Pivot3 was founded in 2003 on the idea that today's stack of virtual servers, shared storage and networks could be radically simplified and unified through software innovation to dramatically increase scale-out performance while driving down complexity and cost. The founders of Pivot3 applied their virtualization and storage RAID expertise to develop the patented vSTAC (Virtual Storage and Compute) operating system that runs on x86 commodity hardware and embeds server virtualization deep into the shared storage layer.
