Before you read this, check out Today’s Storage: Same As It Ever Was for a bit of background... For the past few decades, some of the best minds in computer science have been drawn to the question of storage. How can data be better protected, shared, and exploited? Given the price and performance profiles of various storage devices, how can we maximize benefit for a given … [Read more...] about Waves of Storage Innovation
Data storage has always been one of the most conservative areas of enterprise IT. There is little tolerance for risk, and rightly so: Storage is persistent, long-lived, and must be absolutely reliable. Lose a server or network switch and there is the potential for service disruption or transient data corruption, but lose a storage array (and thus the data on it) and there can … [Read more...] about Today’s Storage: Same As It Ever Was
Hard disk drives keep getting bigger, meaning capacity just keeps getting cheaper. But storage capacity is like money: The more you have, the more you use. And this growth in capacity means that data is at risk from a very old nemesis: Unrecoverable Read Errors (URE). Let's get one thing out of the way from the start: The only thing protecting your data from corruption … [Read more...] about Why Big Disk Drives Require Data Integrity Checking
This year for my Truth in IT seminars, I’m shifting away from virtualization to focus on enterprise storage once again. But this won’t be any ordinary “storage 101” seminar. Rather than trying to talk about every element, I’m focused on what’s new! Next-generation storage technologies are here, from the smallest startups to the established players. For 2014, I’ll focus … [Read more...] about Truth in Storage: The Next Generation – Announcing My 2014 Seminar Series
Virtualization is a disruptive technology in every sense of the word. By abstracting and simplifying physical resources, virtualization enables dynamic utilization. But this “translation” from physical to virtual disrupts the assumptions that enable performance and flexibility of physical devices such as storage arrays. Your Assumption Is Invalid See Storage Arrays Do A … [Read more...] about The I/O Blender Part 2: What Does Virtualization Do?
