Cisco’s entered the Hyperconverged Infrastructure (HCI) Appliance market in March 2016 with their HyperFlex line, using the company’s well-known UCS servers running software from startup SpringPath (which Cisco acquired in 2017). HyperFlex clusters are comprised of at least three hyperconverged nodes and as many as sixteen in hybrid or all-flash configurations (but not mixed in the same cluster). Each cluster can support up to sixteen UCS Server nodes as well, for a total of 32 nodes.
The HX220c and HXAF220c are 1U, single-node appliances that support up to 6 HDDs or SSDs in hybrid and all-flash configurations, respectively. The HX220c is also available in an “Edge” configuration with a single CPU, three drives and a lower price point. The HX240c and HXAF240c are 2U, single-node appliances with up to 23 HDDs or 23 SSDs in hybrid and all-flash configurations. These 1U and 2U nodes are available with the M4 or M5 server platforms, each with multi-core, dual-CPU architectures and a wide range of configurations. HyperFlex HX Data Platform software runs as a VM on ESXi hypervisors only, and doesn’t yet provide native support for containers.
