Craig Nunes, HP Storage, with John Furrier and Dave Vellante at HP Discover Las Vegas 2014 @thecube #hpdiscover Software-defined storage (SDS) is currently one of the hottest interests for today’s IT market, with ample uptake opportunity in the small to medium business (SMB) arena. At HP Discover in Las Vegas this month, Craig Nunes, VP of Marketing & Alliance for HP Storage, sat down with John Furrier and Dave Vellante in an interview for theCUBE to discuss how the game has changed for SMBs buying storage and why resiliency is so essential. Software-defined Storage “is like firing up a VM” Nunes said that, generally, if SMBs have a virtualization environment, they know that they have to “get into shared, resilient storage to get their environment off the ground,” which is precisely what SDS is. “Software-defined storage is shared, resilient storage without buying shared, resilient storage,” Nunes explained. He went on to say that SDS is a low-cost, hassle-free converged infrastructure in a box that’s easy to manage, making it an ideal solution for small environments. In terms of procuring, deploying and configuring storage, Nunes said that SDS “is like firing up a VM.” A Mix and Match of Use Cases Furrier brought up a few varied use cases for storage, like not needing low latency when you want to have a good cost per gigabyte situation and rolling into structured databases for transactions. He said that mix and match use cases like these, which are normally seen in larger enterprises, are now coming down into the medium-sized enterprises. Furrier asked Nunes what this means for customers. Nunes responded, saying generally small or medium-sized enterprises fundamentally desire what is being run in the larger enterprises, but need to find a way to fit that into a tighter budget. Small enterprises may consider a cost-effective SDS approach, while high-growth businesses may look in to accelerating out of SDS and onto an SDS on an appliance or even consider handling a second site. The Importance of Resiliency Nunes explained that “resilience is having the capability within a platform to handle anything that might go wrong and still serve the application with performance customers need.” Giving an example of non-resilience, he said that if you have dual controller arrays and the worst happens in the event that you lose one, the impact of that to the application would result in a 70 percent or 80 percent drop in performance, ultimately killing any business application. When resiliency is put into play, the application will still run with the bulk of its performance, even with the loss of a controller. “You can only get to that if you’ve got a controller architecture that goes beyond the dual controller limitations which is exactly what converged storage is built on,” said Nunes.
