OpenStack startup ZeroStack is stacking up those Benjamins to the tune of $16 million in a Series B that was announced on Tuesday.

The ZeroStack Cloud Platform is a hyperconverged, on-premises appliance running ZeroStack’s version of OpenStack, which is based on the Kilo release and will soon support the Liberty release. It's designed to let users build out private clouds where compute, storage, networking, and management are converged onto one platform.

ZeroStack's platform can be applied toward functions such as software-defined storage, software-defined networking (SDN), self-healing management, monitoring and analytics, and capacity planning.

The latest round was led by Formation 8 with contributions from existing investor Foundation Capital and a current member of the company's board of directors, Mark Leslie. ZeroStack also says that Shirish Sathaye, general partner at Formation 8, will join its board of directors.

Venture capital funding has been good to OpenStack companies. In August, Intel led a $100 million funding round for Mirantis, which also included an announcement that Intel and Mirantis would collaborate on a cloud platform for enterprises. Mirantis also raised $100 million in a Series B round a year ago.

ZeroStack, which has 25 employees, was founded last year by Kiran Bondalapati, who was a founding engineer at Bromium, and Ajay Gulati, who was a senior architect and a R&D lead at VMware. After publicly launching in August, the Mountain View, California-based company has raised $21.6 million to date.

A spokeswoman says ZeroStack has been deployed with with a major retailer, a company in the life sciences industry, a university, a local municipality, and a company in the software analytics space.
