System z’s Extreme Virtualization
Built into the architecture not an “add on” feature
System z
• Deploy virtual servers in seconds
• Highly granular resource sharing (<1%)
PR/SM™ • Add physical resources without taking system
down, scale out to 1000s of virtual servers
• Do more with less: More virtual servers per core,
LPAR – Up to 60 Logical partitions
Share more physical resources across servers
• Extensive virtual server life-cycle management
• Hardware-enforced isolation
z/VM – 100s of virtual servers – Shared Memory
Distributed Platforms
• Limited per-core virtual server scalability
• Physical server sprawl is needed to scale
• Operational complexity increases as virtual server
images grow
• VMWare, Xen, Virtual Iron focus only on x86, not
cross platform hardware management.

The economics of Linux on z114 for consolidation and cost reduction
Consolidate an average of 30 distributed servers or more on a single core, or
hundreds in a single footprint.
Deliver a virtual Linux server for approximately $500 per year or as little as
a $1.45 per day per virtual server (TCA)1
TCA Analysis:
Consolidate 40 Oracle server cores onto 3 Linux cores on z114
Lower acquisition costs of hardware and software vs. distributed servers
– up to 51% less than Nehalem2 in new footprint (Enterprise Linux Server (ELS)) –
– or up to 62% less when adding to existing footprint (Solution Edition for Enterprise Linux (SEEL)) –
Plus, additional savings in DR, floor space, power, cooling and labor costs
