ï· An new integrated radiator-based air cooling system and optional water cooling (for example, water
cooling can offer about 9% additional data center energy savings) and DC power as well as an optional
non-raised floor and overhead cabling options for both I/O and power
ï· The result is noticeably improved I/O throughput, more processing power, near 100% system
availability and bullet-proof security. IBMâs self-described intent is to âdeliver the worldâs fastest, most
scalable and secure enterprise system with the ability to integrate resources for:
ï· Operational analytics across the enterprise
ï· Trusted resilience to provide hardened security and the highest levels of availability
ï· Efficiency at scale to deliver services via a private cloud
Analysis
Enterprise demand for increased transactional and processing power, as well as greater efficiencies and
economies of scale has never been greater. This is crucial in order for enterprises to effectively support core
business applications and transactions. These criteria individually and collectively play to IBMâs zEnterprise
EC12 familyâs strength as one of the most highly reliable hardware systems currently available.
IBMâs latest zEnterprise servers and strategy are well defined and well thought-out from both the technology
and business standpoints. IBM clearly has addressed all of the major issues and potential challenges that their
enterprise customers face in transitioning to more compute intensive and demanding workloads.
The latest ITIC 2012 Global Server Hardware and Server OS Reliability Survey statistics supports IBMâs
claims of 99.999% and 99.9999% (âfive and six ninesâ) of system availability for System z solutions. The
independent Web-based survey polled over 500 organizations worldwide in August and September 2012.

The survey results showed that IBM, Stratus Technologies, Fujitsu and Hewlett-Packard servers (in that
order) were the four most reliable platforms, achieving an average 99.99% or 99.999% uptime per server, per
annum. That equates to an individual server being offline for 52 minutes (99.99%) or 5.25 minutes
(99.999%) annually.
The most recent ITIC poll also revealed that 14% of the over 500 respondent organizations require the
highest 99.999% degree of reliability in their IT and business operations. Additionally, three percent of
survey participants indicated their firms require an even more stringent âsix ninesâ (99.9999%) uptime which
translates to a mere 52 seconds of per server, per annum unplanned annual downtime. Among this latter elite
user group, 56% said they had IBM System zEnterprise servers. And in first person interviews with ITIC
analysts, the majority asserted the System zEnterprise servers delivered close to 99.9999% -- six nines of
availability.
Overall, IBMâs System z servers achieved the highest degree(s) of reliability among the one dozen
competing server hardware platforms discussed in the ITIC survey. Nearly two-thirds or 63% of respondents
indicated their firms experienced one to five minutes of unplanned downtime for 99.999% or better
reliability. Additionally, less than one-half of one percent of those polled said they had experienced
downtime of more than four hours on any of their System z servers.
Reliability and by association, security are pivotal metrics which have immediate and long lasting impact and
ramifications on overall network health and daily operations. Any service disruptions impact business
operations and end user productivity. The trickledown effect and impact is almost instantaneous. It disrupts
operations for the companyâs end users, partners, suppliers and customers, causing business to grind to a halt.
The consequences of a moderate Tier 2 outage of one-to-four hours or a severe Tier 3 outage of four hours or
more, can cause significant business losses, damage the companyâs reputation and heighten the risk of
litigation. In vertical markets such as banking, finance, healthcare, government and insurance that comprise
the core constituency of System zEnterprise customers, even a seemingly minor Tier 1 outage where the
server is unavailable to process transactions for even five, 10 or 15 minutes could be damaging or even
catastrophic. In these environments itâs not unusual for losses to amount to millions of dollars for each
minute of downtime.
Users Give System zEnterprise High Marks
ITIC 2012 Global Server Hardware and Server OS Reliability survey respondents were quite vocal in their
assessments of IBM System zEnterprise serversâ security and reliability performance.
âThe only good downtime for us is no downtime,â observed the VP of IT at a large Midwestern bank. âWhen
the server goes offline for any reason for even five minutes, our financial transactions grind to a halt. Our
knowledge workers and customers feel the impact immediately and they are not shy about vocalizing their
discontent,â the VP of IT said.

He also noted that the IBM System z servers have proven an excellent investment for his organization for
their rock solid reliability and superior security. âThey offer very high performance. We were able to reduce
our workload costs by about 12% last year while optimizing data throughput by roughly 10%,â he said.
System stability and security are both rock solid. âThe last time we had any unplanned downtime was when
someone accidentally unplugged the System z server.â
Conclusions and Recommendations
ITIC advises customers to conduct a thorough audit to determine the reliability of their current server
environments according to the number, length and severity of Tier 1, Tier 2 and Tier 3 outages and compare
them against the IBM zEnterprise EC12 family. Customers are also urged to conduct their own benchmark
tests in pilots that mirror production networks and workloads as closely as possible.
Organizations should also perform regular security audits of their entire server hardware and server OS
infrastructure to determine and eliminate vulnerabilities and compare and contrast the security of their
various platforms.
The ability to meet service-level agreements (SLAs) hinges on server reliability, uptime and manageability.
These are key indicators that enable organizations to determine which server hardware platform provides the
business with the greatest performance, reliability and processing power to address sophisticated and
demanding applications. The new IBM System zEnterprise EC12 family scores high in all of these
categories.
