Deploy an Open vStorage cluster with Ansible

At Open vStorage we build large Open vStorage clusters for customers. To prevent errors and cut-down the deployment time we don’t set up these clusters manually but we automate the deployment through Ansible, a free software platform for configuring and managing IT environments. Before we dive into the Ansible code, let’s first have a look at the architecture of these large clusters. For large setups we take the converged (HyperScale as we call it) approach and split up storage and compute in order to scale compute and storage independently. From experience we have…Read more …

2015, the Open vStorage predictions

The end of 2014 is near so it is time to look forward and see what 2015 will have to offer. Some people say there's no point in making predictions and that it's not worth speculating because nothing is set in stone and things change all the time in storage land. Allow us to prove these people wrong by sharing our 2015 storage predictions*: Acceleration of (hyper-)converged platforms Converged platforms are here to stay. Converged solutions are even the fastest growing segment for large storage vendors. But it will be players like Open…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 …
