Arthur Cole spoke with Harry Mason, director of industry marketing, Storage Components Group, LSI.
Cole: The adoption cycle for 6G SAS is just getting under way. How can the technology be put to the best use as enterprises transition to virtual and cloud storage environments?
Mason: One of the great benefits of SAS technology is that it supports a building block approach via common components and common infrastructure. Advances in performance, security and scalability in a cost-effective manner will enable new applications in the enterprise. In the database environment, 6Gbps SAS will provide quicker access to data and high levels of data protection. In the long-tail nearline storage environment, SAS enables incorporation of SATA drives and thus high-capacity, lower-cost solutions.
Cole: How will chip-level integration of 6G SAS solutions, like LSI's RAID-on-Chip and MegaRAID lines, affect the enterprise's ability to roll out the technology?
Mason: LSI provides 6Gbps SAS solutions at the adapter level and at the ROMB (RAID on Motherboard) level. This is a familiar deployment model. For the last few product generations, this is the way our customers have implemented RAID solutions on servers. LSI continues to drive richer functionality into the solutions on both the SAS side, with advent of 6 Gbps SAS, and on the MegaRAID side, with new features and functions. In this way we will continue to waterfall enterprise features into more segments of the server market.
Cole: Do you think 6G SAS will spur greater demand for direct-attached storage solutions?
Mason: 6Gbps SAS in conjunction with intelligent applications will increase the overall value proposition for SAS in DAS solutions. This will help SAS penetrate at higher levels in external storage. New features such as self-configuring expanders enable creation of richer DAS topologies.
