Documentation
Definition
Counter is derived from @@IO_BUSY ( see also in SQL Server BOL). The @@IO_BUSY counter shows the time since SQL Server was started that the sqlservr.exe was busy doing I/O operations. SAP normalized this value by considering @@IDLE and @@CPU_BUSY, and calculating on a per second basis.
The value range of this counter is between 0 and the number of processors on the database server.
If the value of the counter is consistently close to the number of processors, an i/o bottleneck may exist.
If the i/o is completely busy with other processes than sqlserver.exe you will not see it here in this busy counter.
