  • Page 17: Arrays

    • Include the appropriate number of physical drives in the arrays to create logical storage elements of desired sizes. Arrays Figure 2. With an array controller installed in the system, the capacity of several physical drives (P1–P3) can be logically combined into one or more logical units (L1) called arrays. When this is done, the read/write heads of all the constituent physical drives are active simultaneously, dramatically reducing the overall time required for data transfer.

  • Page 18: Fault Tolerance

    Fault tolerance Drive failure, although rare, is potentially catastrophic. For example, using simple striping as shown Figure 3, failure of any hard drive leads to failure of all logical drives in the same array, and hence to data loss. To protect against data loss from hard drive failure, storage servers should be configured with fault tolerance.

  • Page 19: Partitions

    It is important to note that a LUN may span all physical drives within a storage controller subsystem, but cannot span multiple storage controller subsystems. gl0045 Figure 4 Two arrays (A1, A2) and five logical drives (L1 through L5) spread over five physical drives NOTE: This type of configuration may not apply to all storage servers and serves only as an example.

  • Page 20: File System Elements

    is important. The same performance characteristics on numbers of reads and writes apply when using fault-tolerant configurations, as is the case with controller-based RAID. These volumes can also be assigned drive letters or be mounted as mount points off existing drive letters. The administrator should carefully consider how the volumes will be carved up and what groups or applications will be using them.

  • Page 21: Using Storage Elements

    Using storage elements The last step in creating the element is determining its drive letter or mount point and formatting the element. Each element created can exist as a drive letter, assuming one is available, and/or as mount points on an existing folder or drive letter. Either method is supported. However, mount points cannot be used for shares that will be shared using Microsoft Services for Unix.

  • Page 22: Management Agents

    For additional information, refer to the Management CD in the HP ProLiant Essentials Foundation Pack or the HP SIM website (http://www.hp.com/go/hpsim). Management Agents Management Agents provide the information to enable fault, performance, and configuration management. The agents allow easy manageability of the server through HP SIM software, and thirdparty SNMP management platforms.

  • Page 23: File Server Management

    2 File server management This chapter begins by identifying file services in Windows Storage Server 2003 R2. The remainder of the chapter describes the many tasks and utilities that play a role in file server management. File services features in Windows Storage Server 2003 R2 Storage Manager for SANs The Storage Manager for SANs (also called Simple SAN) snap-in enables you to create and manage the LUNs that are used to allocate space on storage arrays.

  • Page 24: Windows Sharepoint Services

    administrators can place quotas on volumes, actively screen files and folders, and generate comprehensive storage reports. By using File Server Resource Manager, you can perform the following tasks: • Create quotas to limit the space allowed for a volume or folder and to generate notifications when the quota limits are approached and exceeded.

  • Page 25: Configurable And Pre-Configured Storage

    Configurable and pre-configured storage Certain storage servers ship with storage configured only for the operating system. The administrator must configure data storage for the storage server. Other storage servers ship with pre-configured storage for data. Depending on the type of storage server purchased, additional storage configuration is required.

  • Page 26: Array Configuration Utility

    NOTE: The ACU is used to configure and manage array-based storage. Software RAID-based storage servers use Microsoft Disk Manager to manage storage. You need administrator or root privileges to run the ACU. Array Configuration Utility The HP ACU supports the Smart Array controllers and hard drives installed on the storage server. To open the ACU from the storage server desktop: NOTE: If this is the first time that the ACU is being run, you will be prompted to select the Execution Mode for...

  • Page 27: Disk Management Utility

    Disk Management utility The Disk Management tool is a system utility for managing hard disks and the volumes, or partitions, that they contain. Disk Management is used to initialize disks, create volumes, format volumes with the FAT, FAT32, or NTFS file systems, and create fault-tolerant disk systems. Most disk-related tasks can be performed in Disk Management without restarting the system or interrupting users.

  • Page 28: Disk Quotas

    Defragmentation for a volume can be scheduled to occur automatically at convenient times. Defragmentation can also be done once, or on a recurring basis. NOTE: Scheduling defragmentation to run no later than a specific time prevents the defragmentation process from running later than that time.

  • Page 29: Adding Storage

    NOTE: When enabling disk quotas on a volume, any users with write access to the volume who have not exceeded their quota limit can store data on the volume. The first time a user writes data to a quota-enabled volume, default values for disk space limit and warning level are automatically assigned by the quota system.

  • Page 31: Volume Shadow Copies

    Volume shadow copies NOTE: Select storage servers can be deployed in a clustered as well as a non-clustered configuration. This chapter discusses using shadow copies in a non-clustered environment. The Volume Shadow Copy Service provides an infrastructure for creating point-in-time snapshots (shadow copies) of volumes.

  • Page 32: Allocating Disk Space

    NOTE: Shadow copies should not be used to provide access to previous versions of application or e-mail databases. Shadow copies are designed for volumes that store user data such as home directories and My Documents folders that are redirected by using Group Policy or other shared folders in which users store data.

  • Page 33: Identifying The Storage Area

    CAUTION: To change the storage volume, shadow copies must be deleted. The existing file change history that is kept on the original storage volume is lost. To avoid this problem, verify that the storage volume that is initially selected is large enough. Identifying the storage area To store the shadow copies of another volume on the same file server, a volume can be dedicated on separate disks.

  • Page 34: Mounted Drives

    NOTE: To check the cluster size of a volume, use the fsutil fsinfo ntfsinfo command. To change the cluster size on a volume that contains data, back up the data on the volume, reformat it using the new cluster size, and then restore the data. Mounted drives A mounted drive is a local volume attached to an empty folder (called a mount point) on an NTFS volume.

  • Page 35: The Shadow Copy Cache File

    Figure 5 System administrator view of Shadow Copies for Shared Folders The shadow copy cache file The default shadow copy settings allocate 10 percent of the source volume being copied (with a minimum of 350 MB), and store the shadow copies on the same volume as the original volume. (See Figure 6).

  • Page 36: Enabling And Creating Shadow Copies

    cache file cache file cache file Figure 7 Shadow copies stored on a separate volume The main advantage to storing shadow copies on a separate volume is ease of management and performance. Shadow copies on a source volume must be continually monitored and can consume space designated for file sharing.

  • Page 37: Viewing A List Of Shadow Copies

    NOTE: After the first shadow copy is created, it cannot be relocated. Relocate the cache file by altering the cache file location under Properties prior to enabling shadow copy. See “Viewing shadow copy properties” on page 37. Viewing a list of shadow copies To view a list of shadow copies on a volume: Access Disk Management.

  • Page 38: Redirecting Shadow Copies To An Alternate Volume

    CAUTION: Use caution when reducing the size limit for all shadow copies. When the size is set to less than the total size currently used for all shadow copies, enough shadow copies are deleted to reduce the total size to the new limit.

  • Page 39: Managing Shadow Copies From The Storage Server Desktop

    Managing shadow copies from the storage server desktop To access shadow copies from the storage server desktop: The storage server desktop can be accessed by using Remote Desktop to manage shadow copies. On the storage server desktop, double-click My Computer. Right-click the volume name, and select Properties.

  • Page 40: Smb Shadow Copies

    NOTE: Shadow Copies for Shared Folders clients are not available for HTTP, FTP, AppleTalk, or NetWare shares. Consequently, users of these protocols cannot use Shadow Copies for Shared Folders to independently retrieve previous versions of their files. However, administrators can take advantage of Shadow Copies for Shared Folders to restore files for these users.

  • Page 41: Nfs Shadow Copies

    Figure 9 Client GUI When users view a network folder hosted on the storage server for which shadow copies are enabled, old versions (prior to the snapshot) of a file or directory are available. Viewing the properties of the file or folder presents users with the folder or file history—a list of read-only, point-in-time copies of the file or folder contents that users can then open and explore like any other file or folder.

  • Page 42: Recovery Of Files Or Folders

    Access to NFS shadow copy pseudo-subdirectories is governed by normal access-control mechanisms using the permissions stored in the file system. Users can access only those shadow copies to which they have read access at the time the shadow copy is taken. To prevent users from modifying shadow copies, all pseudo-subdirectories are marked read-only, regardless of the user's ownership or access rights, or the permissions set on the original files.

  • Page 43: Recovering An Overwritten Or Corrupted File

    Figure 10 Recovering a deleted file or folder Recovering an overwritten or corrupted file Recovering an overwritten or corrupted file is easier than recovering a deleted file because the file itself can be right-clicked instead of the folder. To recover an overwritten or corrupted file: Right-click the overwritten or corrupted file, and then click Properties.

  • Page 44: Backup And Shadow Copies

    Backup and shadow copies Shadow copies are only available on the network via the client application, and only at a file or folder level as opposed to the entire volume. Hence, the standard backup associated with a volume backup will not work to back up the previous versions of the file system. To answer this particular issue, shadow copies are available for backup in two situations.

  • Page 45: Folder And Share Management

    Folder and share management The HP ProLiant Storage Server supports several file-sharing protocols, including DFS, NFS, FTP, HTTP, and Microsoft SMB. This section discusses overview information as well as procedures for the setup and management of the file shares for the supported protocols.

  • Page 52: Defining Access Control Lists

    The content of shares should be carefully chosen to avoid two common pitfalls: either having too many shares of a very specific nature, or of having very few shares of a generic nature. For example, shares for general use are easier to set up in the beginning, but can cause problems later. Frequently, a better approach is to create separate shares with a specific purpose or group of users in mind.

  • Page 53: Managing Shares

    • Standard shares are shares that do not end in a $ character. Standard shares are listed whenever a CIFS client browses for available shares on a CIFS server. The storage server supports both administrative and standard CIFS shares. To create an administrative share, end the share name with the $ character when setting up the share.

    • Client for NFS Normally, a Windows-based computer cannot access files on a UNIX computer. A computer running Windows Server 2003 R2 and Client for NFS, however, can access files stored on a UNIX-based NFS server. The Client for NFS feature of the Microsoft Services for NFS component is not preinstalled on the storage server although information about this feature appears in the online help.

  • Page 66: Authentication Table

    UNIX computers follow advisory locking for all lock requests. This means that the operating system does not enforce lock semantics on a file, and applications that check for the existence of locks can use these locks effectively. However, Server for NFS implements mandatory locks even for those locking requests that are received through NFS.
  • Page 67 To install the Authentication software on the domain controllers: From the SFU 3.5 files, locate the directory named SFU35SEL_EN.

Cluster components (virtual servers, file shares) are created, organized in groups, and placed within the folders using Cluster Administrator exclusively. Hierarchy of cluster resource components Figure 26 depicts the cluster resource hierarchy as follows:...

  • Page 94: Storage Planning

    • Storage planning • Network planning • Protocol planning Storage planning For clustering, a basic disk must be designated for the cluster and configured as the Quorum disk. Additional basic disks are presented to each cluster node for data storage as physical disk resources. The physical disk resources are required for the basic disks to successfully work in a cluster environment, protecting it from simultaneous access from each node.

  • Page 95: Protocol Planning

    Virtual names and addresses are the only identification used by clients on the network. Because the names and addresses are virtual, their ownership can transition from one node to the other during a failover, preserving access to the resources in the cluster group. A cluster uses at least two network connections on each node: •...

  • Page 96: Preparing For Cluster Installation

    NOTE: AppleTalk is not supported on clustered disk resources. AppleTalk requires local memory for volume indexing. On failover events, the memory map is lost and data corruption can occur. Preparing for cluster installation This section provides the steps necessary to cluster HP ProLiant Storage Servers. Before beginning installation Confirm that the following specifications have been met before proceeding: The procedures in the HP ProLiant Storage Server SAN Connection and Management white paper...

    • A domain user account for Cluster service (all nodes must be members of the same domain) • Each node should have at least two network adapters—one for connection to the public network and the other for the node-to-node private cluster network. If only one network adapter is used for both connections, the configuration is unsupported.

Presented additional nodes Complete this process for all cluster nodes. At this point all cluster nodes should be Post-installation Presented To configure the Cluster service on the storage server, an account must have administrative permissions on each node.

  • Page 100: Verifying Domain Membership

    Verifying domain membership All nodes in the cluster must be members of the same domain and able to access a domain controller and a DNS Server. Setting up a cluster account The Cluster service requires a domain user account under which the Cluster service can run. This user account must be created before installing Cluster service, because setup requires a user name and password.

  • Page 101: Using Cluster Administrator

    Using Cluster Administrator Cluster Administrator shows information about the groups and resources on all of your clusters and specific information about the clusters themselves. A copy of Cluster Administrator is automatically installed on a cluster node when the Cluster service is installed. Using Cluster Administrator remotely For remote administration, copies of Cluster Administrator can be installed on other computers on your network.

  • Page 102: Geographically Dispersed Clusters

    Geographically dispersed clusters Cluster nodes can be geographically dispersed to provide an additional layer of fault tolerance. Geographically dispersed clusters are also referred to as stretched clusters. The following rules must be followed with geographically dispersed clusters: • A network connection with latency of 500 milliseconds or less ensures that cluster consistency can be maintained.

  • Page 103: Load Balancing

    Load balancing The creation of separate cluster groups for each virtual server provides more flexibility in balancing the processing load on the cluster between the two nodes. Each cluster group can be assigned to a cluster node with the preferred owner parameter. For example, if there are two cluster groups, the cluster could be set up to have the first cluster group owned by Node A and the second cluster group owned by Node B.

  • Page 107: Print Services In A Cluster

    Print services in a cluster The Windows Server 2003 Cluster service implementation increases availability of critical print servers. A print spooler service on a clustered print server may be hosted on any of the nodes in the cluster. As with all cluster resources, clients should access the print server by its virtual network name or virtual IP address.

  • Page 108: Advanced Cluster Administration Procedures

    Advanced cluster administration procedures Failing over and failing back As previously mentioned, when a node goes offline, all resources dependent on that node are automatically failed over to another node. Processing continues, but in a reduced manner, because all operations must be processed on the remaining node(s). In clusters containing more than two nodes, additional fail over rules can be applied.

  • Page 109: Powering Down The Cluster

    Shutting down a cluster node causes all cluster resources served by that node to fail over to the other node(s). This causes any currently executing client read and write operations to fail until the cluster failover process completes. The other node(s) are placed under a heavier load by the extra work until the second node is powered up and rejoins the cluster.
