MegaRA ID Enterpr ise 1600 Har dware Guide 6 RA ID Levels RAID (R edundant A rray of Independent Disk s) is a collection of specifications th at describe a system for ensuring the reliability and stability of data stored on large disk subsy stems. A RAID sy stem can be implem ented in a num ber of differen t version s (or RAID L evels). The standar[...]

Chapter 2 I ntroduction to RAI D 7 Disk Striping Disk striping w r ites data across multiple disk drives instead of just one disk drive. Disk striping involves partitioning each drive storage space into stripes that can vary in size from 2 KB to 128 KB. These stripes are interleaved in a repeated sequential man ner. The combined s torage space is c[...]

MegaRA ID Enterpr ise 1600 Har dware Guide 8 Disk Mirroring With mirroring (used in RAID 1), data written to one disk drive is sim ultaneously w ritten to another disk drive.
