1 SFS

What Is SFS?

Scalable File Service (SFS) provides scalable, high-performance file storage. Withthe service, shared file access can be achieved among multiple Elastic CloudServers (ECSs), Bare Metal Servers (BMSs), and containers created on CloudContainer Engine (CCE). See Figure 1-1.

Figure 1-1 Accessing SFS

Compared with traditional file sharing storage, SFS has the following advantages:● File sharing

Scalable File ServiceService Overview 1 SFS

Issue 04 (2020-08-07) Copyright © Huawei Technologies Co., Ltd. 1

ECSs in multiple availability zones (AZs) of a same region can access thesame file system concurrently and share files.

● Elastic scalingStorage can be scaled up or down on demand to dynamically adapt to servicechanges without interrupting applications. You can complete resizing with afew clicks.

● Superior performance and reliabilityThe service enables file system performance to increase as capacity grows,and delivers a high data durability to support rapid service growth.

● Seamless integrationSFS supports Network File System (NFS). With this standard protocol, a broadrange of mainstream applications can read and write data in the file system.

● Easy operation and low costsIn an intuitive graphical user interface (GUI), you can create and manage filesystems with ease. SFS slashes the cost as it is charged on a pay-per-use basis.

Accessing SFSYou can access SFS on the management console or through APIs by sendingHTTPS requests.

● APIsCall APIs if you need to integrate SFS on the cloud service platform into athird-party system for secondary development. For detailed operations, seeScalable File Service API Reference.

● Management consoleYou can access SFS on the management console.

2 Region and AZ

Concept

A region and availability zone (AZ) identify the location of a data center. You cancreate resources in a specific region and AZ.

● Regions are divided based on geographical location and network latency.Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service(EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP(EIP), and Image Management Service (IMS), are shared within the sameregion. Regions are classified into universal regions and dedicated regions. Auniversal region provides universal cloud services for common tenants. Adedicated region provides specific services for specific tenants.

● An AZ contains one or more physical data centers. Each AZ has independentcooling, fire extinguishing, moisture-proof, and electricity facilities. Within anAZ, computing, network, storage, and other resources are logically dividedinto multiple clusters. AZs within a region are interconnected using high-speed optical fibers to support cross-AZ high-availability systems.

Figure 2-1 shows the relationship between regions and AZs.

Figure 2-1 Regions and AZs

HUAWEI CLOUD provides services in many regions around the world. Select aregion and AZ based on requirements. For more information, see HUAWEI CLOUDGlobal Regions.

https://www.huaweicloud.com/intl/en-us/global/

Selecting a RegionWhen selecting a region, consider the following factors:

● LocationIt is recommended that you select the closest region for low network latencyand quick access. Regions within the Chinese mainland provide the sameinfrastructure, BGP network quality, as well as resource operations andconfigurations. Therefore, if your target users are on the Chinese mainland,you do not need to consider the network latency differences when selecting aregion.– If your target users are in Asia Pacific (excluding the Chinese mainland),

select the AP-Hong Kong, AP-Bangkok, or AP-Singapore region.– If your target users are in Africa, select the AF-Johannesburg region.– If your target users are in Europe, select the EU-Paris region.– If your target users are in Latin America, select the LA-Santiago region.

NO TE

The LA-Santiago region is located in Chile.

● Resource priceResource prices may vary in different regions. For details, see Product PricingDetails.

Selecting an AZWhen deploying resources, consider your applications' requirements on disasterrecovery (DR) and network latency.

● For high DR capability, deploy resources in different AZs within the sameregion.

● For low network latency, deploy resources in the same AZ.

Regions and EndpointsBefore you use an API to call resources, specify its region and endpoint. For moredetails, see Regions and Endpoints.

3 Application Scenarios

SFS Capacity-Oriented

Expandable to petabytes, SFS Capacity-Oriented provides fully hosted shared filestorage. It features high availability and durability, and seamlessly handles data-intensive and bandwidth-intensive applications. It is suitable for multiple scenarios,including high-performance computing (HPC), media processing, file sharing, aswell as content management and web services.

● HPCIn industries that require HPC, such as simulation experiments, biopharmacy,gene sequencing, image processing, and weather forecast, SFS providessuperb compute and storage capabilities, as well as high bandwidth and lowlatency.

● Media processingServices of TV stations and new media are more likely to be deployed oncloud platforms than before. Such services include streaming media, archiving,editing, transcoding, content distribution, and video on demand (VoD). Insuch scenarios, a large number of workstations are involved in the wholeprogram production process. Different operating systems may be used bydifferent workstations, requiring file systems to share materials. In addition,HD/4K videos have become a major trend in the broadcasting and TVindustry. Taking video editing as an example, to improve audiences'audiovisual experience, HD editing is being transformed to 30- to 40-layerediting. Therefore, a single editing client may require a file system with abandwidth up to hundreds of MB per second. Usually, producing a single TVprogram needs several editing clients to process a lot of video materialsconcurrently. To meet such requirement, SFS provides customers with stable,bandwidth-intensive, and latency-sensitive performance.

● File sharingFor an organization with a large number of staff, SFS can create shared filesystems that are accessible to all staff, to facilitate file sharing among staff.

● Content management and web serviceSFS can be used in various content management systems to store and provideinformation for websites, home directories, online releases, and archiving.

● Big data and analytic applications

6 Basic Concepts

Before you start, understand the following concepts.

● NFSNetwork File System (NFS) is a distributed file system protocol that allowsdifferent computers and operating systems to share data over a network.

● File systemA file system provides users with shared file storage service through NFS. It isused for accessing network files remotely. After a user creates a mount pointon the management console, the file system can be mounted to multiple ECSsand is accessible through the standard POSIX.

● POSIXPortable Operating System Interface (POSIX) is a set of interrelated standardsspecified by Institute of Electrical and Electronics Engineers (IEEE) to definethe application programming interface (API) for software compatible withvariants of the Unix operating system. POSIX is intended to achieve softwareportability at the source code level. That is, a program written for a POSIXcompatible operating system may be compiled and executed on any otherPOSIX operating system.

● DHCPDynamic Host Configuration Protocol (DHCP) is a LAN network protocol. Theserver controls an IP address range, and a client can automatically obtain theIP address and subnet mask allocated by the server when logging in to theserver. By default, DHCP is not automatically installed as a service componentof Windows Server. Manual installation and configuration are required.

● ProjectA project is used to group and isolate OpenStack resources, such as compute,storage, and network resources. A project can be a department or a projectteam. More than one project can be created for an account.

8 Billing

Billing Items of SFS Capacity-OrientedThe default billing mode is pay-per-use. With this billing mode, creating filesystems is free of charge and your service account is only billed for the amount oftime (hours) resources used for. There is no minimum billing threshold. A durationof less than one hour is rounded up to an hour. For details about SFS billing, seeTable 8-1.

Table 8-1 SFS billing

Category Billing Item Billing Formula Description

Scalable File ServiceService Overview 8 Billing


Billing ModesSFS provides two billing modes: pay-per-use and yearly/monthly. For details abouthow to purchase SFS, see How Do I Purchase SFS?

For details about the billing, see Product Pricing Details.

In addition, you can use the Price Calculator to quickly calculate an estimatedprice for the resources that you select.

Changing Billing Mode● Yearly/monthly is a prepaid billing mode. You will be billed based on the

subscription duration you specify. This mode provides a favorable price and isideal when the resource use duration is predictable.

● Pay-per-use is a postpaid billing mode. You will be billed based on the billingitems of specific file systems and can purchase or delete file systems at anytime. Fees are deducted from the account balance.

SFS Capacity-Oriented file systems support the change from pay-per-use billing toyearly/monthly billing while SFS Turbo file systems do not. For details, see Yearly/Monthly Subscription. Currently, the billing mode cannot be changed fromyearly/monthly to pay-per-use.

The purchased SFS resource packages cannot be viewed on SFS Console. Fordetails about how to view the resource packages, see How Do I View the Usageof a Resource Package? The capacity of the resource packages is preferentiallyused when you use the file systems.

RenewalFor more information about renewal, including auto-renewal, exporting therenewal list, and changing subscriptions, see Renewal Management.

ExpirationAfter a yearly/monthly file system expires, you will be billed for subsequently usedresources on a pay-per-use basis. If your account is in arrears, you need to pay offthe arrears in a timely manner. For details about how to repay the arrears, seeRepaying Arrears. If you do not pay off the arrears in a timely manner, thesystem processes the resource based on the Service Suspension and ResourceRelease. If the resource package is not renewed before the retention periodexpires, the system automatically deletes the resource.

Overdue PaymentPossible causes of overdue payment:

● You have purchased an SFS Capacity-Oriented resource package, but theusage of the SFS Capacity-Oriented file system exceeds the quota of theresource package. In addition, your account balance is insufficient to deductthe pay-per-use fees generated when the quota is exceeded.

● You have purchased an SFS Capacity-Oriented resource package but created apay-per-use SFS Turbo file system. In addition, your account balance isinsufficient to deduct the generated pay-per-use fees.

Service status and operation restrictions when an account is in arrears:

If an account is in arrears, the retention period varies depending on the customertier. If your account is in the retention period, your file system will be retained butyou cannot continue to use the file system. For details about arrears payment, seeRepaying Arrears. If you do not pay off the outstanding fees within the retentionperiod, your data will be automatically released and cannot be restored.

For details about the retention period, see Retention Period.





9 Permissions Management

If you need to assign different permissions to employees in your enterprise toaccess your SFS resources on , Identity and Access Management (IAM) is a goodchoice for fine-grained permissions management. IAM provides identityauthentication, permissions management, and access control, helping you secureaccess to your resources.

With IAM, you can use your account to create IAM users, and assign permissionsto the users to control their access to specific resources. For example, somesoftware developers in your enterprise need to use SFS resources but should notbe allowed to delete the resources or perform any other high-risk operations. Inthis scenario, you can create IAM users for the software developers and grantthem only the permissions required for using SFS resources.

If your account does not require individual IAM users for permissionsmanagement, skip this section.

IAM can be used free of charge. You pay only for the resources in your account.For more information about IAM, see IAM Service Overview.

SFS Permissions

By default, new IAM users do not have permissions assigned. You need to add auser to one or more groups, and attach permissions policies or roles to thesegroups. Users inherit permissions from the groups to which they are added andcan perform specified operations on cloud services based on the permissions.

SFS is a project-level service deployed and accessed in specific physical regions. Toassign SFS permissions to a user group, specify the scope as region-specificprojects and select projects for the permissions to take effect. If All projects isselected, the permissions will take effect for the user group in all region-specificprojects. When accessing SFS, the users need to switch to a region where theyhave been authorized to use this service.

You can grant users permissions by using roles and policies.

● Roles: A type of coarse-grained authorization mechanism that definespermissions related to user responsibilities. This mechanism provides only alimited number of service-level roles for authorization. When using roles togrant permissions, you need to also assign other roles on which the

Scalable File ServiceService Overview 9 Permissions Management


https://support.huaweicloud.com/intl/en-us/productdesc-iam/iam_01_0026.html

permissions depend to take effect. However, roles are not an ideal choice forfine-grained authorization and secure access control.

● Policies: A type of fine-grained authorization mechanism that definespermissions required to perform operations on specific cloud resources undercertain conditions. This mechanism allows for more flexible policy-basedauthorization, meeting requirements for secure access control. For example,you can grant ECS users only the permissions for managing a certain type ofECSs. Most policies define permissions based on APIs. For the API actionssupported by SFS, see Permissions Policies and Supported Actions.
