Array Terminology

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 ...

This article describes the three main ways to deploy SSDs: Within the array, within the server, and with SSD devices. Each has its pros and cons, including latency issues and performance levels. Few new technologies can simultaneously improve performance while reducing costs. However, the very interesting technology of SSD achieves this goal. Most of the major storage vendors are beginning to provide a full range of SSD products. Solid-State storage drives can be deployed in three different forms: array-based SSD is generally considered for deployment in a storage area network;

As you will learn from this article, many users cannot today sort out the types of solid-state disks (SSD) on the market. This analysis of SSD architecture introduces the three main ways to deploy SSD: Inside the array, within the server, and using SSD devices. 　　Each has its pros and cons, including latency issues and performance levels. Few new technologies can simultaneously improve performance while reducing costs. However, the very interesting technology of SSD achieves this goal. Most of the major storage vendors are beginning to provide a full range of SSD products. ...

Over the past 15 years, there have been two debates in the field of display. Once before and after 2000, the color Picture tube (CRT) industry is facing the substitution crisis, the next mainstream direction is the plasma display (PDP) or the thin film transistor liquid crystal display (TFT-LCD)? There are very different voices in the industry. After more than 10 years of development, TFT-LCD has become the absolute mainstream of the display field. With the development of TFT-LCD and Electroluminescence (EL) technology, active organic light-emitting display (AMOLED) has been industrialized. In addition, the flexible display (flexible displa ...

This article originally envisioned a discussion of the current situation with SSD (solid-state drive) and disk array controller architecture--Some vendors may already have the preparation to let existing arrays handle more SSD. However, in the process of data acquisition of this subject, I heard many information about the company's cloud actions, and a growing number of manufacturers announced the beginning of cloud computing, and in their own IT products to increase the "cloud" function. So I temporarily decided not to talk about SSDs. For marketing means, this time the manufacturers are so broad ...

Search engine database, is a large and complex index database. 　　Do you want to know how your website pages are indexed by spiders, and what kind of page files do the search engines create for your page? 　　Please read carefully: 1 First, your page is "new", that is, original and false original. 　　2 Search engine Spiders crawl your site after reading page encoding, author, creation time and other attribute information. 　　3 Crawl website content information, and our common search engine crawl simulation tool can get out of text content. I wonder if I can post that ...

"The term 'gateway' has been deliberately avoided by start-up companies, and actually it started off pretty well and all of the essence of it was on its way to the cloud," said Arun Taneja, founder and principal consultant at Taneja Group. "To be honest, None of them knew what they wanted to be when they grew up and they did not find a use case. "As the cloud storage market continues to evolve, vendors are not just positioning themselves as putting data in the cloud, they see themselves as EMC A competitor to a company like NetApp. Some start-ups about three years ...

HBase terms in this article: column-oriented: Row column Group: Column families Column: Column unit: Cell Understanding HBase (an Open-source Google bigtable practical application) The biggest difficulty is what is HBase's data structure concept? First HBase is different from the general relational database, which is a database suitable for unstructured data storage. Another difference is that HBase is based on columns rather than on rows. Goo ...

The article uses a sample application to demonstrate DOM methods and properties and how to attach handlers to DOM events. The World Wide Web Consortium (WWW) has defined the Document Object Model (DOM) in different spec groups (DOM 1, Dom 2, and DOM level 3). The DOM represents HTML or XML as a tree that consists of nodes with different levels of properties and methods. Using the client language such as JavaScript, you can add, modify, and delete nodes in the tree ...

At present, blockchain technology is in an era of blooming and arguing, and various blockchains have emerged. Interoperability between blockchains has become a very important and urgent need.
