Logical host connection specifications
Figures Figure 15 shows an example of two logical host connections. Both examples support EMIF.
With ESCON, the number of Device Addressing per channel port is limited to 1024. With FICON/
zHPF, the number increases to 16,384.
In
Figure
15:
Up to 1,024 unit addresses are supported for each CHL port (limit of the ESCON CHL port spe-
cification). When the number of devices per CHL image is limited to a maximum of 1,024, 16
CU images can be assigned per CHL image. If one CU has 256 devices, the maximum number
of CUs per CHL image is limited to 4.
Up to 16,384 DEVs (all address ranges of the storage system) from one system are supported for
each CHL port. This requires that system generation is divided every 1,024 DEVs (4 CUs).
