Storage is a vital part of an enterprise IT infrastructure and IP telephony solution. RAID (Redundant Array of Independent Disks) is the standard for combining multiple independent hard drives to form one large logical array. Various RAID levels define the way data is distributed and redundant capacity is implemented. Each RAID level represents very different trade-offs in terms of cost, availability, and performance. RAID 5 has long been considered the standard in data-redundancy policies for application servers. As performance demands from I/O hungry applications such as call recording, transaction logging, and other write intensive applications increase, the RAID 5 arrays are becoming overworked and reaching I/O throughput limitations.
