Chapter 1 HPSS Basics
38 September 2002 HPSS Installation Guide
Release 4.5, Revision 2
The MPI-IO API can be ported to any platform that supports a compatible host MPI and the HPSS
Client API (DCE or Non-DCE version). See Section 2.5.6: MPI-IO API on page 60 for determining a
compatible host MPI.
The XFS HDM is supported on standard Intel Linux platforms as well as the OpenNAS network
appliance from Consensys Corp.
1.4.2 Server and Mover Platforms
HPSS currently requires at least one AIX or Solaris machine for the core server components. The
core server machine must include DCE and Encina as prerequisites (see Section 2.3: Prerequisite
Software Considerations on page 46) and must have sufficient processing power and memory to
handle the work load needed by HPSS.
HPSS is a distributed system. The main component that is replicated is the Mover, used for logical
network attachment of storage devices. The Mover is currently supported in two modes of
operation. In the first mode, the Mover is supported on AIX and Solaris platforms, which require
DCE and Encina services. In the second mode, a portion of the Mover runs on the AIX or Solaris
platform (again requiring DCE and Encina), but the portion of the Mover that manages HPSS
devices and transfers data to/from clients runs on platforms that do not require DCE or Encina
services. This second portion of the Mover that handles data transfers is supported on AIX, IRIX
and Solaris.
