SOLVES I/O SCALE &
BOTTLENECK CHALLENGES

PRODUCT FAMILY
DDN’s Infinite Memory Engine® (IME®) is a scale-out, software-defined, flash storage platform that streamlines the data path for application I/O. IME interfaces directly to applications and secures I/O via a data path that eliminates file system bottlenecks. With IME, architects can realize true flash-cache economics with a storage architecture that separates capacity from performance.
Several key factors, both technological and commercial are creating demand for a new approach to high performance I/O. New non-volatile memory (NVM) device technologies are proliferating and media capacities are increasing rapidly. Diverse many-core processor strategies are pushing higher I/O volumes and more demanding I/O profiles. A new generation of high-business-value markets are taking advantage of analytics and machine learning and further stressing performance boundaries. Traditional file systems only crudely manage flash at scale whereas HDD performance degrades as concurrency increases. IME introduces a new layer, above the file system that:
IME delivers predictable job performance, provides faster computation against data sets too large to fit in memory, accelerates I/O-intensive applications and provides a safe, cost and space-efficient landing space for bursty data.
For environments that want the maximum deployment flexibility, IME is available as software-only. IME software-only is ideal for those environments with IT-based limitations on supported hardware; that want the flexibility to repurpose existing hardware; and that have open-platform requirements. Most importantly, whether you decide to use IME240, or software-only, IME is the industry’s only flash-native cache that is not locked into a specific server or storage hardware vendor. With DDN’s IME, the choice is yours.
For an integrated appliance, DDN offers the IME140™ and IME240™. The IME240 is built on a best-of-breed 2U commodity storage server that delivers over 20GB/s of bandwidth and over 1M IOPs direct to applications. IME240 has up to 23 NVMe SSD drives for data and flexible N+K erasure coding. The IME140 supports extreme file performance in a small 1U flash data appliance. Each appliance can deliver more than 11GB/s write and 20GB/s read throughputs and more than 1M file IOPs (read and write). Starting with a resilient solution as small as 4 units, the IME140 allows organizations to cost-effectively scale performance independent of amount of capacity required.
