Violin Memory’s sale to Quantum Partners ends a turbulent few years for the company, which held an initial public offering in 2013 but struggled to make money. In December, the company filed for Chapter 11 bankruptcy, which allowed it to stay in business while it looked for a buyer.
Violin Memory was among the first business technology companies to sell flash storage, which is faster and more efficient than traditional spinning disc storage. However, several big rivals like Hewlett Packard Enterprise hpe and EMC, which is owned by Dell Technologies, later moved into the market and made it difficult for Violin Memory to compete.
