Typical Nutanix architecture
A typical Nutanix architecture includes three or more servers that are implemented as a single Nutanix
cluster.
Each server contributes storage to the Nutanix cluster from the local disks on the server:
• Hybrid Cluster – The server provides a combination of solid state disks (SSDs) for caching and hard disk
drives (HDDs) for storage capacity.
• All-Flash Cluster – The server provides SSDs for caching and SSDs for storage capacity.
The following figure provides a conceptual view of the Nutanix architecture:

HX deployment architecture
When deploying a ThinkAgile HX Series solution, the best practice is to use three or more servers of the
same machine type and configuration to provide a balanced and high-performance solution. However, some
specialized systems might be used in conjunction, such as “-C” nodes. In addition, 1–node and 2–node
clusters are supported using ThinkAgile HX1321 Series nodes. Lastly, a 1–node replication target is possible,
using the ThinkAgile HX1521-R.
The systems are connected through switches for management and data:
• A dedicated management network is used by the Lenovo XClarity Administrator to communicate with the
Lenovo XClarity Controller (XCC) on each of the ThinkAgile HX Series servers.
• A redundant 10Gbps Ethernet network is used for NDFS data traffic and user VM traffic. The redundant
Ethernet network is implement through two top-of-rack switches, such as the Lenovo ThinkSystem
NE1032 RackSwitch.
