What is it?
Software Defined Storage ("SDS") refers to the virtualization of storage systems, whereby the underlying storage hardware is abstracted from the storage software that manages it. SDS can be an element with a Software Defined Data Center or it can also function as a stand-alone technology. The software enabling the storage-defined storage environment may also provide policy management for features such as data de-duplication, replication, thin provisioning, snapshots and backup.
Why do you need it?
Since a Software Defined Storage system virtualizes and abstracts the hardware on which it is based, capacity and performance can more easily be added or upgraded, especially without causing downtime to the storage system. The hardware can also be distributed over different locations. Storage capacity of different devices and locations can be combined into a central resource "pool", which can be utilized as needed.
An SDS platform is also designed to work on commodity x86 hardware, allowing flexibility to be used on a range of different hardware types and systems and ensuring there is no vendor "lock-in" – previous hardware based storage systems were very vendor specific, and the user had very little control over the cost and capacity of purchasing and upgrading this hardware. Many SDS platforms are also based on open source software, which are continuously being refined and updated by a large community of users, and also ensure wide compatibility with different hardware, OS and other software programs, and feature open programmable APIs for comprehensive integration and workflow automation with other applications.
Who needs it?
Software Defined Storage is ideal to be used as part of a broader virtualized computing environment, such as an on-premises private cloud. Since SDS virtualizes physical resources and contains features such as thin provisioning and de-duplication as well as being highly scalable (users can simply "add-on" capacity as needed and don’t need to invest in extra unneeded capacity months or years ahead of time) , it is excellent at maximizing resource utilization efficiency while minimizing the cost of installation and expanding capacity. Therefore, organizations that wish to reduce both their capital and operational expenses are encouraged to look at a SDS system to replace their legacy storage infrastructure.
How is GIGABYTE helpful?
GIGABYTE is currently collaborating with several software defined storage platform vendors, including Bigtera (VirtualStor) and Alcestor / Tuxera (MooseFS), offering a range of turnkey storage appliances (combing SDS software as well as GIGABYTE server hardware) to meet a variety of different performance, capacity and cost requirements.
Cluster Computing: An Advanced Form of Distributed Computing
Cluster computing is a form of distributed computing that is similar to parallel or grid computing, but categorized in a class of its own because of its many advantages, such as high availability, load balancing, and HPC. GIGABYTE Technology, an industry leader in high-performance servers, presents this tech guide to help you learn about cluster computing. We also recommend GIGABYTE servers that can help you benefit from cluster computing.
What is a Server? A Tech Guide by GIGABYTE
In the modern age, we enjoy an incredible amount of computing power—not because of any device that we own, but because of the servers we are connected to. They handle all our myriad requests, whether it is to send an email, play a game, or find a restaurant. They are the inventions that make our intrinsically connected age of digital information possible. But what, exactly, is a server? GIGABYTE Technology, an industry leader in high-performance servers, presents our latest Tech Guide. We delve into what a server is, how it works, and what exciting new breakthroughs GIGABYTE has made in the field of server solutions.
Storage Systems are Extremely Important for Business Continuity
In an era of increasing technological advancement, an important issue for enterprises and the key to maintaining business continuity is how to prevent important data from being accidentally lost due to human error, deliberately deleted or even stolen.
