US-based flash storage provider Tegile Systems closed a $70m series D round on Wednesday backed by computer hard disk drive manufacturer Western Digital and flash memory storage company SanDisk.
Meritech Capital Partners, August Capital, Capricorn Investment Group, Cross Creek Advisors and Pine River Capital Management also contributed to the round.
Tegile has developed flash storage technology for enterprises called IntelliFlash, which can deduplicate files on drives and compresses data in order to increase capacity.
The company has raised $117.5m to date, with SanDisk and Western Digital previously backing a $35m series C round in 2013 that was led by Meritech and also featured August Capital. August had already invested $10m in Tegile in 2012.
According to regulatory filings, Tegile secured $2.5m in a 2010 series A round and received $740,000 in debt financing in 2013.
Tegile will use the series D funding to support its global expansion, focusing particularly on Europe and Asia over the next 18 months. The company also hopes to build out its reseller network and double its staff from a current 300.
