[. . . ] 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. . . . . . . . . . . . . . . . . . . . . . . . .

Two AcerAltos Servers + AcerAltos RS700 RAID Storage. AcerAltos 3102RS RAID Box supporting three Ultra SCSI Channels: One for host channel, and two for drive channels. Built-in SCSI Expander on RS700 RAID storage. 4. Support up to two AcerAltos RS700 RAID storage units. The cabling length of the SCSI host bus can be up to 12 meters.

Ensure that you have got the all of the hardware requirements of Acer's cluster server, and refer to the architecture of Acer's Cluster to build up the cluster. Connect the private network between two nodes by using the STP crossover cable. You must insert another NIC on each node and connect them to the Public Network (Hub). Connect the External SCSI Cables between two Hosts and the AcerAltos RS700. 2. 3. 4. Hardware Configuration 1. Host configuration a) Power on each AcerAltos Server and press <Ctrl>+<A> for the SCSISelectTM Utility when the screen shows this message: "Adaptec AIC-7880 Ultra/Ultra W BIOS V 1. x". Click the "Configure/View Host Adapter Setting" and choose the SCSI channel 1(which connects to the AcerAltos RS700). Enable the Host Adapter SCSI Termination function. Enable the Multiple LUN Support function in the Advanced Configuration options. Set the host's SCSI ID to 6 for SCSI channel 1 of Host 1. Set the host's SCSI ID to 7 for SCSI channel 1 of Host 2. b) c) d) e) 31 2. Configuring the RAID Box. It is very important to configure the RAID Box to create Acer's cluster server. [. . . ] The overall features of a fully-built RAID system will, however, depend on the actual components used and the creativity of the integrator. Basic Features · Five operating modes: · · · · · Non-RAID RAID-0 RAID-1 RAID-3 RAID-5 Disk-spanning Disk striping Disk mirroring and striping (RAID 0+1) Disk striping with dedicated parity Multiple block striping with interspersed parity 59 · Comprehensive failure management including: · · · · · Automatic bad sector reassignment Hot-swapping Spare drive operation (supports both global spare and local spare) Background rebuilding (rebuild priority selectable) Verify-after-write supported on normal writes, rebuild writes and/or RAID initialization writes · · · · · · · · · · · · · · · Works with any operating systems without additional software drivers 5. 25" drive profile allows easy integration into external subsystem enclosures directly into the host system's drive bay Up to five drive channels (optional 3-channel upgrade) for a total of 75 connected drives Supports up to 15 SCSI IDs per channel Up to 8 logical drives, each with independent RAID modules Up to 8 partitions per logical drive Dynamic mapping of LUNs to logical drives. Two or more LUNs can be mapped to the same logical drive for redundant host operation Performance optimization for Sequential or Random I/O Allows multiple drive failure and concurrent multiple drive rebuild of a RAID (0+1) logical drive Two or more SCSI channels can be simultaneously set as host interface for redundant host system operation EDO DRAM supported for enhanced performance Up to 128 Mbytes of intelligent Read-Ahead/Write-Back cache with optional battery backup Optional battery backup module to protect data in Write-Back cache when a power failure occurs Front panel LCD and push buttons for configuration and message display Acer RAID Manager and RS-232 terminal interface for RAID management 60 · Supports Fault-bus for enclosure management Channel Connection Setup Table Channel # CH0 Host/Drive Channel Host ID# 0 Terminator On Connection Connect to the SCSI expansion slots and ready to connection with the host server Connect to the first 3 drive trays Connect to the last 4 drive trays CH1 CH2 Drive Drive 7 7 On On 61 Appendix B SCSI Expander SCSI Expander (EP-SL) Single-ended and Low Voltage Differential signals are incompatible at the electrical level: however, you can use a converter to change the signals. The SCSI Expander is an extension and a converter card for SCSI devices. It converts Single-Ended (SE) electrical signal type to Low Voltage Differential (LVD) electrical signal type extending the limited cable length of SE signals. [. . . ]
