Storage
Project storage pool view and per-disk IOPS / throughput limits for VM virtual disks.
Read-only view of a project storage pool in the console, plus the performance limits applied to each VM virtual disk.
Overview
See which VM virtual disks are on a given storage pool — disk capacity is billed in the project.
VM system disks use distributed all-flash NVMe storage. See Platform capabilities for architecture notes (RoCEv2, io_uring, latency reference).
Disk performance limits
Every virtual disk is capped at the hypervisor with fixed IOPS and throughput limits. The values are the same for all VMs and are not configurable in the portal.
| Limit | Value |
|---|---|
| Read IOPS | 15,000 |
| Write IOPS | 15,000 |
| Read throughput | 500 MB/s |
| Write throughput | 500 MB/s |
Watch out
Additional VM disks are not available in the portal. Increase the system disk on Resize a VM.
