This week’s article should have been part 2 of our look into iSCSI but I wanted to take a break while the SC09 conference is happening. So the next parts of the iSCSI article will come later. This week I want to discuss a new but potentially very important trend in storage Р“Cloud Storage.”
This type of storage has a number of names. For example it is sometimes called ‚Äúon-line archiving‚Äù or ‚ÄúRAIN – Redundant Arrray of Inexpensive Nodes‚Äù, but ‚ÄúCloud Storage,‚Äù for better or for worse, is the name that is the most popular. The overall concept is fairly simple – Cloud Storage takes distributed storage nodes and combines them using a file system of some type, to create a single storage system but with fairly low performance (hence the phrase ‚Äúon-line archive‚Äù). It relies on replication rather than RAID for data resiliency by having multiple copies of the data on various nodes…
