The tuning guidelines presented in this chapter will have the most benefit on the following recommended configuration:
Storage requirements are higher than for traditional workloads
To maximize your performance, we recommend a fast DASD subsystem (for example, IBM Shark), running with a high cache read/write hit rate.
For high bandwidth applications, we recommend at least a 1 Gb Ethernet connection. If your applications have extremely high bandwidth requirements, you may need additional Ethernet connections.
For applications that make heavy use of cryptography, we recommend the zSeries or S/390 cryptographic hardware and the Integrated Cryptographic Service Facility. For more information, refer to the zSeries and S/390 Cryptography Web site.
