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.

Cisco and Nutanix have partnered to introduce the IT industry’s most complete hyperconverged solution by integrating and validating Cisco® servers, storage, networking, and SaaS operations with the Nutanix hybrid multicloud platform. Cisco Compute Hyperconverged with Nutanix is built, managed, and supported holistically to deliver a more seamless experience, foster innovation, and accelerate customers’ hybrid-cloud journeys. Modern workloads require modern flexibility. Traditional hyperconverged solutions require scaling compute and storage together. When you need to scale compute capacity without adding storage, Cisco Compute-Only (CO) nodes provide that critical capability—empowering you to design clusters that match your exact requirements.

Product overview

The Cisco Compute X-Series System simplifies your data center, adapting to the unpredictable needs of modern applications while also providing for traditional scale-out and enterprise workloads. It reduces the number of server types to maintain, helping to improve operational efficiency and agility as it helps reduce complexity. Powered by the Cisco Intersight® cloud-operations platform, it shifts your focus from administrative details to business outcomes—with hybrid-cloud infrastructure that is assembled from the cloud, shaped to your workloads, and continuously optimized.

Cisco Compute-Only X215c M8 All NVMe Node

Expanding Cisco Compute Hyperconverged node cluster with Cisco Compute-Only node

The Cisco Compute-Only node solution enables you to expand the compute resources of Cisco hyperconverged clusters running Nutanix by adding Cisco UCS®-certified servers without additional storage. These storage-less, compute-only (CO) servers certified by Cisco integrate seamlessly into your existing or new hyperconverged Nutanix cluster, allowing organizations to efficiently support compute-intensive applications by scaling processing resources independently of storage infrastructure.

Key benefits

     Cost-effective scaling for compute-heavy workloads

     Flexibility in cluster design

Cisco Compute-Only node connected to Everpure Flash Array (FlashStack with Nutanix)

Everpure FlashArray//X and FlashArray//XL deliver mission-critical performance with the efficiency and resiliency that is missing from legacy arrays. FlashArray //X and FlashArray//XL pack more IOPS, ultra- consistent latency, and greater scale into a smaller footprint. Nondisruptive upgrades, always-on availability, and built-in data protection help to ensure that workloads are always running while reducing risk. FlashArray//XL is designed to provide the highest performance density with a level of operational and management simplicity. FlashArray//C delivers a balanced all-flash storage solution optimized for file services and general-purpose workloads. With predictable performance, streamlined operations, and built-in cyber resiliency, it keeps applications consistently secure and positions organizations to outperform capacity-optimized, all-flash, and hybrid storage alternative.

Nutanix Cloud Platform (NCP) consolidates computing, storage, and networking into a unified pool. It uses Nutanix Acropolis Operating System (AOS) for storage, Nutanix (Acropolis Hypervisor (AHV) for virtualization, and Nutanix Prism Central for centralized management across environments.

The Cisco Compute-Only node with Nutanix Cloud Platform (NCP) and Everpure FlashArray solution delivers a disaggregated infrastructure architecture that enables independent scaling of compute and storage resources. This solution combines industry-standard Cisco Compute-Only node servers running Nutanix AHV and AOS connected to external Everpure FlashArray. This architecture leverages Everpure software-defined storage environment optimized for enterprise workloads. The FlashStack solution with Nutanix integration provides organizations with the agility to adapt infrastructure resources dynamically while maintaining enterprise-level reliability and performance.

Key benefits

     Independent scalability: scale compute and storage resources separately based on workload demands

     Enterprise-grade protection: built-in data protection and disaster recovery capabilities

     Hybrid-cloud readiness: seamlessly extend operations across on-premises and cloud environments

     Investment protection: use Nutanix Cloud Platform with existing external storage

Benefits

Since we first delivered the Cisco Unified Computing System (Cisco UCS) in 2009, our goal has been to simplify the data center. We pulled management out of servers and into the network. We simplified multiple networks into a single unified fabric. And we eliminated network layers in favor of a flat topology wrapped into a single unified system. With the Cisco Compute Hyperconverged X-Series System, we take that simplicity to the next level:

     Simplified operations with a solution that combines the operational simplicity of hyperconverged software with the efficiency and flexibility of a modular system

     Increased agility and response to the dynamic needs of your business with a solution that is inherently easy to scale and includes support for future generations of processors, storage, accelerators, networking technologies, and SaaS innovations

     Improved sustainability with a solution that is engineered to be more energy efficient and can be easily upgraded and reused, lowering the consumption of power and raw materials when compared to traditional rack servers
