Use CFS File System （Windows）

1. Creating and Configuring a CVM Instance

To access the file system, you need to mount the file system to Linux- or Windows-based Tencent Cloud CVM instances. In this step, you will create and configure a Windows-based Tencent Cloud CVM instance. If you want to use a Linux-based CVM, please see Creating a Network File System (Linux) with CFS. If a CVM instance has been created, go to Step 2 Create a File System and Mount Point.

Go to the Tencent Cloud official website, select Cloud Products -> Compute and Network -> CVM, then click Buy Now to enter the CVM purchase page.

(1) Select a region and model

• Select a billing mode: Prepaid or postpaid (users who cannot purchase postpaid CVMs need to complete Identity Verification first). For more information, please see Billing Mode.
• Select a region and an availability zone: When you need more than one CVM, it is recommended that you choose different availability zones to implement disaster recovery.
• Select a model and configuration: For more information, please see Instance Types.

(2) Select an image

• Select an image provider.
  Tencent Cloud supports public images, custom images, shared images and service marketplace images. You can view Image Types to select an image. The public image type, which contain legitimate Windows operating system, is recommended for users who have just started using Tencent Cloud. You need to build subsequent operating environment on your own.
• Select an operating system: Windows Server.
• Select a system version.

(3) Select storage and network

• Select the type of disk and the size of data disk.
  Tencent Cloud provides two types of disks, cloud disk and local disk (system disk size is optional. The default is 50 GB).
  • Cloud disk: Deliver high data reliability with the distributed three-copy mechanism.
  • Local disk: A storage device on the physical machine where the CVM resides in, which allows low latency but may cause single point of failure risk.
• Select a network type.
  Tencent Cloud provides two network types: basic network and VPC.
  • Basic network: Suitable for new users. CVMs of the same user are interconnected via the private network.
  • VPC: Suitable for advanced users. Different VPCs are logically isolated from each other.
• Select the public network bandwidth.
  Tencent Cloud provides two options: Bill-by-bandwidth or bill-by-traffic.
  • Bill-by-bandwidth: Select a fixed bandwidth. Packet loss occurs if this bandwidth is exceeded. This is suitable for scenarios with minor network fluctuation.
  • Bill-by-traffic: The service is charged based on the actual traffic usage. You can set a limit for peak bandwidth to avoid extra fees caused by unplanned traffic. Packet loss occurs when the instantaneous bandwidth exceeds this limit. This is suitable for scenarios with large network fluctuations.
• Select the quantity.
• Select the usage period and renewal method (only for prepaid CVMs).

(4) Configure information

• Set CVM name: You can name it after creation or name it now.
• Set login information: You can set a password or use an automatically generated password. The password you set can be modified after creation of CVM. The automatically generated password is sent to you via the internal message.
• Select a security group (Make sure that the login port 3389 is enabled. For more information, please see Security Group).

Click Buy Now button to complete the payment before you can log in to the console to check your CVM.
After the CVM is created, you will receive an internal message containing such information as instance name, public IP address, private IP address, login name, and initial login password. You can use the information to log in to and manage instances.

2. Creating File System and Mount Point

1. Log in to the Tencent Cloud Console. Click Cloud Products -> Storage -> CFS to go to the CFS console.
   

2. In the Tencent Cloud CFS console, click Create and the Create File System popup window appears. Enter relevant information and confirm, and then click OK to create the file system.
   

   • Name: Name the file system to be created.
   • Region and availability zone: Choose a region closest to your customers to minimize access latency and improve download speed.
   • File protocol: NFS (suitable for Linux and Unix clients), CIFS/SMB (suitable for Windows clients).
   • Network type: Tencent Cloud provides two network types: basic network and VPC. Basic network is suitable for new users. CVMs of the same user are interconnected via the private network. VPC is suitable for advanced users. Different VPCs are logically isolated from each other.

   Note:
   Create and mount a file system based on the network where your CVM instance resides.

   • To allow a file system to be shared by CVMs under a VPC, you need to select VPC when creating a file system. When the file system belongs to VPC, only CVM instances in the same VPC can be mounted if no specific network settings are made.
   • To allow a file system to be shared by CVMs under a basic network, you need to select basic network when creating a file system. When the file system belongs to basic network, only CVM instances in the same basic network can be mounted if no specific network settings are made.
   • For more information on how to share a file system among multiple networks, please see Cross-availability zone and Cross-network Access to File System.

3. Obtain the mount point information. After the file system and the mount point are created, click the instance ID to enter the file system details page, and then click Mount Point Information to obtain the mount command for Windows.

The mount point information of NFS file system is as follows:

The mount point information of CIFS/SMB file system is as follows:

3. Connecting Instances

This section describes how to log in to a Windows CVM. Login method depends on the scenarios. This step shows how to log in to the CVM in the console. For more information on other login methods, please see Log in to Windows Instance.

Prerequisites
You need to use the admin account ID and the corresponding password to log in to the CVM.
