What will you do in 4U? Providing DDN's legendary multiples of performance, capacity and reliability, the S2A6620 is the ultra-dense, affordable storage solution designed for business. Simplify and consolidate many of your lower performing and space inefficient storage servers and enclosures into this single, 4U high performance appliance, this is the business enabling storage powerhouse.
Stay ahead of growing performance and capacity requirements with the most efficient mid-range appliance platform. Each S2A6620 delivers leading in-class performance and accommodates sixty drives in just 4U. To scale capacity, simply add an additional enclosure to bring your total to 120 drives (that's up to 360TB) in only 8U.
Robust end-to end data protection and availability features, a simple cost-effective platform and extreme value are why so many S2A6620 systems are at work today in business production environments worldwide.
In today's environment of extreme data growth and flat budgets, there is a way to lower costs, simplify your infrastructure and maximize application performance, scalability and uninterrupted data access. The S2A6620 mid-range storage appliance with Realtime Adaptive Cache Technology (REACTTM) delivers balanced throughput and IOPS performance in the industry's highest density and energy efficient platform. Featuring up to 60 drives in just 4U of rack space, this high performance storage appliance delivers up to 335,000 IOPS from its 12GB of mirrored, battery backed-up cache, and 2GB/s of sustained bandwidth for large file throughput. Scaling to 120 drives with the addition of a single 4U expansion module, and the ability to combine SATA, SAS and SSD drives within a single appliance, the S2A6620 is a differentiated solution that is perfect for diverse workloads and a wide range of requirements.
Exceptional per-drive performance reduces the number of disks needed to meet growing performance and capacity demands - lowering both acquisition and operational costs. Intermixing high-performance SSD and SAS drives with high-capacity SATA drives places data on the appropriate performance and cost-effective drive technology. DirectProtect™ enables the appliance to manage large pools of SATA storage with enterprise-class performance, reliability and data integrity. This innovative, self-healing technology provides on-the-fly error detection and correction, so applications receive the only the correct data and minimizes the need for lengthy drive rebuilds. Redundant, hot swappable components, automated failover features, and RAID 6 deliver end-to end data protection and availability.
Increase productivity with leading in-class performance that removes storage bottlenecks
Enables more applications to thrive on a single system with the support of high performance and high capacity drive types
Reduce floor space, management, power and cooling by collapsing multiple systems into an ultra-dense, highly efficient platform
Housing 60 drives in just 4U enables your data center to scale growth much more cost and space efficiently than other commercial or white-box solutions
Seamlessly integrates into new or existing infrastuctures, powerful Web based GUI, CLI, CNMP and email alert options provide for simple, flexible administration
Makes large SATA pools with high duty-cycles reliable at half the price of SAS or FC drives

According to IDC, data is poised to grow 40x over the next 10 years. How will you stay ahead of the demand?
Deploying S2A6620 means the fewest number of systems to buy, support, power and manage as you scale your environment to hundreds to terabytes and beyond.
Highly flexible, the S2A6620 supports multiple RAID levels and configurations. Depending upon which data protection scheme you select, you can start as small as 2 drives. The S2A6620 scales to 60 drives 4U and additional capacity can be added with the StogeScaler6000 enclosure supporting a total of 120 drives.
