GPFS clusters can combine all supported node types, including Linux, IBM AIX, and home windows Server. Those nodes can all be connected to a not-unusual set of SAN storage or through a mixture of SAN and network-connected nodes. Nodes can all be in a single cluster, or statistics can be shared across multiple clusters. A cluster may be GPFS contained in the middle of a single record or unfold throughout geographical locations. To decide which cluster configuration is well for your application, start with the help of determining the following:

  • Application I/O overall performance and reliability requirements
  • The residences of the underlying storage hardware.
  • Administration, security, and possession considerations

Knowledge of those necessities enables you to determine which nodes require direct get entry to the disks and which nodes should get entry to the disks over a network connection through an NSD server.

There are 4 fundamental GPFS configurations:

  • All nodes attached to a commonplace set of LUNS
  • a few nodes are NSD customers
  • A cluster is unfolding across more than one websites
  • records are shared among clusters

GPFS Servers and GPFS customers

You may configure a GPFS cluster in which a few nodes have an instantaneous attachment to the disks, and others get entry to the disks through different GPFS nodes. This configuration is regularly used in huge clusters or to offer a price-effective, excessive-performance solution.

When a GPFS node is presenting gets the right of entry to a disk for some other GPFS node, it’s known as an NSD Server. The GPFS node accessing the information by an NSD server is known as a GPFS consumer.

Procedure for putting in GPFS on AIX nodes

These installation procedures are generalized for all degrees of GPFS. Ensure your replacement has the proper numeric fee for the change (m) and fasten (f) ranges, which is applicable. The amendment and attached degree are established upon the cutting-edge level of software assistance.

These steps to put in the GPFS software for the usage of the install command:

  1. Accepting the digital license agreement: The IBM Spectrum Scale software license settlement is distributed and viewable electronically. The digital license agreement must be prevalent before the software program setup can continue.
  1. Growing the GPFS directory
  2. Growing the GPFS set up desk of contents file
  3. Putting in the GPFS guy pages
  4. Putting in GPFS over a network
  5. Verifying the GPFS installation

There are 3 steps to putting in GPF on AIX nodes.

Before installing, study planning for GPFS and the IBM Spectrum Scale FAQ in the IBM information center.

Do not attempt to install GPFS if you no longer have the prerequisites indexed in hardware and software program requirements.

The installation procedure consists of the following:

  • Creating a document to ease the AIX installation method

The introduction of a document that incorporates all the nodes for your GPFS cluster before the installation of GPFS can be useful during the setup system. Using hostnames or IP addresses while building the record will assist you in using these records4 while creating your cluster through the command.

  • Verifying the level of prerequisite software program

Before installing GPFS, verify that your gadget has the precise software levels installed.

Those setup methods are generalized for all ranges of GPFS. Make sure you replace the right numeric price for the amendment (m) and fix (f) stages where relevant. The modification and connect stage are structured upon the current level of the software guide.

Installing and upgrading

You must perform numerous steps to establish and start your GPFS cluster. This topic gives the statistics you need for performing the steps.

• Putting in IBM Spectrum Scale on Linux nodes and deploying protocols

Use this fact to install IBM Spectrum Scale on Linux nodes and deploy protocols.

This describes how to prepare for the setup of the Transparent Cloud Tiering.

• Installing active record management

The subsequent subjects describe the way to install lively report control.

• Installing AFM-based disaster healing

The primary and the secondary are separate operational clusters separated from each other through LAN or WAN. AFM DR features are available in the superior version of the IBM Spectrum Scale. All primary and secondary cluster nodes should go for walks in the advanced version.

• Migration, coexistence, and compatibility

Emigrate to IBM Spectrum Scale 4.2.x; first, remember the model you are migrating from and then consider coexistence and compatibility troubles.

GPFS maintains some documents that incorporate configuration and record machine-associated statistics. Considering that these documents are critical for the proper functioning of GPFS and need to be preserved across releases, they are now not robotically removed when you uninstall GPFS.
