a. PTFs might be required for toleration support or use of z13s functions and features.
b. Hardware limit of 6 CP and 2zIIP:1CP ratio.
c. With SMT, 40 threads.
d. zAware V2.0, Linux Guest support.
e. 4 TB of real storage is supported with PTF for APAR OA47439.
f. PTF support required and with RSM enabled web delivery.
g. Packed decimal conversion support.
h. PTF support required.
i. On z13s servers, the CHPID statement of HiperSockets devices requires the keyword VCHID,
so the z13s IOCP definitions need to be migrated to support the HiperSockets definitions
(CHPID type IQD). VCHID specifies the virtual channel identification number associated with
the channel path. Valid range is 7E0 - 7FF. VCHID is not valid on z Systems before z13s
servers.
j. For guest exploitation only.
k. Dynamic I/O support only.
