IBM Hyperconverged System – Product Brief

Last updated August 27th, 2019 for updates to EvaluScale table. Concise 5-page review of IBM Hyperconverged System including highlights, usage, overview and Eval(u)Scale product review table.

The IBM Hyperconverged Systems are hyperconverged infrastructure (HCI) appliances that combine the Nutanix Enterprise Cloud Platform software with IBM hardware, featuring the IBM POWER processors. The Acropolis operating system runs in the Controller Virtual Machine (CVM) on Nutanix’s AHV hypervisor in each node. AHV is the only hypervisor platform supported.

Each scale-out cluster is comprised of a minimum of three nodes and has no specified maximum. Nutanix appliances have multiple- node configurations with one, two or four nodes per chassis. Here, the IBM Hyperconverged Systems are different, at least with this first release, with each appliance model supporting a single-server node. Currently, IBM offers two all-flash models, with these resource configurations:

CS821 – 1U, S821LC Server, dual 10-core POWER8 processors, 8 threads per core, 128 – 256GB memory, 4 x SSDs (1.92 to 7.68TB raw)

CS822 – 2U, S822LC Server, dual 11-core POWER8 processors, 8 threads per core, 256 – 512GB memory, 8 x SSDs (3.84 to 15.36TB raw)

Prism is the control platform for IBM Hyperconverged Systems clusters that provides management of services, policies and analytics, plus monitoring. Prism also manages interfaces that are supported by the Nutanix environment. The Prism service runs on every CVM, with one node elected Prism Leader, handling HTTP requests.
