10/100 NICs and redundant hot-pluggable power supplies (on most high-end models). Many of these features are available at the low end and mid range of the Compaq ProLiant server line, as well. Compaq has logged thousands of hours testing multiple models of Compaq servers in clustered configurations and has successfully passed the Microsoft Cluster Certification Test Suite on numerous occasions.
Page 20 The RA4000 can hold twelve 1-inch or eight 1.6-inch Wide-Ultra SCSI drives. The RA4000 supports the same hot-pluggable drives as Compaq Servers and Compaq ProLiant Storage Systems, online capacity expansion, online spares, and RAID fault tolerance of SMART-2 Array Controller technology.
Page 21: Compaq Storageworks Fibre Channel Storage Hubs
7-port and 12-port hubs may be combined, if desired. If the maximum number of supported RA4000s (currently five) are connected to either type of cluster using a 12-port hub, there will be unused ports. Compaq does not currently support using these ports to connect additional RA4000s. Other FC-AL capable devices such as tape backup systems should not be connected to these unused ports under any circumstances.
Page 22: Compaq Storageworks Fibre Channel Host Adapter
Compaq ProLiant Cluster HA/F100. At least four host bus adapters (PCI only), two for each cluster node, are required in the HA/F200 configuration. For more information about this product, refer to the Compaq StorageWorks Fibre Channel Host Adapter Installation Guide. Gigabit Interface Converter-Shortwave Two Gigabit Interface Converter-Shortwave (GBIC-SW) modules are required for each Fibre Channel cable installed.
Page 23 Architecture of the Compaq ProLiant Clusters HA/F100 and HA/F200 1-11 Cluster Interconnect Two types of cluster interconnect cables may be used depending on the type of devices used to implement the interconnect, and whether the interconnect is dedicated or shared: 1.
Page 24: Cluster Interconnect
1-12 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Cluster Interconnect The cluster interconnect is a data path over which nodes of a cluster communicate. This type of communication is termed intracluster communication. At a minimum, the interconnect consists of two network adapters (one in each server) and a cable connecting the adapters.
Page 25: Interconnect Adapters
There are two ways to achieve this, and the method you choose is dependent on your hardware. One way is through use of the Redundant NIC Utility available on all Compaq 10/100 Fast Ethernet products. The other option is through the use of the Network Fault Tolerance feature designed to operate with the Compaq 10/100 Intel silicon-based NICs.

Page 33: Planning Considerations
The items detailed in this section will help you design your Compaq ProLiant Cluster so that it addresses your specific availability needs.
Page 34 Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-3 An active/active configuration has two primary designs: The first design uses Microsoft Cluster Server (MSCS) failover capabilities on both nodes, enabling Node1 to fail over clustered applications to Node2 and enabling Node2 to fail over clustered applications to Node1.
Page 35: Active/Active Example
2-4 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Example 1: File & Print/File & Print An example business scenario involves two file and print servers. The Human Resources (HR) department uses one server, and the Marketing department uses the other. Both servers actively run their own file shares and print spoolers while the cluster is in its normal state (an active/active design).
Page 36 Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-5 Example 2: Database/Database Another scenario has two distinct database applications running on two separate cluster nodes. One database application maintains Human Resources records, and its primary node is set to the HR database node. The other database application is used for market research, and its primary node is set to the Marketing database node.
Page 37: Active/Standby
2-6 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide If the node running the order entry database encounters a failure, the database fails over to its secondary node. The order entry clients experience a slight disruption of service while the database resources are failed over, the database transaction log is rolled back, and the information in the database is validated.

Page 55 2-24 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide HA/F200 Fibre Channel Data Paths The Compaq StorageWorks RAID Array 4000 storage system is the mechanism with which the HA/F200 cluster implements shared storage. The Compaq ProLiant Cluster HA/F200 minimum configuration consists of two host bus adapters in each server, two 7- or 12-port storage hubs, two array controllers per RA4000, and one or more RA4000s.
Page 56: Hub To Ra4000 Data Path
The dual redundant loop feature of the Compaq ProLiant Cluster HA/F200 increases the level of availability over clusters that have only one path to the shared storage. In addition, the second loop in the HA/F200 provides for improved performance through load balancing.
Page 57: Capacity Planning
2-26 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Capacity Planning Capacity planning determines how much computer hardware is needed to support the applications and data on your clustered servers. Unlike conventional, single-server capacity planning, clustered configurations must ensure that each node is capable of running any applications or services that may fail over from its partner node.
Page 58: Server Capacity
Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-27 Determine the processor and memory requirements needed to support the clustered applications and services that will run on each node while the cluster is in a normal operating state. If the program files of a clustered application and/or service will reside on local storage, remember to add that capacity to the amount of local storage needed on each node.
Page 59: Server Capacity

Page 65: Network Considerations
2-34 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Network Considerations This section addresses clustering items that affect the corporate LAN. MSCS has specific requirements regarding which protocol can be used and how IP address and network name resolution occurs. Additionally, consider how network clients will interact within a clustering environment.
Page 66: Migrating Network Clients
Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-35 DHCP Only use DHCP for the clients; it should not be used for the cluster node IP addresses or cluster resource IP addresses. DHCP cannot be used to assign IP addresses for virtual servers.
Page 67: Connecting To
2-36 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Connecting to Shared Resources In the traditional, command-driven connection to a shared resource, the user needs to know the server name and the share name. In a clustered environment, the command is changed to reflect the cluster network name and file share that were configured as part of the failover group for that shared directory.
Page 68: Failover/Failback Planning
Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-37 In a clustered environment, IP addresses for the database are configured to fail over with the database application, making a backup IP address on the client unnecessary. When the database resources have failed over to the other server, the client can reconnect to the database using the same IP address as before the failure.
Page 69: Mscs Thresholds And Periods
2-38 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide You can use the Windows NT Performance Monitor to observe and track system performance. Some applications may also have their own internal performance measurement capabilities. MSCS Thresholds and Periods MSCS offers flexibility in configuring the initiation of failover events. For resources, MSCS allows you to set Restart Thresholds and Periods.

Page 77 Controller (BDC), or they can both be a BDC in an existing Windows NT domain. One of the utilities the SmartStart CD runs is the Compaq Array Configuration Utility, which configures the drives in the RA4000. The Array Configuration Utility stores the drive configuration information on the drives themselves.
Page 78 Setting Up the Compaq ProLiant Clusters HA/F100 and HA/F200 3-5 MSCS requires drive letters to remain constant throughout the life of the cluster; therefore, you must assign permanent drive letters to your shared drives. If you are performing manual software installation, use Windows NT Disk Administrator to assign drive letters and ensure the assignments are permanent.
Page 79: Installing The Hardware
IMPORTANT: Do not load any software on either cluster node until all the hardware has been installed in both cluster nodes. NOTE: Compaq recommends that Automatic Server Recovery (ASR) be left at the default values for clustered servers. Follow the installation instructions in your Compaq ProLiant Server documentation to set up the hardware.
