SMB Configuration

The SMB service provides access to filesystems using the SMB protocol. The supported SMB versions are: SMB 1, SMB 2.0, SMB 2.1, and SMB 3.0. To share filesystems over SMB, configure the filesystem as described in Filesystem Properties. The following tables show the supported and unsupported features for SMB 3.0 and SMB 2.1.

It is strongly advised to upgrade clients from SMB 1 to at least SMB 2.0 because SMB 1 has known security and performance issues that are resolved in later SMB versions.

Table 87  SMB 3.0 Supported and Unsupported Features

SUPPORTED FEATURES UNSUPPORTED FEATURES Transparent failover (Continuously Available shares) Encryption Multichannel SMB over Remote Direct Memory Access (RDMA) Volume Shadow Copy Service (VSS) for SMB filesystems Directory leasing

Table 88  SMB 2.1 Supported and Unsupported Features

SUPPORTED FEATURES UNSUPPORTED FEATURES Lease Branch cache Multi-protocol negotiate request Resilient handles Individual write-through operations Multi-credit operations

Local accounts and user IDs are mapped to Windows user IDs. Note that the guest account is a special, read-only account and cannot be configured for read/write in the appliance.
