Summary: Decoding UCS Invicta – Part 3

In part one of this series we covered the internals of HDDs, in part two we went over the internals of SSD, In part three we continue reviewing storage concepts to refresh or learn the right lingo.

Lets start by understanding “Redundant Array of Independent Disks” (RAID). There are RAID levels like RAID0 and RAID1 that are easily to understand and others like RAID5 and RAID6, which many sysadmins misunderstand.
