File Protocol |
SMB/AFP/NFS/FTP/WebDAV |
Maximum Concurrent SMB/AFP/FTP Connections |
200 |

Notes |
The testing standard was based on the maximum number of concurrent connections supported by this model. During the testing, 25% of the connections were used to transfer files concurrently. The transfer process guaranteed that the connections were not interrupted; the minimum transfer speed was not guaranteed. |
