Command-line | Registry

 

This setting is only used if managed devices are configured for peer-to-peer file sharing (AllowPeerToPeer is True). It specifies the maximum allowable rate (in bytes per second) for all disk I/O activities associated with updating the peer cache and sharing files with peer managed devices. DiskMaxRate is used in conjunction with DiskAveragingTime to limit disk I/O operations. RayManageSoft Unified Endpoint Manager calculates the sum of disk reads and writes that have occurred to update the peer cache and share files with peer managed devices:

 

•Downloads from distribution servers.

•Transfers to and from peers.

•Internal copying of files to the peer cache when duplicate versions of a file are requested.

 

It does not include the very small amounts of disk I/O associated with saving the peer download file. Since disk transfers occur in blocks and not as a continuous stream, RayManageSoft Unified Endpoint Manager smooths out the variation in transfer rates, using the DiskAveragingTime and a simple exponential decay algorithm. The result is an estimate of the disk transfer rater. Transfer rates will be decreased if the estimated rate exceeds the specified DiskMaxRate and increased if they are below the specified DiskMaxRate (Transfers can creep up to the DiskMaxRate, but will drop back rapidly when the estimate rate is greater than the DiskMaxRate.). RayManageSoft Unified Endpoint Manager retrieves the value for this setting from the registry every five seconds. It is not necessary to restart RayManageSoft Unified Endpoint Manager on a managed device after changing the value of this setting.
