Hardware requirements

Before you install IBM® Cloud Pak for Data, review the hardware requirements for the control plane, the shared cluster components, and the services that you plan to install.

Cloud Pak for Data platform hardware requirements

You must install Cloud Pak for Data on a Red Hat® OpenShift® Container Platform cluster. For information about the supported versions of Red Hat OpenShift Container Platform, see Software requirements.

It is strongly recommended that you deploy Cloud Pak for Data on a highly available cluster.

The following requirements are the minimum recommendations for a small, stable deployment of Cloud Pak for Data. Use the minimum recommended configuration as a starting point for your cluster configuration. If you use fewer resources, you are likely to encounter stability problems.

The following configuration has been tested and validated by IBM. However, Red Hat OpenShift Container Platform supports other configurations. If the configuration in the following table does not work in your environment, you can adapt the configuration based on the guidance in the Red Hat OpenShift documentation. (Links to the relevant Red Hat OpenShift documentation are available in Software requirements.) In general, Cloud Pak for Data is primarily concerned with the resources that are available on your worker nodes.

Important:
Work with your IBM Sales representative to size your cluster. The size of your cluster depends on:
  • The shared components that you need to install
  • The services that you plan to install

    The sizing requirements for services are available in Service hardware requirements. If you install only a few services with small vCPU and memory requirements, you might not need additional resources. However, if you plan to install multiple services or services with large footprints, add the appropriate amount of vCPU and memory to the minimum recommendations below.

  • The types of workloads that you plan to run

    For example, if you plan to run complex analytics workloads in addition to other resource-intensive workloads, such as ETL jobs, you can expect reduced concurrency levels if you don't add additional computing power to your cluster.

    Because workloads vary based on a number of factors, use measurements from running real workloads with realistic data to size your cluster.

Node role Hardware Number of servers Minimum available vCPU Minimum memory Minimum storage
Master + infra
  • x86-64
  • s390x (z14 or later)
  • ppc64le
 3 master (for high availability) and 3 infrastructure on the same 3 nodes 8 vCPU per node 32 GB RAM per node No additional storage is needed. For sizing guidance, refer to the Red Hat OpenShift Container Platform documentation.
Worker/compute
  • x86-64
  • s390x (z14 or later)
  • ppc64le
 3+ worker/compute nodes 16 vCPU per node
  • 64 GB RAM per node (minimum)
  • 128 GB RAM per node (recommended)
 300 GB of storage space per node for storing container images locally. See Cloud Pak for Data platform storage requirements for details.
Load balancer
  • x86-64
  • s390x (z14 or later)
  • ppc64le
 2 load balancer nodes 4 vCPU per node 4 GB RAM per node

Add another 4 GB of RAM for access restrictions and security control.

 Add 100 GB of root storage for access restrictions and security control.
Restriction:
Power® hardware
Power is supported on the following versions of Red Hat OpenShift Container Platform:
  • Version 4.8
  • Version 4.10

The platform supports Power 9 and Power 10, but does not take advantage of Power 10 optimizations.

Not all services support Power. For details, see Service hardware requirements.

On Power hardware the maximum supported configuration for each worker node is:

  • 160 vCPU
  • 512 GB RAM
s390x hardware
s390x is supported only on Red Hat OpenShift Container Platform Version 4.8.

Not all services support s390x. For details, see Service hardware requirements.

Load balancer
A load balancer is required when using three master nodes. The load balancer distributes the traffic load of the master and proxy nodes, securely isolates the master and compute node IP addresses, and facilitates external communication, including accessing the management console and API or making other requests to the master and proxy nodes.

Cluster node settings

The time on all of the nodes must be synchronized within 500 ms.

Some services require additional node settings to run correctly. For information about the node settings and the services that require them, see Changing required node settings. You must change the node settings before you install Cloud Pak for Data.

Disk requirements

To prepare your storage disks, ensure that you have good I/O performance, and prepare the disks for encryption.

I/O performance
When I/O performance is not sufficient, services can experience poor performance or cluster instability, such as functional failures with timeouts. This is especially true when you are running a heavy workload.

The I/O performance requirements for Cloud Pak for Data are based extensive testing in various cloud environments. The tests validate the I/O performance in these environments. The requirements are based on the performance of writing data to representative storage classes using the following block size and thread count combinations:

  • To evaluate disk latency, the I/O tests use a small block (4 KB) with 8 threads
  • To evaluate disk throughput, the I/O tests us a large block (1 GB) with 2 threads

To evaluate the storage performance on the cluster where you plan to install Cloud Pak for Data, run the Cloud Pak for Data storage performance validation playbook. Ensure that the results are comparable to the following recommended minimum values:

Disk latency (4 KB block with 8 threads)
For disk latency tests, 18 MB/s has been found to provide sufficient performance.
Disk throughput (1 GB block with 2 thread)
For disk throughput tests, 226 MB/s has been found to provide sufficient performance.

To ensure sufficient performance, both requirements should be satisfied.

Some storage types might have more stringent I/O requirements. For details, see Storage considerations.

Important: It is recommended that you run the validation playbook several times to account for variations in workloads, access patterns, and network traffic.

In addition, if your storage volumes are remote, network speed can be a key factor in your I/O performance. For good I/O performance, ensure that you have sufficient network speed, as described in Storage considerations.

Encryption with Linux® Unified Key Setup
To ensure that your data within Cloud Pak for Data is stored securely, you can encrypt your disks. If you use Linux Unified Key Setup-on-disk-format (LUKS), you must enable LUKS when you install Red Hat OpenShift Container Platform. For more information, see Encrypting disks during installation in the Red Hat OpenShift Container Platform documentation.

Shared cluster component requirements

Shared cluster components provide underlying functionality for the IBM Cloud Pak for Data control plane and services. For details, see Required components.

    Local storage in /var/lib/containers
    Adjust the amount of local storage per node based on the volume of data you are analyzing. Local storage should be approximately 2 times larger than the amount of data you expect the system to process concurrently.
    Persistent storage
    The raw size of shared storage depends on the storage class you use. For example, if you use portworx-shared-gp3, which has 3 replicas, multiply the storage by the number of replicas.

    On OpenShift 4.6, the recommended location is a partition in /var/lib. For details, see Understanding ephemeral storage.

    If you don't have sufficient space on the local disk, Spark jobs might run slowly and some of the executors might evict jobs. A minimum of 50 GB of temporary storage for each vCPU request is recommended.
