For seamless integration and flexibility of drive use, LSI leverages LSISS2520 AAMUX and SAS-to-SATA bridging technology in the LSISS9252 interposer card which integrates a SAS-SATA drive bridge enabling customers to build economical enterprise storage systems. These systems can accommodate low-cost, high capacity Serial ATA (SATA) hard drives without sacrificing reliability, manageability, or data availability. LSI SAS bridge technology enhances SATA drives with essential enterprise-class features on par with Serial Attached SCSI (SAS) or Fibre Channel disk drives. LSI AAMUX technology enables single-ported SATA drives to connect like native dual-ported drives for use in enterprise storage systems using SAS expanders. The LSISS2520 device is based on 5th generation technology bringing true active-active multiplexing to the SATA drive, with both ports simultaneously available, much like dual-ported FC and SAS drives. A dual-ported activeactive SATA drive solution results in much higher performance and reduced system development costs when compared to previous system implementations. Because software failover is no longer required, this approach greatly simplifies system software complexity and manageability.
