- The IBM Z and IBM Power Systems continue to dominate, delivering the best server reliability, uptime and security for the 14th straight year.
- Lenovo’s ThinkSystem servers provide the top reliability and security among all x86 server distributions for nearly nine straight years.
- Huawei KunLun, Hewlett-Packard Enterprise (HPE) Superdome mission critical servers also register high reliability and security rankings challenging the leaders. Cisco continues to up its game with robust network edge reliability and security.
- IBM Z and IBM Power Systems deliver over 40x more uptime than least efficient “White box” platforms and 60x lower Total Cost of Ownership (TCO). The Lenovo ThinkSystem, Huawei KunLun and HPE Superdome (in that order) delivered the highest reliability among x86 platforms.
- Over three-quarters of businesses – 78% – cite security as the top cause of unplanned downtime and 64% said human error causes unplanned outages.
Mission critical server and server OS distributions from IBM, Lenovo, Hewlett-Packard Enterprise (HPE), Huawei and Cisco continue to deliver the highest levels of inherent reliability and availability among 18 different server platforms despite a continuing spike in security hacks, increasing ecosystem complexities and ongoing supply chain challenges.
For the 14th consecutive year, the IBM Z, the LinuxONE III and the IBM Power Systems remained the preeminent server platforms posting the best across-the-board reliability ratings among 18 mainstream distributions. Some 96% of IBM Z mainframes and LinuxONE III server customers recorded seven nines (99.99999%) of true fault tolerant reliability and availability. The IBM Z, and LinuxONE III recorded a near-imperceptible 0.0043 minutes of per server unplanned monthly outages or just 3.15 seconds of unplanned per server downtime annually (See Table 1). This was followed by 93% of IBM Power Systems clients said the IBM systems achieved five and six nines of system reliability and availability (See Exhibit 1). The IBM Power8, Power9 and Power10 servers posted just one (1) minute each of unplanned per server monthly downtime.
The Lenovo ThinkSystem servers followed closely and posted the highest levels of reliability among all x86 hardware distributions for the eighth consecutive year. A 92% majority of Lenovo servers attained five and six nines of reliability, posting just over one minute – 1.10 – of unplanned per server monthly downtime. The Huawei KunLun and Fusion servers, the HPE Superdome and the Cisco UCS hardware (in that order), rounded out the top five most reliable server platforms.
Those are the results of the ITIC 2022 Global Server Hardware, Server OS Reliability independent Web-based survey. It polled 1,550 corporations across 30 vertical market segments worldwide on the reliability, performance and security of the leading mainstream on-premises and cloud-based servers from July through mid-November 2022. In order to maintain objectivity, ITIC accepted no vendor sponsorship.
The increased server and server operating system uptime and availability enabled the IBM, Lenovo, Huawei, HPE and Cisco servers (in that order) to deliver, the most economical Total Cost of Ownership (TCO) among all mainstream distributions in datacenters, at the network edge and in hybrid cloud environments.
The Lenovo ThinkSystem servers likewise improved their uptime and availability recording the best reliability among all x86 servers – a scant 1.10 minutes of per server unplanned monthly outages. The Huawei KunLun and Fusion platforms also improved uptimes with 1.27 minutes each of unplanned per server outage, along with the HPE Superdome platform which averaged 1.44 minutes of unanticipated per server downtime. Cisco’s UCS servers also hung tough. Cisco servers frequently are installed at the network edge/perimeter, which is often the first line of attack. The Cisco UCS servers registered two (2) minutes of monthly unplanned per server downtime.
The top server reliability vendors – led by IBM, Lenovo, HPE and Huawei – also delivered the strongest server security, experiencing the fewest number of successful data breaches and the least amount of downtime due to security-related incidents.
