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.
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.
As I have done since version 3.5, I’m charting the storage changes in VMware’s latest release of vSphere, 5.1. Unlike version 5, which included many new technical storage features, 5.1 mainly tweaks existing features and adds these new elements to the mix.
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.
Virtualization is a disruptive technology in every sense of the word. By abstracting and simplifying physical resources, virtualization enables dynamic utilization. But this â€œtranslationâ€ from physical to virtual disrupts the assumptions that enable performance and flexibility of physical devices such as storage arrays.
