SanDisk Announces Release of ULLtraDIMM, The Industry’s First Flash-Based Ultra-Low Latency Storage Device

SanDisk Corporation (NASDAQ: SNDK), a global leader in flash storage solutions, today announced that its ULLtraDIMM™ Solid State Drive (SSD), the industry’s first enterprise-class, ultra-low latency, memory channel storage solution, is now shipping for qualification with select enterprise servers. The addition of flash technology on the DRAM memory channel expands the growing penetration of flash storage technology in enterprise data centers, and complements SanDisk’s existing flash-based server hardware and software storage solutions.

The award-winning SanDisk ULLtraDIMM SSD can be integrated into an existing DIMM slot.1 This ensures ultra-low latency in business applications and results in improved application response times. Additional ULLtraDIMM SSDs can also be added to available DIMM slots, scaling performance and capacity without impacting latency. This creates new opportunities for server system designs to support use cases that require extremely fast storage, such as High-Frequency Trading (HFT), VDI, transaction processing, virtualization and cloud computing.

“The SanDisk ULLtraDIMM SSD was designed to expand the reach of ultra-low latency flash storage throughout the data center and scale to meet the requirements of any enterprise application, no matter how bandwidth or capacity intensive,” said John Scaramuzzo, senior vice president and general manager, Enterprise Storage Solutions at SanDisk. “The ULLtraDIMM SSD’s linear performance scalability and innovative DIMM form factor allow organizations to deploy flash as their application requirements change, without requiring significant infrastructure investment.”

SanDisk’s ULLtraDIMM SSD will be used by IBM under the eXFlash DIMM brand name. IBM recently announced that the eXFlash DIMM is an option for its System x3850 and x3950 X6 servers providing up to 12.8TB of flash capacity2. IBM tested the solution under a variety of enterprise workloads and end-user scenarios. These early benchmarks showed that the eXFlash DIMM SSD achieved 5-10 microsecond write latency—the lowest in the industry.

Gartner indicates “that the advent of big data use cases is just one dynamic compounding the challenges of managing data growth, and organizations face massive volumes of information and new content types that require variable storage, security, protection and access methods.”3 This data growth coupled with end-users’ demand for instant access to information is spurring the need for a revolution in how chief information officers (CIOs) leverage storage to manage requirements while reducing total cost of ownership (TCO).

Recently announced Azure Data Lake addresses the big data 3V challenges; volume, velocity and variety. It is one more storage feature in addition to blobs and SQL Azure database. Azure Data Lake (should have been Azure Data Ocean IMHO) is really omnipotent. Just look at the key capabilities of Azure Data Lake:

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud wit...
Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it. They can't only rely on the cloud to collect and utilize this data because many applications still require dedicated infrastructure for security, redundancy, performance, etc. In his session at 17th Cloud Expo, Emil Sayegh, CEO of Codero Hosting, will discuss how in order to resolve the inherent issues, companies need to combine dedicated a...
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds.
