Select Kubernetes and OpenShift Bare Metal Worker Node Deprecations

1 min read

Worker node flavors with Coffee Lake and Cascade Lake processors and NVIDIA Tesla P100 GPUs are now available.

IBM Cloud Kubernetes Service and Red Hat OpenShift on IBM Cloud released a new fleet of monthly bare metal flavors for worker nodes in October 2020. These new flavors feature newer processors than our current flavors and provide options for a variety of use cases, with more cores, more memory, and more capable GPUs than were previously available.

These new flavors run Ubuntu 18 and include single and dual processor options ranging from 4 to 32 cores. The 4-core single processor flavors feature Coffee Lake processors, while the dual processor flavors feature Cascade Lake processors and are available in 20-core and 32-core varieties. Memory ranges from 32 to 768 GB, and some clusters include additional local storage for storing data on software-defined storage with Portworx. Kubernetes clusters can also leverage a GPU flavor that includes two NVIDIA Tesla P100 GPU cards.

Removal of previous bare metal and all Ubuntu 16 flavors

With the introduction of these new bare metal flavors, the previous bare metal flavors for IBM Cloud Kubernetes Service and Red Hat OpenShift on IBM Cloud are no longer available for ordering, effective immediately. The CPUs supporting the previous flavors entered End Of Life on December 31, 2020, and are no longer supported or purchasable through IBM Cloud Classic Infrastructure (announced August 2020). 

The list of affected previous flavors is as follows:

  • mb1c.4x32
  • mb2c.4x32
  • ms2c.4x32.1.9tb.ssd
  • mb1c.16x64
  • ms2c.16x64.1.9tb.ssd
  • ms2c.28x256.3.8tb.ssd
  • ms2c.28x512.4x3.8tb.ssd
  • mr1c.28x512
  • md1c.16x64.4x4tb
  • md1c.28x512.4x4tb
  • mg1c.16x128
  • mg1c.28x256
  • mb3c.4x32
  • mb3c.16x64
  • ms3c.4x32.1.9tb.ssd
  • ms3c.16x64.1.9tb.ssd
  • ms3c.28x256.3.8tb.ssd
  • ms3c.28x512.4x3.8tb.ssd
  • mr3c.28x512
  • md3c.16x64.4x4tb
  • md3c.28x512.4x4tb
  • mg3c.16x128
  • mg3c.28x256

Customer actions

This change will only affect users that need to increase the size of an existing worker pool that uses a flavor from the list above. Actions such as reboot, reload, and delete will continue to function. If the user needs to scale up, they will need to create a new worker pool within their cluster using the newer 4 series BM flavors recently released.
