whitepaper Whitepaper:  EqualLogic TCO Analysis by ESG Lab2009-11-04 Dell EqualLogic
  This ESG Lab report examines the economic excellence of highly scalable EqualLogic iSCSI storage solutions compared to traditional direct attached storage (DAS), Fibre Channel storage area network (FC SAN), and multi-protocol solutions (defined as systems that provide FC, iSCSI, and NAS connectivity). After testing EqualLogic storage in the lab using an infrastructure encompassing seven generations of EqualLogic hardware, ESG Lab calculated the total cost of ownership (TCO) over five years for an organization requiring 80 raw terabytes of storage capacity using systems available for purchase today.

whitepaper Growth Solutions for Data Storage: Meeting the Needs Now and in the Future for Small Business2009-05-01 Synology
  Businesses of all sizes should look to implementing storage solutions that offer growth and expansion capabilities as their organization grow. Growing offices, can plan for the future by using any of the four expansion methods; growing by expanding disk capacity, increasing the amount of disks within the RAID volume, or growing in hardware performance. In this paper ideal small business solutions will encompass all four growth expansion methods as they will be the most cost-effective over time and allow for the greatest of options. Synology Disk Stations meet the needs of growing business through any of the four expansion methods.

whitepaper Comprehending the Tradeoffs Between Deploying Oracle Database on RAID 5 and RAID 10 Storage Configurations2009-04-01 Dell
  Redundant Array of Independent Disks (RAID) technology is used to improve performance and availability of the underlying storage arrays for any application. With RAID implementations, performance is improved by distributing I/O across many physical disks and availability is increased with the data rebuilding capability. But both high availability and high performance comes at a price, which are different for different RAID implementations. Most of the time database and storage administrators ask the age-old question - whether to go with RAID 10 or RAID 5 for their database deployment. Customers struggle to make right tradeoffs between these two RAID implementations for their database deployments. This white paper evaluates different tradeoffs including performance, cost, and availability while evaluating RAID 10 compared to RAID 5.

whitepaper Data Recovery and RAID Drives2009-03-27 CPR Tools
  This paper addresses the recovery of information (user files) from hard drives which have been used in RAID systems. There is a history of successful data recovery efforts when working with drives from RAID systems. RAID systems are unique in that multiple drives can be used to store the data and as the 'R' in the acronym states they are 'Redundant'. This redundancy not only helps the system administrator or IT staff keep the systems running when a drive fails but also aids the data recovery engineer in recovery efforts when multiple drives fail. Simple mirror RAID (RAID 1) recoveries are far less complex than any other as the file structure(s) are intact on a complete physical volume.

whitepaper The Mathematics of RAID-62008-07-02 Zytor
  RAID-6 supports losing any two drives. The way this is done is by computing two syndromes, generally referred P and Q. The algebra used for this is the algebra of a Galois Field, GF(28). A smaller or larger field could also be used, however, a smaller field would limit the number of drives possible, and a larger field would require extremely large tables. GF(28) allows for a maximum of 257 drives, 255 (28 - 1) of which can be data drives; the reason for this is shown in the paper.

whitepaper Undetected Disk Errors in RAID Arrays2008-07-01 IBM
  Though remarkably reliable, disk drives do fail occasionally. Most failures can be detected immediately; moreover, such failures can be modeled and addressed using technologies such as RAID (Redundant Arrays of Independent Disks). Unfortunately, disk drives can experience errors that are undetected by the drive - which the paper refers to as Undetected Disk Errors (UDEs). These errors can cause silent data corruption that may go completely undetected (until a system or application malfunction) or may be detected by software in the storage I/O stack. Continual increases in disk densities or in storage array sizes and more significantly the introduction of desktop-class drives in enterprise storage systems are increasing the likelihood of UDEs in a given system.
