[. . . ] 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. -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. Based on the previous figure, the entry should be PCI Bus #0 PCI Dev#12 Port:D000 Irq:11. The enabling of the toolbar buttons signifies a successful connection. following submenu appears on the screen: The 3. 2 Connecting and Disconnecting from a Disk Array 3-5 ASUS GUI RAID Manager: Basic Operations at Startup 2. From the COM Port# drop-down list box, select which COM port on the local host is connected to the controller via the RS-232 cable. To select a different COM port, click on the down-arrow button at the right of the box, then select the desired option. From the Baud Rate drop-down list box, select the baud rate setting on the RS-232 port of the controller. You can modify the baud rate on the controller through the on-board console interface or through the GUI RAID Manager. For information on the latter, see Chapter 4, Array 3-6 3. 2 Connecting and Disconnecting from a Disk Array ASUS GUI RAID Manager: Basic Operations at Startup Management. For information about the console interface, see the documentation that came with the controller. The enabling of the toolbar buttons signifies a successful connection. 4Connecting to a PCI-to-SCSI controller from a remote station (via network) 1. The Settings of SNMP Interface dialog box appears on the screen: 3. 2 Connecting and Disconnecting from a Disk Array 3-7 ASUS GUI RAID Manager: Basic Operations at Startup 3. In the Agent Name or IP Address text box, type in the IP address of the local host where the target disk array system is connected. In the Community Name text box, type in one of the community names of the SNMP agent. Community names act as passwords that screen accesses to the SNMP agent of a particular network device. Before access is granted to a requesting station, this station must incorporate a valid community name to its request; otherwise, the SNMP agent will deny access to the system. By default, most network devices use "public" as one of their community names. In the Agent-side Communication Type section, click on the Host Bus Interface option button. [. . . ] In disk mirroring, the total disk capacity is equivalent to half the sum of the capacities of all SCSI drives in the combination. Thus, combining four 1GB SCSI drives, for example, would create a single logical drive with a total disk capacity of 2GB. This combination of drives appears to the system as a single logical drive. RAID 1 is simple and easy to implement; however, it is more expensive as it doubles investment required for a non-redundant disk array implementation.
