iSCSI - what is it good for and how to use?
Ok, this is probably the wrong place to ask, and I am sure everyone reading this will yawn and think "This guy is a real Dumbo!" So can you please point me to some URL describing how, why I would u...
Some key things to remember about iscsi is;
- an iscsi volume is attached to a single PC like an external drive (ie its a virtual drive stored on the nas).
- an iscsi volume is *not* normally shared between multiple PC's, this will pretty much corrupt the volume when 1 computer overwrites data from another pc (that said, iscsi volumes can be shared between 'clustered' servers that are designed to avoid simultanious access problems)
- iscsi is useful for things that will not normally work on a network connection (like database files, some versions of windows backup, various accounting softwares, etc).
- data on iscsi volumes can be shared *by the PC*, but the iscsi volume itself can not be shared (see above)
- if you have ever worked with virtual pc or vm ware or other virtualization, iscsi is like a virtual hard disk file, but is stored on the nas and goes through the iscsi protocol instead of being accessed directly on a hard drive.
