#Globalsan activation key software#
You may call it niche, since it's mostly used in large scale network storage system, and seldom used by home / small office users, but it's not some legacy technology.Īn iSCSI target (or the "network hard-drive" if you prefer) is not necessary to be a "SCSI" device - the iSCSI is merely a pure-virtual software level, so that the initiator host (the Computer) can tell the target (the hard-drive) where to fetch data.
ISCSI is a virtual SCSI channel over TCP/IP network. Try it, I think you can try GlobalSan initiator for 14 days for free.
So, you can create a volume on your NAS, as I do, where I store all my 18,000 mp3's for iTunes and 123Gb of photo's for my Aperture and 100Gb of video for my iMovie and it all runs as fast as if it was on a local, internal drive. You couldn't do that by mapping a drive on your NAS. Even on very low cost NASes, you can see data transfer rates of perhaps 85MegaBytes per second, yes, I did say per second. To stream video from a NAS to your iMac by just mapping a drive to it can be very frustrating because you can't normally reach the data transfer rates required but with iSCSI you can achieve very fast data transfer rates. Conversely iSCSI uses the same fast data transfer technology of SCSI but over the internet or more likely over your local LAN.
SCSI is very efficient but uses an interface cable. Many decent NAS units, mine's a Synology one, allow iSCSI to send and receive data to and from the NAS. Many FibreChannel technologies are currently being replaced by iSCSI because not only is iSCSI fast, it runs over cheap cat5 cable so it is still very much cutting edge technology.
