Max. number of clients per file system |
10,000 |
Max. capacity per file system |
4 PB |
Max. size of a single file |
240 TB |
Multi-VPC access |
Supported. You can add a maximum of 20 VPCs for one file system and create a maximum of 400 ACL rules for all added VPCs. |
Max. enterprise projects supported |
20. If there are more than 20 enterprise projects, SFS Capacity-Oriented file systems may fail to be created. SFS Turbo is recommended. |
Replication |
Not supported |
Cross-region mounting |
Not supported |
Cross-account mounting |
Not supported |
SFS Capacity-Oriented file systems are now sold out. You can use General Purpose File System or SFS Turbo.
General Purpose File System
Item |
Description |
---|---|
Access method |
Can only be accessed over the intranet. |
Supported protocols |
Only NFSv3 is supported (NFSv4 is not supported). |
Max. number of clients per file system |
10,000 |
File system encryption |
Not supported |
Number of files or subdirectories in a file system |
Unlimited |
Max. number of files or subdirectories in a single directory |
1 billion |
File system name |
Must be globally unique. It cannot be the same as the name of any existing general purpose file system, including one created by the current user or any other user. And it cannot be changed after the file system is created. |
File system deletion |
If a general purpose file system is deleted, you can only create a general purpose file system with the same name as the deleted one 30 minutes after that file system has been deleted. |
Client OS |
|
Changing root directory permissions |
Not supported |
Restrictions in the CCE and CCI scenarios |
|
Lifecycle management |
A maximum of 20 lifecycle rules can be configured for a file system. |
File locking with Flock |
Not supported |

100 |
Max. path length (unit: byte) |
1,024 |
Max. soft link length (unit: byte) |
1,024 |
