This guarantee basically stated that running VMware on NetApp would reduce one’s storage requirements by half and if we did not, the remaining storage was on us. At the time these storage savings were powered by our block-level data […]
Data Deduplication and Data Compression in Data Ontap
Last week I published the post ‘Data Compression, Deduplication, & Single Instance Storage’ as a means to raise awareness around these different types of storage savings technologies and to provide some guidance as where each is best suited to be deployed. I’d like to thank all that chimed in to share their thoughts and knowledge […]
Data Compression, Deduplication, & Single Instance Storage
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 […]
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 […]
Transparent Storage Cache Sharing– Part 1: An Introduction

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 […]
