These include the following topics: System description Feature summary Feature highlights 1-1 ASUS GUI RAID Manager: Introduction 1. 1 System Description The ASUS' GUI RAID Manager is a Windows-based program specifically designed for use in managing disk array systems implemented using any of ASUS' line of PCI-to-SCSI or SCSIto-SCSI controllers (GUI stands for graphic user interface. ) The GUI RAID Manager provides a user-friendly interface that facilitates understanding of the relationship between disk array elements and simplifies the normally complicated process of array configuration. The GUI RAID Manager also provides realtime reporting on the status of the entire array, thus making the task of monitoring disk arrays virtually effortless. The GUI RAID Manager complements the on-board console interface found on the ASUS' SCSI-to-SCSI controllers and a line of host-based, text-based RAID Managers providing the same functionality, but with greater ease of use. The following sections describe the outstanding features of the GUI RAID Manager. 1-2 1. 1 System Description ASUS GUI RAID Manager: Introduction 1. 2 Feature Summary The list below summarizes the GUI RAID Manager features. User-friendly graphical interface running under the Windows NT or Windows 95/98 environment Supports the entire new line of ASUS' SCSI-to-SCSI and PCI-to-SCSI RAID controllers Communicates with the controllers via the RS-232 cable, over a LAN, telephone line, Internet, over the PCI bus (PCI-to-SCSI controllers only), or over the SCSI bus (SCSI-to-SCSI controllers only) Supports multiple instances of RAID managers over the network, allowing multiple management sessions with a disk array system Illustrates graphically and clearly the relationship between various disk array elements At a glance monitoring of the entire disk array status Supports remote management over the network of host/agent running Windows NT or Windows 95/98 via the Simple Network Management Protocol (SNMP) Supports remote management over the telephone line via a pair of modems; one directly connected to the RS-232 interface of the controller, the other connected to the serial port of the remote station running the GUI RAID Manager Provides standard disk array functions, including examining and modifying controller configuration; viewing and monitoring configuration and status of physical drives; scanning in new physical drives; creating, deleting, and monitoring configuration and status of 1. 2 Feature Summary 1-3 ASUS GUI RAID Manager: Introduction logical drives; rebuilding logical drives; defining spare drives; creating, deleting, and partitioning logical volumes; and mapping logical volume partitions to specific host channels/LUNs Enclosure management functions, including defining multiple customizable enclosures, dimensions, and number of drives; monitoring physical drives, power supply, fan, and temperature status; displaying relative location of failed physical drives for reduced risk of replacing the wrong drives Provides a log file for logging in various event occurrences, including the time when an event occurs, event severity, and event description; log file can be accessed using any text editor program Supports statistics throughput history monitoring for displaying I/O Provides innovative, user-configurable event notification functions Ø Configurable severity level qualifying the event severity that will initiate the selected notification sequence Ø Configurable latency time between event occurrence and notification sequence initiation provides local administrator the option to abort issuance of the notification sequence Ø Pager/telephone notification via a local modem: · Provides user-configurable address book for keeping names and numbers to be paged/called, and message to be sent 1-4 1. 2 Feature Summary ASUS GUI RAID Manager: Introduction · Optional notification retransmission until addressee responds locally at the console or remotely over the Local Area Network (LAN), Internet, or modem Configurable latency time between notification retransmission; can be set to different values at different times of the day · Ø E-Mail notification via the MAPI service of Windows NT or Windows 95/98: · Provides user-configurable address book for keeping names, E-mail addresses, and messages to be sent Ø Broadcast notification over the LAN: · Provides user-configurable address book containing names/groups and network addresses to which the specified message will be broadcasted Broadcasts user-configurable message along with the event description · Ø Facsimile (FAX) notification via a local FAX/modem: · Provides user-configurable address book containing names, FAX numbers, and messages to be sent User-configurable FAX messages sent along with the event description Automatic message retransmission in the event previous transmission attempts fail · · 1. 2 Feature Summary 1-5 ASUS GUI RAID Manager: Introduction Provides password protection for guarding against unauthorized modification of disk array configuration. Provides Demo mode for use as a learning tool and for demonstration purposes. You can perform experimentation on various disk array configurations and monitor the performance of the system under such conditions. This Demo supports both the SCSI-to-SCSI and PCI-to-SCSI controllers. 1. 3 Feature Highlights This section explains in detail the important features of the GUI RAID Manager. 1. 3. 1 Graphical User Interface The GUI RAID Manager's graphical interface is based on the Windows specifications. [. . . ] 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.
