[. . . ] Remove the screws of the left and right panels. You will need them when replacing the panels. Slowly pull out both of the panels. 4. To reinstall the left and right panels, simply reverse the procedures discussed above. 22 Installing the Enclosure Frame 1. After removing the left and right panels, remove the screws located on the four corners of the enclosure. Gently pull out the entire frame to access the inside components. 2. To reattached the enclosure frame, simply reverse the procedures discussed above. 23 Chapter 5 Introduction Cluster Server Connection A cluster is a group of independent network servers that present themselves to a network as a single system. Often MIS administrator only manage a cluster as a single system. MSCS (Microsoft Cluster Server) clustering provides three main benefits: 1. Single device failure will not cause the service stopped.

Add more servers to increase the capacity of the cluster 24 3. Centralized administration. The administration of applications and services is centralized through the use of CLUSTER ADMINISTRATOR. Cluster solution for AcerAltos Server You can use the two AcerAltos servers, one hub and the cluster cable kits of Acer's cluster to build up the cluster environment, and then setup the MSCS by using the Microsoft Windows NT server 4. 0, Enterprise Edition. . . . . . . . . . . . . . . . . . . . . . . . .

The proper connection of the cable and pin layout is shown below. 12345 6789 32 b) The following are guidelines on using the serial port: · The serial port's default is set at 9, 600 baud, 8 bits, 1 stop bit and no parity. In most cases, connecting RD, TD and SG are enough to establish communication with a terminal. If you are using a PC as a terminal, any VT-100 terminal emulation software will suffice. Microsoft Windows includes a terminal emulation program as presented with the "T" terminal" icon in the Accessories window. · · 4. Building a RAID System Drive. The following figure is a basic flowchart when configuring a RAID system. Hardware installation must be completed before any configurations take place. Create Logical Drive Partition Logical Drive Map Host LUN (System Drive) When power is turned on, the AcerAltos 3102RS RAID box scans all the hard drives that are on all the drive channels. If a hard drive was connected after the controller completes initialization, use the "SCAN SCSI DRIVE" function to let the controller recognize the newly added hard drive and configure it as a member of a logical drive or a spare drive. In accordance to your requirement, configure a logical drive to contain one or more hard drives based on the desired RAID level, and partition the logical drive into one or several partitions. Map each partition as one system drive (LUN). The host SCSI adapter will recognize the system drives after re-scanning the host SCSI bus. 33 Since the controller is totally operating system independent, the operating system of the host computer will not be able to find out whether the attached devices are physical hard drives or virtual system drives created by the RAID controller. A `Logical Drive" is a set of drives grouped together to operate under a given RAID level and appears as a single contiguous drive. [. . . ] What is remarkable is that all of these failure recovery procedures are transparent to the host system. The controller has been designed with ease of integration and maintenance in mind. All major factors are described in the next chapter. The AA-3102RS already includes all the major operational requirements of the RAID sub system. [. . . ]
