Chapter 1 HPSS Basics

1.1 Introduction

The High Performance Storage System (HPSS) is software that provides hierarchical storage

management and services for very large storage environments. HPSS may be of interest in

situations having present and future scalability requirements that are very demanding in terms of

total storage capacity, ﬁle sizes, data rates, number of objects stored, and numbers of users. HPSS

is part of an open, distributed environment based on OSF Distributed Computing Environment

(DCE) products that form the infrastructure of HPSS. HPSS is the result of a collaborative effort by

leading US Government supercomputer laboratories and industry to address very real, very urgent

high-end storage requirements. HPSS is offered commercially by IBM Worldwide Government

Industry, Houston, Texas.

HPSS provides scalable parallel storage systems for highly parallel computers aswell as traditional

supercomputers and workstation clusters. Concentrating on meeting the high end of storage

system and data management requirements, HPSS isscalable and designedto store up to petabytes

(10

15

) of data and to use network-connected storage devices to transfer data at rates up to multiple

gigabytes (10

9

) per second.

HPSS provides a large degree of control for the customer site to manage their hierarchical storage

system. Using conﬁguration information deﬁned by the site, HPSS organizes storage devices into

multiple storage hierarchies. Based on policy information deﬁned by the site and actual usage

information, data are then moved to the appropriate storage hierarchy and to appropriate levels in

the storage hierarchy.

1.2 HPSS Capabilities

A central technical goal of HPSS is to move large ﬁles between storage devices and parallel or

clustered computers at speeds many times faster than today’s commercial storage system software

products, and to do this in a way that is more reliable and manageable than is possible with current

systems. In order to accomplish this goal, HPSS is designed and implemented based on the

concepts described in the following subsections.

1.2.1 Network-centered Architecture

The focus of HPSS is the network, not a single server processor as in conventional storage systems.

HPSS provides servers and movers that can be distributed across a high performance network to

Chapter 1 HPSS Basics

20 September 2002 HPSS Installation Guide

Release 4.5, Revision 2

provide scalability and parallelism. The basis for this architecture is the IEEE Mass Storage System

Reference Model, Version 5.

1.2.2 High Data Transfer Rate

HPSS achieves high data transfer rates by eliminating overhead normally associated with data

transfer operations. In general, HPSS servers establish transfer sessions but are not involved in

actual transfer of data.

1.2.3 Parallel Operation Built In

The HPSS Application Program Interface (API) supports parallel or sequential access to storage

devices by clients executing parallel or sequential applications. HPSS also provides a Parallel File

Transfer Protocol. HPSS can even manage data transfers in a situation where the number of data

sources and destination are different. Parallel data transfer is vital in situations that demand fast

access to very large ﬁles.

1.2.4 A Design Based on Standard Components

HPSS runs on UNIX with no kernel modiﬁcations and is written in ANSI C and Java. It uses the

OSF Distributed Computing Environment (DCE) and Encina from Transarc Corporation as the

basis for its portable, distributed, transaction-based architecture. These components are offered on

many vendors’ platforms. Source code is available to vendors and users for porting HPSS to new

platforms. HPSS Movers and the Client API have been ported to non-DCE platforms. HPSS has

been implemented on the IBM AIX and Sun Solaris platforms. In addition, selected components

have been ported to other vendor platforms. The non-DCE Client API and Moverhave been ported

to SGI IRIX, while the Non-DCE Client API has also been ported to Linux. Parallel FTP client

software has been ported to a number of vendor platforms and is also supported on Linux. Refer

to Section 1.4: HPSS Hardware Platforms on page 37 and Section 2.3: Prerequisite Software

Considerations on page 46 for additional information.

1.2.5 Data Integrity Through Transaction Management

Transactional metadata management and Kerberos security enable a reliable design that protects

user data both from unauthorized use and from corruption or loss. A transaction is an atomic

grouping of metadata management functions that either take place together, or none of them take

place. Journaling makes it possible to back out any partially complete transactions if a failure

occurs. Transaction technology is common in relational data management systems but not in

storage systems. HPSS implements transactions through Transarc’s Encina product. Transaction

management is the key to maintaining reliability and security while scaling upward into a large

distributed storage environment.

1.2.6 Multiple Hierarchies and Classes of Services

Most other storage management systems support simple storage hierarchies consisting of one kind

of disk and one kind of tape. HPSS provides multiple hierarchies, which are particularly useful

when inserting new storage technologies over time. As new disks, tapes, or optical media are
