Dell EMC SC7020
Intuitive management at your fingertips
From convenient web management from your mobile device (Unisphere for SC) to cloud-based analytics and monitoring (CloudIQ) or robust client-side software (Dell Storage Manager), SC7020 has the control points you need to streamline day-to-day tasks, smooth major migrations, and keep all your data fully available and optimized.
SC Series management helps you reduce operating costs with advanced and automated features, including easy data replication between SC and PS Series arrays, which gives PS customers flexibility to add SC arrays to their environment when they choose.
A new level of Storage Center OS efficiency
SCOS 7 is a groundbreaking leap forward in the evolution of Dell EMC SC platform, offering diverse envrionments the ideal access point to deploy uniquely adaptable, future-ready storage solutions. New capabilities include:
- Over 10:1 capacity savings with intelligent deduplication and compression*
- Federated data control with Live Migrate
- Seamless business continuity with Live Volume auto-failover between arrays
- Federated management and cross-platform replication between SC and PS Series arrays
- Quality-of-Service (QoS), VMware Virtual Volumes (VVols) support,iSCSI Datacenter Bridging (DCB)
See individual spec sheets and product documentation for additional features and specific platform support.
Self-optimizing, automated storage
Based on actual use and application performance requirements, SC Series Data Progression automatically optimizes your drive tiers and RAID levels for performance and cost savings. By default, all new data is written to fastest Tier 1 drives at RAID 10 performance levels, then converted to economical RAID 5/6 for subsequent reads.
As data ages, it’s moved to less expensive storage until it becomes active again. All-flash and hybrid arrays can leverage the unique attributes of write- and read-intensive SSDs in combination. Data is precisely where it’s needed, when it’s needed – the perfect combination of high IOPS and cost savings.
Space savings in the data center
SC Series delivers unprecedented levels of platform efficiency, along with comprehensive data reduction and:
- Conservation of rack space for future growth
- Smaller footprint, which benefits power and cooling expenses
- Intelligent deduplication and compression for all storage tiers and drive types
Operating costs are reduced with advanced features like volume-level QoS, VVols support and departmental “charge-back” reporting, allowing instant visibility and control of a multi-terabyte, multi-location environment.
Data center automation with leading technology partner integrations
SC Series features a vast array of integration points with VMware, Microsoft, Oracle, OpenStack, IBM, CommVault, Symantec, Foglight and more. VMware® vSphere™ plug-in, vCenter™ SRM adapter and VAAI support help you manage storage and virtual machines together.
With the introduction of Application Protection Manager for Oracle and now enhanced for the Linux® environment, you can create application-consistent Replays for Oracle® databases. Combined with Storage Center Data Instant Replay (DIR), it will ensure reliable application, consistent backup and recovery of Oracle and Microsoft Volume Shadow Copy (VSS) enabled applications (Exchange, SQL and Hyper-V) and VMware virtual machines (VMs).
Conquer storage challenges now and in the future with the SC7020
Control the deluge of diverse data you manage and stay future-ready with the Dell EMC SC7020. The SC7020 combines more capacity and greater flexibility together in one system to simplify management and lower costs. The SC7020 offers flexible features that can help you achieve:
- Scalable IOPs with block data
- Over 10:1 capacity savings with intelligent deduplication and compression*
- Over 60 percent reduction in rack space required*

Flexibility and efficiency
Consolidate multiple types of workloads into a single array, and achieve agile performance and a rapid return on investment. The SC7020 lowers the cost per terabyte, for all array types, including hybrid or all flash options, and uses your current architecture.
Expand with your business: Grow when and how your business dictates with seamless scalability up to 500 drives.
Future-proofed data: Supports various array options: flash, hybrid, multi-protocol connectivity support, data protection, ProSupport Powered by Copilot Services and Dell EMC Deployment Services.
Optimized resources: Seamlessly manages your storage with a single pane of glass across the federated family of SC and PS Series.
Eliminate expense of managing separate systems
Manage the SC7020 with the Dell EMC Storage Manager (DSM, formerly known as Enterprise Manager). It provides comprehensive monitoring and management of all local and remote SC Series arrays. Easy-to-use data replication and migration between platforms gives PS customers flexibility to add SC arrays to their environment when they choose.*
DSM streamlines SAN administration and reduces operating costs with advanced features like volume-level QoS, VVOls support and departmental “charge-back” reporting. Powershell and REST management APIs allow you to integrate the SC7020 into your business workflows
Dell EMC SC Series expansion enclosures
Supporting up to 500 total drives and 3PB raw capacity in a single array, the SC7020 offers five supported expansion enclosures that you can mix and match depending on your specific performance, cost or density needs.
Options are available for ultra-dense (84 drives in 5U) with the SC280 and new high-performance 12Gb SAS SC400 and SC420 enclosures. Adding a new enclosure is simple – the new drives can be automatically assimilated into the existing virtualized pool or set up as their own standalone pool. Data-in-place upgrades make it easy to change controllers and other key components, or migrate from legacy SC Series arrays.
