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
    • Red Hat 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 (on Ubuntu: nfs-common)
    • 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.
