Detailed System Requirements


Abstract

IBM Storage Protect 8.1.23 for Linux on System z Server requirements and support.

Minimum Hardware and Software Requirements
This document describes the minimum hardware and software required to install and run the IBM Storage Protect 8.1.23 server on Linux on System z.
Hardware requirements
Type of hardware Hardware requirements
General An IBM zSeries, IBM System z9, IBM System z10, or IBM zEnterprise System (z114 and z196) 64-bit native logical partition (LPAR) or z/VM guest.
Disk space The following minimum values for disk space:
  • 7.5 GB for the installation directory
  • 2.5 GB for the /var directory
  • 4 GB for the /tmp directory
  • 128 MB in the home directory for the root user.
  • 2 GB for the shared resources area
If a problem arises that requires diagnosis, it is optimal to have additional temporary space available for uses such as a first failure data capture (FFDC) log or in which to collect trace logs.
Significant disk space is required for database and log files. The size of the database depends on the number of client files to be stored and the method by which the server manages them. The default active log space is 16 GB, the minimum that is needed for most workloads and configurations. When you create the active log, you need at least 64 GB to run replication. If replication and data deduplication are both being used, create an active log of 128 GB. Allocate at least three times the default active log space for the archive log (48 GB). Ensure that you have sufficient resources if you are using data deduplication or expect a heavy client workload.

For optimal performance and to facilitate I/O, specify at least two equally sized containers or Logical Unit Numbers (LUNs) for the database. In addition, each active log and archive log needs its own container or LUN.
Memory The following minimum values for memory:
  • 16 GB for standard server operations without data deduplication and node replication
  • 24 GB for data deduplication or node replication
  • 32 GB for node replication with data deduplication
For more specific memory requirements for larger databases and higher ingestion capability, see the IBM Storage Protect server memory tuning table.
For more specific memory requirements when you are using data deduplication, see the IBM Storage Protect Blueprint for your operating system.
Software requirements
Type of software Minimum software requirements
Operating System
The IBM Storage Protect server on Linux on System z (s390x 64-bit architecture) requires one of the following operating systems:
  • Red Hat Enterprise Linux 7.6 or later RHEL 7 levels
  • Red Hat Enterprise Linux 8.4 or later RHEL 8 levels
  • SUSE Linux Enterprise Server 12, SP4 or later SLES 12 levels
Restriction: The storage area network (SAN) discovery feature is not supported.
Libraries
GNU C libraries, Version 2.3.3-98.38 or later, which are installed on the IBM Storage Protect system.
For Red Hat Enterprise Linux Servers:
  • The libaio library.
  • The 64 bit libstdc++.so.6 library.
For SUSE Linux Enterprise Servers:
  • The libaio library.
  • The libstdc++.so.6 library at version 4.3 or later.  Both 32-bit and 64-bit packages are required.
  • The libxlc-1.2.0.0.151119a.s390x or later library.
Restriction: SELinux must be disabled for IBM Storage Protect installations and upgrades. To determine if SELinux is installed and in enforcing mode, take one of the following actions:
  • Check the /etc/sysconfig/selinux file.
  • Run the "sestatus" operating system command.
  • Check the /var/log/messages file for SELinux notices.
To disable SELinux, complete one of the following tasks:
  • Set permissive mode by issuing the "setenforce 0" command as a superuser.
  • Modify the /etc/sysconfig/selinux file and restart the machine.
Communication protocol
  • TCP/IP Version 4 or Version 6, which is standard with Linux
  • Shared memory protocol (with IBM Storage Protect Linux s390x client)
Processing Asynchronous I/O must be enabled. On Linux kernels at 2.6 or later, install the libaio library to enable asynchronous I/O.
Device drivers
The IBM Storage Protect passthru device driver is used for non-IBM devices.  It uses the SCSI passthru interface to communicate with tape devices and tape libraries. The Linux SCSI Generic (sg) device driver is required for tape drives and tape libraries. The IBM Storage Protect device driver package contains device driver tools and ACSLS daemons.

For the IBM 3590, 3592, or the Ultrium tape library or drives, the IBM device drivers are required. Install the most current device drivers. You can locate IBM driver packages at Fix Central.

Configure the device drivers before you use the IBM Storage Protect server with tape devices.
Other software
  • Korn Shell (ksh)
  • To authenticate IBM Storage Protect users with a Lightweight Directory Access Protocol (LDAP) server, you must use one of the following directory servers:
    • Microsoft Active Directory (Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019)
    • IBM Security Directory Server V6.3.1
    • IBM Security Directory Server V6.4
