Abstract
Serial Attached SCSI (SAS) has been the storage technology of choice for business-critical applications in data centers for nearly 15 years, starting with 3Gb/s SAS in 2004, then doubling in effective bandwidth with each new generation. The next generation in development is 24G SAS, with end-user products anticipated in late 2020. Optimized for both solid state drives (SSDs) and hard disk drives (HDDs), 24G SAS is backward compatible with existing tried-and-true SAS ecosystems. The end result is unmatched by other storage technologies: a highly scalable and flexible technology, offering the fastest per lane performance with the most reliable device management of any drive technology available. 24G SAS will be the technology of choice for all-flash deployments, as well as tiered or cached systems supporting both HDD and SSD devices.
