NFS

NFS protocol overview

You can use the protocol service to access vePFS file storage directly via NFSv3 protocol. This article introduces the supported specifications, usage restrictions, and usage procedures of the protocol service.

Notice

The NFS protocol feature is currently in beta. If you need to use this feature, submit a ticket or contact your account manager.

Specifications

The currently supported NFS specifications and descriptions are as follows. When data is cached, vePFS provides higher intranet bandwidth according to the specifications. Prices vary depending on specifications and bandwidth. Refer to the console for accurate pricing.

Protocol type	Specifications	Supported file system specifications	Performance description	Billing
Network File System (NFS)	Cache Type 1	100 MB/s/TiB Performance_Edition Intelligent computing edition	Read bandwidth (MB/s): Supported range is [8000, 128000], with increments of 4000 Cache: Supports 410 GiB	Billing method: Pay-as-you-go Cost: 5.4 CNY/GBps/hour
Network File System (NFS)		Cache Type 2	100 MB/s/TiB Performance_Edition Intelligent computing edition	Billing method: Pay-as-you-go Cost: 5.4 CNY/GBps/hour	Read bandwidth (MB/s): Supported range is [16,000, 128,000], in increments of 8,000 Cache: Supports 1230 GiB

Usage

Limit	Restrictions
Number of protocol services that can be created in a single file system	1 instance.
Number of VPCs exportable by a single protocol service	1.
Number of export directories that can be created for a single protocol service	1.
Protocol type	Only supports the NFSv3 protocol and does not support the NFSv4.x protocol.
Operating systems	Accessing file systems via NFS protocol on Windows operating systems is not recommended.
Feature description	The POSIX permission bits (SetUID, SetGID, and Sticky Bits) are not supported. File locking is not supported. Posix ACL is not supported. Currently, export directories can only be created within the same VPC on vePFS.
File amount limitation	An NFS client can open up to 32,768 files at the same time. The list directory and its files will not be counted as open files.
Maximum file name length	255 bytes.
Maximum number of open files	1 million.
Number of compute nodes that can be mounted by a single protocol service	10,000.

Workflow

After creating a protocol service, you can create export directories and mount file systems.
