Enterprise flash drives are designed to dramatically increase the performance of latency sensitive applications. Enterprise flash drives, also known as solid state drives (SSD), contain no moving parts and appear as standard drives to existing storage management tools, allowing administrators to manage Tier 0 without special processes or custom tools or extra training. Tier 0 EFDs are ideally suited for applications with high transaction rates and those requiring the fastest possible retrieval and storage of data, such as currency exchange and electronic trading systems, or real-time data acquisition and processing. They also can prove to be extremely good for highly read-intensive workloads like search engine databases.
The EFDs are designed to deliver millisecond application response times and up to 30 times more I/O operations per second (IOPS) than traditional Fibre Channel hard disk drives. Additionally, EFDs consume significantly less energy per IOPS than traditional hard disk drives, providing the opportunity for significantly increased TCO by reducing the data center energy and space footprints. Database performance has long been constrained by the I/O capability of hard disk drives (HDD), and the performance of the HDD has been limited by intrinsic mechanical delays of head seek and rotational latency. EFDs, however, have no moving parts and therefore no seek or rotational latency delays, which dramatically improves their ability to sustain very high number of IOPS with very low overall response times.
Over the past 25 years, the rotational speeds of HDDs have improved from 3,600 rpm to 15,000 rpm, yielding only four times the improvement in IOPS when the rest of the computer technologies like CPU speeds saw double digit growth. EFD technology represents a significant leap in performance and may sustain up to 30 times the IOPS of traditional HDD technology. Proper use of EFDs can deliver vastly increased performance to the database application when compared to traditional Fibre Channel drives, both in transaction rates per minute as well as transaction response time.
