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.

Today’s applications live across a complex, multidomain world—from enterprise data centers and private and public clouds, to campus, branch, and edge locations. Cisco HyperFlex systems with Intel® Xeon® Scalable processors make it easy to modernize and simplify deployments and operations. Engineered with Cisco Unified Computing System (Cisco UCS®) technology, and managed through the Cisco Intersight cloud-operations platform, Cisco HyperFlex systems deliver flexible scale-out infrastructure that can rapidly adapt to changing business demands.

We have created Cisco HyperFlex Express to simplify the onboarding process, especially for new customers, to get products on site quickly. Cisco HyperFlex Express delivers “high-velocity transactions” with simplified ordering and fast delivery. With HyperFlex Express, we have taken our most popular Cisco HyperFlex node configurations, added a few simple and important options, priced them attractively to deliver optimal value, and reduced transaction times to help keep your plans on track.

Simplicity you can build on

With hybrid Small-Form-Factor (SFF) and Large-Form-Factor (LFF), or all-flash-memory storage configurations and cloud-based management, Cisco HyperFlex Express HX240c M6 systems 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 applications and your business (Figure 1). Based on Intel Xeon Scalable processors, these servers have faster processors, more cores, and faster and larger-capacity memory than previous-generation servers. In addition, they are ready for Intel Optane persistent memory (PMem) which can be used as both storage and system memory, increasing your virtual server configuration options and flexibility for applications.

Cisco HyperFlex Express HX240c M6 Node family

The Cisco HyperFlex Express HX240c M6 Node family delivers high disk capacity (up to 28 drives) in a 2-socket, 2RU package ideal for storage-intensive applications. Physically, the system is delivered as a cluster of three or more Cisco HyperFlex Express HX240c M6 Nodes, HX240c M6 All NVMe Nodes, HX240c M6 All Flash Nodes, or HX240c M6 LFF Nodes. The nodes are integrated into a single system by a pair of Cisco UCS 6300 or 6400 series fabric interconnects, creating clusters that deliver the performance and storage capacity needed by workloads. All nodes use Intel Xeon Scalable processors and next-generation DDR4 memory and offer 12-Gbps SAS throughput.

Hybrid configurations

The HX240c M6 Node family can be deployed with various Cisco UCS B-series blade servers and C-series rack servers to create a hybrid cluster. Incorporating Intel Xeon Scalable processors, these Cisco HyperFlex HX-series nodes offer an improved price-to-performance ratio that ranks them among the best values in the industry. Cloud-based management makes it easy for you to scale your cluster to support more workloads and deliver the performance, bandwidth, and low latency that your users and applications need.
