Best Rack Servers

Dell PowerEdge is Dell's server family spanning rack, tower and edge form factors, covering AI and high performance computing servers, general purpose compute, server security and systems management across virtual, physical, local and remote environments.

How thoroughly the line is now positioned around AI is the most telling thing about the current generation. Dell cites acceleration optimised PowerEdge servers as central to its position as a leader in AI infrastructure solutions, and the customer stories are about running models on premises rather than about consolidation or virtualisation, which were the arguments a decade ago.

The on premises argument is the interesting one underneath that, and Dell lets a customer make it rather than making it directly. Northwestern Medicine describes deploying AI tools on its own PowerEdge servers as easier, faster, cheaper and better than in the cloud, which for a healthcare organisation reflects data residency and predictable cost on a sustained workload rather than a general claim about cloud economics.

Systems management is where a server line is actually won or lost at scale, since the difference between one server and four hundred is entirely in provisioning, firmware, monitoring and remote hands, and Dell offers self paced virtual labs so the management tooling can be tried before purchase. ProDeploy factory configuration is offered for installation. Prices vary by configuration and are not published as a rate on the captured pages.

IBM Power is IBM's server platform built on the Power processor architecture, with the Power11 family spanning the S1112, S1122 and S1124 rack and tower systems and the E1150 and E1180 high end servers, offering up to 120 Power11 cores and 16 TB of DDR5 memory at the top of the range.

Zero planned downtime for system maintenance is the claim IBM leads with and it explains the whole platform. Power Systems servers are bought by organisations where the application cannot stop, typically core banking, insurance policy administration, retail settlement and manufacturing execution, and for those workloads the relevant comparison is not price per core against commodity hardware but the cost of an outage.

Power Cyber Vault is the more recent argument and it is a sound one. It creates prescriptive, immutable and air gapped copies of data specifically against ransomware, which matters because the failure mode of modern ransomware is that the backups are encrypted too, and an immutable copy the attacker cannot reach is the only reliable answer.

Running a distinct processor architecture is the trade this platform asks a customer to accept. It buys reliability engineering and per core performance that x86 does not match on these workloads, and it costs portability, so the customers who stay are the ones whose applications were written for it. IBM's own announcement of the platform refers to it as IBM Power Systems, and IBM publishes a Power total cost of ownership calculator rather than a rate card.
