DCT appliance requirements

Technical requirements

The minimum requirements for a DCT engine are as follows:

  • CPU: 8 vCPU

  • Memory: 16GB RAM

    • Higher memory allocation (32GB/64GB) may be required with features like Delphix AI Services.

  • Storage: 128GB system disk + 50GB disk (metadata volume)

Internal network range

DCT appliance allocates private IP addresses for its own internal use from this reserved private range: 172.31.254.0/24.

If your environment routes or uses any of these ranges, you may experience connectivity issues accessing the DCT appliance UI or API from hosts on those sub-nets. Contact Delphix Support to discuss network configuration options for your deployment.

Cloud marketplace images and VMWare OVA files may be provided with a default set of allocated CPU and memory resources, which is higher than the minimum requirement. These should provide a good user experience for most sizes of Delphix infrastructure.
Planning for disaster recovery? If this appliance will be a disaster recovery secondary, it needs additional storage and specific firewall rules. See Automated disaster recovery for sizing and network requirements before you provision it.

Supported platforms

A DCT engine can be deployed with the following methods:

  • Amazon Web Services (AWS) — AMI

  • Microsoft Azure — Marketplace

  • Google Cloud Platform (GCP) — custom image

  • Hyper-V — VHDX

  • KVM-based hypervisors — qcow2 image

  • Oracle Cloud Infrastructure (OCI) — OVA import

  • VMware ESXi — OVA

AWS

Any AWS instance type that meets the minimum requirements above is acceptable. You can share the AMI to your account in the Delphix download portal. See the "Procedure to install an AMI" section in the Deploy on AWS topic for more.

Azure

Any Azure instance type that meets the minimum requirements above is acceptable. Deployment is performed through the Azure Marketplace.

ESXi

  • VMware Cloud

  • VMware ESXi 7.0, 7.0 U1, 7.0 U2, 7.0 U3

  • VMware ESXi 8.0, 8.0 U1, 8.0 U2, 8.0 U3

GCP

Any GCP general-purpose machine type that meets the minimum requirements above is acceptable. See GCP requirements for machine type guidance, networking, and storage details.

Hyper-V

Any Hyper-V host that meets the minimum requirements above is acceptable. See Hyper-V requirements for supported versions, sizing, and storage details.

KVM

Any KVM-based hypervisor whose vendor supports the Ubuntu 24.04 guest operating system is acceptable, including Nutanix AHV and Proxmox VE via KVM compatibility. See KVM requirements for sizing, storage, and networking details.

OCI Cloud
