<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">>Now the question, ESS is license per Drive or by capacity?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">I apologize for the confusion. Within IBM Storage when we say “capacity” licensing we use that as an umbrella term for both Per TB/PB *or* Per Drive (HDD or SSD). This is contrasted
with “processor” metrics including Socket and the even older PVU licensing.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">And yes, we IBMers should be more careful about our tendency to use terminology that nobody else in the world does. (Don’t get me started on terabyte versus tebibyte…).

<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">So, for the sake of completeness and for anybody reviewing the thread in the future:<o:p></o:p></span></p>

out the number of physical drives is infeasible.**<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">You can if you wish license ESS with Per TB/PB, for example if you want to have a single pool of licensing across an
environment that mixes software-defined, ESS, or public cloud; or if you want to include your ESS licenses in an ELA. This is almost always more expensive than Per Drive, but some customers are willing to pay for the privilege of the flexibility.

<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif">*(In some cases the customer may not even know it because the OEM solution is sold as a whole with a bottom line price, and the customer does not see a line item price for Scale.
In at least one case, the vertical market solution doesn’t even expose the fact that the storage is provided by Scale.)<o:p></o:p></span></p>
