Software requirements

GPFS™ planning includes understanding the latest software requirements.

  • GPFS is supported on AIX®, Linux, and Windows.
  • For existing GPFS 3.5 clusters, OpenSSL is required for remote cluster access.
  • Kernel development files and compiler utilities are required to build the GPFS portability layer on Linux nodes. The required RPMs or packages for each supported Linux distribution are:
    SLES Linux RPMs
    • kernel-default-devel
    • cpp
    • gcc
    • gcc-c++
    • binutils
    RedHat Linux RPMs
    • kernel-devel
    • cpp
    • gcc
    • gcc-c++
    • binutils
    Debian and Ubuntu Linux packages
    • linux-headers
    • cpp
    • gcc
    • g++
    • binutils
  • To use active file management (AFM), the following is required:
    • nfs-utils
  • To use CNFS, the following are required:
    • ethtool
    • nfs-utils
    • rpcbind
    • psmisc
  • To use the mmchconfig numaMemoryInterleave parameter, the following is required:
    • numactl
  • For the IBM Spectrum Scale™ monitoring service on AIX and Linux, the following is required:
    • python 2.6 or later
    Note: python 2.7.5 or later is recommended on AIX. This package is a part of AIX Toolbox for Linux Applications.
