Dell EMC SC5020 Storage Array
Crank up the performance, crank down the cost
SC5020 makes storage cost savings automatic with a modern architecture that optimizes your data center for economics while delivering transformational SSD, HDD or hybrid performance.
SC Series provides the lowest effective price/GB for flash and hybrid flash*, giving companies of any size the technology advantage they need to compete in today’s fast-changing markets. Highlights include:
- Data Progression – Achieve IOPS goals with the least expensive mix of storage media, even as performance needs evolve
- Deduplication & Compression – Dramatically reduce the raw capacity required to store your data
- RAID tiering – Eliminate manual provisioning, increase efficiency and utilization
- Federation – Simplify multi-array environments with quick and seamless data movement, plus proactive load balancing assistance via Live Migrate and Volume Advisor
- ProSupport Services – Reduce deployment costs with remote installation options that ensure your project goes right the first time.
- Persistent software licensing – Future-proof your investment, minimize the cost of upgrades and expansions
All-new hardware platform
Designed as the next-generation successor to the popular SC4020 array, SC5020 is a performance powerhouse. With dual 8-core Intel processors, 4x more memory and a 12Gb SAS back end, the SC5020 delivers
The new 3U “all-in-one” chassis includes 30 drive bays plus dual hot-swappable controllers, providing up to 460TB raw capacity in a single compact unit. A variety of expansion enclosures lets you scale over 2PB* per array – with even larger scale-out potential in federated multi-array systems.
But the advantages don’t stop with fast hardware. SC5020 includes all the Storage Center Operating System (SCOS) features you’ve come to expect from SC Series storage.
Intelligent advantage for modern workloads
Based on actual use and application performance requirements, SC Series Data Progression dynamically tunes multiple drive tiers and manages 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 (on the same drives) for subsequent reads.
As data ages, it’s moved to less expensive storage until it becomes more active again. Data is precisely where it’s needed, when it’s needed – the perfect combination of high IOPs and cost savings.
0-100% Flash architecture
Target specific price/performance ratios with any mix of SSDs and HDDs – then modify the mix as your needs change. Add more flash to boost performance, or “cheap and deep” spinning disk as cold data volumes grow. Hot data will always be written to your fastest drives at the fastest RAID levels.
Intelligent Data Reduction
Like many SC services, Deduplication and Compression are applied dynamically at a sub-LUN level to optimize performance and reduce capacity needs throughout the data lifecycle. Fully integrated with Data Progression, SC data reduction saves money on SSDs, HDDs – or both in hybrid systems.
Low-Cost Business Continuity
Keep mission-critical apps running during unexpected outages and disasters with seamless volume-level auto-failover between local and remote arrays. Innovative Live Volume feature is native to SCOS – no extra hardware or software is required to create your “always available” storage environment.
Reliable SC Series investment protection
Despite its low initial and lifecycle costs, SC5020 includes all the advanced tools and integrations you need to be sure your array continues to provide value as your business grows.

4:1 All-Flash Storage Efficiency Guarantee
SC Series arrays are efficient in ANY configuration (all-flash, hybrid and HDD) – but we know many businesses are especially concerned about expense when deploying all-flash arrays. That’s why we’re taking the risk out of AFAs by guaranteeing 4:1 efficiency for all-flash SC configurations. Dell EMC promises our all-flash arrays will provide an effective logical storage capacity at least four times the physical capacity of your purchased drives – or we’ll give you more drives at no charge.*
