Software RAID: Functionality on Dell Value Line Servers
Dell made use of a range of Redundant Array of Independent Disks (RAID) sub systems for the purpose of data redundancy. The aim was to recover data and prevent loss of information through this technique. This paper examines how Dell successfully incorporated this on their computers and met their system requirements. The success of RAID software was followed by the implementation of these disks into the Dell PowerEdge T110, R210, T310, and R510 servers. The paper details the advantages, architecture and implementation of this software into Dell servers. The two ways in which this is implemented is specified in the paper. It talks about software RAID, its varied features, and the different levels of RAID that are supported through it. The server-based RAID subsystem comes in two separate categories that are dependent on the processor used with RAID engines. System administrators can know which RAID software to implement once they understand the differences between Software RAID and Hardware RAID. Hardware RAID, just like its name, operates as separate disks outside the operating system. Software RAID, on the other hand, is conducted on the host system and they require only a simple interface because they rely on the host system for memory and processing capabilities. The functions of the software RAID depends however on the OS. To know more about how it works with Dell, read the deeply explained illustration in the paper.
