• SCv3000 and SCv3020 Storage System Hardware
Storage Center Hardware Components
The Storage Center described in this document consists of an SCv3000 and SCv3020 storage system, expansion enclosures, and
enterprise-class switches.
To allow for storage expansion, the SCv3000 and SCv3020 storage system supports multiple SCv300 and SCv320 and SCv360 expansion
enclosures.
: The cabling between the storage system, switches, and host servers is referred to as front‐end connectivity. The cabling
NOTE
between the storage system and expansion enclosures is referred to as back-end connectivity.
SCv3000 and SCv3020 Storage System
The SCv3000 and SCv3020 storage systems contain two redundant power supply/cooling fan modules, and two storage controllers with
multiple I/O ports. The I/O ports provide communication with host servers and expansion enclosures. The SCv3000 storage system
contains up to 16 3.5-inch drives and the SCv3020 storage system contains up to 30 2.5-inch drives.
The SCv3000 Series Storage Center supports up to 222 drives per Storage Center system. This total includes the drives in the storage

Expansion Enclosures
Expansion enclosures allow the data storage capabilities of the SCv3000 and SCv3020 storage system to be expanded beyond the 16 or
30 drives in the storage system chassis.
The SCv3000 and SCv3020 support up to 16 SCv300 expansion enclosures, up to eight SCv320 expansion enclosures, and up to three
SCv360 expansion enclosures.
Switches
Dell oers enterprise-class switches as part of the total Storage Center solution.
The SCv3000 and SCv3020 storage system supports Fibre Channel (FC) and Ethernet switches, which provide robust connectivity to
servers and allow for the use of redundant transport paths. Fibre Channel (FC) or Ethernet switches can provide connectivity to a remote
Storage Center to allow for replication of data. In addition, Ethernet switches provide connectivity to a management network to allow
conguration, administration, and management of the Storage Center.
Storage Center Communication
A Storage Center uses multiple types of communication for both data transfer and administrative functions.
Storage Center communication is classied into three types: front end, back end, and system administration.
Front-End Connectivity
Front-end connectivity provides I/O paths from servers to a storage system and replication paths from one Storage Center to another
Storage Center. The SCv3000 and SCv3020 storage system provides the following types of front-end connectivity:
• Fibre Channel – Hosts, servers, or network-attached storage (NAS) appliances access storage by connecting to the storage system
Fibre Channel ports through one or more Fibre Channel switches. Connecting host servers directly to the storage system, without using
Fibre Channel switches, is not supported.
• iSCSI – Hosts, servers, or network-attached storage (NAS) appliances access storage by connecting to the storage system iSCSI ports
through one or more Ethernet switches. Connecting host servers directly to the storage system, without using Ethernet switches, is
not supported.
• SAS – Hosts or servers access storage by connecting directly to the storage system SAS ports.
When replication is licensed, the SCv3000 and SCv3020 can use the front-end Fibre Channel or iSCSI ports to replicate data to another
Storage Center.

Back-End Connectivity
Back-end connectivity is strictly between the storage system and expansion enclosures.
The SCv3000 and SCv3020 storage system supports back-end connectivity to multiple SCv300, SCv320, and SCv360 expansion
enclosures.
System Administration
To perform system administration, the Storage Center communicates with computers using the Ethernet management (MGMT) port on
the storage controllers.
The Ethernet management port is used for Storage Center conguration, administration, and management.
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 SCv3000 and SCv3020 storage system supports replication to the storage systems listed below. However, a Storage Manager Data
Collector must be used to replicate data between the storage systems. For more information about installing and managing the Data
Collector and setting up replications, see the Storage Manager Installation Guide.

Power Supply and Cooling Fan Modules
The SCv3000 and SCv3020 storage system supports two hot-swappable power supply/cooling fan modules.
The cooling fans and the power supplies are integrated into the power supply/cooling fan module and cannot be replaced separately. If one
power supply/cooling fan module fails, the second module continues to provide power to the storage system.
NOTE: When a power supply/cooling fan module fails, the cooling fan speed in the remaining module increases signicantly to
provide adequate cooling. The cooling fan speed decreases gradually when a new power supply/cooling fan module is installed.
CAUTION: A single power supply/cooling fan module can be removed from a powered on storage system for no more than 90
seconds. If a power supply/cooling fan module is removed for longer than 90 seconds, the storage system might shut down
automatically to prevent damage.
