Available Storage Classes

This page describes the different storage classes which are available on APPUiO Cloud zones.

The available storage classes differ depending on the cloud provider hosting the APPUiO Cloud zone.

cloudscale.ch

On cloudscale.ch we provide RWO storage using the csi-cloudscale CSI driver. Additionally, we provide RWX storage on CephFS managed via APPUiO Managed Storage Cluster.

The following storage classes are available on cloudscale.ch:

Storage Class Access Modes Description

ssd

RWO

This storage class provides cloudscale.ch ssd volumes.

If you don’t require RWX storage, we recommend using the ssd storage class.

ssd-encrypted

RWO

This storage class provides encrypted cloudscale.ch ssd volumes.

See the Setup Encrypted Volumes guide.

bulk

RWO

This storage class provides cloudscale.ch bulk volumes.

You may want to consider using the bulk storage class, if you’re working with very large amounts of data but read/write performance isn’t critical.

bulk-encrypted

RWO

This storage class provides encrypted cloudscale.ch bulk volumes.

See the Setup Encrypted Volumes guide.

cephfs-fspool-cluster

RWX

This storage class provides CephFS volumes.

Use this storage class if your application requires RWX storage.

Performance

We show representative performance numbers (IOPS and bandwidth) for each storage class below. Please note that we show the best case for write performance here.

Please see the APPUiO Managed Storage Cluster product documentation for an explanation of the benchmarking methodology and a more detailed breakdown of performance numbers.
