per Drive or by capacity? .On Fri, Apr 17, 2020 at 4:25 AM Carl Zetie - [email protected] < [email protected]> wrote: > > From my understanding existing customers from DDN, Lenovo, etc. that > have v4 with socket based licenses > >are not entitled v5 licenses socket licenses.
