To make the most of.

IT companies often fail to properly use the monitoring tools of the virtualized environment. There is a trend to continue to use the same monitoring tools that were used in traditional data centers, but these tools are not sufficient to monitor traffic between virtual servers.

All indications are that 10,000 trillion and 40,000 gigabit Ethernet will be implemented in the coming years. For example, it discusses the enhanced architecture research and development that Cisco continued to the end of 2011, from the server network interface to the core network, and referred to Cisco's fiber-optic switch route map based on commercial silicon, code-named "Gravel Machine". There are many interesting predictions, such as 10GB Ethernet and GB Ethernet. Expect to see a large number of server boards that support 10GB. At the beginning of the year, you can even see many 10GB Ethernet interface motherboards. All this means that we are already in the application of GB ...

Virtualized server environments pose a small challenge to storage managers, at least to maintain monitoring of data storage and virtual server connections. There are storage management products available on the market that can be applied to this new environment, allowing users to continuously monitor the virtual servers, the applications running on the server, and the storage resources they occupy. Independent application features a typical chimney-style architecture for specific applications in each datacenter. Each chimney-style architecture corresponds to a dedicated administrative group and is equipped with a team that is responsible for specific resources in the datacenter, such as networks, servers, storage systems, and virtual tiers. And every ...

Private Cloud is the latest attempt by data centers to improve efficiency and enhance hardware and software flexibility. 　　The idea is to create a pool of computing resources, storage, and network resources and manage them from a central software control point, rather than manually implementing the relevant regulations for all infrastructure, monitoring and reconfiguring management. Predictably, the public cloud service provider itself is the most experienced in designing and running shared infrastructure. Amazon, Google, Microsoft, Salesforce will not use the old traditional let static infrastructure dedicated to individual application of the method to pipe ...

Although it seems that we have listened to unified storage for a long time, it is relatively new-meaning we are still accepting the early stages of the cycle. One thing is clear, however, that unified or multi-protocol storage has a very attractive value advantage. In a unified storage environment, data storage becomes a shared pool of resources to store block or file data and configure it according to application requirements. So it's not surprising that users are very interested in implementing a unified storage platform. In a recent survey of 306 IT professionals with storage planning or decision-making responsibilities, ESG (Ente).

Nowadays, it is imperative for many enterprises to deploy server virtualization and eventually convert it into a virtual cloud. In many ways, server virtualization and cloud computing are mutually contradictory. In theory, companies and their IT departments can integrate the two to achieve symbiosis and improve the efficiency of the enterprise. The goal is to centralize data center resources and deliver applications and services effectively when users need or have business requirements. As long as properly deployed and properly managed, consolidating server virtualization technologies in private cloud systems can be achieved by consolidating network resources, reducing power consumption and facility costs, and reducing the cost of containing ...
