Nutanix delivers the Disaster Recovery to Nutanix Cloud Clusters on AWS Design, as a bundled solution for general server virtualization that includes hardware, software, and services to accelerate and simplify the deployment and implementation process. This Validated Design features a full-stack solution for hybrid cloud deployments that integrates multiple products including AOS, AHV, Prism Pro, Calm, Flow, Leap, Mine, and HYCU.The Validated Design – Disaster Recovery to Nutanix Cloud Clusters on AWS Design sizer reference scenarios have the following features:
- The on-prem baseline configuration is comprised of three clusters:
- Management – 4-node cluster based on NX-1175S for Prism Central, Active Directory, IPAM, Load Balancing, SYSLOG, and any other management services.
- Workload – 4-16 nodes of NX-3170-G8 for general purpose server virtualization workloads.
- Backup – 4-node cluster of NX-8155-G8 for Mine/Hycu
- The AWS baseline configuration is comprised of three clusters:
- Management – 4-node cluster based on m5d.metal for Prism Central, Active Directory, any other management services.
- Workload– 2 * 4-16 nodes of i3en.metal for general purpose server virtualization workloads. At the time of testing Nutanix only supported a 16 node cluster in AWS.
A dedicated management cluster in each Availability Zone provides increased availability, security, operations, and performance. The workload cluster has a defined maximum size of 16 nodes, which provides a reasonable maintenance window for rolling firmware and software upgrades. Smaller workload clusters can be deployed, but the maximum size should not exceed 16 nodes.
- NVD Defines standard VM “t-shirt” sizes for deployment via Calm:
| Small | Medium | Large |
| 1 vCPU | 2 vCPU | 4 vCPU |
| 8 GB RAM | 16 GB RAM | 32GB RAM |
| 50GB SSD | 100GB SSD | 200GB SSD |
- When using the defined VM sizes, the on-prem per-workload cluster maximums are:
| Small VMs | Medium VMs | Large VMs | |
| Maximum running VMs per on-premises workload cluster building block | 1,860 | 1,380 | 690 |
| Maximum running VMs per node on-premises | 124 | 92 | 46 |
| Maximum deployed VMs per workload cluster on AWS | 1,350 | 675 | 330 |
| Maximum running VMs per node on AWS Workload Cluster | 90 | 45 | 22 |
- Due to quoting limitations, a single Availability Zone has two sizer scenarios: Management + Workload cluster, and Backup Cluster. Note that the Hycu software license is not included, and must be purchased separately via other channels.
- Services SKUs are not included in the Sizer reference scenarios. Review the BOM in the NVD appendix for the complete list of Services SKUs which should be included.
It is extremely important to review the entire Hybrid Cloud: Disaster Recovery to Nutanix Cloud Clusters on AWS Design on the Solutions Support portal to understand the complete Hybrid Cloud validated solution.
