Maximum number
For details about the maximum number of adapters that are supported, see PCIe adapter
placement rules and slot priorities (http://www.ibm.com/support/knowledgecenter/POWER8/
p8eab/p8eab_mtm_pciplacement.htm) and select the system you are working on.
Attributes provided
High throughput compression that saves storage and I/O bandwidth with little or no overhead
CPU offload and CAPI interface with negligible software load frees up CPU cores for higher
value computation or licensed software
Lower power consumption by offloading the CPU intensive compression to an FPGA
