Citrix Xenserver High Availability

Today's demand for data centers is solid and effective, and this should be done first by "reasonable use". While idle resources are a waste of money for an environment. But if you fail to make a reasonable resource allocation to the frequently used data center, it will lead to a dangerous scene. A single hardware failure may cause other physical hosts to fail. The challenge for IT managers is to use and manage computing resources across the entire environment (usually including physical, virtual, and cloud resources). This article will discuss resource planning and problem mitigation as a means to achieve the goal of resource optimization. We will also ...

A few days ago, a very small number of cloud computing vendors can provide a flexible, scalable, has been available for enterprise practical application of the complete cloud computing products or services. Citrix's new product for cloud computing allows enterprise users to create a new infrastructure for cloud computing, and can be transferred to others for use. Using the products in the Citrix Systems Company Cloud Suite, IT administrators can manage virtual machine management programs, desktop delivery, federated identities, and user profiles.

A, virtualization virtualization refers to the ability to simulate multiple virtual machines on the same physical machine. Each virtual machine has a separate processor, memory, hard disk, and network interface logically. The use of virtualization technology can improve the utilization of hardware resources, so that multiple applications can run on the same physical machine with each other isolated operating environment. There are also different levels of virtualization, such as virtualization at the hardware level and virtualization at the software level. Hardware virtualization refers to the simulation of hardware to obtain a similar to the real computer environment, you can run a complete operating system. In the hardware virtual ...

Fuelled by recent announcements from VMware and other big manufacturers, the hybrid cloud has become increasingly appealing to the public. The hybrid cloud integrates the public external cloud and the internal private "cloud" (which is now equivalent to the traditional internal IT environment) into more functional solutions. The "secret" of mixed clouds is the technology of connecting in the middle. 　　To more efficiently connect the computing and storage environments of external clouds and internal clouds, hybrid cloud solutions need to provide enterprise-class security, manageability across cloud platforms, portability of load/data, and interoperability. Mixed clouds have a lot of ...

2011, if the industry is talking about the most, the most attention to a word, not "cloud" mo. Cloud computing after several years of brewing and development is moving from theory to practice.　　　　Cloud computing is rising from perceptual knowledge to rational knowledge, not a fad to hype a concept, arguing about the definition of cloud computing, more focused on how to land the cloud. Security experts from McAfee recently released their network surveys commissioned by Boko and McAfee. There are 100 it majors involved in the survey ...

The original Intel platform Test private Cloud architect, now an IT company Cloud product leader, Sina Weibo, "cloud computing Private Cloud research" blogger Eric Li from his own practical experience, summed up the following about cloud computing 5 of atypical thinking. 1. Do not put eggs in one basket: SmugMug was the "Survivor" of Amazon's cloud failure last month, and it succeeded in averting disaster, first because it did not put all the business in a availability Zone (AZ), and the second was that it did not put all the ...

The benefits of server virtualization now are significant, and it is a natural choice to implement the technology. First, server virtualization makes more use of computing resources than physical servers, because you can run many different virtual servers on a single physical host. In fact, the number of common server instances that a single current server can handle at the same time can be a surprise to you. Another great advantage of server virtualization is the ability to transfer a running virtual server between multiple physical hosts, balancing the load and facilitating maintenance. You can also use the virtual server snapshot, in the change ...
