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?
Storage arrays are big, expensive, and difficult to manage. Plus, concentrating storage in a single device puts everything at risk if there is an outage. So why buy a storage array at all? Arrays do a few things very well, and this often makes up for the difference, on balance. Storage Arrays Accelerate Performance One of the most important advancements in data storage in … [Read more...] about Storage Arrays Do A Few Things Very Well
The time has come to take sides on the core question of storage for virtual servers: Do you want storage intelligence to live in the hypervisor or the array? Most administrators are already lining up on one side or the other, unintentionally casting their vote while the rest flounder. But the storage industry must wake up and embrace the divide. Hypervisor Huggers … [Read more...] about Are You a Hypervisor Hugger or a Storage Stalwart?
VMware’s introduced the “vStorage APIs for Array Integration” (VAAI) in vSphere 4.1, and block-heads like me went nuts. We’ve been trying to integrate storage and servers for decades, and VMware’s APIs finally allowed this to work in truly seamless fashion. But the world of VAAI is a thicket of bizarre naming and puzzling functionality. Some VAAI primitives are ignored or even … [Read more...] about A Complete List of VMware VAAI Primitives
