Availability
Local SSD disks are available only in theuk-south1 region, on the NVIDIA® B300 NVLink with Intel Granite Rapids platform (gpu-b300-sxm) with the eight-GPU preset 8gpu-192vcpu-2768gb.
Their capacity is fixed by the selected platform and preset. This configuration adds 6 × 3.84 TB of local storage.
How to add local SSD disks
Local SSD disks can be enabled when creating a VM. They are not created as a separate storage resource, and you cannot add them to an existing VM or change this setting later. You can create RAID on top of your local SSD disks, for example, to combine multiple disks into a single logical storage for higher performance or easier management.Lifecycle and data persistence
Local SSD data persistence depends on whether the event affects the Compute VM or only the VM operating system:- If you reboot the VM operating system from inside the VM, for example by using
sudo reboot, data is expected to persist because the Compute VM is not stopped or deleted. - If you stop or delete the VM in Compute, data on local SSD disks is lost.
- If the host or a local disk fails, the Compute VM enters maintenance mode and data is lost.
When to use durable storage instead
Use durable storage instead of local SSD disks if you need any of the following:- Data that must survive VM stop, deletion or rescheduling events. Use Network disks, shared filesystems or Object Storage.
- Data sharing across several VMs. Use shared filesystems or Object Storage.
- Snapshots, backup workflows or long-term retention. Use Network disks, shared filesystems or Object Storage.
- User-defined capacity that is independent of the selected VM preset. Use Network disks or shared filesystems.
