Product Description Network disks for dedicated servers
The Dedicated Server 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 volumes can be connected to dedicated servers in pools:
- MSK-1 - over the SAN network and through the private network;
- MSK-2 is via private network only.
Dedicated servers are available to connect to network volumes:
- arbitrary and off-the-shelf 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 → Server page → Ports tab;
- ready configuration with the tag You can connect network volumes;
- custom configuration with optional 2 × 10 GE NIC + 10 Gbps network volume SAN connection.
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 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
Servercore 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 size limits, throughput values, and number of read and write operations. See the Network Disk Limits table for details.
