Problem IBM's many servers have two special RAID architectures, raid5e and Raid5ee, what are the advantages of these two raid architectures, and are these two structures worth recommending from a professional RAID data recovery perspective? First to paste a paragraph on raid5e and Raid5ee introduction: RAID5E Raid5ee Raid5e and Raid5ee are frequently mentioned technologies that support two disk failures, and IBM's storage systems use this RAID technology extensively to achieve dual-disk fau

Part I: Data recovery programme "User Unit" a pharmaceutical company "Fault description" IBM X3850 Server, 5 73G SAS hard Drive, where 4 pieces make up one RAID5, the other as a hot spare (hot-spare), 3rd disk is already offline, but the hot spare is not automatically activated rebuild (unexplained), after 2nd disk offline, RAID crashes. Operating system for Linux Redhat 5.3, Application systems for the architecture of an Oracle OA, the data is im

of writes, one at a time, and the other to stop the read action to ensure the consistency of the data. Moreover, the more distributed servers, the more write conflicts may result, and the longer the database locks up, thus causing the bottleneck of the database. Cooper Information Technology director Lin Yin said: "IDS 11 new architecture just solves this problem." "writes data to the primary server, avoids write conflicts, provides only secondary servers for queries, and provides continuous s

A package is a collection of software installation files, configuration files, and metadata that can be deployed on a virtual machine instance. In the last article in this series, the author describes three mechanisms for capturing custom mirrors by using ICCT to create mirrors, and for manually adding dependencies between mirrors and packages by updating the semantic topology file. ICCT performs bookkeeping tasks and provides a step-by-step process and a graphical UI to easily create packages,

Introduction to RTC The IBM Rational Team Concert (RTC), as a software collaborative development tool, is gradually being used in the production of large projects, maintaining a large project organization and methodically managing each development task, thus laying a solid foundation for creating high-quality software products. The RTC provides an integrated environment throughout the development process, including requirements definition, iteration

Background of writing this article As smartphone usage grows, more and more web-based applications are starting to provide the ability to access from mobile clients, whether the client is a browser or a native application. In both cases, these clients can use HTTP as a network protocol and, theoretically, they can be tested using the primary load test tools. On the other hand, most of the current available products, including IBM Rational performance

zone. Typically, when you use static routing, you specify the location of the resource in the resource definition that is installed. Sample Scenarios A virtual I/O server located on a private network (IP-192.168.10.101) An IBM AIX server has two network adapters: one on the private network, the other on the VIOS, and the other on the public network. (Private network IP-192.168.10.32 and public network IP-9.3.129.14) AIX clients on public network

both racks. Applications deployed across two systems Let's take a detailed description of the pureapplication System in this setting. Because we focus on the Web application, we need a Web server, an application server, and the application itself, which are arranged in a topology that supports high availability. This is useful for discussing practical applications, so let's take tradelite as an example. Sample WEB Application and database Tradelite is an

In many scenarios, using a network to install PowerLinux is a good, even necessary choice, for example, to install a very multiple partition powerlinux, or to install a partition that does not have a physical optical drive or a virtual CD drive to install. Two kinds of powerlinux, whether Red Hat or SUSE, have their own network installation methods, but one is the configuration process is more complex, the other is the two kinds of Linux to do network installation of different methods, to the P

Brief introduction The previous articles in this series have focused on how to deploy the application to IBM pureapplication System. After you deploy your application, you need to consider how your application stores and accesses the data. The relational database management system provides a standard data storage and retrieval interface, an advanced security model around data access, and concurrent support for multiple users accessing stored data con
