Apsara File Storage NAS:Extreme NAS file systems

Last Updated:May 10, 2024

Extreme NAS is a high-performance file sharing service based on the latest network architecture and all-flash storage. The fully managed cloud storage service is integrated with the computing services of Alibaba Cloud to provide optimal computing performance for public cloud. Extreme NAS file systems feature low latency, high IOPS, and large capacity. Extreme NAS file systems are suitable for latency-sensitive Linux applications for enterprises, development and test environments for continuous integration and continuous deployment (CI/CD), and high-performance web services. This topic describes the performance metrics, supported file protocols, supported regions, and advanced features of Extreme NAS file systems.

Performance metrics

After January 19, 2024

Note

From January 19, 2024, the maximum bandwidth of advanced Extreme NAS file systems is increased to 4,000 MB/s in some regions. The maximum bandwidth in other regions remains unchanged. If your file system was created before January 19, 2024, the bandwidth of the file system is not directly upgraded. If you want to use a higher bandwidth, we recommend that you create an Extreme NAS file system and migrate data from the existing file system to the new file system. For more information, see Migrate data between NAS file systems.

IOPS

The IOPS increases as the storage capacity of the file system increases. If the I/O size is 4 KiB, you can use the following formulas to calculate the read and write IOPS:

  • Read IOPS = min{5000 + 50 × Capacity (GiB),200000}

  • Write IOPS = min{2500 + 25 × Capacity (GiB),100000}

The IOPS increases as the storage capacity of the file system increases. If the I/O size is 4 KiB, you can use the following formulas to calculate the read and write IOPS:

  • Read IOPS = min{7000 + 30 × Capacity (GiB),200000}

  • Write IOPS = min{3500 + 15 × Capacity (GiB),100000}

Access control

RAM-based access control

Resource Access Management (RAM) is a service provided by Alibaba Cloud to manage access permissions on resources. RAM policies are user-based authorization policies. You can configure RAM policies to manage your users, such as employees, systems, and applications, and manage user permissions on your resources. For example, you can configure a RAM policy to grant users only the read permissions on a specific file system.

Perform access control based on RAM policies

Data security

Data encryption

Extreme NAS file systems support server-side encryption. Server-side encryption uses the industry-standard AES-256 algorithm to generate keys. These keys are used to protect static data in file systems. To prevent against unauthorized data access, server-side encryption uses the envelope encryption mechanism.

Server-side encryption

Data management

Snapshots

Advanced Extreme NAS file systems support the snapshot feature. You can use the snapshot feature to restore data from a snapshot of a specified point in time to an existing file system. You can also restore data across zones.

Manage snapshots

Data backup

NAS allows you to use Cloud Backup to back up files in NAS file systems at regular intervals and restore files when data is lost or damaged.

Back up an Extreme NAS file system

Data migration

NAS allows you to migrate data from an on-premises storage system to NAS or from NAS to other storage media.

Scenarios

Extreme NAS file systems provide benefits such as low latency, high IOPS, and high capacity. Extreme NAS file systems are suitable for latency-sensitive Linux applications for enterprises, development and test environments for continuous integration and continuous deployment (CI/CD), and high-performance web services.

Note
  • The advanced edition of Extreme NAS file systems is unavailable in some zones due to infrastructure constraints. In this case, you can select the standard edition instead. For more information about the regions supported by each storage class, see Supported regions and zones.

  • We recommend that you create an Extreme NAS file system in the zone where your business data resides.

  • You cannot change the edition of an Extreme NAS file system from standard to advanced.

Supported regions and zones

Extreme NAS provides two storage classes: standard and advanced. The following table lists the regions and zones supported by each storage class.

Advanced

From January 19, 2024, the maximum bandwidth of advanced Extreme NAS file systems is increased to 4,000 MB/s in some regions. The maximum bandwidth in other regions is still 1,200 MB/s. The following tables list the regions and zones that are supported by the two bandwidth types.

Suggestions

Scenario 1

Issue: A large number of clients concurrently create and delete files in the same directory of an Extreme NAS file system. The performance deteriorates when files in the directory are accessed.

Suggestion: We recommend that you set the number of clients that can concurrently create and delete files in the same directory of an Extreme NAS file system to 10 or less.

Scenario 2

Issue: After a large number of files are stored in an Extreme NAS file system, the latency of accessing files in a large directory that stores a large number of files increases. In extreme cases, it is mistakenly considered as no I/O response.

Suggestion: If the number of files in a single Extreme NAS file system exceeds 20 million, we recommend that you store no more than 10,000 files or subdirectories in a single directory.
