Software Specifi cations An Example of an iSCSI DV SAN • The ATTO Xtend SAN package for Mac OS X Xtend SAN is installed on the , PowerBooks and Power Macs consists of an iSCSI device driver and a management interface: Xtend SAN allows Macintosh hosts to initiate I/O to an iSCSI target, such as an ATTO iPBridge or iSCSI-ready storage. In the example shown, ATTO iPBridges are used to provide –The iSCSI Device Driver is responsible for iSCSI functionality to SCSI storage devices, such as autoloaders and disk arrays. The iPBridge moving data from the storage stack over 2700 is shown providing iSCSI connectivity to an RAID array. Macintosh users running to the network stack, where it can be Xtend SAN on their workstations are now able to communicate with iSCSI storage. passed to and from the outside world using a standard Gigabit Ethernet network. –The management interface is designed to allow users the ability to confi gure specifi c protocol options and manage target devices through a graphical user interface.
