Infinio is a small startup that provides a server-side I/O optimization layer that brings storage performance closer to applications without requiring new hardware. It uses a globally deduplicated read cache across an ESXi cluster's aggregated RAM to improve latency by 10x and reduce reads from storage by 65-85%. Infinio was founded in 2011 and is headquartered in Cambridge, MA. It has raised $24 million in funding and competes with companies like Quantum, StorMagic, and PernixData in the I/O optimization market.
