IBM claims its new
is the highest performing, most efficient mainframe
ever and the z196 core server has something to do with that. In a July 22 press
release describing its new system offering, IBM
said the core server in the zEnterprise System - called zEnerprise 196 (z196) -
contains 96 microprocessors running at 5.2Ghz, capable of executing more than
50 billion instructions per second. From a performance standpoint, the
zEnterprise System is the most powerful IBM
system ever, IBM said.
IBM's general manager for
its System z business, Tom Rosamilia, said IBM's
new IBM microprocessor technology has new
software to optimize performance of data-heavy workloads, including up to a 60
percent improvement in data intensive and Java workloads. IBM
officials said increased levels of system performance in turn increases
software performance, which can reduce software license costs.
the new system is up to 60 percent faster than its predecessor, the System z10,
and uses about the same amount of electricity, IBM
said. More than 100,000 virtualized servers can be managed as a single system
on a fully configured cluster of zEnterprise Systems. And for customers running
Linux, a single virtualized server can be created and deployed on the zEnterprise
System for less than $1 per day.
z196 can be configured to include up to 80 specialty engines to further reduce
costs and increase performance including the System z Application Assist
Processor (zAAP) for integrating Java workloads with core business
applications, the System z Integrated Information Processor (zIIP) designed to
help free-up computing capacity and lower IT costs, and the Integrated Facility
for Linux (IFL) to optimize Linux workloads running on the mainframe, IBM
said in its press release.
IBM said energy efficiencies in the
zEnterprise engine were achieved through advances in microprocessor design,
45nm silicon technology, more efficient power conversion and distribution, as
well as advanced sensors and cooling control firmware that monitors and makes
adjustments based on environmental factors such as temperature and humidity
levels and even air density.
instance, a water cooling option is also available for the z196 that can reduce
energy use by up to 12 percent, IBM said. In
a normal data center environment, water cooling reduces the required system air
flow by more than 20 percent, while removing more than 70 percent of the system
air heat load, IBM explained in its press
release. IBM officials said this can be particularly
beneficial for data centers with hotspots, or limited power and cooling
capacity. Water cooling on the z196 is designed to connect directly to typical
data center chilled water systems and does not require an external water
the new z196 builds on the IBM System z
industry leading security features. And IBM
officials said the System z server is the only commercial system to achieve
Evaluation Assurance Level 5 security classification.
