General information about the Network Disk Service

For your information

The service is in beta testing mode.

Network Disk is a scalable external network block storage with triple data replication. Triple replication of disk volumes provides high data integrity. Suitable for rapid scaling of server disk space.

The network drive can only be connected to to a dedicated off-the-shelf configuration server with a network card to the SAN. A network disk can only be connected to one server, and multiple network disks can be connected to one dedicated server. The connection is made using the iSCSI protocol.

Types of network disks

Selectel provides two types of network disks:

  • Basic HDD — HDD disk based on enterprise-class SATA disks. Suitable for storing large amounts of data that do not need to be read or rewritten frequently;
  • Fast SSD — NVMe SSD disk with fast response and high speed operation. Suitable for operations that require high read and write speeds.

Disk types are distinguished by minimum and maximum capacity limits, throughput values, and number of read and write operations. See the table for details Network disk limits.
