Different Types Of Raid Arrays

With the increasing of storage products in the market, the backend storage system becomes the core and key of enterprise business system. Inevitably, companies are more concerned with data security. Generally speaking, there are four ways we can solve data security problems in stored procedures, offsite backup can avoid the loss of data in the event of natural disasters, and RAID (redundant array of independent disks) can reduce the damage of disk parts; Reduce downtime losses. These technologies are the security of data, while the protection of data is stored ...

With the advent of the HD era, the ancient storage mode has been unable to meet the needs of high-definition, more and more enterprise customers video communications demand for explosive growth, coupled with the strong promotion of equipment manufacturers, video surveillance will be used in the field of cloud storage this topic became hot. 　　The new generation of information technology, represented by cloud computing, Internet of Things and mobile interconnection, has become a strategic emerging industry and will be supported and developed by the State in the 35 period. In the 2010 China International Social Security Products Expo, facing the growing demand for security storage, as the leading domestic ...

Cloud computing (Cloud Computing) is an internet-based Super computing model in which thousands of computers and servers are connected to a cloud of computers in remote data centers. The user uses the computer, the notebook, the handset and so on the way to pick up the data center, according to own demand carries on the computation. There is still no universally agreed definition of cloud computing. Combined with the above definition, we can sum up some essential features of cloud computing, that is, distributed computing and storage characteristics, high scalability, user-friendly, good management. 1 Cloud storage schema orange as storage node (Storag ...)

DAS, Nas, and San three storage for storage, many people still stay on the simple hard disk, memory, with the rapid development of the network era, storage technology constantly updated, storage has long been in the hard disk technology based on the rapid development. 　　Now that enterprise-class storage technology is constantly pouring into the marketplace, making it difficult for users to perceive professional terminology, such as networked storage, virtual storage, cloud storage, data deduplication, archiving technology, and so on, are these technologies confusing? Although mastering these terms doesn't seem practical to most people ...

"51CTO" "There is no panacea for disaster recovery problems," said Jack Bailey, engineering manager at Cloud computing provider Iland. "Whenever an outage horror story occupies the headlines of major media, managers often respond subconsciously, hoping to deploy the fastest disaster recovery product immediately," he said. "However, there are differences in the specifics of each business and its location, so rushing to choose a solution before a thorough assessment of a given condition often leads to two major sequelae-either too much."

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...
