The QLogic QMH2462 4Gb FC HBA Adapter provides the c-Class BladeSystem with two 4Gb Fibre Channel ports for fast and reliable SAN connectivity. Through the implementation of a SAN with the HP BladeSystem, customers can achieve improved data availability, easily scale capacity, and realize management cost savings from consolidating disk resources. Fibre Channel capability is achieved using a QLogic FC Mezzanine HBA specifically designed for HP c-Class BladeSystem. The HP BladeSystem is optimized for HP Storage and compatible with third party storage vendors. This adapter is RoHS compliant, has low power requirements, 150,000 IOPS per port 4Gb performance and driver support for Windows and Linux. The Linux driver includes a new and improved failover feature that now includes dynamic load balancing. QLogic embraces the use of common drivers which means that customers can standardize on one QLogic driver whether they are using the QMH2462 or other 4Gb and 2Gb HBAs powered by QLogic. Benefit, features and specifications include:
•4Gb bandwidth with industry leading 150,000 IOPS per port performance.
•Intelligent Interleaved Direct Memory Access (iiDMA) ensures maximum utilization of the link bandwidth.
•Out of Order Frame Reassembly (OoOFR) improves performance by eliminating the need to retransmit the entire I/O block.
•Customers can standardize on common drivers for 4Gb and 2Gb adapters used across multiple server platforms.
•4/2/1 Gb bandwidth auto-negotiation
•Low power requirements and heat dissipation.
•Linux driver failover feature for all Linux kernels and now with dynamic load balancing.
•No server-reboot requirements for driver and firmware upgrades.
•T10 cyclic redundancy check (CRC) ensures end-to-end data integrity across SANs.
•Overlapping Protection Domains (OPD) ensures that data is not left unprotected even for the smallest fraction of time.
