An iSCSI target operates just like an ordinary USB or 1394 external disk: you can format the volume with Disk Utility, paste icons, create directory, copy files, delete files, and grab deleted files back from the system trash can.

When you mount an iSCSI target on to your Mac OS X desktop, it's different from an SMB/AFP shared volume. For example, a medium level NAS from QNAP or Synology may use 4 SATA3 hard-drives, configure to RAID 5, format main partition to EXT-4, create a virtual logic partition that takes 20% of total usable spaces, and assign it as iSCSI target. ISO image file used by VMWare or Parallel. You can imagine it like an virtual hard-drive. The storage device will translate SCSI command to HFS/EXT-3/EXT-4 file system access command, so that it may access the real physical storage.

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. If prompted, save your changes and reboot your Mac. From the menu click on File, then Quit LaunchControl. Now click on the ‘‘ button located at the bottom right of the pane to remove it from the list. Many decent NAS units, mine's a Synology one, allow iSCSI to send and receive data to and from the NAS. After the application is done parsing, find the item in the left pane and click on it once to highlight it. It will be key for management to continue to develop the processes and procedures that support, rather than hinder that growth. 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.
