Standard values for the channel workload

In the case of channels with ETERNUS DX/AF or Symmetrix storage systems connected, the workload should not exceed 60%. This applies for both native operation and operation under VM2000 (see also information on the "Report group CHANNEL").

Report	Meaning
Data transfer	Number of PAM blocks transferred
IOs	Number of I/O operations per channel

Tuning measure for channel overload: reconfiguration

As a rule the load of one or more LUNs is distributed equally over the channels assigned to them. Temporary overloads (15 minutes) for application-related reasons can be tolerated. In the case of overloads lasting for a longer time, more channels must be provided for the relevant LUNs, see section "FC connection".
