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.

Product overview

Cisco Compute-Only C240 M8 Node family
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 compute 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’s 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 ensure workloads are always running while cutting 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 alternatives.
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 technology, which is 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: utilize 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

The Cisco Compute-Only C240 M8 Node family incorporates the Intel® Xeon® 6 processors. It improves security, performance, and efficiency while helping achieve sustainability goals with built-in accelerators such as Intel Trust Domain Extensions (TDX), Intel Data Streaming Accelerator (DSA), Intel QuickAssist Technology (QAT), Intel Advanced Matrix Extensions (AMX), and Intel In-Memory Analytics Accelerator (IAA).
Cisco Compute-Only C240 M8 Nodes can be repurposed as HCI nodes by adding a drive controller and drives. For more information, please refer to specification document Cisco Compute Hyperconverged and Compute-Only with Nutanix-240 M8 All-Flash Server or Cisco Compute Hyperconverged and Compute-Only with Nutanix-240 M8 All-NVMe E3.S Server.
These servers can be interconnected and managed in:
● Intersight Managed mode: The nodes are connected to a pair of Cisco UCS 6400 Series, a pair of Cisco UCS 6500 Series, or a pair of Cisco UCS 6600 fabric interconnects that are entirely managed from Intersight (SaaS, PVA, or CVA). All servers are connected to the same pair of fabric interconnects.
