    Architecture of the Compaq ProLiant Clusters HA/F100 and HA/F200 1-11 Private or Public Interconnect There are two types of interconnect paths: A private interconnect (also known as a dedicated interconnect) is used solely for intracluster (node-to-node) communication. Communication to and from network clients does not occur over this type of interconnect.

  • Page 25: Redundant Interconnects

    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.

    2-4 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Example 1: File & Print/File & Print An example business scenario (Figure 2-1) 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 39 Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-5 Example 2: Database/Database Another scenario (Figure 2-2) 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 40 2-6 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Example 3: File & Print/Database In this example (Figure 2-3), a business uses a single server to run its order entry department. The same department has a file and print server. While order entry is business-critical and requires maximum availability, the file and print server can be unavailable for several hours without impacting revenue.
  • Page 41 Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-7 If the node running the order entry database encounters a failure, the database fails over to its secondary node.

However, to obtain the most benefit while minimizing cost and complexity, view cluster communications as a single entity.
  • Page 52 2-18 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide Example 1 A Compaq dual-port NIC and a single-port NIC are used in this example (Figure 2-9).

The single-port NIC is configured as the primary network path for cluster-to-LAN communication.

  • Page 54 RAID Array 4100 storage system is the mechanism with which ProLiant Clusters implement shared storage. Generally, the storage system consists of a host bus adapter in each server, a storage hub or switch, a Compaq StorageWorks RA4000 Controller, and a Compaq StorageWorks RAID Array 4000 or Compaq StorageWorks RAID Array 4100 (RA4000/4100) into which the SCSI disks are placed.

  • Page 58 2-24 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide The Compaq ProLiant Cluster HA/F200 further enhances high availability through the use of additional, redundant, components in the server-to-storage connection and in the shared storage system itself. In the event of a failure, processing is switched to an alternate path without affecting applications and end users.
  • Page 59 Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-25 A storage hub, switch, or cable failure will be treated like a host bus adapter failure and a failover to the second host bus adapter, which is using a different storage hub and cables, will occur.
  • Page 60 2-26 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide The RA4000/4100 storage system has active data paths and standby data paths, separated by two Fibre Channel storage hubs or FC-AL switches. Figure 2-14 and Figure 2-15 detail the active and standby paths of the minimum HA/F200 configuration.
  • Page 61 RA4000/4100. If this path fails, the applications can seamlessly fail over to the standby hub-to-RA4000/4100 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.

  • Page 62: Capacity Planning

    2-28 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 63: Server Capacity

    Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-29 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 69: Static Load Balancing

    There are two means of static load balancing. One way balances a system’s workload across the cluster. The other balances a server’s workload across multiple data paths. The dual redundant loop of the Compaq ProLiant Cluster HA/F200 and an added RA4000/4100 storage system spread a system’s applications and data across the data paths through an active/active...

This configuration can accommodate static load balancing because the host bus adapters of one server can be in an active/active HBA mode to different storage systems.

  • Page 71: Networking Capacity

    Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-37 Networking Capacity The final capacity planning section addresses networking. The cluster nodes must have enough network capacity to handle requests from the client machines and must gracefully handle failover/failback events. Make sure both nodes can handle the maximum number of clients that can attach to the cluster.

  • Page 73 Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-39 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.

    2-40 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide 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.
