Dell™ PowerEdge™ Cluster F-Series SAN Guide This document supplements the information in the Dell PowerEdge Cluster FE100/ FL100 Installation and Troubleshooting Guide and the Dell PowerVault™ storage area network (SAN) documentation for using Dell PowerEdge Cluster F-Series configurations running Microsoft® Cluster Server (MSCS) and Microsoft Windows® 2000 Cluster Service software in conjunction with Dell PowerVault SAN 3.0.
PAGE 8
The following options are available for PowerEdge Cluster F-Series configurations: • • • Direct-attached cluster SAN-attached cluster Cluster consolidation The following sections provide detailed information and examples for these options. Direct-Attached Cluster In a direct-attached cluster configuration, both nodes of the cluster are directly attached to a single PowerVault 65xF storage system. NOTE: A direct-attached cluster configuration does not require a SAN.
PAGE 9
Zoning helps to segment a SAN into logical fabric subsets by setting up barriers between different operating environments, or between a cluster and other servers or clusters. By using switch zoning, you can attach multiple clusters to a SAN. See the Dell PowerVault 5xF Switches Zoning Guide for information on zoning concepts and implementations. Figure 1-2 shows an advanced SAN-attached cluster configuration.

SAN-Attached Clusters SAN-attached clusters are cluster configurations in which you cable redundant Fibre Channel HBAs to a redundant Fibre Channel switch fabric. You make the connection to the storage system through the switch fabric. SAN-attached configurations can share certain resources with other servers, storage systems, and backup systems on the SAN. Figure 1-4 shows how a SAN-attached PowerEdge Cluster F-Series configuration uses three networking segments: public network, private network, and SAN.
PAGE 12
• Storage area network (SAN) — A configuration of computer and storage systems that incorporates dedicated Fibre Channel connectivity between the computer systems and storage. A SAN bypasses traditional network bottlenecks and supports direct high-speed data transfer between the servers and storage devices. SAN-Attached Cluster Rules and Guidelines The following rules and requirements described in Table 1-1 apply to SAN-attached clusters.
PAGE 13
Table 1-1. Rules and Guidelines for SAN-Attached Clusters (continued) Rule/Guideline Description Fibre Channel switches supported PowerVault 50F, 51F, and 56F. Fibre Channel switch firmware For 50F, version 1.6d5-dell or later; for 51F and 56F, version 2.1.7 or later. Fibre Channel HBA supported QLogic 2100/33, 2200/33, or 2200/66 megahertz (MHz) HBA (copper cabling). HBAs within a single cluster must be the same. QLogic driver version Version 7.04.08 or later for Windows NT. Version 7.04.
PAGE 14
Cluster Installation Overview This section provides an overview sequence for installing PowerEdge Cluster F-Series systems with Windows NT 4.0 Server, Enterprise Edition or Windows 2000 Advanced Server operating systems. More detailed instructions are provided later in this document. NOTICE: Before installing the cluster, ensure that your site can handle the power requirements of the cluster equipment. Contact your Dell sales representative for information about your region’s power requirements.
PAGE 15
7. Install Windows NT Service Pack 6a or later. See the Dell PowerEdge Cluster FE100/FL100 Platform Guide for more information on the latest supported service pack. 8. Install the miniport driver for the Fibre Channel HBAs in each node. 9. Install the QLogic Fibre Channel configuration utility. 10. Install Dell OpenManage Application Transparent Failover (ATF) on each node and reboot. 11. Install Dell OpenManage Managed Node (Data Agent) on each node. 12.
PAGE 16
3. If you are using hardware-based RAID for the internal SCSI hard-disk drives, configure them using the controller's BIOS utility. 4. Perform the low-level configuration of the HBAs. 5. Install and configure the Microsoft Windows 2000 Advanced Server operating system on each node and the latest Windows 2000 Service Pack. See the Dell PowerEdge Cluster FE100/FL100 Platform Guide for more information on the latest supported service pack. 6.
PAGE 17
18. Install Dell OpenManage Cluster Assistant With ClusterX from the management console (optional). 19. Record the configuration of the cluster on the cluster data sheets provided in the Dell PowerEdge Cluster FE100/FL100 Installation and Troubleshooting Guide. Using Dell PowerVault Fibre Channel Switches You can connect cluster nodes to the PowerVault 65xF shared storage system by using redundant PowerVault Fibre Channel switches.

2. Assign drive letters and volume labels to the disks. a. Turn off node A. b. Assign the drive letters on node B by using the Windows NT Disk Administrator or Windows 2000 Disk Management utility to create the drive letters and volume labels. For example, create volumes labeled "Volume E" for disk E and "Volume F" for disk F. c. Turn off node B. Turn on the node A, and start the Windows NT Disk Administrator or Windows 2000 Disk Management utility. d. Assign the drive letters on node A.
PAGE 23
NOTE: Using zoning in SAN configurations containing multiple MSCS clusters prevents the nodes from discovering a storage device that belongs to another cluster. For example, cluster nodes 1 and 2 that connect to shared storage system A should not “see” shared storage B to which nodes 3 and 4 are connected. Zoning prevents this scenario, while allowing all of the nodes to see the tape backup devices.

Figure 1-14 shows a configuration with five MSCS clusters sharing a single PowerVault 65xF storage system. These five MSCS clusters also share the two PowerVault 130T tape libraries through the SAN with the use of the PowerVault 35F Fibre Channel bridge. This configuration requires two PowerVault 56F, 16-port Fibre Channel switches and the creation of five zones. Each zone contains an individual two-node MSCS cluster (both servers), the Fibre Channel-to-SCSI bridge, and the PowerVault 65xF storage system.
PAGE 36
Figure 1-15 shows a configuration with ten MSCS clusters sharing a single PowerVault 65xF storage system. These ten MSCS clusters also share the two PowerVault 130T tape libraries through the SAN with the use of the PowerVault 35F Fibre Channel bridge. This configuration requires four Fibre Channel switches and the creation of ten zones. Each zone contains an individual two-node MSCS cluster (both servers), the Fibre Channel-to-SCSI bridge, and the PowerVault 65xF storage system.
PAGE 37
Figure 1-16 shows a configuration with six MSCS clusters. Clusters one through four share a single PowerVault 65xF storage system, cluster five has its own storage system, and cluster six uses four storage systems. All six MSCS clusters also share the two PowerVault 130T tape libraries through the SAN with the use of the PowerVault 35F Fibre Channel Bridge. This configuration requires four PowerVault 56F, 16-port Fibre Channel switches and the creation of six zones.
