Software Raid Configuration

Using Fedora Linux To configure RAID requires careful follow some steps. In the example of this tutorial, you will use a system to configure RAID5, whose hard disk is divided into three areas in advance. The partitions used are as follows:/DEV/HDE1/DEV/HDF2/DEV/HDG1 Please make sure that the steps listed below can be adapted to your particular environment. RAID partitions First, you have to delimit two or more partitions, each on a separate disk. If you build RAID 0 or RAID 5, each ...

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 ...

For some enterprise users, the procurement server is often vulnerable to budget bottlenecks, causing the server to remain only at the "available" level. In fact, if you pay a little more for the budget and upgrade your management tools and redundancy, the security of the entire server will improve a lot. 　　After all, the server is carrying a number of key applications, stable operation is also very important. Lenovo Thinkserver RD630 S2609 4/2*1throd:29000 Yuan If this year's domestic brands in the highest exposure, I am afraid that the number of Lenovo new release ...

Simply put, a cluster (cluster) is a group of computers that provide users with a set of network resources as a whole. These individual computer systems are the nodes (node) of the cluster. An ideal cluster is that the user never realizes the nodes at the bottom of the cluster system, in their view, the cluster is a system, not multiple computer systems.     And the administrators of the cluster system can add and revise the nodes of the cluster system at will. Below on the server commonly used three cluster software to do a comparative analysis of the introduction: 1 ...

Absrtact: In the current IT industry, "cloud computing" has become almost a popular element, many hardware and software manufacturers began to transfer their products to the cloud, or put forward in the cloud architecture in the direction of development.  The role of "cloud storage", which belongs to the storage area, is not yet clear. Keywords: cloud computing cloud storage technology in the current IT industry, "cloud computing" has become almost a popular element, many hardware and software manufacturers began to gradually transfer its products to the cloud, or proposed in the cloud ...

This article will introduce the choice of enterprise 1U Rack Server to understand the key factors, compared with the internal characteristics of a variety of 1U servers, expansion capabilities and management functions, and to provide buyers with a current mainstream 1U server specifications list. Processors are often the primary consideration in many of the most powerful 1U servers. Today's 1U servers can typically support 1~2 CPUs, such as the Intel Xeon 5500 or Xeon 5600 series. Service based on AMD processors ...

Simple and reliable hp StorageWorks X1600 G2 2011 Global Data volume will reach 1.8ZB, indicating that humans will enter the ZB, YB era (1YB=1000ZB=10^24GB). The advent of the cloud computing era has accelerated the explosion of data. How do we deal with the two major challenges to data processing and storage? What are the popular servers and storage products available today that meet the needs of the current and future time? To this end, before the arrival of the 11 Golden Week, before people are ready to work ...

Most storage managers agree that storage costs are not just the price of buying physical hardware. IT managers often add maintenance costs and the cost of running and managing storage for administrators. 　　In fact, there are more components to the true cost of storage, and determining the true cost of storage systems requires determining the cost of x capacity to provide a level of Y-level performance to an application. Let's take a look at the cost of providing capacity, for example, if you have an application that requires a net usable capacity of terabytes, how much storage do you need to actually buy to ensure that terabytes of storage? Obviously ...

It companies around the world are working to virtualize and automate data centers in the hope of helping their business achieve higher value and lower costs, delivering new data-driven services faster and more efficiently. Intel (R) Xeon (TM) processor-based servers provide the foundation for this innovation. These servers account for the vast majority of all servers in the current virtualization center and cloud environment, and can support most of the most high-performance workstations. Performance improvement up to 35% Intel Xeon Processor e5-2600 ...

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 ...
