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 ...

The rapid development of network technology, so that enterprises and institutions local area network access to the Internet to share resources more and more, for the most part, DDN dedicated line with its stable performance, the advantages of good expansion into a common way, DDN way of connection in the hardware requirements is simple, Only one router (router) and proxy server (proxy server) is required, but the configuration of the system is a tricky issue for many network administrators.

When we talk about production environments, each administrator should consider all possible single points of failure (SPOF) and resilience in the schema. Here, we will explore the VIOS and LPAR networks, which eliminates the most likely SPOF of the network, providing a separate network that can quickly communicate with the backup server to access applications and databases. This architecture has been widely used, where users can access the server 24x7, and administrators can back up data without affecting user bandwidth. Figure 1. Schema diagram in this architecture, ...
