Local Disks

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

The local disk 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 disk is not a required configuration parameter. The cloud server can be created without it.

Local disks 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 disks from a cloud server and attach to another;
• only one local disk can be connected to the cloud server;
• 2 TB is the recommended limit for the local disk;
• resizing the local disk takes longer than resizing the network volume;
• you cannot create a snapshot of the local disk.
