Cisco Compute Hyperconverged with vSAN
VMware vSAN Express Storage Architecture (ESA) is a software-defined storage solution that runs natively as part of an ESXi hypervisor. It aggregates local storage from multiple hosts to create a shared storage pool for virtual machines that can then be accessed by all hosts in the vSAN cluster.
Cisco Compute Hyperconverged with vSAN is a purpose-built platform that unifies compute, storage, and networking into a single, software-defined infrastructure. Cisco and VMware by Broadcom have partnered to deliver a robust, scalable, and high-performance hyperconverged infrastructure (HCI) solution for modern workloads.
Cisco Compute Hyperconverged with vSAN HCIVS225C M8 All-NVMe Server
VMware vSAN Express Storage Architecture (ESA) is a next-generation hyperconverged infrastructure (HCI) architecture designed to deliver exceptional performance, scalability, and resilience. vSAN ESA is optimized for high-performance NVMe-based storage and modern server platforms, offering a simplified, flash-optimized data path that enables faster I/O, improved efficiency, and lower latency. By decoupling performance from capacity, vSAN ESA supports mission-critical workloads with enhanced data services and streamlined operations—making it ideal for modern enterprise environments. vSAN ReadyNodes are pre-configured, tested, and jointly certified by Broadcom and Cisco to deliver enterprise-grade storage performance and reliability for IT customers. When deployed on Cisco UCS® servers qualified as vSAN ReadyNodes, customers can confidently build a robust hyperconverged infrastructure stack that maximizes hardware utilization, simplifies operations, and scales linearly with business growth.
Cisco Compute Hyperconverged with vSAN C225 M8 Rack Server family
The Cisco Compute Hyperconverged C225 M8 Node family delivers performance, flexibility, and resiliency in a small footprint. Physically, nodes are deployed into clusters, with a cluster consisting of two or more Cisco Compute Hyperconverged C225 M8 All-NVMe servers.
The Cisco Compute Hyperconverged C225 M8 Node family is powered by 5th Gen AMD EPYC™ Processors with 150 percent more cores per socket designed using AMD’s chiplet architecture. With advanced features such as AMD Infinity Guard, compute-intensive applications will see significant performance improvements and reap other benefits such as power and cost efficiencies.
These servers can be interconnected and managed in two different ways:
● Cisco Intersight® Standalone Mode: The servers (nodes) are connected to a pair of Top-of-Rack (ToR) switches and are centrally managed using Cisco Intersight (SaaS, Connected Virtual Appliance (CVA), or Private Virtual Appliance (PVA)). While a minimum of three nodes are required to deploy a standard vSAN cluster, we also offer an option to deploy remote offices / branch offices (ROBO) that have a small number of workloads but require high availability. Refer to the Cisco spec sheets for further details on the use of two-node vSAN clusters.
● Cisco Intersight Managed Mode: The nodes are connected to a pair of Cisco UCS 6400 Series or a pair of Cisco UCS 6500 Series fabric interconnects running in Intersight Managed Mode (IMM) and managed as a single system using Cisco Intersight (SaaS, Connected Virtual Appliance (CVA), or Private Virtual Appliance (PVA)). These clusters can be deployed with a minimum of two nodes (two-node cluster) for remote-office/branch-office environments. A standard vSAN cluster requires a minimum of three nodes and can scale up to 64 nodes in a single cluster. These clusters can support both general-purpose deployments and mission-critical high-performance environments.
Note: Cisco UCS Managed Mode (UMM) is not recommended. M8 will be the last generation of hardware that will support UMM. It is recommended to deploy all new clusters in Intersight Managed Mode or in Intersight Standalone Mode.
Cisco Compute Hyperconverged C225 M8 All-NVMe with 5th Gen AMD EPYC processors are excellent for a wide range of workloads, including virtualization, collaboration, and bare-metal applications.

|
| Cloud-based services and management |
Cisco Intersight simplifies infrastructure operations across on-premises data centers, edge sites, and public clouds.
● Use a software-as-a-service platform that bridges applications with infrastructure.
● Correlate visibility and management across bare-metal servers, hypervisors, and application components.
● Transform operations with artificial intelligence to reach needed scale and velocity.
|
● VMware vCenter is the centralized management platform for vSphere environments, including vSAN:
● Configure, control, scale, and monitor your vSphere environment.
● Exercise full control over virtual machines (VMs), virtualization layer, and software-defined storage.
● Leverage the Distributed Resource Scheduler (DRS) to balance workloads across the cluster.
|
| Storage |
● U.2/U.3 All-NVMe configurations
