Episode notes

Brian invited Peter Skovrup, VP of Product Management for Pure Storage, to continue their conversation from the Pure //Accelerate Las Vegas event in June. Brian and Jordan spent a few days with Pure, learning the latest for what’s new with Pure Storage technology – like their 150TB flash module!

<span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span>This is another live event where the audience gets to ask Brian’s guests questions as they arise throughout the conversation. In case you missed it, our first two live events had a few hiccups, but we seem to have ironed those out now. This jam-packed session covers hardware and software, the all-important NPS scores, flash technology, and how it all fits together with Pure Storage solutions.

This is an exciting conversation that also tends to be a learning experience. If you have the time, it is worth listening to this entire podcast. However, if you are short of time or need to find details on a particular topic, we have created an easy way to jump around the podcast to get to the issues that are most interesting to you.
