How do SSDs improve existing storage solutions?
Many types of application software (transaction processing, batch processing, query or decision support analysis) can benefit from the super-fast access times SSDs offer. Adding a small amount of SSDs to an environment can result in a significant performance improvement and eliminate a major performance bottleneck for an application, while dropping power requirements significantly. When deployed in a storage system, SSD drive shelves can deliver performance gains of more than 16X that of SATA drive shelves and 5X of FC shelves. On the power savings front, if a single brick of SSD is deployed instead of four bricks of 15K FC drives, users can save up to 1045 Watts per hour. The four FC bricks, under load, use 1232 Watts per hour and the single SSD brick uses only 186.6 Watts per hour, resulting in a difference of 1045.4 Watts. The performance and power savings advantages are undeniable. Q) Is it possible for storage vendors to guarantee the performance of an SSD? A) For some vendors, ab
