IBM z Systems Enterprise; IBM Power Systems Servers Most Reliable for Ninth Straight Year; Lenovo x86 Servers Deliver Highest Uptime/Availability among all Intel x86-based Systems
For the ninth year in a row, corporate enterprise users said IBM’s z Systems Enterprise mainframe class server achieved near flawless reliability, recording less than 10 seconds of unplanned per server downtime each month. Among mainstream servers, IBM Power Systems devices and the Lenovo x86 platform delivered the highest levels of reliability/uptime among 14 server hardware and 11 different server hardware virtualization platforms.
Those are the results of the ITIC 2017 Global Server Hardware and Server OS Reliability survey which polled 750 organizations worldwide during April/May 2017.
Among the top survey findings:
- IBM z Systems Enterprise mainframe class systems, had the lowest incident – 0% — of > 4 hours of per server/per annum downtime of any hardware platform. Specifically, IBM z Systems mainframe class servers exhibit true mainframe fault tolerance experiencing just 0.96 minutes of of unplanned per server annual downtime. That equates to 8 seconds per month or “blink and you miss it,” 2 seconds of unplanned weekly downtime. This is an improvement over the 1.12 minutes of per server/per annum downtime the z Systems servers recorded in ITIC’s 2016 – 2017 Reliability poll nine months ago.
- Among mainstream hardware platforms, IBM Power Systems and Lenovo System x running Linux have least amount of unplanned downtime 2.5 and 2.8 minutes per server/per year of any mainstream Linux server platforms.
- 88% of IBM Power Systems and 87% of Lenovo System x users running RHEL, SuSE or Ubuntu Linux experience fewer than one unplanned outage per server, per year.
- Tenly two percent of IBM and Lenovo servers recorded >4 hours of unplanned per server/per annum downtime; followed by six percent of HPE servers; eight percent of Dell servers and 10% of Oracle servers.
- IBM and Lenovo hardware and the Linux operating system distributions were either first or second in every reliability category, including virtualization and security.
- Lenovo x86 servers achieved the highest reliability ratings among all competing x86 platforms
- Lenovo Takes Top Marks for Technical Service and Support: Lenovo tech support the best followed by Cisco and IBM
- Some 66% of survey respondents said aged hardware (3 ½+ years old) had a negative impact on server uptime and reliability vs. 21% that said it has not impacted reliability/uptime. This is 22% increase from the 44% who said outmoded hardware negatively impacted uptime in 2014
- Reliability continues to decline for the fifth year in a row on the HP ProLiant and Oracle’s SPARC & x86 hardware and Solaris OS. Reliability on the Oracle platforms declined slightly mainly due to aging. Many Oracle hardware customers are eschewing upgrades, opting instead to migrate to rival platforms.
- Some 16% of Oracle customers rated service & support as Poor or Unsatisfactory. Dissatisfaction with Oracle licensing and pricing policies remains consistently high for the last three years.
- Only 1% of Cisco, 1% of Dell, 1% of IBM and Lenovo, 3% of HP, 3% of Fujitsu and 4% of Toshiba users gave those vendors “Poor” or “Unsatisfactory” customer support ratings.
