Overview

RAIC Volumes is a persistent block storage service that lets you create, attach, and manage storage volumes for your compute resources. Volumes provide high-performance, durable storage that persists independently of your compute resources, making them ideal for datasets, model checkpoints, training artifacts, and other data that needs to survive across cluster lifecycles.

Until now, RAIC offered Object Storage as the primary storage option. Volumes complement Object Storage by providing block-level access with mount path support, giving you the flexibility to choose the storage type that best fits your workload.

Key Benefits​

  • Persistent storage that survives cluster restarts.
  • Flexible sizing from 1 GiB up to 100 TB per location.
  • Location-aware provisioning to keep data close to your compute.
  • Simple mount path mapping when attaching to Supercomputer clusters.
  • Quota management with the ability to request additional capacity as needed.
note

Volumes are currently supported on Supercomputer clusters only. Support for additional compute resource types, including Kubernetes clusters and Virtual Machines, will be introduced in future releases.

Key Concepts​

  1. Volume

A Volume is a block storage resource that you create at a specific location with a defined size. Once created, a volume can be attached to a cluster by mapping it to a mount path. Volumes persist independently of compute resources. Your data remains intact even when clusters are deleted.

  1. Location

Each volume is provisioned at a specific data centre location. When creating a volume, you select the location where the volume will reside. For optimal performance, RAIC lets you attach volumes in the same location as the cluster.

  1. Quota

Every location has a default storage quota of 100 TB. This quota represents the maximum total storage capacity you can provision across all volumes within a single location. If your workloads require additional capacity beyond the default quota, you can submit a quota increase request directly from the console.

  • Go to Settings > Quotas
  • Choose Volumes from resource type and request for additional size against a location
  1. Mount Path

A mount path is the file system directory where the volume becomes accessible on the cluster. When attaching a volume to a cluster, you specify the mount path (e.g., /mnt/data or /workspace/models) to determine where the volume's contents will be available to your applications and training jobs.
