MSA 2040 Performance

With the addition of performance tiering, stored data is analyzed every five seconds for activity. Active, or "hot," data is moved from a lower tier to an upper one, where it can be accessed more quickly. The hottest data is moved to SSDs, if present, which deliver the fastest random access times. Data that's been idle for more than a day is demoted to a lower tier. Alternatively, one or more SSDs can be manually assigned as read cache volumes, able to improve array performance, for example, during tax season or at a company's year-end close. The setting is transparent to the user; all they see is faster data access. According to a company spokesperson, the addition of a single SSD can improve random access performance by two to three times. To help with scalability and further boost performance, the new firmware also implements wide striping. This permits data to be spread across a larger number of spindles than otherwise possible so that when more spindles are added, the load can be rebalanced across them all with no manual intervention. Starting list price for the MSA 2040 is $3,999.
