General product information Network drives

For your information

The product is in beta testing mode. To access the service, please make an application at control panels: from the top menu, press ProductsDedicated serversNetwork disks and storage → tab Network disks → click Connect.

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.

Network drives are available for connection to dedicated servers в bullet MSK-1. You can connect the network disk to dedicated servers of a ready configuration with the tag You can connect network drives and to dedicated servers of arbitrary configuration with an additional 2 × 10 GE network card + connection to a SAN network of 10 Gbps network disks.

Principle of operation

The network drive can be connected to one or more dedicated servers. The connection is made using the iSCSI protocol.

All servers and network disks are combined into a single group when they are joined in the control panel — more details in the subsection Connect the network drive to the server instructions Connect a network disk to a server. You can only connect the network disk to the entire group at once — it will be available to all servers in the group.

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.
