Skyera announced its first all-flash array, skyHawk, in August 2012. The company shipped skyHawk to a limited number of enterprise customers in 2013 and made the product available in volume in 2014. The skyHawk was noted for its low price per gigabyte, high density, small physical size, and use of custom-built storage blades rather than standard solid-state drives (SSDs). The skyHawk was a single-controller storage system. Skyera had disclosed plans for a dual-controller skyEagle all-flash array, but the ship date was repeatedly delayed. The skyEagle had not shipped at the time of the Western Digital acquisition.
Former executives at SandForce, a flash controller vendor, launched Skyera in 2013. The Skyera executive team raised at least $51.6 million from private investors, including Dell Ventures and Western Digital. Skyera was based in San Jose, Calif.
