Chapter 1. Introduction
The ThinkAgile VX7820 Appliance and VX 4U Certified Node are high performance 4U rack servers that
support up to four Intel Xeon processors. They are enterprise-class servers designed for customers requiring
four processors, large amounts of memory, and numerous I/O connections. In addition, they are designed to
simplify vSAN deployment and management for customers through predefined server configurations that are
optimized around specific types of workloads. They are preinstalled with VMware ESXi and conform to best
practices and compliance guidelines for vSAN.
Note:
A VMware vSAN cluster requires a minimum of three servers. 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.
In addition, the servers are designed to utilize the Lenovo system management tools to create a unified
hardware management solution for vSAN deployments:
•
Lenovo XClarity Administrator
, which provides firmware compliance functionality to ensure that the
ThinkAgile VX MT 7Z12 and 7Z13 Series servers are running the appropriate level of firmware for Lenovo
XClarity Controller, UEFI, and PCIe devices.
•
Lenovo XClarity Integrator
, which provides VMware vCenter plug-in functionality so that ThinkAgile VX
MT 7Z12 and 7Z13 Series servers can be managed directly from vCenter.
The ThinkAgile VX MT 7Z12 and 7Z13 Series hardware is based on the SR950 rack server.

Typical vSAN architecture
A typical vSAN architecture includes three or more servers that are implemented as a single vSAN cluster.
Each server contributes storage to the vSAN 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 vSAN architecture:
