• Dell Storage Client Administrator’s Guide Provides information about the Dell Storage Client and how it can be used to manage a Storage Center. • Dell Storage Center Software Update Guide Describes how to upgrade Storage Center software from an earlier version to the current version.
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.
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.
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.
SCv2000/SCv2020 Storage System with Fibre Channel Front-End Connectivity An SCv2000/SCv2020 storage system with Fibre Channel front-end connectivity may communicate with the following components of a Storage Center system.
SCv2000/SCv2020 Storage System with iSCSI Front-End Connectivity An SCv2000/SCv2020 storage system with iSCSI front-end connectivity may communicate with the following components of a Storage Center system.
SCv2000/SCv2020 Storage System with SAS Front-End Connectivity An SCv2000/SCv2020 storage system with SAS front-end connectivity may communicate with the following components of a Storage Center 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.

SCv2000/SCv2020 Drives Dell Enterprise hard disk drives (HDDs) and Enterprise Solid-State Drives (eSSDs) are the only drives that can be installed in an SCv2000/SCv2020 storage system. If a non-Dell Enterprise drive is installed, Storage Center prevents the drive from being managed.
SC100/SC120 Expansion Enclosure Overview The SC100 is a 2U expansion enclosure that supports up to 12 3.5 ‐ inch hard drives installed in a four ‐ column, three-row configuration. The SC120 is a 2U expansion enclosure that supports up to 24 2.5 ‐ inch hard drives installed vertically side ‐ by ‐ side.

SC100/SC120 Expansion Enclosure EMM Features and Indicators The SC100/SC120 includes two Enclosure Management Modules (EMMs) in two interface slots. Figure 19. SC100/SC120 EMM Features and Indicators Item Name Icon Description 1 System status indicator Not used on SC100/SC120 expansion enclosures.
SC100/SC120 Expansion Enclosure Drives Dell Enterprise hard disk drives (HDDs) and Enterprise Solid-State Drives (eSSDs) are the only drives that can be installed in SC100/SC120 expansion enclosures. If a non-Dell Enterprise drive is installed, Storage Center prevents the drive from being managed.
2 Install the Storage Center Hardware Prepare for the installation, mount the equipment in a rack, and install the disks. Unpack and Inventory the Storage Center Equipment Unpack the storage system and identify the items in your shipment. Figure 23. SCv2000/SCv2020 Storage System Components 1.
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.
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.
NOTE: The storage system and expansion enclosures each require 2U of rack space for installation. 3. Position a rail at the marked location and extend the rail to fit the rack. 4. Insert the two rail pins into the pin holes. Figure 24. Hole Locations in Rack 1.
3 Front-End Cabling Front-end cabling refers to the connections between the storage system and external devices such as host servers or another Storage Center. Front ‐ end connections can be made using Fibre Channel, iSCSI, or SAS interfaces. Dell recommends connecting the storage system to host servers using the most redundant option available.
Storage Controller Redundancy To allow for storage controller redundancy, a front-end port on each storage controller must be connected to the same switch or server. If a storage controller becomes unavailable, the front-end ports on the offline storage controller move over to the ports (in the same fault domain) on available storage controller.
Cabling SAN-Attached Host Servers An SCv2000/SCv2020 storage system with Fibre Channel or iSCSI front-end ports connects to host servers through Fibre Channel or Ethernet switches. • A storage system with Fibre Channel front-end ports connects to one or more FC switches, which connect to one or more host servers.
• Storage controller 1: port 2 to FC switch 2 • Storage controller 2: port 2 to FC switch 2 Example Figure 26. Storage System with Dual 16 Gb Storage Controllers and Two FC Switches 1. Server 1 2. Server 2 3. FC switch 1 (Fault Domain 1) 4. FC switch 2 (Fault Domain 2) 5.
Steps 1. Connect each server to both FC fabrics. 2. Connect fault domain 1 (shown in orange) to fabric 1. • Storage controller 1: port 1 to FC switch 1 • Storage controller 1: port 3 to FC switch 1 • Storage controller 2: port 1 to FC switch 1 • Storage controller 2: port 3 to FC switch 1 3.
One Fibre Channel Fabric with Dual 16 Gb 2–Port Storage Controllers Use one Fibre Channel (FC) fabric to prevent an unavailable port or storage controller from causing a loss of connectivity between the host servers and a storage system with dual 16 Gb 2–port storage controllers .
Next steps Install or enable MPIO on the host servers. NOTE: After the Storage Center configuration is complete, run the host access wizard to configure host server access and apply MPIO best practices. For the latest best practices, see the Dell Storage Center Best Practices document located on the Dell TechCenter ( http://en.
Example Figure 29. Storage System with Dual 8 Gb Storage Controllers and One FC Switch 1. Server 1 2. Server 2 3. FC switch (Fault domain 1 and fault domain 2) 4. Storage system 5. Storage controller 1 6. Storage controller 2 Next steps Install or enable MPIO on the host servers.
Storage controller: port 1 to FC switch 1. 3. Connect fault domain 2 (shown in blue) to the fabric 2. Storage controller: port 2 to FC switch 2. Example Figure 30. Storage System a Single 16 Gb Storage Controller and Two FC Switches 1. Server 1 2. Server 2 3.
Steps 1. Connect each server to both FC fabrics. 2. Connect fault domain 1 (shown in orange) to fabric 1. • Storage controller 1: port 1 → FC switch 1 • Storage controller 1: port 3 → FC switch 1 3. Connect fault domain 2 (shown in blue) to fabric 2.
Using SFP+ Transceiver Modules An SCv2000/SCv2020 storage system with 16 Gb Fibre Channel storage controllers comes with short range small-form-factor pluggable (SFP+) transceiver modules. Figure 32. SFP+ Transceiver Module with a Bail Clasp Latch The SFP+ transceiver modules are installed into the ports of the SCv2000/SCv2020 storage controller.
