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
Storage interconnects are about to be revolutionized, and virtualization is the driving force. Traditional SAN and NAS has been augmented with technologies like VAAI to work with the “I/O Blender” presented by the hypervisor, but this is just the first step. Next comes distributed and converged storage technologies like VSAN. But this opens the doors to new I/O technologies … [Read more...] about #VMEspresso with @SolarWinds at #VMworld: “Storage I/O is About to Get Crazy”
VMware is in an enviable but tricky situation: The company must work closely with hardware partners, keeping these prime sales and promotional channels happy and supportive. But VMware must also innovate around proprietary OEMs, subverting their products with integrated software before a rival steps up with an integrated alternative. This two-prong "coopetition" strategy has … [Read more...] about VMware’s Hardware Partner Strategy: Heads I Win, Tales You Lose
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
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?
