Buffalo Surveillance Server 136
Maintain Client/Vault Connection
Vault connection sharing determines how many files are sent from the source Vault to the
destination Vault in a single connection. The higher the number of files or bytes transferred, the
longer the connection between the source and destination Vault will be maintained. Access to
a particular Vault resource (such as one drive of a multi-drive storage device) used by a process
on one client will be restricted and inaccessible to other clients in the network for the duration
of the connection.
To understand how this setting can affect a configuration, imagine an environment where a
single Vault with a single tape drive is used to service several Buffalo Surveillance Server
clients. When a client is configured with connection sharing set to 250 files, and several other
clients are configured to start jobs at the same time, no client can connect until the first client
is finished. Each client's connection to the server will lock out all other connections; all other
clients will have to wait before processing files.
To set the connection sharing value, enter a value number in the Maintain Client/Vault
Connection for text box.
Click the Files radio button or Bytes radio button depending on which you prefer. If you click
Files, connection sharing will proceed based on the number of files transmitted; if you click
bytes, based on the number of bytes.
Throttle
Throttling controls the speed at which files are sent to the Vault. Lower numbers reduce the
bandwidth. Throttle values range from 1% to 100% of total available bandwidth.
The Buffalo Surveillance Server is designed to operate at the maximum performance of its host
computer, the network environment, and the storage resources available. Sometimes, during
normal working hours, running a job at peak performance will interfere with other network
operations.
To adjust throttling, click the Throttle pull-down menu, and select the percentage of
maximum performance at which you want to operate the client on its host computer.
