Software-Defined Storage

by: Yih-Farn Robin Chen,

Cloud storage for both consumers and enterprises is growing at a phenomenal rate, fueled by the growth in Big Data, Mobile, and Social Networks. It is becoming a major cost component in the cloud infrastructure and any Web-scale cloud services today. While raw storage is cheap, the performance and data durability requirements of cloud storage frequently dictate sophisticated, multi-tier, geo-distributed and managed storage solutions.

Traditional storage systems use dedicated storage hardware and networking to guarantee that the storage QoS requirements such as throughput, latency, IOPS, and reliability are preserved.  Unfortunately, these dedicated resources are frequently underutilized.   Cloud computing promises efficient resource utilization by allowing multiple tenants to share the underlying networking, computing, and storage infrastructure, but it is difficult to provide end-to-end storage QoS guarantees to individual tenants due to the noisy neighbor problem.

Winner of the AT&T SDN Network Design Challenge


The AT&T SDN Network Design Challenge provided an opportunity for academia to innovate at scale and work with a realistic, carrier-grade network to improve routing and network utilization.

Cornell University has been named winner of  the first ever  AT&T SDN Network Design Challenge.

AT&T Announces ECOMP


AT&T recently revealed details and a white paper describing ECOMP – Enhanced Control, Orchestration, Management and Policy. ECOMP is AT&T's vision for automating cloud-based network services and infrastructure; we see it as the engine behind our software-centric network.

2016 AT&T Research Academic Summit


AT&T is transitioning its carrier grade multi-service network into a software-defined intelligent SDN/cloud-based infrastructure. The AT&T 2016 Research Academic Summit took place on March 31 - April1, 2016 in Bedminster, NJ. This workshop aimed to introduce students to the unique technical challenges AT&T faces, and to enhance AT&T / academic collaborations.

Software Defined Storage


Every minute, new videos, pictures, phone calls and emails are born. Let that soak in for a second. Data is increasing even as you read this sentence. It is increasing faster than it used to. In fact, the world created 90% of its data in the past two years.

As the volume of data explodes, so does the cost of storing and maintaining it. As companies become more data driven, cost effective data management is critical to business success.


Mobile Call Recording


Time is money. For the banking industry, it’s their business. Brokers need the flexibility to take orders while on the fly. Mobility is critical for banks and financial services organizations.

But it’s not as simple as taking an order. Regulations require verification for transactions like a stock trade. And sometimes an order comes in when brokers are not at their desk. That’s why financial companies need a way to record these transactions

Service Quality Management


The Service Quality Management program at AT&T is improving the network experience for our customers. This program transforms how we manage our network.

Researchers at AT&T Labs work with our network engineers to learn about the experiences of our customers. They try to see the network the way customers see it.
