DDN SFA18K: The World’s Fastest Block Storage with Embedded Application Option
At up to 3.2 million IOPs and 90GB/sec from a single 4U appliance, the SFA18K® is the fastest storage solution in the industry today, and delivers the highest density available with the ability to drive an unmatched number of flash (NVMe and SAS) devices and spinning drives in the least amount of space. This extreme level of density makes the SFA18K ideal for data centers with limited space, or any high-performance environment wanting to be able to expand capacity without adding the complexity of many appliances to manage and the cost of powering and cooling a large number of controllers.
SIMPLEST AT SCALE
Converged hardware significantly reduces costs and complexity with a lower number of ports, cables, and network devices.
SFA18K delivers unprecedented density per rack unit, per system and provides up to 13PB in a single rack
Scalable, declustered RAID provides superior rebuild times, higher data availability, and protection for new large format drives
- 3.2 million IOPS, 90GB/s in 4U
- Eliminates need to buy flash arrays to front your spinning disk
- Highly-optimized Internal PCIe fabric and 12Gb back-end SAS fabrics ensure fast, low latency data access
- Latest networking connectivity options for current environment support and future-proofing
- Unique embedded application options for ease-of-management and lower latency
Hyper-Converged Platform Accelerates and Balances New Technology
The revolutionary SFA18K is the highest performance block storage and hyper-converged platform in the industry today with an architecture that harnesses the power of the latest technologies, accelerates them with DDN high-performance software features and balances them to deliver the fastest performance with the lowest latency.
DDN Unique Software-Defined Capabilities Deliver Optimal Utilization
SFA Declustered RAID (DCR) significantly improves rebuild performance by increasing the pool of disks which participate in backing a redundancy group, allowing reading and writing to many times the RAID member count (eg 10 disks in 8+2). DCR allows for the striping of data across a much larger set of physical disks than was previously available in traditional RAID and greatly increasing the parallelism of drive rebuilds. It is this parallel process that enables rebuilds to run much faster than traditional RAID. In addition to decreasing recovery times, DCR can also result in increased storage efficiency and higher IOPs performance.
Configurations Start Small and Scale on Demand
SFA18K building blocks start in the hundreds of terabytes and scale to over 25 petabytes. Select the building block size best suits your requirements profile across IOPs, streaming bandwidth, capacity and number of devices under management. The SFA18K performance and density enables a smaller solution footprint and with a lower controller-to-drive ratio, power and cooling efficiency are increased, while reducing administrative complexity and cost.
