QLogic Corporation is a manufacturer of networking server and storage networking connectivity and application acceleration solutions, based in Aliso Viejo, California.[2] The company provides virtualized, converged, and cloud environment solutions. QLogic’s products include Fibre Channel Adapters, converged network adapter for the Fibre Channel over Ethernet (FCoE) market, Ethernet adapters, iSCSI adapters, and ASICs. QLogic is a NASDAQ Global Select company (NASDAQ symbol: QLGC).


QLogic was created in 1992 after being spun off by Emulex; the two are now competitors for the Fibre Channel HBA market. QLogic's original business was disk controllers. This business was sold to Marvell in 2005. QLogic went public in 1994 and is traded on NASDAQ under the symbol QLGC.

QLogic has acquired many companies over the years including Ancor, Little Mountain Group, PathScale, SilverStorm and NetXen. To date,[when?] the company has achieved 75 consecutive quarters of profitability.[citation needed] It has shipped more than 15 million Fibre Channel ports.[citation needed]

QLogic was led by chairman H.K. Desai[3] from 1996 until his death in June 2014.[4] Jean Hu is the acting CEO.[5]

QLogic was acquired by Cavium on June 2016.[6]
