Compatibility Matrix

SMB Support

FluidFS version 5 supports SMB1, SMB2, SMB2.1, and SMB3 protocols. Note that SMB3.02 clients (such as

Windows 8.1 and Windows Server 2012R2) are negotiated to SMB3.

NOTE:

• Lower-than-maximum SMB level connections are also supported.

• Setting ACL from Linux SMB clients is not supported.

Supported SMB Configurations

Each appliance can support a certain number of concurrent (active) SMB connections, even if one of the

controllers is not available. Table 10. Supported SMB Configurations lists the supported SMB

configurations.

Table 10. Supported SMB Configurations

Feature Maximum Value

SMB share name 80 bytes

SMB shares 1024 per volume / 1024 per system

Concurrent connections 10,000 per 24-GB appliance /

30,000 per 48-GB FS8600 appliance

Concurrent active connections 5000 per appliance

Large MTU (up to 256 KB) connections 50 per 24-GB controller /

Unlimited per 48-GB FS8600 controller

Maximum file size for branch cache hash

calculations

256 MB

Share names are kept as UTF-8 characters, which might, depending on the character set used, consume

multiple bytes. Therefore, the actual maximum length depends on the character set used.
