Dell EMC has brought customers a product line “perfect” for the mid-range storage segment. With 2 controller architecture working at the same time, with storage virtualization, automatic data classification (auto-tiering), thin allocation, compression and anti-duplication, encryption, link and copper The set between many of the same type of dish cabinets, SC-series is suitable for all needs of businesses. For applications requiring high I / O performance, the All-flash SC5020F, SC7020F can deliver up to 1,000,000 IOPS.
SCv3000, SCv3020, SC5020, SC5020F, SC7020F, SC7020 and SC9000 models are able to support FC and iSCSI storage protocols simultaneously.

Data Optimization
Auto-tiering method Policy-based migration based on real-time data usage, customizable 512KB-4MB page size.
Auto-tiering structure Up to 3 primary (media-based) tiers total, up to 2 SSD tiers (write- and read-intensive SSDs)
RAID tiering Auto-license and dynamically restripes multiple RAID levels on the same tier; eliminates need to pre-allocate RAID groups
Tiering customizations User-defined profiles, option to “pin” volumes to any tier or RAID level
RAID support RAID 0, 1, 5, 6, RAID 10, and RAID 10 DM (Dual Mirror); any combination of RAID levels can exist in single array
Thin provisioning Active by default on all volumes, operates at full performance across all features
Thin snapshots Records changes only, snapshots auto-migrate to lower-cost storage
Intelligent deduplication and compression Compression only, selectable option per volume Selectable option per volume.
“Deduplication + compression” mode.
“Compression-only” mode.
