SNIA Whitepapers
This white paper will explore the need for a caching and buffering technology between DRAM and HDDs and why Flash memory can be used to fill this need. We will go on to look at various ways that Flash and HDDs can be combined in a computer storage hierarchy. These technologies to combine Flash memory and HDDs include hybrid HDDs, Flash on the computer motherboard, and a combination of Flash and HDD storage devices in the same computer – paired storage systems.
Solid state data storage is gaining significant acceptance today. Storage based on Ram Access Memory (RAM) and Flash chips instead of mechanical hard disk drives is earning much greater attention by meeting the market requirements for reliability, performance, and cost more effectively than ever before.

NAND Flash-based solid state storage (SSS) solutions, as they exist today, offer unparalleled performance combined with a level of data integrity and availability for mission-critical data that matches and potentially exceeds storage solutions based on mechanical, magnetic drives. Long associated with consumer electronics, NAND Flash has become a viable storage medium for commercial and governmental information systems, often referred to collectively as enterprise applications.
The SNIA Dictionary contains terms and definitions related to storage and other information technologies, and is the storage networking industry's most comprehensive attempt to date to arrive at a common body of terminology for the technologies it represents. The terms go through a rigorous technical review and approval process by the SNIA Technical Council to assure their accuracy.
The energy required to support data center IT operations is becoming a central concern worldwide. For some data centers, additional energy supply is simply not available, either due to finite power generation capacity in certain regions or the inability of the power distribution grid to accommodate more lines.

In April 2003, the Network File System (NFS) version 4 Protocol was ratified as an Internet standard, described in RFC-35301, which superseded NFS Version 3 (NFSv3, specified in RFC-18132). Since the ratification of NFSv4, further advances have been made to the standard, notably NFSv4.1 (as described in RFC-56613, ratified in January 2010) that includes several new features such as parallel NFS (pNFS).
Organisations of all types are trying to control costs and satisfy increasing demands at the same time— demands created by explosive data growth and ever-changing regulations. To address these challenges, storage industry professionals are turning to cloud computing and cloud storage solutions.

Today’s data explosion presents unprecedented challenges incorporating a wide range of application requirements such as database, transaction processing, data warehousing, imaging, integrated audio/video, real-time computing, and collaborative projects. For nearly a decade storage area networks (SANs) have become mainstays for companies looking to increase storage utilisation and manageability while reducing costs.
Many organisations, driven by the opportunities for significant cost-savings, are considering cloud computing and cloud storage solutions, which take advantage of Web-based technologies to allow scalable, virtualized IT resources to be provided as a service over the network. Not a new technology in itself, cloud computing is a new business model wrapped around existing technologies, such as server virtualization, to make the use of information technology resources more efficient.
