1 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 expansion enclosures.

To allow for storage expansion, the SCv2000/SCv2020 storage system supports multiple SC100/SC120 expansion enclosures..

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 four-column, 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.

About the SCv2000/SCv2020 Storage System9

Expansion Enclosures

Expansion enclosures allow the data storage capabilities of the SCv2000/SCv2020 storage system to be expanded beyond the 12 or 24 internal disks in the storage system chassis.

The SCv2000/SCv2020 storage system supports a total of 168 disks per Storage Center system. This total includes the disks in the storage system chassis and the disks in the SC100/SC120 expansion enclosures.?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 disk 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 disk 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 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: 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.

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

10About the SCv2000/SCv2020 Storage System

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 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.

When replication is licensed, the SCv2000/SCv2020 can use the front-end 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 front-end iSCSI ports to replicate data to another Storage Center.

?SAS: Hosts or servers access storage by connecting directly to the storage system SAS ports.

NOTE: When 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.

Back-End Connectivity

Back-end connectivity is strictly between the storage system and expansion enclosures, which hold the physical drives that provide back-end expansion storage.

An SCv2000/SCv2020 storage system supports back-end connectivity to multiple expansion enclosures.

14About the SCv2000/SCv2020 Storage System

System Administration

To perform system administration, the Storage Center communicates with computers using the Ethernet management (MGMT) port.

The Ethernet management port is used for Storage Center configuration, administration, and management.

NOTE: The baseboard management controller (BMC) does not have a separate physical port on the SCv2000/SCv2020. The BMC is accessed through the same Ethernet management port that is used for Storage Center configuration, administration, and management.

SCv2000/SCv2020 Storage System Hardware

The SCv2000/SCv2020 storage system ships with Dell Enterprise drives, two redundant power supply/ cooling fan modules, and either one storage controller or two redundant storage controllers.

Each storage controller contains the front-end, back-end, and management communication ports of the storage system.
