Intel AS/400 RISC Server, 170 Servers, 7xx Servers manual Additional Information

y Supported number of 4764 Cryptographic Coprocessors:

Table 8.8

	server models	Maximum per server	Maximum per partition
IBM System i5	570 8/12/16W, 595	32	8
IBM System i5	520, 550, 570 2/4W	8	8

y Applications requiring a FIPS 140-2 Level 4 certified, tamper resistant module for storing cryptographic keys should use the IBM 4764 Cryptographic Coprocessor.

y Cryptographic functions demand a lot of a system CPU, but the performance does scale well when

you add a CPU to your system. If your CPU handles a large number of cryptographic requests, offloading them to an IBM 4764 Cryptographic Coprocessor might be more beneficial then adding a new CPU.
