After reading several SCv2000 reviews, I found it’s simply an upgraded version of PowerVault, so I seriously doubt the performance is even near Equallogic PS4100 series.

Quote from StorageReview:

The Dell Storage SCv2000 Series is a customer-inspired series of entry-level storage arrays that offer same common management and several of the core features as higher-end Dell SC Series arrays, such as the SC4020. According to Dell, the SCv2000 Series offers the “best performance and protection in its class with integrated data protection to support specialized projects, database and test environments, or simple storage consolidation.” The new arrays enable customers to standardize on a common platform, saving time and money. The SCv2000 Series comes in three models with expansion options: the SCv2000, SCv2020, and SCv2080

Benefits include:

• High performance at an affordable price – The arrays deliver best-in-class performance in a single, affordable 2U enclosure. Feature-rich options include proven data protection features, RAID tiering to optimize capacity, thin provisioning, flash support, data-migration services, and multi-protocol connectivity. Granular data protection allows up to 2,000 snapshots and 500 replications.
• Integrated data protection- Remote Instant Replay, Local Instant Replays and Replay Manager along with RAID tiering that optimizes SAN capacity. Tight integration with common application environments, such as Microsoft and VMware, help to simplify virtualized data centers, allowing local and remote data protection features to take consistent snapshots of virtual machines without sacrificing performance.
• Future flexibility with Storage Center – Customers can gain more value from existing investments with data migration to higher-tier Dell Storage SC4000 and SC8000 Series arrays. The SCv2000 Series supports today’s needs and future growth as the arrays can be managed with the same, single user interface as other SC Series arrays. Customers can scale capacity when needed with the benefit of no capacity licensing and choose from a broad range of hard drives and SSDs, configured for a variety of applications.
