What is the big deal with Virtual Volumes, VMware?

June 30 2014, mark the date, people. This is the day when VMware announced their public beta of Virtual Volumes. Virtual Volumes, or VVOL as VMware likes to call them, put a Virtual Machine and its disks, rather than a LUN, into the storage management spotlight. Through a specific API, vSphere APIs for Storage Awareness (VASA), your storage array becomes aware of Virtual Machines and their Virtual Disks. VASA allows to offload certain Virtual Machine operations such as snapshotting and cloning to the (physical) storage array. Now, what is the big deal with…Read more …

A distribution center for Virtual Machine data

At open vStorage we quite often get the question: “Ok, you are a Grid Storage Router but what is that exactly?” To explain what a Grid Storage Router is and why it is essential in a virtual environment, I’d like to make the analogy with Walmart, the largest retailer in the world. You can compare Open vStorage to the grid of distribution centers of Walmart. Walmart has 42 regional U.S. distribution centers with over 1 million square feet. In total these distribution centers have more than 12 miles of conveyor belts to move…Read more …

VM-Centric Storage

We’ve designed Open vStorage to be VM-centric and a lot of the features we create over the next few months will leverage the VM-centric architecture. The idea of VM-centric storage has been implemented by new age storage companies such as Tintri, VMware (with vSAN) and us when designing our products.This approach is a huge departure from the “traditional” LUN based approach taken by SAN vendors. This brings the question – “What exactly do we mean by VM-centric architecture?”. Managing VMs and not storage The key feature with VM-centric storage is that IT administrators…Read more …
