General product information Network drives
The product is in beta testing mode. To access the service, make an application in the control panel: in the top menu, click Products → Dedicated servers → Network disks and storage → Network disks and storage → Network disks tab → 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 disks are available for connection to dedicated servers in the MSK-1 pool.You can connect a network disk to dedicated servers of a ready-made configuration with a tag You can also connect network disks to dedicated servers of an arbitrary configuration with an additional 2 × 10 GE NIC + 10 Gbps Network Disk SAN connection.
Principle of operation
The network disk can be connected to one or more dedicated servers.Connection is via iSCSI protocol.
All servers and network disks are combined into a single group when they are connected in the Control Panel — see the Connect a network disk to a server subsection of the Connect a network disk to a server instructions for details.A network disk can only be connected 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 performance.Suitable for operations that require high speed read and write.
Disk types are distinguished by minimum and maximum capacity limits, throughput values, and number of read and write operations.See the Network Disk Limits table for details.
