About the SCv2000/SCv2020 Storage System
The SCv2000/SCv2020 storage system provides the central processing capabilities for the Storage Center Operating System (OS) and management of RAID storage.
The SCv2000/SCv2020 storage system holds the physical disks that provide storage for the Storage Center. If additional storage is needed, the SCv2000/SCv2020 also supports SC100/SC120 expansion enclosures.
Storage Center Hardware Components
The Storage Center described in this document consists of an SCv2000 or SCv2020 storage system, enterprise-class switches, and SC100/SC120 expansion enclosures.
The SCv2000/SCv2020 storage system supports multiple SC100/SC120 expansion enclosures to allow for storage expansion.
NOTE: The cabling between the storage system, switches, and host servers is referred to as front end connectivity. The cabling between the storage system and expansion enclosures is referred to as back-end connectivity.
SCv2000/SCv2020 Storage System
The SCv2000 and SCv2020 are 2U storage systems with built-in storage. The SCv2000 is a 2U storage system that supports up to 12 internal 3.5–inch hot-swappable SAS hard drives installed in a fourcolumn, three-row configuration. The SCv2020 is a 2U storage system that supports up to 24 internal 2.5–inch hot-swappable SAS hard drives installed vertically side-by-side.
The SCv2000/SCv2020 storage system contains two redundant power supply/cooling fan modules and up to two storage controllers with multiple IO ports that provide communication with servers and expansion enclosures.
Switches
Dell offers enterprise-class switches as part of the total Storage Center solution.
The SCv2000/SCv2020 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 configuration, administration, and management of the Storage Center.

Expansion Enclosures
An SCv2000/SCv2020 storage system supports multiple SC100/SC120 expansion enclosures. The expansion enclosures allow the data storage capabilities of the SCv2000/SCv2020 to be expanded beyond the 12 or 24 internal drives in the storage system chassis.
The SCv2000/SCv2020 storage system supports a total of 168 drives per Storage Center system. This total includes the drives in the SCv2000/SCv2020 storage system chassis and the drives in SC100/SC120 expansion enclosures chassis.
•The SCv2000 supports up to thirteen SC100 expansion enclosures, up to six SC120 expansion enclosures, or any combination of SC100/SC120 expansion enclosures as long as the total drive count of the system does not exceed 168.
•The SCv2020 supports up to twelve SC100 expansion enclosures, up to six SC120 expansion enclosures, or any combination of SC100/SC120 expansion enclosures as long as the total drive count of the system does not exceed 168.
Storage Center Architecture Options
A Storage Center with an SCv2000/SCv2020 storage system can be deployed in two configurations:
•An SCv2000/SCv2020 storage system without SC100/SC120 expansion enclosures.
Figure 1. SCv2000/SCv2020 without Expansion Enclosures
•An SCv2000/SCv2020 storage system with one or more SC100/SC120 expansion enclosures.
NOTE: A storage system with a single storage controller cannot be deployed with expansion enclosures. The storage system must have dual storage controllers to deploy expansion enclosures.

About the SCv2000/SCv2020 Storage System |
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 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, an Enterprise Manager Data Collector must be used to replicate data between the storage systems.
•For more information on installing an Enterprise Manager Data Collector, see the Dell Enterprise Manager Installation Guide.
•For more information on managing the Data Collector and setting up replications, see the Dell Enterprise 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.
Front-End Connectivity
Front-end connectivity provides IO paths from servers to a storage system and replication paths from one Storage Center to another Storage Center. The SCv2000/SCv2020 provides three 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.
When replication is licensed, the SCv2000/SCv2020 can use the Fibre Channel ports to replicate data to another Storage Center.
•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.
When replication is licensed, the SCv2000/SCv2020 can use the iSCSI ports to replicate data to another Storage Center
NOTE: If replication is licensed, the SCv2000/SCv2020 can use the embedded REPL port to perform iSCSI replication to another SCv2000 series Storage Center.
If replication is licensed and the Flex Port license is installed, the SCv2000/SCv2020 can use the embedded MGMT port to perform iSCSI replication to another SCv2000 series Storage Center. In addition, the SCv2000/SCv2020 can use the embedded MGMT and REPL ports as front-end iSCSI ports for connectivity to host servers when the Flex Port license is installed.
•SAS: Hosts or servers access storage by connecting directly to the storage system SAS ports.
NOTE: The front-end connectivity ports are located on the back of the storage system, but are designated as front-end ports.

Prepare the Installation Environment
Make sure that the environment is ready for Storage Center installation.
•Rack Space: There must be sufficient space in the rack to accommodate the storage system chassis, expansion enclosures, and switches.
•Power: Power must be available in the rack, and the power delivery system must meet the requirements of the Storage Center.
•Connectivity: The rack must be wired for connectivity to the management network and any networks that carry front-end IO from the Storage Center to servers.
Safety Precautions
Always follow these safety precautions to avoid injury and damage to Storage Center equipment.
If equipment described in the document is used in a manner not specified by Dell, the protection provided by the equipment may be impaired. For your safety and protection, observe the rules described in the following sections.
28 |
Install the Storage Center Hardware |
NOTE: See the safety and regulatory information that shipped with each Storage Center component. Warranty information may be included within this document or as a separate document.
Installation Safety Precautions
Follow these safety precautions:
•Dell recommends that only individuals with rack-mounting experience install an SCv2000/SCv2020 storage system in a rack.
•Make sure the storage system is fully grounded at all times to prevent damage from electrostatic discharge.
•When handling the storage system hardware, you should use an electrostatic wrist guard (not included) or a similar form of protection.
The storage system chassis MUST be mounted in a rack; the following safety requirements must be considered when doing so:
•The rack construction must be capable of supporting the total weight of the installed chassis and the design should incorporate stabilizing features suitable to prevent the rack tipping or being pushed over during installation or in normal use.
•To avoid danger of the rack toppling over, do not slide more than one chassis out of the rack at a time.
•The rack design should take into consideration the maximum operating ambient temperature for the unit, which is 57°C.
Electrical Safety Precautions
Always follow electrical safety precautions to avoid injury and damage to Storage Center equipment.
WARNING: Disconnect power from the storage system when removing or installing components that are not hot-swappable. When disconnecting power, first power down the storage system using the Dell Storage Client and then unplug the power cords from all the power supplies in the storage system.
•Provide a suitable power source with electrical overload protection. All Storage Center components must be grounded before applying power. Make sure that there is a safe electrical earth connection to power supply cords. Check the grounding before applying power.
•The plugs on the power supply cords are used as the main disconnect device. Make sure that the socket outlets are located near the equipment and are easily accessible.
•Know the locations of the equipment power switches and the room's emergency power-off switch, disconnection switch, or electrical outlet.
•Do not work alone when working with high-voltage components.
•Use rubber mats specifically designed as electrical insulators.
•Do not remove covers from the power supply unit. Disconnect the power connection before removing a power supply from the storage system.
•Do not remove a faulty power supply unless you have a replacement model of the correct type ready for insertion. A faulty power supply must be replaced with a fully operational module power supply within 24 hours.
•Unplug the storage system chassis before you move it or if you think it has become damaged in any way. When powered by multiple AC sources, disconnect all supply power for complete isolation.
Install the Storage Center Hardware |
29 |
Electrostatic Discharge Precautions
Always follow electrostatic discharge (ESD) precautions to avoid injury and damage to Storage Center equipment.
Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. The resulting electrical discharge can damage electronic components and printed circuit boards. Follow these guidelines to protect your equipment from ESD:
•Dell recommends that you always use a static mat and static strap while working on components in the interior of the storage system chassis.
•Observe all conventional ESD precautions when handling plug-in modules and components.
•Use a suitable ESD wrist or ankle strap.
•Avoid contact with backplane components and module connectors.
•Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use.
General Safety Precautions
Always follow general safety precautions to avoid injury and damage to Storage Center equipment.
•Keep the area around the storage system chassis clean and free of clutter.
•Place any system components that have been removed away from the storage system chassis or on a table so that they are not in the way of foot traffic.
•While working on the storage system chassis, do not wear loose clothing such as neckties and unbuttoned shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling fan.
•Remove any jewelry or metal objects from your body because they are excellent metal conductors that can create short circuits and harm you if they come into contact with printed circuit boards or areas where power is present.
•Do not lift a storage system chassis by the handles of the power supply units (PSUs). They are not designed to hold the weight of the entire chassis, and the chassis cover may become bent.
•Before moving a storage system chassis, remove the PSUs to minimize weight.
•Do not remove drives until you are ready to replace them.
NOTE: To ensure proper storage system cooling, hard drive blanks must be installed in any hard drive slot that is not occupied.
Install the Storage System in a Rack
Install the storage system and other Storage Center system components in a rack.
About this task
