SSD AND DISK, EMBEDDED
To address the comprehensive needs of HPC environments, the revolutionary DDN SFA14KX Hybrid and Hyper-Converged Solution delivers 60GB/s, 3.5 Million IOPs and industry-leading density in a single 4U appliance.
DATA GROWTH IS A CHALLENGE AND A STRATEGIC OPPORTUNITY
One of the biggest continuous challenges in HPC is the ability to manage and take advantage of huge data growth. Compute performance increases at a much faster rate than storage media performance while data is growing faster than compute, making storage the most strategic component of the high performance data center performance.
Technologies have only provided help in at least one dimension: access, performance or growth. New flash products raise the performance of an individual drive. Higher performance networks will drive data into and out of compute faster. New technologies like burst buffers will speed applications. But each of these alleviates only one part of the problem.
INTRODUCING THE MOST ADVANCED AND COMPLETE HPC STORAGE PLATFORM
By integrating the latest high-performance technologies from silicon, to interconnect, memory and storage, the SFA14KX changes the future of HPC architecture design. The revolutionary DDN SFA14KX is a high-performance block storage and hyper-converged platform that accelerates them with DDN high-performance software features and balances them to deliver the fastest performance at the lowest latency.
Intelligent caching and full bandwidth infrastructure delivers maximum advantage from SAS based SSDs, NVME* and HDDs. Non-blocking internal PCI-e and 12Gb SAS fabrics ensure fast, low latency data access while high performance networking connectivity options like InifiniBand™, Intel® Omni-Path, FC, Ethernet significantly reduce the number of ports, cables and network devices lowering acquisition and administrative costs.
SFA14KX delivers an unmatched number of SSD and spinning drives in the least amount of space, making it one of the most dense storage solutions on the market. This extreme level of density makes the SFA14KX ideal for data centers with limited space, or any high-performance environment needing to expand capacity without adding the complexity of many appliances to manage and the cost of powering and cooling a large number of controllers.
At SC17, Ryan Weiss of DDN introduces Declustered RAID (DCR) as part of the new SFAOS release, common RAID pain points and how SFA DCR dramatically reduces time to regain full redundancy following a disk failure.
Delivers more than 3.5 million IOPS, 60GB/sec and the highest density storage in 4U available in the industry today. Ingests, analyzes and distributes data at top speeds to deliver results many times faster than competing systems.
Delivers up to 9PB in a single rack and up to 16X the per rack performance of its closest competitor. The decreased data center footprint reduces both cost and complexity
Handles small, large and mixed IO workloads that would cripple most systems built for high performance.
The only hardware platform that hosts applications on an embedded PCI-e fabric to deliver up to 10 times the latency reduction from application to memory to storage
Delivers up to 10X the performance of previous SFA generations and up to 40X the performance of competing platforms with more than 5X the IOPS of DDN’s closest competitor.
Scales up or scales out to allow users to buy only what they need, to optimize performance, density or both
Interconnect options include InfiniBand, Omni-Path, Fibre Channel and Ethernet, and leverages NVMe memory along with Solid State and hard disk storage
With utmost simplicity at scale, the solution’s convergence benefits reduce administration costs up to 70%
SFA Declustered RAID (DCR) significantly improves rebuild performance. 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 enable 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.
