VxRail server nodes are designed and engineered for VxRail. The PowerEdge server goes through VxRail product engineering specifications to produce a VxRail node ready for shipment. The components that are manufactured into VxRail nodes are based on the purchase order. The set of VxRail nodes is delivered ready for data center installation and connectivity into the data center network infrastructure.
VxRail models
After data center installation and network connectivity are complete and equipment is powered on, the VxRail management interface initializes the process that forms a VxRail cluster. A VxRail cluster starts with two nodes and can scale to a maximum of 64 nodes. Planned business use cases, and factors such as performance, capacity, and network connectivity are best achieved by using VxRail nodes to form a cluster.
The VxRail naming standards are structured to target specific objectives:
E Series: Balanced compute and storage.
V Series: Virtual desktop enablement with support for GPUs.
P Series: High performance.
S Series: Dense storage.
Newer VxRail models use a naming standard that is more closely aligned with PowerEdge naming standards. This naming standard now uses a two-character prefix instead of a single character. The naming standard consolidates three target objectives from the previous standard under a single model series.
VE-Series: Balance compute and storage requirements.
VP-Series: Support multiple business objectives, including high performance, storage density, and GPUs.
VD-Series: Ruggedized, short-depth, sled-based models for space optimization
Each VxRail series offers choices for network connectivity. Every VxRail node includes support for base connectivity through onboard Ethernet ports. Network expansion is supported on VxRail nodes using available PCIe slots for Ethernet adapter cards. The number and type of PCIe slots that can be used for networking purposes depends on the model and the hardware configuration.
The following figures show physical network port options for the VxRail models:

With the 1U rack mount models such as the VE-Series and E-Series, you can use PCIe slots for network expansion. Certain models support low-profile PCIe slots and full-height PCIe slots. The number and type of slots on each node depend on the configured hardware options and support for the GPUs.

The 2U models offer a higher number of PCIe slots compared to 1U models. When you order 2U models, you can configure them to address use cases that can reduce the number of available PCIe slots. For instance, network expansion options are reduced when slots are populated with storage devices or GPUs.

The VxRail VD-Series support 1U and 2U size sleds. Both sled options are supported in rackable chassis or stackable chassis. Only the 2U sleds support network expansion outside of the onboard Ethernet ports through PCIe slots.
