QLogic Corporation was an American manufacturer of networking server and storage networking connectivity and application acceleration products, based in Aliso Viejo, California through 2016. [2] QLogic's products include Fibre Channel adapters, converged network adapters for Fibre Channel over Ethernet (FCoE), Ethernet network interface controllers, iSCSI adapters, and application-specific integrated circuits (ASICs). It was a public company from 1992 to 2016.
QLogic was created in 1992 after being spun off by Emulex. QLogic's original business was disk controllers. QLogic had its initial public offering in 1994 and was traded on NASDAQ under the symbol QLGC. Originally located in a Costa Mesa, California building adjacent to Emulex, it competed against its parent company in the market for Fibre Channel controllers for storage area networks. [3]
QLogic acquired companies including NetXen. Integrated circuit designer Silicon Design Resources Inc. based in Austin, Texas, was acquired for about $2 million in 1998. [4] In May 2000, QLogic acquired Fibre Channel switch maker Ancor Communications for about $1.7 billion in stock. [5] Little Mountain Group, founded in 1999 and developer of iSCSI technology, was acquired in January 2001 for about $30 million. [6] The compiler company PathScale was acquired for about $109 million in February 2006. [7] Silverstorm Technologies, which designed InfiniBand products, was acquired in October 2006 for about $60 million. [8] After attempting to use PathScale for cluster computing over InfiniBand, the compiler business was sold to SiCortex in August 2006. [9]
QLogic was led by chairman H.K. Desai from 1996, who became executive chairman in 2010 until his death in June 2014. [10] In 2012, the InfiniBand products were sold to Intel for $125 million. [11] Simon Biddiscombe became chief executive in November 2010, until resigning in May 2013 after two years of falling revenue. [12] [1] Prasad Rampalli became chief executive a few months later, until August 2015. Jean Hu became acting CEO again at that time. [13]
QLogic announced it was being acquired by Cavium in June 2016, for about $1 billion over its balance sheet cash. [14] After the deal closed in August 2016, job cuts were announced. [15] It announced it would move to Irvine, California in 2017. [2]
Cavium was acquired by Marvell Technology Group in 2018. [16]

In 2005, QLogic acquired Troika Networks and storage virtualization products. Later in 2009, it acquired NetXen and Intelligent Ethernet Adapter products. In 2014, QLogic signed a broad technology alliance agreement with Brocade Communications Systems and acquired its fibre channel and converged network adapter business.
InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency. It is used for data interconnect both among and within computers. InfiniBand is also used as either a direct or switched interconnect between servers and storage systems, as well as an interconnect between storage systems. It is designed to be scalable and uses a switched fabric network topology. Between 2014 and June 2016, it was the most commonly used interconnect in the TOP500 list of supercomputers.
In computer hardware a host controller, host adapter or host bus adapter (HBA) connects a computer system bus which acts as the host system to other network and storage devices. The terms are primarily used to refer to devices for connecting SCSI, SAS, NVMe, Fibre Channel and SATA devices. Devices for connecting to FireWire, USB and other devices may also be called host controllers or host adapters.

These high-speed data-transport technologies are used in high-performance computing facilities, in research and various industries.
Fibre Channel over Ethernet (FCoE) is a computer network technology that encapsulates Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks while preserving the Fibre Channel protocol. The specification was part of the International Committee for Information Technology Standards T11 FC-BB-5 standard published in 2009. FCoE did not see widespread adoption.
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage. SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage. A SAN typically is a dedicated network of storage devices not accessible through the local area network (LAN).
BladeSystem is a line of blade server machines from Hewlett Packard Enterprise that was introduced in June 2006.
Data center bridging (DCB) is a set of enhancements to the Ethernet local area network communication protocol for use in data center environments, in particular for use with clustering and storage area networks.
The Linux-IOTarget (LIO) is an open-source SCSI target implementation included with the Linux kernel. Internally, LIO does not initiate sessions, but instead provides one or more Logical Unit Numbers (LUNs), waits for SCSI commands from a SCSI initiator, and performs required input/output data transfers. LIO supports common storage fabrics, including FCoE, Fibre Channel, IEEE 1394, iSCSI, iSCSI Extensions for RDMA (iSER), SCSI RDMA Protocol (SRP) and USB. It is included in some Linux distributions and a storage option for cloud deployments due to its native support in QEMU/KVM, libvirt, and OpenStack.
