    HPSS. HPSS is the result of a collaborative effort by leading US Government supercomputer laboratories and industry to address very real, urgent high-end storage requirements. HPSS is offered commercially by IBM. HPSS provides scalable parallel storage systems for highly parallel computers as well as traditional supercomputers and workstation clusters.

  • Page 37: Hpss Components

    2.3. HPSS Components The components of HPSS include files, filesets, junctions, virtual volumes, physical volumes, storage segments, metadata, servers, infrastructure, user interfaces, a management interface, and policies. Media and file metadata are represented by data structures that describe the attributes and characteristics of storage system components such as files, filesets, junctions, storage segments, and volumes.

  • Page 39 recorded on these tapes. HPSS supports grouping files on tape volumes only. Families can only be specified by associating the family with a fileset. All files created in the fileset belong to the family. When one of these files is migrated from disk to tape, it is recorded on a tape with other files in the same family.
  • Page 40: Hpss Servers

    Class of Service (COS). Each bitfile has an attribute called Class Of Service. The COS • defines a set of parameters associated with operational and performance characteristics of a bitfile. The COS results in the bitfile being stored in a storage hierarchy suitable for its anticipated and actual size and usage characteristics.
  • Page 41 consisting of directories, files, and links. These name space objects may exist within filesets that are connected via junctions. Second, the Core Server provides the abstraction of logical bitfiles to its clients. A bitfile is identified by a Core Server generated name called a bitfile ID. Clients may reference portions of a bitfile by specifying the bitfile ID and a starting address and length.
  • Page 42 The purpose of tape file migration is to make an additional copy (or multiple additional copies) of a file, in a tape storage class, to a lower level in the hierarchy. It is also possible to move files downwards instead of copying them. In this case there is no duplicate copy maintained.
  • Page 43 Physical Volume Repository (PVR) • system may contain multiple PVRs, each cartridge is managed by only one. PVRs provide APIs for clients to request cartridge mounts and dismounts and query the status of cartridges. For convenience, PVRs are often configured in one-to-one correspondence to tape libraries. For information on the types of tape libraries supported by HPSS PVRs, see Section 3.4.2: Robotically Mounted Tape on page 62.
  • Page 44: Hpss Storage Subsystems

    2.3.3. HPSS Storage Subsystems The goal of storage subsystems (or just “subsystems”) is to increase the scalability of HPSS by allowing multiple Core Servers to be used within a single HPSS system. Every HPSS system is partitioned into one or more subsystems. Each subsystem contains a single Core Server. If migration and purge are needed, then the subsystem should contain a single Migration/Purge Server.
  • Page 45 HPSS Core Server performs most of the HPSS metadata changes using the transaction management tools provided by DB2. For the most part, these metadata transactions are managed entirely within the Core Server. Other servers such as MPS and PVL modify their metadata transactionally, and those transactions are entirely contained within those servers.

  • Page 51: Chapter 3. Hpss Planning

    3.1. Overview This chapter provides HPSS planning guidelines and considerations to help the administrator effectively plan, and make key decisions about, an HPSS system. The planning process for HPSS must be done carefully to ensure that the resulting system satisfies the site’s requirements and operates in an efficient manner. We recommend that the administrator read this entire chapter before planning the system.
  • Page 52: Hpss Configuration Planning

    Figure 4. HPSS Generic Configuration 3.1.2. HPSS Configuration Planning Before beginning the planning process, there is an important issue to consider. HPSS was designed to optimize the transfer of large files at the expense of some small file transfer performance. If at all possible, try to reduce the number of small files that are introduced into your HPSS system.
  • Page 53 aggregate the individual files into large individual files before moving them into the HPSS name space. The following planning steps must be carefully considered for the HPSS infrastructure configuration and the HPSS configuration phases: 1.

Requirements and Intended Uses for HPSS This section provides some guidance for the administrator to identify the site’s requirements and expectations of HPSS. Issues such as the amount of storage needed, access speed and data transfer speed, typical usage, security, expected growth, data backup, and conversion from an old system must be factored into the planning of a new HPSS system.
  • Page 57: Duplicate File Policy

    3.2.5. Duplicate File Policy The policy on duplicating user data files impacts the amount of data stored and the amount of data moved. If all user files are duplicated, the system will require twice as much tape storage. If users perform their own duplication of files, the system may consume a smaller amount of storage space.

    Starting with HPSS 6.2 there are many enhancements to the storage system to take advantage of Storage Area Networks. Though separated in Figure 4, in reality there is usually only one SAN at an installation and all the resources are attached to it. Besides the HPSS Movers being connected to SAN, the end-user clients are often SAN attached as well.

The tables and indexes are separated into separate logical volumes/partitions to ease future expansion of the database and to maximize performance of database operations. For Linux, access to a /dev/hdxy partition is through the Linux buffered I/O system. While this is an appropriate access method for a filesystem that supports journaled logging, for DB2 and Mover accesses, non-buffered IO is required.

  • Page 76 Definitions for the DB2 tables are as follows: Bitfile Disk Allocation Maps. (BFDISKALLOCREC) For each bitfile stored on disk, one or more rows will be created in the Disk Allocation Maps table. The number of rows is determined by the storage segment size in the Storage Class in which the files are stored and the average file size stored in that Storage Class.

    bytes. Disk Storage Segments. (STORAGESEGDISK) Expect the size of the disk storage segment metadata table to be quite volatile. As files are added to HPSS, disk storage segments will be created, and as files are migrated to tape and purged from disk, they will be deleted. A rough estimate of the number of disk storage segments can be obtained by estimating the number of files that will be resident on disk in the subsystem for each Storage Class, then multiplying by the Average Number of Segments parameter of the Storage Class.

    created will require approximately 10MB of disk space in a filesystem that should be used only for database home directories and other DB2 home directories (such as the DB2 Administration Server and Fenced User). This filesystem should be protected by RAID since DB2 may require information in the database home directory to properly recover a database.

    The amount of memory for nodes running HPSS Movers, and no DB2 servers, is dependent on the number and types of devices configured on the Mover node, the expected usages of those devices, and the configuration of the Movers memory than Movers supporting tape devices because disk devices are likely to have more outstanding requests.

Core Server The Core Server is responsible for managing the HPSS name space (files, directories, links, etc.), bitfiles, and storage (physical volumes, virtual volumes, etc.) for a single subsystem. Each of these areas of responsibility are outlined in greater detail below. Core Server at large The Core Server uses POSIX threads to service concurrent requests.
  • Page 82: Figure 6. The Relationship Of Various Server Data Structures

    Figure 6. The Relationship of Various Server Data Structures Disk Storage Allocation Each Core Server manages disk storage units for HPSS. It maps each disk storage unit onto an HPSS disk Physical Volume (PV) and records configuration data for the PV. Groups of one or more PVs (disk stripe groups) are managed by the server as disk Virtual Volumes (VVs).
  • Page 83: Migration/Purge Server

    The Core Server is designed to scale up its ability to manage tapes as the number of tapes increases. As long as sufficient memory and CPU capacity exist, threads can be added to the server to increase its throughput. Additional subsystems can also be added to a system, increasing concurrency even further.

Also, unpredictable purge behavior may be observed if the purge record ordering is changed with existing purge records in the system until these existing records are cleared. A purge run ends when either the supply of purge records is exhausted or the purge target is reached.
  • Page 85 Sites can choose to configure zero (0) or more Gatekeepers per HPSS system. Gatekeepers are associated with storage subsystems. Each storage subsystem can have zero or one Gatekeeper associated with it and each Gatekeeper can support one or more storage subsystems. Gatekeepers are associated with storage subsystems using the Storage Subsystem Configuration screen (see Section 4.2: Storage Subsystems of the HPSS Management Guide).

It is important that the Site Interfaces return a status in a timely fashion. Create, open, and stage requests from MPS are timing sensitive, thus the Site Interfaces won't be permitted to delay or deny these requests, however the Site Interfaces may choose to be involved in keeping statistics on these requests by monitoring requests from Authorized Callers.

At least one PVR should be created for every robot managed by HPSS. If multiple 3494 robots are managed, care must be taken to ensure that the PVRs are configured to communicate with the correct /dev/lmcp devices.

    For Solaris, the method used to enable variable block sizes for a tape device is dependent on the type of driver used. Supported devices include Solaris SCSI Tape Driver and IBM SCSI Tape Driver. For the IBM SCSI Tape Driver, set the block_size parameter in the /opt/IBMtape/IBMtape.conf configuration file to 0 and perform a reboot with the reconfiguration option.

    Driver has a built-in configuration table for all HPSS supported tape drives. This configuration provides variable block size for most HPSS supported drives. In order to override the built-in configuration, device information can be supplied in the /dev/kernel/st.conf as global properties that apply to each node.

It shares responsibility with each HPSS server for ensuring that only one copy of the server runs at a given time. It helps the SSM determine whether servers are still running, and it allows the SSM to send signals to servers.
