For information on how to connect, see the Connecting and Disconnecting from a Disk Array System section of this chapter. 4Starting the GUI RAID Manager for remote management via telephone line 1. Ensure that a modem is connected to the RS-232 port of your SCSI-to-SCSI controller, and to the serial interface of your GUI RAID Manager station. Check that the baud rates of the ports and the modems are set accordingly. From the GUI RAID Manager station, dial in the number of the modem connected to the controller. 3-3 3. 1 Starting the GUI RAID Manager ASUS GUI RAID Manager: Basic Operations at Startup 3. When a link is established, connect to the disk array system. For information on how to connect, see the Connecting and Disconnecting from a Disk Array System section of this chapter. 3. 2 Connecting and Disconnecting from a Disk Array The GUI RAID Manager provides a feature that facilitates connection and disconnection from disk array systems. Before management can be performed on a particular disk array system, you need to establish first a connection between your GUI RAID Manager station and the target system. Once a connection is established successfully, management can be started. Disconnection is used for breaking the link between the GUI RAID Manager station and the array system. This option is particularly useful in cases where multiple disk array systems are being managed at the same time - instead of restarting the GUI RAID Manager every time you need to switch to another system, you just need to disconnect from the current system and then connect to a new one. The following discusses the various ways of connecting to a disk array system. Information on disconnection is provided at the latter part of this section. 4 Connecting to a PCI-to-SCSI controller from the local host 1. -or- 3-4 3. 2 Connecting and Disconnecting from a Disk Array ASUS GUI RAID Manager: Basic Operations at Startup Click on the Connect/Open command button. following submenu appears on the screen: The Note that there will be one PCI Bus entry for each PCI-toSCSI controller installed. [. . . ] In cases where multiple concurrent I/Os are occurring, these I/Os can be distributed between two disk copies thus reducing total effective data access time. RAID 1(0+1) RAID 1(0+1) combines RAID 0 and RAID 1 -- Mirroring and Disk Striping. RAID (0+1) allows multiple drive failure because of the full redundancy of the hard disk drives. If more than two hard disk drives are chosen for RAID 1, RAID (0+1) will be performed automatically. F IMPORTANT: RAID (0+1) will not appear in the list of RAID levels supported by the controller. If you wish to perform RAID 1, the controller will determine whether to perform RAID 1 or RAID (0+1). [. . . ]
