Local Volumes

The local volume is always a system (boot) volume. Due to the lack of network delays, the local volume is suitable for workloads where read and write speed indicators are important.

The local volume has a PCIe connection interface over the NVMe protocol and is physically connected directly to the computing server, so it can only be created when creating a server. The local volume is not a required configuration parameter. The cloud server can be created without it.

Local volumes have the following features:

  • performance: read 12800 IOPS / write 6400 IOPS;
  • bandwidth: 300 Mbps;
  • disk subsystem configured in RAID10;
  • can only be a boot volume of the server and is not used as an additional volume — only network volumes can be connected as additional ones;
  • it is impossible to detach local volumes from a cloud server and attach to another;
  • only one local volume can be connected to the cloud server;
  • 2 TB is the recommended limit for the local volume;
  • resizing the local volume takes longer than resizing the network volume;
  • you cannot create a snapshot of the local volume.
