Today I wrapped up several weeks of travel which included the Charlotte VMUG conference, NetApp's Foresight engineering event, and a number of customer and technical partner meetings. During these travels a small number of individuals would use the term data deduplication as any technology which reduces the amount of storage capacity required to store a data object (file, LUN, … [Read more...] about Data Compression, Deduplication, & Single Instance Storage

Transparent Storage Cache Sharing– Part 2: More Use Cases
In part one of this series I introduced you to Transparent Storage Cache Sharing and introduced the use case of serving virtual machines and their binaries. The post received some great feedback and allowed me to realize that I wasn’t as clear as I had hoped to be in beginning this conversation. Before we continue the conversation by looking at additional use cases, I think I … [Read more...] about Transparent Storage Cache Sharing– Part 2: More Use Cases
Transparent Storage Cache Sharing– Part 1: An Introduction
I expect most of my readers are familiar with Transparent Page Sharing (TPS). For those in need of a refresh, TPS increases the over all performance capabilities of an ESX/ESXi cluster by ensuring efficient use of server memory. The TPS process achieves this efficiency by eliminating redundant virtual machine memory pages by remapping any duplicate reference back to a single … [Read more...] about Transparent Storage Cache Sharing– Part 1: An Introduction
SPEC SFS2008 Verifies You Can Run Faster on Fewer Disks with PAM
NetApp is the only storage vendor focused on reducing storage hardware footprints. Evidently discussions surrounding the use of storage saving technologies in a production environment must be upsetting to the traditional storage array manufactures as anytime I discuss the technologies that enable such environments the comments sections of my posts inevitably end up reading (and … [Read more...] about SPEC SFS2008 Verifies You Can Run Faster on Fewer Disks with PAM
Run Everything Virtualized and Deduplicated : aka Chuck Anti-FUD
Last night I got caught in what I would classify as a tweet-fight with several of my chums over at EMC on the role storage arrays play within a virtual datacenter. The conversation was pretty intense and at one point I posted the following string of tweets… @sakacc @chuckhollis – Guys EMC & NetApp just look at virtualization differently. Allow me to explain… @sakacc … [Read more...] about Run Everything Virtualized and Deduplicated : aka Chuck Anti-FUD
