1.1 What Is SFS?

Scalable File Service (SFS) provides high-performance le storage that can be expanded and shrunk on demand. With SFS, you can enjoy shared spanning multiple ECSs. SFS supports the Network File System (NFS) protocol. You can seamlessly integrate existing applications and tools with the service.

SFS provides an easy-to-use graphical user interface (GUI). On the GUI, users can create and optimizing

In addition, SFS features high reliability and availability. It can be elastically expanded, and it performs better as its capacity grows. The service is suitable for a wide range of scenarios, including media processing, management and web services, big data, and analytic applications.

4.1 Can a File System Be Accessed Across VPCs?

Yes.

● Multiple VPCs can be that ECSs belonging to dierent VPCs can share the same le system, as long as the VPCs that the ECSs belong to are added to the VPC list of the le system or the ECSs are added to the authorized addresses of the VPCs. For details, see Conguring Multiple VPCs.

● An SFS Turbo interconnect with each other through VPC peering connection. In this case, dierent VPCs are in the same network, and ECSs under these VPCs can share the same le system. For details about VPC peering connection, see VPC

4.3 Does the Security Group of a VPC Aect SFS?

A security group is a collection of access control rules for ECSs that have the same security protection requirements and are mutually trusted in a VPC. After a security group is created, you can create group to protect the ECSs that are added to this security group. The default security group rule allows all outgoing data packets. ECSs in a security group can access each other without the need to add rules. The system creates a security group for each cloud account by default. Users can also create custom security groups by themselves.

Scalable File Service FAQs 4 Networks

After an SFS Turbo le system is created, the system automatically enables the security group port required by the NFS protocol in the SFS Turbo le system. This ensures that the SFS Turbo le system can be accessed by your ECS and prevents le system mounting failures. The inbound ports required by the NFS protocol are ports 111, 2049, 2051, 2052, and 20048. If you need to change the enabled ports, choose Access Control > Security Groups of the VPC console and locate the target security group.

You are advised to use an independent security group for an SFS Turbo instance to isolate it from service nodes.

You need to add inbound and outbound rules for the security group of an SFS Capacity-Oriented

le system. For details, see Adding a Security Group Rule. In an SFS Capacity-Oriented le system, the inbound ports required by the NFS protocol are ports 111, 2049, 2051, and 2052. The inbound port required by the DNS server is port 53.

4.4 What Can I Do If the Data of the File System That Is Mounted to Two Servers Is Not Synchronized?

Symptom

When le system C is mounted to both server A and server B, there is a delay in synchronizing the no delay when the le is uploaded to server B separately.

Fault Diagnosis

Add noac to the mount parameters of the two servers. noac indicates that cache is disabled and synchronous write is forcibly performed. To improve performance, the NFS client caches le properties periodically and updates them if the properties are changed. Within the cache validity period, the client does not check whether the le properties on the server are changed. The default value is ac. Set this parameter to noac.

The SFS Capacity-Oriented resource package takes eect immediately after being purchased. If the capacity of the resource package is greater than the le system usage, the pay-per-use billing mode stops immediately. The capacity of the resource packages is preferentially used when you use the le systems.

SFS resource packages cannot be expanded, but can be purchased multiple times. For details, see Can I Purchase SFS Capacity-Oriented Resource Packages When I Still Have

Valid Ones in Use?.

For example, if a user purchases a 1 TB SFS Capacity-Oriented resource package for one year and creates a 500 GB SFS Capacity-Oriented le system (le system A) on SFS Console, the used capacity of the resource package is 500 GB. For details about how to view the usage of the resource package, see How Do I View the Usage of a Resource Package? One month later, the user creates another 600 GB SFS Capacity-Oriented le system (le system B). Now the purchased 1 TB capacity is used up, and 100 GB beyond the capacity is billed in pay-per-use mode. If you do not want to be billed in pay-per-use mode, you can purchase more resource packages.

6.5 How Can I Migrate Data Between SFS and OBS?

Background

HUAWEI CLOUD Object Storage Service (OBS) is a stable, secure, easy-to-use cloud storage service. With the Representational State Transfer (REST) application programming interfaces (APIs), OBS is able to store any amount and form of unstructured data.

HUAWEI CLOUD Scalable File Service (SFS) is a network attached storage (NAS) service that provides scalable high-performance access can be achieved among multiple Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), and containers created on Cloud Container Engine (CCE) and Cloud Container Instance (CCI).

How to Migrate

SFS between SFS and OBS is actually the data migration between servers/containers and OBS. Data in servers or containers is stored in the mounted SFS

Therefore, after an SFS le system is mounted to a server or container, you can log in to the server or container and use OBS tools, APIs, or SDKs to migrate data. For example, if you want to migrate data from SFS to OBS, use the OBS upload function on the server or container to upload data to OBS. If you want to migrate data from OBS to SFS, use the OBS download function on the server or container to download data to the SFS and write permissions are required.

6.6 Can a File System Be Accessed Across Multiple AZs?

1. A single le system can be created only in one AZ, for example, AZ 1, but can be mounted to and accessed from any AZ.

2. A le system does not support data redundancy across AZs. If the AZ where a le system resides is unavailable, the le system is unavailable.

6.7 Can I Upgrade an SFS Capacity-Oriented File System to an SFS Turbo File System?

No. If you want an SFS Turbo le system, you need to delete or unsubscribe from the SFS Capacity-Oriented

le system and purchase an SFS Turbo le system.

6.8 How Can I Migrate Data Between SFS and EVS?
