With a diverse portfolio of MegaRAID adapters, including Entry, Value, and Feature boards ranging from four to sixteen ports, LSI offers a solution for any storage requirement. The combination of LSI MegaRAID SAS/SATA and Seagate ES.2 SAS drives offers a unique benefit to system builders and channel OEMs. With the MegaRAID 3.5 release, the MegaRAID SAS 8700 and 8800 series products now support single-controller Multipathing (failover) and Load Balancing. Together, these two new features take full advantage of the dual port, full duplex, and concurrent active channels on the ES.2 SAS hard drives. Multipathing takes advantage of dual port drives by detecting and using multiple paths of communication. This increases reliability and fault tolerance in the case where the cabling becomes faulty or disconnected, or where one port on a drive becomes inactive. In this instance, Multipathing allows the MegaRAID adapter to access the hard drive via an alternate path, thereby maintaining communication and eliminating downtime. Load balancing, working in tandem with Multipathing, is a powerful feature for improving application performance. While Multipathing allows for use of multiple paths, it is Load Balancing that intelligently distributes read/write requests to the multiple paths. This maximizes throughput between the MegaRAID adapter and the hard drive, removes bottlenecks and improves overall system performance. In fact, LSI has seen Load Balancing improve large block sequential reads by up to 40% and modestly improve random writes as well. MegaRAID SAS/SATA adapters used with Seagate ES.2 SAS hard drives provides the most ideal storage solution for Low-Cost Server and Nearline applications. Not only are system builders and other channel customers able to purchase these SAS building blocks at SATA pricing, but they can also take full advantage of the SAS performance and reliability features. No other vendors can match this capability today.
