This submenu displays the current GDT cache settings which can be changed here. The
various settings are:
&DFKH21
the GDT cache is enabled, that is, all accesses to the Host
Drives pass through the GDT cache
&DFKH2))
the GDT cache is disabled
'HOD\HG:ULWH21
Write accesses are delayed, i.e., the write-back cache algorithm
is active
'HOD\HG:ULWH2))
All write accesses are directly transmitted to the Host Drives. If
delayed-write is off and the Cache is ON, the GDT cache works
exclusively as a read cache.
Note: Best performance is achieved with
Cache ON
and
Delayed Write ON
.
