Environments in Test

Software components

Component Level Comments
Spectrum Scale 5.0.4.1 x86_64
OS RHEL 7.5, RHEL 7.6, RHEL 7.7 worker nodes
Kubernetes 1.13, 1.14, 1.15, 1.16
Docker 18.03, 18.06
OpenShift 4.2

Example Hardware Configs

All examples below consider a non-production test environment:

Small virtual cluster testbed

This environment assumes a minimum number of nodes to perform goodpath testing. Because this assumes a virtual environment, understand the Spectrum Scale support statement for KVM / VMware clusters

Node Type # Cores RAM HD Spectrum Scale K8s
Master node 1x 2core 8GB 50GB do not install required
Worker node 2x 2core 16GB 50GB required required
GUI node 1x 2core 16GB 50GB required do not install
NSD node 2x 2core 8GB 50GB required not recommended

  • gpfs pagepool set to 2GB (mmchconfig pagepool=2G)

  • No other Spectrum Scale functions installed

  • Do not install Spectrum Scale on the Master node

  • Do not install Kubernetes on the GUI node

  • NSD nodes with shared disks (8x 10GB) for NSD and file system creation. Boost memory and cpu cores on NSD nodes if stacking K8s / Scale functionality

OpenShift VMware testbed

This environment assumes a minimum number of nodes to perform goodpath testing. Because this assumes a virtual environment, understand the Spectrum Scale support statement for KVM / VMware clusters

Node Type # Cores RAM HD Spectrum Scale K8s
Master node 3x 4core 16GB 120GB do not install required
Infrastructure node 3x 4core 16GB 120GB required required
Worker node 3x 2core 16GB 120GB required required
GUI node 1x 2core 16GB 50GB required do not install
NSD node 2x 2core 16GB 50GB required not recommended

  • pagepool set to 8GB on workers, 4GB on NSD and GUI

  • No other Spectrum Scale functions installed

  • Master nodes will run RHCOS. Spectrum Scale is not supported on RHCOS nodes. Do not install Spectrum Scale on the master nodes.

  • Do not add Spectrum Scale GUI node to Openshift cluster

  • NSD nodes with shared disks (8x 10GB) for NSD and file system creation. Boost memory on NSD nodes if stacking K8s / Scale functionality

OpenShift baremetal testbed

Node Type # Cores RAM HD Spectrum Scale K8s
Master node 3x 2core 64GB 120GB do not install required
Infrastructure node 3x 4core 64GB 120GB required required
Worker node 3x 2core 128GB 120GB required required
GUI node 1x 2core 32GB 50GB required do not install
NSD node 2x 2core 32GB 50GB required not recommended

  • pagepool set to 32GB on workers, 8GB on NSD and GUI

  • no other Spectrum Scale functions installed

  • Master nodes will run RHCOS. Spectrum Scale is not supported on RHCOS nodes. Do not install Spectrum Scale on the master nodes.

  • Do not add Spectrum Scale GUI node to Openshift cluster

  • NSD nodes with shared disks (8x 100GB) for NSD and file system creation. Boost memory and cpu cores on NSD nodes if stacking K8s / Scale functionality
