Samsung Electronics announced on Monday that it acquired Proximal Data, Inc., a San Diego, California-based company that develops server-side caching software with I/O intelligence that work within virtualized systems. The acquisition adds server storage expertise to Samsung's future SSD solutions.

"We are delighted to have Proximal Data join us, which will enable us to enhance our competence in SSD-based software for server systems," said Bob Brennan, Senior Vice President of the Memory R&D Team at Samsung Semiconductor, Inc. "With this acquisition, we will be able to further expand our SSD business in the server and data center markets, while continuing to provide the most advanced SSD solutions to customers."

Caching software improves storage performance by controlling and storing frequently used data more efficiently. Proximal Data holds core technology in the caching software area and has been marketing AutoCache software, a virtual cache storage solution that increases virtual machine density and performance by eliminating I/O bottlenecks, without disrupting IT operations.

The Proximal Data move follows Samsung’s acquisition of NVELO in 2012, a US-based SSD caching software creator. Samsung has applied NVELO’s caching software to its branded SSDs since 2013.
