Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Rich digital experiences need always-on, local, high-performance computing that is close to users. Retail, finance, education, healthcare, transportation, and manufacturing organizations, and remote and branch offices in general, are all pushing computing to the network edge. Cisco HyperFlex HX225c Edge M6 Nodes bring the robust feature set of Cisco HyperFlex systems to your edge environments with high-capacity storage and cloud management in a small footprint.

Simplicity for the edge

As enterprise applications migrated to centralized data centers and the cloud, the internet edge moved closer to user devices and organizational touchpoints such as remote and branch offices. Cisco HyperFlex HX225c Edge M6 Nodes are deployed as a preintegrated cluster with a unified pool of resources that you can quickly provision, adapt, scale, and manage to efficiently power your remote-office and branch-office (ROBO) locations. Physically, the solutions are deployed as sets of two, three, or four edge-specific nodes that use Cisco® or third-party Gigabit or 10 Gigabit Ethernet switches, offering the utmost in flexibility for deployment in remote and branch-office environments (Figure 1). All nodes use AMD EPYC CPUs and next-generation DDR4 memory.

Cisco HyperFlex Edge delivers a preintegrated, compact cluster to remote-office and branch-office locations

Cisco HyperFlex HX225c Edge M6 Nodes

Cisco HyperFlex HX225c Edge M6 Nodes bring high storage capacity to the network edge. These nodes are available with hybrid and all-flash storage in a one-Rack-Unit (1RU) chassis. With the same easy deployment and management as all Cisco HyperFlex Edge systems, these platforms bring greater storage capacity to edge locations and small or medium-size businesses. The solutions are managed by the Cisco Intersight® cloud-operations platform, delivering consistent policy-based enforcement, powering growing requirements in branch offices and remote sites, and enabling new IoT and intelligent services at the network edge.
