Overview

Alibaba Cloud File Storage NAS is a file storage service for Alibaba Cloud ECS instances, Alibaba Cloud E-HPC and Container Service. It provides standard file access protocols, so you do not have to modify existing applications. This enables you to have a distributed file system with unlimited capacity and performance scaling, with a single namespace, multi-party sharing, high reliability, and high availability.

Benefits

High Performance High IOPS, low latency, and high throughput Meets various business needs High Reliability Provides a data reliability of 99.999999999% Secure Multiple security mechanisms Account authorization, VPC, and security group ACL Ease of Use Supports standard NFS, SMB protocols No modifications need to be made to your applications

Features

High Performance, High Reliability, and High Availability

Based on the newest distributed storage system, NAS maintains a low latency and high IOPS High performance Based on RoCE and NVMe SSDs, NAS reduces network latency and provides high performance. High reliability Maintains multiple data replicas and a data reliability of 99.999999999%. NAS is more reliable than traditional RAID arrays. High availability Avoids single points of failure and maintains a data availability of 99.9%.

Unlimited, Elastic Storage

Elastic scaling provides great scalability to meet your needs Unlimited storage capacity The maximum capacity of a file system can reach 10 PB. Each file system can store a maximum of 1 billion files, and the maximum file size is 32 TB. Elastic scaling Storage scales automatically and is billed accordingly. This is a fully hosted solution that needs no upfront cost.

Ease of Use. You Can Perform File Operations as If the Files Were Locally Stored

Supports POSIX interfaces. No modifications need to be made to your applications. Simple and easy to use Supports standard POSIX interfaces. Both Windows and Linux applications can use this service without any modifications. System mounting You can mount the file system on ECS compute nodes. This allows you to perform file operations as if the files were locally stored.

Supports Various Standard Protocols

Supports standard NFS and SMB protocols. Both Windows and Linux applications can use this service. NFS Supports the NFSv3 and NFSv4 protocols and provides standard file system semantics for data access. Most mainstream applications and tasks can be seamlessly integrated with the service without any modifications. SMB Supports the SMBv2.0, SMBv2.1, and SMBv3.0 protocols. Supports the applications that are deployed on Windows Vista, Windows Server 2008 and later versions.

Strong Security Control

Mechanisms such as account authorization, VPC, and security groups ensure your data security. Data security Multiple security mechanisms are implemented to guarantee system data security, including network isolation (VPC) and user isolation (classic network), standard access control, permission groups, and account authorization.

Multiple Access Methods

Supports classic network and VPC, and allows access from remote data centers. Shared access Multiple compute nodes can simultaneously access the same file system, allowing applications deployed across multiple ECS instances, E-HPC or Docker clusters to access the same data source. Multiple access methods The NAS file system can be deployed in a classic network or a VPC. You can also access the file system from remote data centers through leased lines or VPN. Access across multiple zones Supports access from different zones. Your ECS instance and NAS file system can be deployed in different zones.
