Disk drive emulations
When VMAX arrays are configured to mainframe hosts, the data recording format is
Extended CKD (ECKD). The supported CKD emulations are 3380 and 3390.
Cascading configurations
Cascading configurations greatly enhance FICON connectivity between local and
remote sites by using switch-to-switch extensions of the CPU to the FICON network.
These cascaded switches communicate over long distances using a small number of
high-speed lines called interswitch links (ISLs). A maximum of two switches may be
connected together within a path between the CPU and the VMAX array.
Use of the same switch vendors is required for a cascaded configuration. To support
cascading, each switch vendor requires specific models, hardware features, software
features, configuration settings, and restrictions. Specific IBM CPU models, operating
system release levels, host hardware, and HYPERMAX levels are also required.
