Is VSA the future of software-defined storage?

HP on software-defined storage: why VSA is the future   In my last post, I posed a question: How do you define software-defined storage? I offered up a base definition of what software-defined storage means to HP. Since then IDC has released a new taxonomy on software-defined storage which includes this definition:   IDC defines software-based storage as any storage software stack that can be installed on any commodity resources (x86 hardware, hypervisors, or cloud) and/or off-the-shelf computing hardware...

RE: Is VSA the future of Software Defined Storage? (OpenIO)

I was reading this article on the HP blog about the future of Software Defined Storage and how the VSA fits perfectly. Although I agree that a VSA (virtual storage appliance) could potentially be a Software Defined Storage solution I do not really agree with IDC quote used for the basis of this article and on top of that I think some crucial factors are left out. Lets start with the IDC quote: IDC defines software-based storage as any storage software stack that can be installed on any commodity resources (x86 hardware,... [Lire la suite]

HA enhancements, exploring the next version of ESX/vCenter

Let’s start with a screenshot: These are the properties of an HA cluster, as you can see there are two sections that changed: “Enable Host Monitoring” is a brand new feature. Anyone who did network maintenance while HA was enabled knows why this feature will come in handy. Those that didn’t: Isolation response! If ESX is unable to send or receive it’s heartbeat and can’t ping it’s default isolation response address it will shutdown all VM’s. To avoid this behavior you can switch of HA for a specific host with this new... [Lire la suite]
