Crank up the performance, crank down the cost
All-new hardware platformDesigned 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 up to 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 workloadsBased 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 protectionDespite 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.
