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.
