The primary function of the QLogic 4000 series of Internet Small Computer Systems Interface (iSCSI) Host Bust Adapters (HBAs) is to provide Storage Area Network (SAN) connectivity over Ethernet and Transmission Control Protocol (TCP)/ Internet Protocol (IP) network architectures. Both the iSCSI and TCP/IP processing functions are completely offloaded onto the QLogic 4000 series HBAs instead of being performed on the host server’s Central Processing Unit (CPU). By offloading these processing functions, the host server CPU is able to save processing power. Since QLogic 4000 series adapters are saving the host server CPU processing power, more processing power is made available for server applications, which enhances the overall SAN performance. The combination of complete offloading of TCP/IP traffic, as well as exceptional performance for iSCSI storage traffic makes the QLogic 4000 series an excellent choice for enterprise data centers looking to fill not only the demands of today, but tomorrow’s as well. 

Another way that QLogic 4000 series iSCSI adapters are ready for the future include their support of IP version 6, which allows IT administrators to not only begin building the iSCSI SANs they’ll need for the future, but also to meet a new government installation requirement. And to better meet specific requirements, the QLogic 4000 series of iSCSI adapters offers a wide selection of models, including single port models such as QLA4050, QLA4050C, and QLE4060C, and dual port models such as QLA4052C and QLE4062C, to provide your data center with several possible options. Some of the many advantageous features of the models within the QLogic 4000 series include high reliability, with iSCSI digest support, as well as advanced functionality, with support for jumbo frames, 802: 1Q Virtual Local Area Network (VLAN) Ethernet networking, 802: 3x flow control and more. Other beneficial features of QLogic 4000 series adapters include support for both PCI-E and PCI-X, auto-negotiation capabilities for 100/1000 Megabits per second (Mbps) line rates depending on the device the adapter is attached to, and universal boot support, which allows for remote storage boot implementation.
