As online transaction processing (OLTP) and other key enterprise applications take on increasing workloads, administrators are pressed to find ways of handling the performance demands on their storage systems. Traditional mechanical hard disk drives (HDDs) have built-in performance characteristics such as seek time and rotational latency that can make it difficult to keep up with escalating needs from transaction-intensive applications.A new option now available for Dell? EqualLogic? PS Series storage is solid-state drive (SSD) technology. SSDs offer exceptional performance?enabling significantly faster random read/write response time compared with traditional mechanical HDDs?along with enhanced reliability, energy efficiency, and space efficiency. To help organizations take advantage of SSD technology, the Dell EqualLogic PS6000S storage array provides outstanding performance in a cost-effective SSD-based array that can easily integrate into multitiered EqualLogic Internet SCSI (iSCSI) storage area networks (SANs).Although SSDs can offer dramatic performance advantages, their cost and capacity limitations make them most effective when deployed as a targeted solution in particular use cases. For example, SSDs can be a key solution for workloads that require low latency and high IOPS combined with limited capacity (such as virtual desktop infrastructure deployments), and those in which the transfer block size is small (such as OLTP applications). In a tiered storage environment, SSDs enable IT organizations to provide a customized balance of cost-effective capacity and performance with exceptional throughput and response time.SSDs have emerged as an excellent high-performance storage option for certain enterprise workloads. As part of the Dell EqualLogic PS Series of virtualized storage arrays, the EqualLogic PS6000S SSD array can help organizations simply, scalably, and cost-effectively meet escalating application performance demands with enhanced reliability and energy efficiency.
