Infinidat’s Solution For the I/O Blender: Math

September 22, 2015 By Stephen 2 Comments

I've talked a lot about the I/O blender in the last decade or so.[1. I've even been told I invented the term!] I've always said that information is the solution, allowing arrays to de-multiplex data. But a new enterprise storage company, Infinidat, claims that they can beat the I/O blender using math. Here's their concept. You should check out my I/O Blender series: History, … [Read more...] about Infinidat’s Solution For the I/O Blender: Math

VMware’s Hardware Partner Strategy: Heads I Win, Tales You Lose

February 11, 2013 By Stephen 1 Comment

The I/O Blender Part 3: Behold the Power of the Demultiplexer

May 25, 2012 By Stephen 3 Comments

Virtualization has disrupted the I/O path, reducing the value of enterprise storage arrays. But all is not lost: An effort is afoot to make things right by increasing communication between hypervisor and array and demultiplexing data before it is stored. “What we have here is a failure to communicate” The core problem with the I/O blender is that virtual machine disk images … [Read more...] about The I/O Blender Part 3: Behold the Power of the Demultiplexer

The I/O Blender Part 2: What Does Virtualization Do?

May 24, 2012 By Stephen 7 Comments

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?
