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 …

White Paper: Turning Object Storage into Virtual Machine Storage

In this White Paper "Turning Object Storage into Virtual Machine Storage" we discuss Object Storage as storage solution for Virtual Machines. Due to technical hurdles it is impossible to run Virtual Machines directly from an Object Store. The main issues are eventual consistency, performance and latency and different management paradigms. A distributed file system is also no fit for the job. To turn Object Storage into primary storage for hypervisors, the solution must be especially designed for Virtual Machines and take a radical different approach compared to existing storage technologies. Open vStorage takes…Read more …

Open vStorage 1.0.3 Beta

We couldn't wait until the end of April before pushing out our next release. That is why the Open vStorage Team decided to release today (April 17 2014) a small version with following set of features: Remove a vPool through the GUI: in version 1.0.2 it was already possible to create a vPool and extend the vPool across Hosts through the GUI. To make the whole vPool management process complete and more user friendly, we have added the option to remove a vPool from a Host. This is of course only possible in…Read more …

Why both converged storage and external storage make sense

Today the peace in storageland has been disturbed by a post of Storage Swiss, The Problems With Server-Side Storage, Like VSAN. In this post they highlight the problems with VSAN. At the same time Coho Data, developer of flash-tuned scale-out storage appliances, released a post about why converged storage, such as VSAN, only seems to be usefull in a niche area. You can read the full post here. VMware had to respond these "attacks" and released a post countering the problems raised by Storage Swiss. As with every black-and-white story both sides have…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 …

Upcoming release (End April)

The Open vStorage tries to release a new version once month. Since version 1.0.2 was released end of March, the next (big) release release can be expected by the end of April. This release, Open vStorage 1.1 is planned to have following content: HA Support: in version 1.0.2 you need to set a host offline to be able to steal volumes away from the VSA on that host. In the next release we would allow to steal volumes automatically when a host is down. This means that Virtual Machines which are migrated by…Read more …

Open vStorage 1.0.2 Beta

KVM Open vStorage supports KVM as Hypervisor. Swift Support Open vStorage supports Swift (SAIO - Swift All In One, Swiftstack, ...) as Storage Backend. Configuration of a vPool through the GUI You can now add a new vPool through the GUI to a VSA. In case the vPool is a not a local filesystem, you can also stretch it across multiple VSAs. Protection against moving a vDisk to a VSA where it can't be served Each VSA can only serve only a limited amount of vDisks. In case a vDisk is moved between…Read more …

Software for the hybrid cloud future

The demand for data storage shows no sign of slowing down. According to IDC, in 2012, external disk storage capacity rose 27 percent over the previous year to reach over 20 exabytes worth a staggering $24 billion in annual spending. Media and entertainment as well as web based services are consuming vast quantities of data storage and the arrival of big data analytics is accelerating the growth further. But quantity of storage is simply not enough, especially as organisations increasingly need to share data or make it available for inspection by third parties…Read more …
