NetApp, Inc. (NASDAQ: NTAP) earlier this week announced it has completed its $870 million acquisition of Boulder flash storage maker SolidFire.

The deal has closed two months ahead of projections. The Sunnyvale, Calif.-based company announced its intention to buy SolidFire in December. At the time, the all-cash deal was expected to close in April.

SolidFire was founded in 2010 by CEO David Wright, who moved the company to Boulder the following year. In August, SolidFire announced it would be tripling in size and moving to a 62,000-square-foot office at the PearlWest development at 11th and Pearl streets, former site of the Daily Camera.

SolidFire employs about 250 people in Boulder.
