Product Description Network Volumes for Dedicated Servers
A network volume for dedicated servers is a scalable external network block storage with triple data replication. Triple replication of disk volumes ensures high data integrity. It is suitable for rapidly scaling server disk space.
Network volumes can be connected to dedicated servers in pools:
- MSK-1 — via SAN and the private network;
- MSK-2 — over the private network only.
Dedicated servers are available to connect to network volumes:
- custom and ready-made configuration with a port for the local network. You can view information about server ports in the Control Panel: in the top menu, click Products → Dedicated Servers → Servers → server page → tab Ports;
- ready configuration with the tag You can connect network volumes;
- custom configuration with an additional 2 × 10 GE NIC + 10 Gbps network volume SAN connection.
How it works
A network volume can be connected to one or more dedicated servers. Connection is performed via the iSCSI protocol.
All servers and network volumes are combined into a single group when they are connected in the Control Panel — see the Connect network volume to server subsection of the Connect a network volume to a server instructions for details. A network volume can be connected only to the entire group at once — it will be available to all servers in the group.

Types of network volumes
Selectel provides two types of network volumes:
- Basic HDD – an HDD based on enterprise-class SATA disks. Suitable for storing large volumes of data that do not need to be frequently read or overwritten;
- Fast SSD – an NVMe SSD with fast response times and high performance. Suitable for operations that require high read and write speeds.
Disk types differ in their minimum and maximum size limitations, throughput values, and the number of read and write operations. See additional info in the Network volume limits table.
