Hypervisor I/O Virtualization – Provided by
• “Virtualization” software or firmware • Hypervisor (VMware)
• Divides real computing into logical computers or LPARs • I/O owning LPAR (PowerVM, Xen)
• Referred to as “PR/SM” on System z • Direct hardware virtualization (z)

Blue = System z specific terms
© 2012 IBM CorporationSystem z Terminology – Cores
System z - Core Personality
• For the IT industry…
Central Processor (CP)
– Chip = socket
• Runs z/OS operating system (and others)
• For System z… zSeries Application Assist Processor (zAAP)
– Core = processor = engine = CPU • Offloads JAVA from z/OS processors
zSeries Integrated Information Processor (zIIP)
• Offloads DB2 from z/OS processors
Internal Coupling Facility (ICF)
• z/OS clustering processor
Integrated Facility for Linux (IFL)
• Runs Linux or z/VM only
System Assist Processor (SAP)
• Manages/offloads shared I/O environment
Spares
• Dynamically replaces any failing core

System z is designed to deliver application availability up to 99.999%,
which equates to approximately five minutes of downtime in a year
on average.
The cost per user over a 5 year period for the mainframe is half of
running on distributed PC’s.
The mainframe was the first IBM server platform to announce support
for Linux and can run over a thousand virtual Linux images on one
frame the size of a refrigerator. Linux on the mainframe has already
grown to approximately 20% of mainframe capacity shipped.
80% of world’s corporate data resides or originates on mainframes.
Since 2000, the mainframe has captured 17 points of market share in
the high-end server category according to IDC.
2/3 of business transactions for U.S. retail banks run directly on
mainframes.

© 2012 IBM CorporationSystem z No Frills, Just Facts (2 of 2)
There are more than 1300 ISVs running on System z today. More than 275 ISVs
sell over 800 Linux applications on System z.
Mainframes act as a centralized repository of encryption keys to facilitate
security management. Each Crypto Express 2 feature can handle up to 6,000
Secure Sockets Layer handshakes per second, which equates to up to 48,000
SSL handshakes per second with eight of these in a z9 box.
66% of mainframe capacity shipped today comprises of "new workloads"
including Linux, WebSphere, SAP and other leading enterprise business
applications.
The IBM mainframe experienced 28% growth in capacity year over year in Q4
2005, the largest revenue gain for the mainframe since it came roaring back in Q4
1998, with the largest shipment of capacity in history.
25 of the top 25 worldwide banks, 23 of the top 25 U.S. retailers, and 9 of the top
10 global life/health insurance providers run on System z.
64% of Fortune 500 (U.S.), 45% of Fortune 1000 (U.S.), and 71% of Fortune
Global 500 are System z clients.
