Connect a network drive to a dedicated Windows server
For more information about network drives in the instructions General product information Network drives.
- Create a SAN.
- Connect the network drive to the server.
- Connect the network volume to the server in the server OS.
- Configure MPIO.
- Optional: connect the network drive to another server.
- Prepare the network drive for operation.
1. Create a SAN network
-
In the Control Panel, on the top menu, click Products and select Dedicated Servers.
-
Go to Network → SAN tab.
-
Click Add SAN.
-
Select an availability zone.
-
Enter a subnet address from the private address range
10.0.0.0/8,172.16.0.0/12,192.168.0.0/16) or leave the subnet that is generated by default.The subnet size should be/20.
Make sure the subnet is not being used in your infrastructure. -
Click Create SAN.
2. Connect the network drive to the server
-
In the Control Panel, on the top menu, click Products and select Dedicated Servers.
-
Go to network volumes and Storage → network volumes tab.
-
Open the disk page → Server Connection tab.
-
In the Server field, click Select.
-
Select the server to which the network drive will be connected.
-
Click Confirm.
-
If you are connecting a network drive to a server with a private network, configure the network:
7.1 Select VLAN.
7.2 Enter the subnet CIDR from the private address range
10.0.0.0/8,172.16.0.0/12, or192.168.0.0/16..
Verify that the subnet does not overlap with the SAN that you created in step 1 and you are not using it in your infrastructure.7.3 Enter the Next hop 1 and Next hop 2 addresses from the selected private subnet.
7.4. Click Customize.
3. Connect the network volume to the server in the server OS
You can connect a network disk to the server manually or with the help of a ready-made script, which is formed in the control panel.You can use the script only on Ubuntu OS - more details in the instructions Connect a network disk to a dedicated server with Linux OS.
If your server is running Hyper-V, the network disk will not work.This is because the disk over an iSCSI connection does not support the SCSI-3 Persistent Reservations required for Hyper-V to run in Failover Cluster mode.
The process of connecting a network volume in the server OS through a private subnet depends on the number of ports:
- if the server has two local ports, use the instruction for two ports;
- If the server has only one local port or MC-LAG is configured, use the instructions for a single port.
SAN network
Private network: one port
Private network: two ports

If the status of the network drive is
Offline, change it toOnline:Set-Disk -Number <block_storage_number> -IsOffline $falseSpecify
<block_storage_number>is the network drive number you obtained in step 18. -
Initialize the network drive:

<block_storage_number>is the network drive number you obtained in step 18. -
If you are connecting a network drive to the server for the first time, create and format a partition on the network drive:
21.1 Create a partition on the network drive:
New-Partition -DiskNumber <block_storage_number> -UseMaximumSize -AssignDriveLetterSpecify
<block_storage_number>is the network drive number you obtained in step 18.21.2 Format the network volume partition to the desired file system:

If you are connecting the network volume to only one server, format the network volume partition to the NTFS file system:
Format-Volume -DriveLetter <volume_letter> -FileSystem NTFS -NewFileSystemLabel "<label>"Specify:
<volume_letter>- volume letter;<label>- label of the file system (volume).
-
If you are connecting a single network drive to two or more servers, you must use the ReFS file system in conjunction with CSV (Cluster Shared Volumes) - see the Resilient File System (ReFS) overview article in the Microsoft documentation for more information.
-
4. Customize MPIO
MultiPath-IO (MPIO) - Multi-path I/O to improve the fault tolerance of data transfer to a network volume.
-
Disable iSCSI sessions:
$session = Get-IscsiSession -
Install the MPIO components:
Install-WindowsFeature Multipath-IO -
Turn on the MPIO:
Enable-WindowsOptionalFeature -Online -FeatureName MultiPathIO -
Get a list of devices that support MPIO:
mpclaim.exe -eThe command output will display devices that support MPIO.For example:
"Target H/W Identifier " Bus Type MPIO-ed ALUA Support-------------------------------------------------------------------------------"LIO-ORG TCMU device " iSCSI NO Implicit OnlyHere
LIO-ORG TCMU deviceis the network disk ID. -
Enable MPIO support for the network drive:
mpclaim.exe -r -i -d "<block_storage_device>"Specify
<block_storage_device>is the network disk ID you obtained in step 4. Note that the ID must be entered with spaces. -
Check the status of the MPIO:
Get-MPIOAvailableHWThe command output displays the MPIO status for the network drive.For example:
VendorId ProductId IsMultipathed IsSPC3Supported BusType-------- --------- ------------- --------------- -------LIO-ORG TCMU device True True iSCSIHere, the
IsMultipathedfield displays the status of the MPIO. -
Ensure that the MPIO device path accessibility check mechanism is enabled:
(Get-MPIOSetting).PathVerificationStateThe command output will display the status of the MPIO device path accessibility mechanism.For example:
Enabled -
If the MPIO device path accessibility check mechanism is in
Disabledstatus, enable it:Set-MPIOSetting -NewPathVerificationState Enabled -
Associate the volumes on the network volume with logical partitions in the server OS:
iscsicli.exe BindPersistentDevices -
Allow the server OS to access the contents of the network volume volumes:
iscsicli.exe BindPersistentVolumes -
Make sure that the network drive is registered as a persistent device in the server OS configuration:
iscsicli.exe ReportPersistentDevicesThe response will show information about the network drive as a persistent device.For example:
Persistent Volumes"D:\"Here,
D:\is a volume on the network drive.
5. Optional: Connect the network drive to another server
- Connect the network drive to the server in the control panel.
- Connect the network disk to the server in the server OS.
- Configure MPIO.
6. Prepare the network drive for operation
You can format the network volume that you connected to the server to the desired file system:
- ReFS (Resilient File System) is a fault-tolerant file system designed to improve data availability, scale large datasets across workloads, and provide data integrity with resistance to corruption.If you are connecting a single network drive to two or more servers, you must use the ReFS file system in conjunction with CSV (Cluster Shared Volumes) - see the Resilient File System (ReFS) overview article in the official Microsoft documentation for more information;
- A standard file system such as NTFS (New Technology File System).Note, NTFS file system does not support simultaneous read-write access from multiple servers to avoid data corruption.To share multiple servers, use specialized file systems.
