Available Storage Classes
The NETWAYS Cloud offers various storage classes. These differ in their IOPS configuration (Input/Output Operations, the number of read and write operations per second).
The following overview lists the storage classes available in the NETWAYS Cloud. A distinction must be made between Base and Burst IOPS:
- Base IOPS describe the number of read/write operations generally available, even over longer periods.
- Burst IOPS describe the maximum number of read/write operations available only briefly for 60 seconds.
Local Storage
Storage available locally in VMs or on Kubernetes Nodes is always sourced from local NVMe SSDs on the underlying hypervisor.
The following information applies exclusively to block storage, which can be attached to VMs or Kubernetes Nodes in the form of volumes.
IOPS Overview per Storage Class
general-purpose-1
| max. IOPS | |
|---|---|
| Base | ~1000 |
| Burst | ~2000 |
general-purpose-2
| max. IOPS | |
|---|---|
| Base | ~2000 |
| Burst | ~4000 |
performance-optimized-1
| max. IOPS | |
|---|---|
| Base | ~2500 |
| Burst | ~5000 |
performance-optimized-2
| max. IOPS | |
|---|---|
| Base | ~5000 |
| Burst | ~10000 |
Using Storage Classes
In VMs
In the NETWAYS Cloud, volumes can be created via the OpenStack interface at console.nws.netways.de from the available storage classes.
In NETWAYS Managed Kubernetes®
In NETWAYS Managed Kubernetes®, the listed storage classes are pre-configured under their respective names and can be used directly in PersistentVolumes or PersistentVolumeClaims.
For more information about storage classes in NETWAYS Managed Kubernetes®, visit the Available Storage Classes in the Kubernetes Documentation.
Encryption of Storage Classes
All storage classes can also be used in an encrypted variant. For this, a Secret is stored in OpenStack Barbican in the respective OpenStack project, which is used for the encryption/decryption of the respective volume.
The corresponding storage classes can be referenced with the suffix -encrypted, for example general-purpose-1-encrypted, to obtain an encrypted volume of the general-purpose-1 storage class.
