The ServeRAID M5115 SAS/SATA Controller is a high-performance offering for IBM Flex System™ compute nodes. It enables a high-performance RAID solution composed of combinations of SAS or SATA drives or high-throughput solid-state drives (SSDs). The offering is designed around a base RAID adapter with a set of upgrades that are rich with features, designed to minimize parts-on-the-floor, optimized for storage performance, and consistent with existing industry-leading ServeRAID products. The ServeRAID M5115 SAS/SATA Controller for IBM Flex System is capable of delivering several focused solutions depending on business needs, offering two-drive HDD connectivity or support for up to eight 1.8-inch SSDs or combinations of HDDs and SSDs. Software upgrades include SSD performance features or an extra layer of redundancy with RAID 6. These solutions are realized by pairing M5115 with one or more available hardware kits and Feature-on-Demand license upgrades.
