    • WHITE PaPEr 8 Reasons to Choose QLogic TrueScale™ InfiniBand™ Adapters TrueScale Architecture Enables Superior Scalable Performance When messaging requirements dominate in an application, QLogic’s Introduction advantage over alternative interconnect solutions is significant at Interconnect performance has become a key factor in overall small scales and dramatic at large scale. The fundamental reason is application and clustered system performance. This will continue that QLogic’s architecture and interfaces are optimized to spend the to be the case as applications become more complex, more least amount of time on parallel communications, so that applications sophisticated, and are scaled onto increasingly larger clusters to can make better use of their computation resources and generate accelerate the time-to-solution for critical business and scientific answers quicker. problems. QLogic’s IB adapters deliver superior rOI by lowering both capital and operating expense. QLogic adapter’s superior ability to scale Superior Performance real-world applications means that organizations can achieve Reason #1: Highest Message Rate Performance better utilization of their clustered computing assets, and therefore Designed to leverage the capabilities of multi-core servers, the maximize their rOI. In addition, QLogic’s solutions allow bridging TrueScale architecture can handle the increase in communication to both Ethernet and FC data center fabrics, giving customers the requirements in a multi-core environment. With the prevalence flexibility to implement a converged fabric for their data center needs of multi-core compute nodes in today’s HPC clusters, the while leveraging investments in their existing infrastructure. communications burden per adapter is far greater than when single and dual-core servers were the norm. Reason #3: Highest Overall Bandwidth on PCI Express Gen1 Platforms To maintain a balanced system and make effective use of the QLogic is the only supplier of PCI Express Gen1 x16 IB adapters on the available cores, the interconnect must be able to efficiently process market. For customers deploying PCI Express Gen1 platforms, only a large number of messages at varied patterns. Unmatched in QLogic TrueScale adapters can take full advantage of the bandwidth message rate performance, the TrueScale architecture is the ideal capability of the Double Date rate (DDr) InfiniBand aSIC and achieve choice for multi-core compute nodes. true DDr performance. Reason #2: Lowest Scalable Latency The following table lists the message rate, scalable latency, and HPC application codes have become more parallelized to take peak bandwidth performance of the two TrueScale DDr adapters, advantage of advances in cluster computing. as a result, these which offers the fastest time to solution and the highest rOI for HPC codes are being deployed on larger systems now that they can take applications. advantage of the additional compute resources available. Due to the connectionless design and light-weight memory footprint per process, only the TrueScale adapter was designed from the ground up to scale efficiently with the size of the fabric.
