HP TruCluster Server V5.1 - World Wide QuickSpecs

Overview

HP TruCluster Server V5.1

HP TruCluster Server Version 5.1 for HP Tru64 UNIX Version 5.1, the next generation in the TruCluster product line from HP, provides highly available and scalable solutions for mission-critical computing environments. TruCluster Server delivers powerful but easy-to-use UNIX clustering capabilities.
TruCluster Server is an efficient and reliable platform for providing services to networked clients. To a client, the cluster appears to be a powerful single-server system; a client is impacted minimally, if at all, by hardware and software failures in the cluster.
By combining the advantages of symmetric multiprocessing (SMP), distributed computing, and fault resilience, a cluster running TruCluster Server offers high availability while providing scalability beyond the limits of a single system. On a single-system server, a hardware or software failure can severely disrupt a client's access to critical services. In a TruCluster Server cluster, a hardware or software failure on one member system results in the other members providing these services to clients.
By extending single-system management capabilities to clusters, TruCluster Server reduces the effort and complexity of cluster administration. It provides a clusterwide namespace for files and directories, including a single root file system that all cluster members share. A common cluster address (cluster alias) for the Internet protocol suite (TCP/IP) makes the cluster appear as a single system to its network clients while load balancing client connections across member systems.
A single system image allows a cluster to be managed more easily than distributed systems. TruCluster Server cluster members share a single root file system and common system configuration files. Therefore, most management tasks need to be done only once for the entire cluster rather than repeatedly for each cluster member. The cluster can be managed either locally from any of its members or remotely using Tru64 UNIX Web-based management tools. Tru64 UNIX and TruCluster Server software, and applications, are installed only once. Most network applications, such as the Apache Web server, need to be configured only once in the cluster and can be managed more easily in a cluster than on distributed systems.
A choice of graphical, Web-based, or command-line user interfaces makes management tasks easier for the administrator, flexible for those with large configurations, and streamlined for expert users.

TruCluster Server facilitates deployment of services that remain highly available even though they have no embedded knowledge they are running in a cluster. Applications can access their disk data from any cluster member. TruCluster Server also provides the support for components of distributed applications to run in parallel, providing high availability while taking advantage of cluster-specific synchronization mechanisms and performance optimizations.
TruCluster Server allows the processing components of an application to concurrently access raw devices or files, regardless of where the storage is located in the cluster. Member-private storage and clusterwide shared storage are equally accessible to all cluster members. Using either standard UNIX file locks or the distributed lock manager (DLM), an application can synchronize clusterwide access to shared resources, maintaining data integrity.
TruCluster Server simplifies the mechanisms of making applications highly available. A cluster application availability (CAA) facility records the dependencies of, and transparently monitors the state of, registered applications. If a hardware or software failure prevents one member from running a service, the failover mechanism automatically relocates the service a surviving member in the cluster, which maintains the availability of applications and data. Administrators can manually relocate applications for load balancing or hardware maintenance.
TCP-based and UDP-based applications can also take advantage of the cluster alias subsystem. These applications, depending on their specific characteristics, can run on a single cluster member or simultaneously on multiple members. The cluster alias subsystem routes client requests to any member participating in that cluster alias. During normal operations, client connections are dynamically distributed among multiple service instances according to administrator-provided metrics.

TruCluster Server supports a variety of hardware configurations that are cost-effective and meet performance needs and availability requirements. Hardware configurations can include different types of systems and storage units, and can be set up to allow easy maintenance. In addition, administrators can set up hardware configurations that allow the addition of a system or storage unit without shutting down the cluster.
TruCluster Server requires a PCI-based Memory Channel interconnect for fast and reliable communication between cluster members. Using multiple shared buses and redundant Memory Channel interconnects promotes no-single-point-of-failure (NSPOF) characteristics for mission-critical applications.

Features - TruCluster Server V5.1

A TruCluster Server cluster acts as a single virtual system, even though it is made up of multiple physical systems. Cluster members can share resources, data, and clusterwide file systems under a single security and management domain, yet they can boot or shut down independently without disrupting the cluster.

Cluster File System

The Cluster File System (CFS) makes all files, including the root (/), /usr, and /var file systems, visible to and accessible by all cluster members. It does not matter whether a file is stored on a device connected to all cluster members or on one that is private to a single member. Each file system is served by a single-cluster member; other members access that file system as CFS clients. CFS preserves full X/Open and POSIX semantics for file system access and maintains cache coherency across cluster members. For instance, an application can use standard UNIX file locks to synchronize access to shared files.

CFS supports the Advanced File System (AdvFS) along with NFS client and NFS servers for both read and write access. The UNIX File System (UFS), CD-ROM File System (CDFS), and Digital Video Disk File System (DVDFS) are supported for read access only. For higher performance, applications can use direct I/O through the file system to bypass the buffer cache.

Device Request Dispatcher

The device request dispatcher supports clusterwide access to character and block disk devices, and to tape and tape changer devices. All local and remote cluster disk and tape I/O passes through the device request dispatcher. A member does not need a direct connection to a disk, or tape, or tape changer device to access data on that device. This permits great flexibility in selecting a hardware configuration that is both economical and useful.

Cluster Alias

A cluster alias is an IP address that makes some or all cluster members look like a single system to clients and other hosts on the network. Cluster aliases free clients from having to connect to specific members for services. If the member providing the service goes down, the cluster alias subsystem automatically redirects client requests to a member running the service. With applications that run concurrently on multiple members, scaling is achieved by permitting multiple clients to connect to instances of the service on multiple cluster members.
The cluster alias subsystem provides an optional virtual MAC (vMAC) address that can be associated with each cluster alias IP address. When configured, the same MAC address is used in all Address Resolution Protocol (ARP) responses for the cluster alias address, independent of which cluster node is responding to cluster alias ARP requests. This permits faster failover when a new node assumes responsibility for responding to cluster alias ARP requests.

Cluster Application Availability Facility

The cluster application availability (CAA) facility delivers the ability to deploy highly available single instance applications in a cluster by providing resource monitoring and application relocation, failover, and restart capabilities. CAA is used to define which members can run a service, the criteria under which to relocate a service, and the location of an application-specific action script. Monitored resources include network adapters, tape devices, media changers, and applications. CAA allows services to manage and monitor resources by using entry points within their action scripts. Applications do not need to be modified in any way to utilize CAA.

Rolling Upgrade

TruCluster Server allows rolling upgrade from the previous version of the base operating system and TruCluster software to the next subsequent release of the base operating system and TruCluster software. It also allows the rolling of patches into the cluster. Updating the operating system and cluster software does not require a shutdown of the entire cluster. A utility is provided to roll the cluster in a controlled and orderly fashion. The upgrade procedure allows the monitoring of the status of the upgrade while it is in progress. Clients accessing services are not aware that a rolling upgrade is in progress.
See the TruCluster Server Software Installation manual for recommended and supported paths to upgrade to the latest version of TruCluster Server.

Cluster Management	The SysMan system management utilities provide a graphical view of the cluster configuration, and can be used to determine the current state of availability and connectivity in the cluster. The administrator can invoke management tools from SysMan, allowing the cluster to be managed locally or remotely.

Performance Management

The Performance Manager for Tru64 UNIX is a management application that monitors UNIX system performance information. A single instance of Performance Manager can monitor cluster and member systems and alert the user when problems arise. It monitors the cluster using the common cluster management information base (MIB) and TruCluster Server MIB.
The collect utility is a lightweight, highly flexible performance data collector that can run continuously 7x24 and manage its log files. For more information, see the collect(8) reference page.

Cluster MIB	TruCluster Server supports the HP Common Cluster MIB. The HP Insight Manager uses this Cluster MIB to discover cluster member relationships, and to provide a coherent view of clustered systems across supported platforms.

Highly Available NFS Server

When configured as an NFS server, a TruCluster Server cluster can provide highly available access to the file systems it exports. There are no special cluster management operations required to configure the cluster as a highly available NFS server. In the event of a system failure, another cluster member will become the NFS server for the file system, transparent to external NFS clients. NFS file locking is supported, as are both NFS V2 and V3 with UDP and TCP.

Fast File System Recovery

The Advanced File System (AdvFS) log-based file system provides higher availability and greater flexibility than traditional UNIX file systems. AdvFS journaling protects file system integrity. TruCluster Server supports AdvFS for both read and write access.
An optional, separately licensed product, the Advanced File System Utilities, performs online file system management functions. See the OPTIONAL SOFTWARE section of this document for more information on the AdvFS utilities.

Increased Data Integrity

Tru64 UNIX Logical Storage Manager (LSM) is a cluster-integrated, host-based solution to data storage management. In a TruCluster Server cluster, LSM operations continue despite the loss of cluster members, as long as the cluster itself continues operation and a physical path to the storage is available. LSM disk groups can be used simultaneously by all cluster members and the LSM configuration can be managed from any cluster member.
Basic LSM features, including disk spanning and concatenation, is provided with the Tru64 UNIX operating system. Extended features, such as striping (RAID 0), mirroring (RAID 1), and online management, are available with a separate license. Mirroring of LSM is RAID Advisory Board (RAB) certified for RAID Levels 0 and 1.
LSM is supported for use in a TruCluster Server cluster and will support any volume in a cluster except for the following: clusterwide root domain, quorum disk, member disks, and swap partitions.
LSM RAID 5 volumes are not supported in clusters. See the OPTIONAL SOFTWARE section of this document for more information on LSM.

Global Error Logger & Event Manager	TruCluster Server can log messages about events that occur in the TruCluster environment to one or more systems. Cluster administrators can also receive notification through electronic mail when critical problems occur.

Cluster Storage I/O Failover

TruCluster Server provides two levels of protection in the event of storage interconnect failure. When configured with redundant storage adapters, the storage interconnect will be highly available. Should one interconnect fail, traffic will transparently fail over to the surviving adapter. When a member system is connected to shared storage with a single storage interconnect and it fails, transactions are transparently performed via the cluster interconnect to another cluster member with a working storage interconnect.

Cluster Client Network Failover	TruCluster Server supports highly available client network interfaces via the Tru64 UNIX redundant array of independent network adapters (NetRAIN) feature.

Cluster Interconnect Failover

Memory Channel is a high-performance, PCI-based interconnect that cluster members use for passing low-overhead messages among themselves. TruCluster Server requires a PCI-based Memory Channel interconnect for fast and reliable communication between cluster members. When configured with redundant Memory Channel adapters, a cluster with no single point of failure can be configured to achieve high availability. The cluster can transparently fail over intercluster communication to the surviving adapter in the event that one fails.

Support for Parallelized Database Applications	TruCluster Server provides the software infrastructure to support parallelized database applications, such as Oracle Parallel Server (OPS) and Informix Extended Parallel Server (XPS) to achieve high performance and high availability. OPS and XPS are offered and supported separately by Oracle Corporation and Informix Software, Inc., respectively.

Distributed Lock Manager

The distributed lock manager (DLM) synchronizes access to resources that are shared among cooperating processes throughout the cluster. DLM provides a software library with an expansive set of lock modes that applications use to implement complex resource-sharing policies. DLM provides services to notify a process owning a resource that it is blocking another process requesting the resource. An application can also use DLM routines to efficiently coordinate the application's activities within the cluster.

Support for Memory Channel API	TruCluster Server provides a special application programming interface (API) library for high-performance data delivery over Memory Channel by giving access to Memory Channel data transfer and locking functions. This Memory Channel API library enables highly optimized applications that require high-performance data delivery over the Memory Channel interconnect. High performance within the cluster is achieved by providing user applications with direct access to the capabilities of the Memory Channel. For example, a single store instruction on the sending host is sufficient for the data to become available for reading in the memory of another host. The Memory Channel API library lets a programmer create and control access to regions of the clusterwide address space by specifying UNIX style protections. Access to shared data can be synchronized using Memory Channel spin locks for clusterwide locking. The Memory Channel API library facilitates highly optimized implementations of Parallel Virtual Machine (PVM), Message Passing Interface (MPI), and High Performance Fortran (HPF), providing seamless scalability from SMP systems to clusters of SMP machines. This provides a programmer with comprehensive access to the current and emerging de facto standard software development tools for parallel applications while supporting portability of existing applications without source code changes.
	NOTE: to users of the Memory Channel API V1.6 product on Tru64 UNIX Version 4.0: On Tru64 UNIX V5., the TruCluster Memory Channel Software V1.6 product is bundled as a feature of TruCluster Server V5.. To run the Memory Channel API library on Tru64 UNIX version 5.1, you must install Memory Channel hardware and a TruCluster Server license to configure a valid TruCluster Server cluster. NOTE:* to users of the Memory Channel application programming interface (MC API) with Memory Channel virtual hub (vhub) configuration: The Memory Channel API is not supported for data transfers larger than 8K bytes when loopback mode is enabled in two member clusters configured with MC virtual hub. For more information on loopback mode go to http://www.tru64unix.hp.com/docs/updates/TCR51A/TITLE.HTM and refer to the 21.Mar.2002 Technical Update titled "MC API Applications May Not Use Transfers Larger Than 8 KB with Loopback Mode Enabled on Clusters Utilizing Virtual Hubs". NOTE: This Web site is available in English only.

Connection Manager	The connection manager is a distributed kernel component that ensures that cluster members communicate with each other and enforces the rules of cluster membership. The connection manager forms a cluster, and adds and removes cluster members. It tracks whether members in a cluster are active and maintains a cluster membership list that is consistent on all cluster members.

Support for Fibre Channel Solutions	TruCluster Server supports the use of switched Fibre Channel storage and Fibre Channel Arbitrated Loop. Fibre Channel provides the following benefits over parallel SCSI storage:
	Greater performance Greater scalability More reliability, serviceability, and availability
	Fibre Channel can be used for clusterwide shared storage, cluster file systems, swap partitions, and member boot disks. Compared to parallel SCSI storage, Fibre Channel is easier to configure and its long distance permits greater flexibility in configurations. Compared with a switched Fibre Channel topology, Arbitrated Loop offers a lower cost solution by trading off bandwidth, and therefore some performance. Arbitrated Loop is supported for two-member configurations only. For more information on supported TruCluster Server configurations and specific cabling restrictions using Fibre Channel, see the TruCluster Server Hardware Configuration manual at the following URL: http://tru64unix.compaq.com/docs/pub_page/cluster_list.html
	NOTE: This Web site is available in English only.

Enhanced Security with Distributed Authentication	TruCluster Server supports the ability to enable the Enhanced Security option on all cluster members. This includes support for features for enhanced login checks and password management. Audit and access control list (ACL) support can also be enabled independently of the Enhanced Security option on cluster members.

Supported Tape Devices and Media Changers	TruCluster Server supports the configuration of specific tape devices on a shared SCSI bus and on Fibre Channel. These devices will function properly in a multi-initiator environment. On a SCSI bus, they will be disrupted by bus resets that occur during cluster membership change events. Backup software must be explicitly capable of handling and recovering from such events and must utilize the cluster application availability (CAA) facility to facilitate highly available backup.
