IBM Offers Rock Solid Reliability, Best in Class Server Performance

2013, Laura's Insights ITIC Blog / By

Big Blue Hardware is Rock Solid

IBM hardware retains its status as being best in class in terms of reliability, stability and performance and customer satisfaction. IBM’s System z mainframes recorded the least amount of downtime of any hardware platform. In the server hardware category systems with relatively small market shares, including Stratus Technologies ftServer 6300 and 4500 series and Fujitsu’s Primequest and Primergy Servers continue to score very high reliability.

Stratus Technologies of Maynard, MA offers Intel Xeon-based systems with mainframe-like fault tolerance and reliability with 99.999 % reliability. The Fujitsu Primergy and Fujitsu SPARC systems similarly deliver a high level of reliability and fault tolerance with 48% of reporting 99.999% or just over five minutes of per server/ per annum downtime due to unplanned outages.

The length and severity of Tier 1, Tier 2 and Tier 3 unplanned outages and the patching actions related to each correspond to specific line item capital expenditure (CAPEX) and operational expenditure (OPEX) costs for the business. Reliability, measured by downtime, can positively or negatively impact TCO and accelerate or delay ROI. …

Human Error, IT Staff Shortages and Aging Hardware Undercut Reliability

2013, Laura's Insights ITIC Blog / By

To reiterate, ITIC’s fifth annual reliability survey results indicate that the inherent reliability and uptime of nearly all of the 14 major server hardware and 18 server operating system distributions continues to improve. But at the same time, user error is becoming more of a factor undercutting overall reliability.

This is based on technical advances in the underlying processor technology from companies like Intel Corp. and Advanced Micro Devices, memory and disk technology, as well as improvements to the core server hardware and server OSs that improve performance, scalability, security and the ability to support heavier workloads.

As organizations strive to accomplish more with fewer resources, IT departments must rely even more heavily on their vendors to deliver more reliable servers and server OS platforms and top notch technical support in the form of regular patches and documentation. …
