Appendix B: RAID Basics Overview A Redundant Array of Independent Disks (RAID) is an array of several hard disks that provide data security and high performance. A RAID system accesses several hard disks simultaneously, which improves I/O performance over a single hard disk. Data security is enhanced by a RAID, since data loss due to a hard disk failure is minimized by regenerating redundant data from the other RAID hard disks.
This is excellent for complete data security. RAID 5 RAID 5 offers data security and it is best suited for networks that perform many small I/O transactions at the same time, as well as applications that require data security such as office automation and online customer service. Use it also for applications with high read requests but low write requests. RAID 5 includes disk striping at the byte level and parity information is written to several hard disk drives.
Disk Usage When all disks are of the same size, and used in RAID, Thecus IP storage disk usage percentage is listed below: RAID Level Percentage Used RAID 0 100% RAID 1 1/n x 100% RAID 5 (n-1)/n x 100% RAID 6 (n-2)/n x 100% RAID 10 50% JBOD 100% n：HDD number 146
Appendix C: Active Directory Basics Overview With Windows 2000, Microsoft introduced Active Directory (ADS), which is a large database/information store. Prior to Active Directory the Windows OS could not store additional information in its domain database. Active Directory also solved the problem of locating resources; which previously relied on Network Neighborhood, and was slow. Managing users and groups were among other issues Active Directory solved.
