Chapter 2

Topologies and Operating Modes

This chapter provides a functional overview of the supported operating modes 
and topologies for the NexStor 4200F Series Storage System. Information 
contained in this chapter should provide you with an understanding to make the 
best choice to optimize your storage system solution.

Essentially there are two operating modes available: Simplex (Stand-Alone) and 
Duplex (Active-Active). The NexStor 4210F model with its single RAID controller 
supports the simplex operating mode, and the NexStor 4220F with its dual RAID 
controllers supports the duplex or active-active operating mode.

Operating Mode Overview

These operating modes allow you to configure the enclosure’s drives and RAID 

controller(s) to support a variety of host environments topologies.

■

Simplex – In this operating mode, the enclosure is configured as a RAID 

storage system with its single RAID controller operating autonomously. 

This mode supports a dual port topology.

■

Duplex – In this operating mode, the enclosure is configured as a RAID 

storage system with dual controllers operating in an active-active 

fault-tolerant configuration. This mode supports both Multi-TID and 

Multi-Port topologies.
