VxFlex integrated rack deployment options

VxFlex integrated rack has several options for deployment.

VxFlex OS runs on VxFlex integrated rack nodes to operate the storage and tie in workloads. VxFlex OS has three components:

  • Storage data client (SDC): Consumes storage from the VxFlex integrated rack
  • Storage data server (SDS): Contributes node storage to VxFlex integrated rack
  • Metadata manager (MDM): Manages the storage blocks and tracks data location across the system

VxFlex OS enables flexible deployment options by allowing the separation of SDC and SDS components. It addresses data center workload requirements through the following VxFlex integrated rack deployment options:

Deployment type Description
Full hyperconverged

Consists of VxFlex hyperconverged nodes, which contribute both compute and storage resources to the virtual environment.

Front-end (application) and back-end (storage) traffic share the same VxFlex OS data networks. This includes VxFlex hyperconverged nodes and VxFlex storage-only nodes with NVMe.

NVDIMM data compression is supported on VxFlex hyperconverged nodes and VxFlex storage-only nodes.

Two-layer

Separates compute resources from storage resources, allowing the independent expansion of compute or storage resources.

Consists of VxFlex compute-only nodes (supporting the SDC) and VxFlex storage-only nodes (connected to and managed by the SDS). VxFlex compute-only nodes host end-user applications. VxFlex storage-only nodes contribute storage to the system pool.

Hybrid hyperconverged

Consists of VxFlex hyperconverged nodes, VxFlex compute-only nodes, and VxFlex storage-only nodes. Some VxFlex nodes contribute both compute resources and storage resources (VxFlex hyperconverged nodes), some contribute only compute resources (VxFlex compute-only nodes), and some contribute only storage resources (VxFlex storage-only nodes).

Microsoft Windows-based compute-only Consists of VxFlex compute-only nodes (supporting the SDC) on Microsoft Windows 2016 or 2019 Standard/Datacenter. VxFlex compute-only nodes host end-user applications.
Storage-only

Consists of nodes that contribute storage resources to the virtual environment. The back-end traffic shares the same VxFlex OS data networks. The storage-only VxFlex integrated rack provide volumes to an external customer compute limited to Dell EMC PowerEdge servers.

No SDC components are installed on these nodes.

Two-layer deployments allow rebooting of VMware cluster nodes without VxFlex OS ramifications.

When designing initial deployment or specifying later growth, use VxFlex hyperconverged nodes if both VxFlex compute-only nodes and VxFlex storage-only nodes are needed. You can add VxFlex compute-only nodes or VxFlex storage-only nodes as needed.

To control the number of processors or cores, consider separating the compute for the application from the VxFlex nodes that support storage. This deployment is a pure two-layer deployment. Extra workloads are supported or added on
  • VxFlex hyperconverged nodes
  • Two-layer VxFlex compute-only nodes
  • VxFlex storage-only nodes
This creates a hybrid deployment.
