Microsemi Corporation releases a new generation of storage input/output (I/O) controller products, the SmartROC 3100 and SmartIOC 2100, powered by the company's Unified Smart Storage Stack. With the release of this new Smart Storage Platform, Microsemi significantly enhances its server storage solution offerings for data center applications.

With over 30 million unit shipments worldwide to date, Microsemi's Smart Storage Stack offers one of the industry's most reliable and highest performing storage controller software platforms. The Smart Storage Platform now available in production release delivers advanced security features, such as maxCrypto controller-based encryption and enterprise-class data protection support, while providing high performance and a significant advantage in operating costs due to significant power savings compared to previous generations and competing product offerings. The solution achieves up to 1.6 million random read I/O operations per second and delivers greater than 35 percent power savings compared to competing solutions.

Microsemi's smart storage solutions can be used in any server storage application with 12 Gbps SAS or 6 Gbps SATA hard disk drives (HDDs) or solid state drives (SSDs). SAS/SATA HDDs and SSDs are forecasted by market research firm IDC to represent 80 percent of all enterprise drives shipped on an annual basis through the end of the decade. Microsemi's smart storage solutions are performance-optimized around SSD performance and power-optimized for HDD-based cold storage. Features are available for both deployment extremes in addition to a myriad of hybrid SSD/HDD applications. They also support data protection schemes including RAID, erasure coding and data replication.
