IBM Systems Magazine, Mainframe Edition - March/April 2013 - 30

Consolidation and Virtualization
With zEnterprise, IT can scale to address
increasing business requirements through
dynamic hardware provisioning and
sharing of system resources. Virtual server
CPU, memory and I/O resources can be
optimized to align with business priorities,
while the system’s Capacity Upgrade
on Demand capabilities enable users to
quickly and easily add CPU capacity on
the existing footprint.
This flexibility is bolstered by the
mainframe’s capability to quickly and
easily add virtual machines (VMs) to
enhance computing capacity as needed
for extremely heavy demand periods.
The Bathwick Group’s November 2011
study, “Building a Foundation for a
High-Performance, Low-Cost Private
Cloud,” reported on the significant cost
benefits derived from higher-density
VMs made possible per processor core
by the zEnterprise platform. The savings
on software licensing fees, which often
are charged per processor core, can be
as high as 90 percent when consolidating
onto an IBM Enterprise Linux* server,
the report states.
As demonstrated in IBM internal
testing as well as observations from
mainframe clients, best practices for x86
environments limit the number of VMs
per core to approximately three, with a
correspondingly low limit of 50 percent
server utilization. Compare this with
zEnterprise, which has a target utilization
of more than 70 percent—and can run
at more than 95 percent utilization when
running on z/OS*—and the numbers of
VMs typically exceed 30 per processor
core. The math reveals that just one
zEnterprise mainframe can support
more than 300 virtual Linux servers. The savings are
considerable for even small deployments, but it’s in larger
environments where the economics of zEnterprise become
truly compelling.
Protecting Sensitive Data
Practically any discussion of cloud computing quickly turns to
security. That’s traditionally an area where mainframes shine,
and the zEnterprise System is no different. Featuring the

capability to do direct-to-disk backups or
tape backup, the option for continuous
data protection strategies, zEnterprise
offers layered protection for critical data.
And zEnterprise servers have earned the
Common Criteria Evaluation Assurance
Level 5 (EAL5)—the highest security
rating classification awarded to any
commercially available server.
This demonstrated capability should
give IT administrators the confidence
to deploy sensitive data or run missioncritical applications on their zEnterprise
technology-based cloud using securityrich partitions designed to keep each
application’s data distinct.

Faster Application Development
For application development and testing
activities where databases must be rapidly
provisioned and deprovisioned, the
zEnterprise platform shines as well.
IBM testing has shown dramatic
reductions in the time required for these
activities. One production environment
requiring three days to replicate a 300
GB master image 16 times to distributed
servers was able to do the same job
in only one hour using a virtualized
zEnterprise environment.
Superior Analytics Performance
Analytics, too, is an area of strength.
The latest mainframe, the zEnterprise
EC12 (zEC12), is designed to deliver
up to 30 percent better analytics
performance over its predecessor, which
was already among the leading analytics
performers.
The zEC12 is complemented
by IBM’s strong analytics portfolio,
which helps organizations make
sense of the massive volumes, variety and velocity of data
flooding enterprises. This portfolio includes the IBM DB2*
Analytics Accelerator V3, an analytics platform designed
for complex queries. And the IBM SmartCloud Foundation
framework leverages analytics to provide deep insights on
the infrastructure capacities required to run various cloud
workloads. Meanwhile, IBM SmartCloud Monitoring
software offers recommendations to help optimize capacity
planning to avoid bottlenecks.
