Marvell QLogic 2690 系列光纤通道适配器

单端口、双端口和四端口增强版 Gen 5 FC (16GFC) 光纤通道适配器借助低 CPU 使用率和全硬件卸载能力为行业提供领先的原生 FC 性能

QLogic 2690 系列光纤通道适配器

The Marvell® QLogic® 2690 Series of Enhanced Gen 5 (16Gb) Fibre Channel (FC) adapters comprise a complete portfolio of single, dual, and quad-port adapters, designed for enterprise data centers requiring the ultimate in FC performance, power efficiency, reliability, and investment protection for demanding virtualized and private cloud environments. These adapters deliver the industry’s leading FC performance with up to 2.6 million IOPS (up to 650K IOPS per port) with optimal load balancing and linear performance scalability per port. The QLogic port-isolation design provides independent data paths for each port, prevents errors and firmware crashes from propagating across all ports. It also extends predictable and scalable performance across all ports. The 2690 Series adapters support QLogic StorFusion™ technology offering comprehensive port diagnostics, rapid provisioning, and guaranteed performance service level agreements (SLAs) when used in conjunction with Brocade® Gen 5 FC Fabric. QLogic 2690 Series adapters provide unmatched operational efficiency with up to 75% lower power per port compared to the competition for reduced total cost of ownership (TCO). They also leverage QLogic StarPower™ technology with dynamic and adaptive power management features to optimize power and thermal footprints in the data center.
