Hi SLUG, not so much a linux question, but having difficulty finding clear answer.
When it comes to speaking of JBOD v's RAID 0 (specifically), there are plenty of opinions, but haven't found a clear definition yet. I'm not worried about RAID's 1 & up. I understand the following terms to have the following definitions underlying them. But is this understanding correct? Striping: Effectively a RAID 0 array, wherein there is no guarantee which piece of what file is written to which disk in the array. Spanning: 2 (or more) disks presented as single logical volume ( / Drive), however file A might be written to Disk 1 and file B might be written to Disk 2. Concatenation: 2 (or more) disks presented as single logical volume ( / Drive), however Disk 1 is filled before Disk 2 is filled before Disk 3, etc. So, the questions are; 1. Are these understandings correct? 2. If not, what am I missing? 3. Which implementation is JBOD? Spanning or Concatenation?
