What is DDN SFA18K?
With up to 3.2 million IOPs and 90 GB/s from a single 4U appliance, the SFA18K is the fastest storage solution on the market today and offers the highest density available with the ability to generate an unmatched number of flash (NVMe and SAS) devices and swivel units in the smallest amount of space. This extreme level of density makes SFA18K ideal for data centers with limited space or any high-performance environment that wants to expand capacity without adding the complexity of many appliances to be managed and the cost of feeding and cooling a large number of controllers.
Simple to scale
Converged hardware significantly reduces costs and complexity with a smaller number of ports, cables, and network devices.
Higher density
The SFA18K delivers unprecedented density per rack unit per system and delivers up to 13 PB in a single rack.
Increased protection
Scalable, disqualified RAID offers higher rebuild times, increased data availability, and protection for new large-format drives.
Faster Performance
- 3.2 million IOPS, 90 GB/s in 4U
- Eliminates the need to buy flash arrays forward from your rotating disc
- Highly optimized Internal PCIe mesh and 12Gb back-end SAS meshes ensure fast, low latency access to data
- The latest network connectivity options for current environment support and future protection
- Unique built-in application options for ease of management and lower latency
Hyperconverged Platform Accelerates and Balances New Technology
The revolutionary SFA18K is today's high-performance, hyper-converged storage platform with an architecture that harnesses the power of the latest technologies, accelerates them with DDN's high-performance software capabilities, and balances them for faster performance at the lowest latency.
Configurations Start On Small Scale and On Demand
SFA18K building blocks start at hundreds of terabytes and scale to more than 25 petabytes. Select the building block size that best suits your requirements profile through IOPs, bandwidth, capacity, and number of devices under management. The performance and density of the SFA18K enable a smaller solution footprint and with a lower inverter controller-to-inverter ratio, energy and cooling efficiency is increased while reducing administrative complexity and cost.
