Receiving buffer credits by a plurality of channels of one or more host computational devices for transmitting data to a control unit

A channel of a host computational device sends a command to transfer data to a control unit included in a storage controller. The channel of the host computational device receives a number of buffer credits from the control unit for communication with the control unit, where the number of buffer cre...

Zusammenfassung:A channel of a host computational device sends a command to transfer data to a control unit included in a storage controller. The channel of the host computational device receives a number of buffer credits from the control unit for communication with the control unit, where the number of buffer credits that is received is based on the control unit monitoring a number of transfer ready operations and a number of retry operations during a monitoring period while communicating with a plurality of channels that includes the channel.
