Deployment Guide

Storage Center Architecture Options
A Storage Center with an SCv2000/SCv2020 storage system can be deployed in the following configurations:
• An SCv2000/SCv2020 storage system deployed without SC100/SC120 expansion enclosures.
Figure 1. SCv2000/SCv2020 without Expansion Enclosures
• An SCv2000/SCv2020 storage system deployed with one or more SC100/SC120 expansion enclosures.
NOTE: An SCv2000/SCv2020 storage system with a single storage controller cannot be deployed with expansion
enclosures. The storage system must have two storage controllers to connect to expansion enclosures.
NOTE: A single storage controller will have the cache disabled even though there might be a cache battery backup
installed. The battery is present on single controllers to support a future upgrade to a dual controller.

Storage Center Replication
Storage Center sites can be collocated or remotely connected and data can be replicated between sites. Storage Center replication
can duplicate volume data to another site in support of a disaster recovery plan or to provide local access to a remote data volume.
Typically, data is replicated remotely as part of an overall disaster avoidance or recovery plan.
The SCv2000 series Storage Center supports replication to other SCv2000 series Storage Centers. However, a Dell Storage
Manager Data Collector must be used to replicate data between the storage systems.
For more information about installing, managing the Data Collector, and setting up replications, see the Dell Storage Manager
Administrator’s Guide .
Storage Center Communication
A Storage Center uses multiple types of communication for both data transfer and administrative functions.
Storage Center communication is classified into three types: front end, back end, and system administration.
