Minimum Hardware and Software Requirements

Hardware Requirements
Operating System
Communication Protocol
Additional Software
Version 7.1

Hardware
POWER5® and newer systems computer (64-bit)

______________________________
Memory
The following minimum values for memory:

  • 12 GB.
  • 16 GB if you are using data deduplication.
  • At least 32 GB for heavily used servers. Using 32 GB or more of memory enhances performance of the Tivoli Storage Manager server database inventory.
  • If you plan to run multiple instances, each instance requires the memory listed for one server. Multiply the memory for one server by the number of instances planned for the system.
  • Node replication processing requires additional memory. Use a minimum of 32 GB of memory for node replication without data deduplication. Node replication with data deduplication requires a minimum of 64 GB of memory.
  • When you create the active log, you need at least 64 GB of memory to run replication. If replication and deduplication are both being used, create an active log of 128 GB in size.
___________________________
Disk space
The following minimum values for disk space:
  • 512 MB for the /var directory
  • 4 GB for the installation directory
  • 2 GB for the /tmp directory
  • 300 MB for the /usr directory
  • 2 GB in the home directory
Tip: Expect to use more space for problem determination.
  • 2 GB for the shared resources area

Significant additional 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. Allocate at least three times the 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. See Optimizing Performance for more information about the configuration of directories for the database. In addition, each active log and archive log should have its own container or LUN.

Ensure that you see the capacity planning section for more details about disk space.

Version 7.1

One of the following operating systems:
  • Red Hat Enterprise Linux 6
  • SUSE Linux Enterprise Server 11, Service Pack 2
Version 7.1
  • TCP/IP Version 4 or Version 6, which is standard with Linux
  • Shared memory protocol (with Tivoli Storage Manager Version 6.3 System p® client)
Version 7.1

Libraries
GNU C libraries, Version 2.3.3-98.38 or later that is installed on the Tivoli Storage Manager system.

Libaio.so.1 for Red Hat Enterprise Linux and SUSE Linux Enterprise Servers.

If you are running SUSE Linux Enterprise Server 11, download the XL C/C++ runtime package V12.1.0.1. See the following link for instructions: http://www.ibm.com/support/docview.wss?uid=swg24022673.

Disable SELinux:
To determine if SELinux is installed and in enforcing mode, perform one of the following tasks:

  • 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 reboot the machine.

Processing
Asynchronous I/O must be enabled.

Web browser
A web browser to retrieve an online installation package. The following browsers are supported:
  • Microsoft Internet Explorer 7.0 or later
  • Firefox 3.5 or later

Your browser must support the server code page. If your browser does not support the server code page, the windows might be unreadable. If your browser meets these requirements but does not correctly display a Tivoli Storage Manager web-based interface, consider using a different browser.

Other software
Korn Shell (ksh)
Version 6.3

Memory
Recommended

  • 12 GB.
  • 16 GB if you are using deduplication.
  • At least 32 GB for heavily used servers. Using 32 GB or more of memory enhances performance of the Tivoli Storage Manager server database inventory.
  • If you plan to run multiple instances, each instance requires the memory listed for one server. Multiply the memory for one server by the number of instances planned for the system.
___________________________
Disk space
The following minimum disk space:
  • 5 MB for the /var directory
  • 30 MB for the /opt directory if you create mount points
  • 2 GB for the /opt/tivoli/tsm directory
  • 390 MB for the /tmp directory
  • 300 MB for the /usr directory
  • 2 GB in the home directory
Tip: Expect to use more space for problem determination.

Significant additional 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. Allocate at least three times the active log space for the archive log (48 GB). Ensure that you have sufficient resources if you are using deduplication or expect a heavy client workload.

For optimal performance and to facilitate I/O, specify at least four separate directories or Logical Unit Numbers (LUNs) to be used by the database and logs. By making these specifications, I/O is balanced across multiple directories or mounts.

Ensure that you see the capacity planning section for more details about disk space.

Version 6.2

Linux on POWER IBM® system such as one of the systems listed in the following Linux for Power server solution Web site:http://www-03.ibm.com/systems/power/software/linux/about/index.html

Recommended and minimum memory requirements and minimum space requirements to run:
Recommended memory: 12 GB. 16 GB if you are using deduplication.

Also consider:
· Large production servers may require more than the recommended amount of memory.

Minimum memory: 4 GB for small production servers. A server is considered to be small if it has the following characteristics:

· It does not use storage pool deduplication.

· It supports only a small number of clients, or the nightly backup data transferred is 100 GB or less.

· It is used only as a library manager.

· On a machine having only 4 GB of RAM, only a single server is being run.

Additional information to consider:
· If the intention is to run with less than the recommended amount of memory, it is further suggested that this configuration be tested under those circumstances to determine that this will support the intended workload in this particular environment. Or if V6.1 servers are already implemented in these less then recommended memory environments, that would also provide a proof point that this may be suitable for these particular environments.

For more details about deduplication, search the keyword deduplication.


Disk Space:

  • 5 MB for the /var directory
  • 10 MB for the /opt directory if you create mount points
  • 4 GB for the /opt/tivoli/tsm directory if you create mount points
  • 390 MB for the /tmp directory
  • 300 MB for the /usr directory
  • 2 GB in the home directory

Significant additional 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. Allocate at least three times the active log space for the archive log (48 GB). Ensure that you have sufficient resources if you are using deduplication or expect a heavy client workload.

For optimal performance and to facilitate I/O, specify at least four separate directories or Logical Unit Numbers (LUNs) to be used by the database and logs. This allows I/O to be balanced across multiple directories or mounts.

Note: Raw logical volumes are not supported.
