18 18 PureDisk Remote Office Edition (ROE) installation overview Types of storage pools wwwnovellcom/documentation/sles10 See About PureDisk installations on page 13 Types of storage pools Table 1-2 explains the characteristics of different PureDisk storage pools Table 1-2 Type of storage pool Types of storage pools Description An all-in-one, single-node storage pool A multinode, unclustered storage pool In an all-in-one storage pool, there is only one node During the installation process, you first install PDLinux on the one node Later, you configure the PureDisk application to run on the node The installation process puts all PureDisk services on the single node This kind of a storage pool is not highly available, so no clustering software is included in the installation In a multinode storage pool, PureDisk services are installed on two or more nodes During the installation process, your first step is to install PDLinux on each node In a storage pool, you can have only one storage pool authority service, but you can have more than one instance of the other PureDisk services You need to plan the services you want to configure on each node When you run the Storage Pool Configuration Wizard, make sure to start the wizard from the node that you want to designate as the storage pool authority The Storage Pool Configuration Wizard installs the PureDisk application on each node, and creates PureDisk services on each node A clustered storage pool A clustered storage pool is a highly available multinode storage pool The failover feature guarantees that the storage pool is always up and running The Veritas Cluster Server (VCS) software ensures that the cluster can failover The PureDisk Storage Pool Configuration Wizard installs the VCS software for you automatically during the wizard session The Storage Pool Configuration Wizard prompts you to designate some nodes as active nodes and to designate other nodes as passive nodes These nodes are as follows: An active node hosts PDLinux and other PureDisk services A passive node hosts PDLinux but no other services During a failover, a passive node receives services from a failing node You need at least one passive node in a highly available storage pool

19 PureDisk Remote Office Edition (ROE) installation overview Types of storage pools 19 You can add additional nodes to any kind of storage pool if your processing needs change You cannot, however, transform an unclustered storage pool into a clustered storage pool Clustering must be enabled when you create the storage pool In an unclustered storage pool, the nodes cannot failover in case of a disaster When you configure this kind of storage pool, the Storage Pool Configuration Wizard does not display the clustering pages to you during your configuration session Figure 1-2 shows an unclustered two-node storage pool example and shows the services that reside on both nodes Figure 1-2 An unclustered two-node storage pool Node 1: Storage pool authority Metabase server Node 2: Content router Metabase engine NetBackup Export Engine Figure 1-3 shows a clustered three-node storage pool and shows the services that reside on the nodes

20 20 PureDisk Remote Office Edition (ROE) installation overview Types of storage pools Figure 1-3 A clustered three-node storage pool Node 1: Storage pool authority Metabase server Metabase engine Content router Node 2: Content router Metabase engine NetBackup export engine Three network connections per node: One connects the cluster to the public network Two others form the private heartbeat monitor Node 3: Passive node

21 PureDisk Remote Office Edition (ROE) installation overview About third-party components 21 In Figure 1-3, the first node is an all-in-one system The second node hosts an extra content router, an extra metabase engine, and a NetBackup export engine The third node is a passive node See About PureDisk installations on page 13 About third-party components PureDisk uses third-party components as a part of its architecture The following warning message explains how to administer the software in a PureDisk storage pool with regard to these third-party components Warning: PureDisk uses third-party components as part of its architecture As an administrator, you should not upgrade third-party components to a newer version; doing so may affect your ability to obtain support from Symantec Symantec monitors the releases of these third-party components Symantec also provides upgrades and patches to address vulnerability, performance, and stability problems that can affect the software The Linux operating system is part of the PureDisk software and is based on the standard SUSE Linux operating system by Novell Symantec removed some packages from the SUSE Linux installation and added some packages to make Linux suitable for the appliance platform A complete list of Linux packages contained in the PureDisk software, as well as the source code for such packages, is available from Symantec upon request Do not install additional third-party software on the computers in a PureDisk storage pool Any such installation is an unsupported activity Such installations can cause service interruptions and problems with product stability See About PureDisk installations on page 13
