“High reliability, uptime and availability are imperative in today’s ?always-on Digital networks. For the 12th straight year, IBM’s Z and Power Systems achieved the highest server; server operating system reliability, and server application availability rankings, along with Lenovo’s ThinkSystem servers which delivered the best uptime among all Intel x 86 servers for the last seven consecutive years. Those are the results of ITIC’s latest Global Server Hardware and Server OS Reliability survey, which polled 1,200 global enterprises from January through March 2020.
ITIC’s latest survey data finds that the elite IBM z14 and z15servers are in a class of their own, averaging just 0.62 seconds of monthly/7.44 seconds of annual unplanned per server downtime due to bugs in the underlying hardware. This is consistent with very high availability and fault tolerance of ?six nines? – 99.9999% and greater. The IBM Z family – the ?Z? stands for zero downtime – consistently outperforms all competitors in every reliability category and delivers the lowest total cost of ownership (TCO) and fastest return on investment (ROI). Additionally, IBM’s Power Systems, Lenovo ThinkSystem, Hewlett-Packard Enterprise (HPE) and Huawei KunLun, respectively, also scored high reliability marks, recording up to 28xs more uptime and availability than the least dependable unbranded ?White box? servers. The superior uptime of the above top ranked mission critical hardware platforms makes them up to 34xs more economical and cost effective than the least stable White box servers.”
