SANs with Ethernet and IP: iSCSI
IT managers now have a choice when considering SAN management options. The QLE4060C and QLE4062C (collectively referred to as the QLE406xC) iSCSI Host Bus Adapters (HBAs) provide connectivity to SANs over Ethernet and TCP/IP network infrastructures for PCI Express bus-based servers. Using a widely deployed and familiar networking technology, iSCSI can lower the total cost of ownership to better manage and support storage networking.
Networking and Storage Performance
By off-loading the iSCSI and TCP/IP protocol to the adapter, the QLE406xC eliminates the processing, interrupts, and bus accesses required to support protocols in host software. The QLE406xC virtually eliminates the host CPU system processing required for iSCSI and TCP/IP, delivering the equivalent performance of direct attached storage (DAS) and Fibre Channel (FC) SANs.
QLogic is the first to offer IPv6 support in an iSCSI TOE adapter. IPv6 is the next generation of IP addressing, which quadruples the number of network address bits from 32 bits (in IPv4) to 128 bits. As networks migrate to the updated IP protocol, IT managers can be assured that the QLE406xC will interoperate in emerging network environments.
Familiar Storage Functionality
The QLE406xC utilizes the existing storage interface of the operating system. Using a familiar storage interface allows the QLE406xC to support proven LUN and target-level fail-over functionality, storage SAN boot, and existing SAN management and application software.
Comprehensive Operating System (OS) Support
QLogic offers the broadest range of support for all major operating systems to ensure OS and hardware server compatibility. Drivers are fully tested with industry-recognized certifications from all the major operating systems, including Windows, Linux®, and Solaris™.
Storage partner certifications, combined with agency and regulatory testing, ensures that all products meet world compliance hardware and software specifications. All HBAs are tested extensively with third-party hardware, along with multiple software applications, to ensure best-in-class SAN interoperability and compatibility. You can be confident purchasing QLogic HBAs to meet your storage networking needs.
