10 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 10 July 2006 Serviceguard for Linux (SG/LX) Single Cluster up to 16 nodes –2 to 4 nodes with Proliant servers using SCSI –Up to 16 nodes with Integrity servers or ProLiant servers using FibreChannel For use when all nodes are in a single Data Center Automatic failover –up to 150 application packages (up to 900 services total) –supports up to 200 relocatable package IP addresses per cluster SCSI or Fibre Channel for disks Single IP subnet for each heartbeat network (IPv4) –Multiple heartbeat networks required (at least 2) Ethernet, supporting up to 7 Heartbeat subnets Network bonding for automatic network failover File System and Volume Manager –reiser, XFS, and ext3 file systems (Journaled file systems) –Logical Volume Manager (LVM and LVM2) that is included in the Linux distribution –RedHat Global File System (GFS) Dynamically loadable modules for Serviceguard installation Quorum Device Required for 2-node clusters, optional for larger clusters –Quorum Service with up to 16 nodes –Cluster Lock LUN for up to 4 nodes only

11 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 11 July 2006 Multi-pathing Solutions Multi-pathing solutions for HP-UX –LVM/SLVM – PVLinks (active/standby) –VxVM/CVM – DMP (dynamic multi-pathing, active/active) –StorageWorks disk arrays (XP and EVA) – SecurePath (active/active) –EMC disk arrays (Symmetrix and DMX) – PowerPath (active/active) Multi-pathing solutions for Linux –FibreChannel HBA FibreChannel driver StorageWorks disk arrays – SecurePath EMC disk arrays – PowerPath –SCSI Linux md driver

12 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 12 July 2006 OS differences impacting SG functionality Extended / Campus Cluster is not supported on Linux –md implementation currently does not meet robustness requirements Data integrity protections are not as robust with Sistina LVM (Linux) –Manual activation of a volume used by an SG/LX package from another server can corrupt data –HP-UX volume managers support exclusive activation mode to protect against inadvertent activation from another server inside or outside of the cluster NFS fail over does not include file locks on Linux –Correcting requires Linux kernel changes –NFS v4 plans to support lock fail over and need distribution vendors to support it NOTE: Consider CFS or GFS instead of HA NFS.

13 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 13 July 2006 SG cluster (local cluster – shared connectivity) All systems are physically connected to each disk Maximum cluster size is 16 nodes Each application runs on only one host at a time Hosts can run multiple applications Failover is possible to any node that is physically connected to the data App AApp BApp CApp D A B C D Cluster Lock 2-node cluster Quorum Service Highly Available Quorum Device that is not a member of the cluster whose quorum is being satisfied

14 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 14 July 2006 Failover Models Active / Standby –One or more nodes are reserved for failover use –Upon failover, the applications maintain performance due to spare capacity Active / Active –All nodes are running (different) applications –Upon failover, choice of Reduced capacity when multiple applications run on the same node Shutdown less critical applications Optional use of VSE technologies to guarantee resource entitlements Rotating Standby –Upon failover, the standby system becomes the new production system and the repaired system becomes the new standby system Active / Active (distributed application) –All nodes are running an instance of the same application (e.g., RAC) –Depends on shared read/write access to the data –No failover of the application –Upon failure of a node (or instance), the users are sent to the remaining nodes

15 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 15 July 2006 SG cluster – preventing split brain App AApp BApp CApp D A B C D Each sub-cluster tries to form a cluster and run all of the applications Two instances of the same application write to the same disks, resulting in data corruption App A

16 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 16 July 2006 SG cluster – preventing split brain (continued) App AApp BApp CApp D A B C D Cluster Lock 2-node cluster Quorum Service Highly Available Quorum Device that is not a member of the cluster whose quorum is being satisfied Each sub-cluster tries to acquire the cluster lock on the cluster lock disk/lock LUN The algorithm guarantees that only one sub- cluster will get it One sub-cluster is forced to crash to prevent data corruption

17 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 17 July 2006 Quorum Service (QS) (HP-UX and Linux) Alternative quorum arbitration method Supports up to 50 clusters and maximum of 100 nodes TCP/IP network connection required (Not required to be in the same subnet, although recommended to minimize network delays) Stand-alone HP-UX or Linux-based server(s) outside of the Serviceguard cluster whose quorum is being satisfied Runs as a real-time process The Quorum Service (QS A.02.00) can be configured in a package in a cluster cannot reside in the same cluster that uses it do not configure two clusters that use the same Quorum Service package Bonding (Linux) or APA (HP-UX) can be used to increase network availability to the Quorum Service

19 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 19 July 2006 What is the SG Cluster File System? True multi-reader / multi-writer CFS –Applications on different nodes within the cluster can access the same files simultaneously –Similar to distributed raw volumes in SG today, except with file systems –Applications are responsible to ensure that simultaneous access does not result in application (logical) data corruption Does provide locking functions with POSIX file system locking semantics (lockf, similar to multiple users accessing the same file on a single system) –POSIX file system semantics are advisory only –Locks can refer to regions of a file

20 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 20 July 2006 Storage Options in a Serviceguard Cluster A cluster file system is concurrently accessed by all cluster nodes. A failover file system is exclusively activated by one node and can transition between nodes. /project /proj2 /proj1 Local Root /mnt1 VxFS /mnt2 VxFS CFS Storage VxFS Raw Volume Cluster Node A Cluster Node B A raw volume can be exclusively activated and failed over OR concurrently accessed

21 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 21 July 2006 VEA manages CFS mount points and VxVM and CVM volumes In HP-UX 11iv3 (11.31), we expect that fsweb will launch VEA Management GUI VERITAS Enterprise Administrator (VEA)

22 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 22 July 2006 Adoption of Serviceguard CFS Overall message: –No forced transition –Transition can occur in customers timeframe –LVM/SLVM will continue to be supported and enhanced –We dont expect all customers or ISVs to have a need for the CFS functionality Benefits of a CFS vary with the application and must be evaluated on a case-by- case basis There are targeted applications where we expect to see SG/CFS adoption ISVs will not need to re-certify with the new version of Serviceguard ISVs may want to take advantage of the CFS, and that may require development effort for: –Installation / configuration processes and scripts –Application-level locking when sharing data and files

30 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 30 July 2006 Serviceguard and Workload Manager Workload Manager (WLM) –WLM allows the specification of SLOs for SG packages that may not be active on the system. Each SLO is conditional on which server the package active – When a failover or package movement occurs, WLM detects it and enforces the SLO – the package gets the priority and the resources specified – WLM automatically activates/deactivates TiCAP processors to reduce the performance impact of an application failover in active-active single or multi-site disaster tolerant configurations – Using WLM on a Pay per use (PPU) basis reduces the cost of active- standby single or multi-site disaster tolerant configurations

68 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 68 July 2006 Protecting against split brain and data corruption ServiceGuard uses a tie-breaker or Quorum Device to prevent Split- Brain of the cluster –Cluster lock disk (HP-UX) or Cluster LUN (SG/LX) single cluster lock disk (when all servers are in a single data center) dual cluster lock disks (when the servers are distributed across two data centers) –Quorum Server a (small) server that is outside of the cluster Without a tie breaker, split-brain can occur when: –a network failure splits the cluster into 2 equal halves -OR- – exactly half of the servers in the cluster fail all at once Unless split-brain is prevented, data corruption will occur if the application runs concurrently on both halves of the cluster and modifies the same single copy of the data

70 Portions © Intel Corporation | Portions © Hewlett-Packard Corporation 70 July 2006 Cluster Lock Disk (HP-UX Only) Cluster Lock LUN (Linux Only) A special area on an LVM disk located in a volume group that is shareable by all nodes in the cluster When a node obtains the cluster lock, this area is marked so that other nodes will recognize the lock as taken. A cluster lock disk for HP-UX can be employed as part of a normal volume group containing user data Lock requirements – Usable for clusters between 2 and 4 nodes – Greater than four nodes – lock disk is not allowed; however a quorum service may be used Cluster Lock LUN Alternative to QS Similar to SG lock disk (on HP-UX) Requires exclusive use of a single LUN (Linux partition of size 100K) Cluster Lock Disk
