Specialty engines are processors that can help users expand the use of the mainframe for new workloads, while helping to lower cost of ownership.
The IBM zIIP is available on all IBM zEnterprise, IBM System z10 and IBM System z9 servers. The zIIP can support many technologies, and can help implement, integrate, and optimize new workloads on System z.
The IBM System z Application Assist Processors (zAAPs), available on IBM zEnterprise, IBM System z10, IBM System z9, and IBM eServer zSeries 990 and 890 systems. The zAAP provides a strategic z/OS Java™ execution and z/OS XML parsing environment.
The Integrated Facility for Linux® (IFL) is a processor dedicated to Linux workloads. The attractively priced IFL processor allows you to purchase additional processing capacity for Linux workloads, without increasing IBM software charges for the existing System z environment. The IFL is available on all IBM zEnterprise, IBM System z10, IBM System z9 and IBM eServer zSeries servers.
System Assist Processor (SAP)
The SAP is standard on IBM System z servers and is a dedicated I/O processor to help improve efficiencies and reduce the overhead of I/O processing of every IBM System z logical partition regardless of the operating system (z/OS, z/VM, Linux, z/VSE and z/TPF). For very high I/O intensive workloads, an additional one or more SAPs can be purchased (model dependent).
