About concurrent access
Access Appliance provides support for multi-protocol file sharing where the same file system can be exported to both Windows and UNIX users using the Common Internet File System (CIFS), Network File System (NFS), and Simple Storage Service (S3) protocols. The result is an efficient use of storage by sharing a single data set across multiple application platforms.
Note:
When a share is exported over both NFS and CIFS protocols, the applications running on the NFS and CIFS clients may attempt to concurrently read or write the same file. This may lead to unexpected results, such as reading stale data, since the locking models used by these protocols are different. For this reason, Access Appliance warns you when the share export is requested over NFS or CIFS and the same share has already been exported for write access over CIFS or NFS.
The following sections describe concurrent access with multiple protocols.
