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.
