Replacing your system with the four "Best excuses" of RHEL5"

Sometimes you cannot find enough reason to upgrade your system. For example, I cannot find enough reason to upgrade my windows to vista. But on the other hand, software such as Red Hat Enterprise Linux5 (RHEL5) gives you such a reason to create a qualitative leap. The following are the four most important reasons why I chose RHEL5. 1) virtualization management is true that every vendor has its own virtualization product. Novell's SLES (suselinuxjavasiseserver

Sometimes you cannot find enough reason to upgrade your system. For example, I cannot find enough reason to upgrade my windows to vista. But on the other hand, software such as Red Hat Enterprise Linux 5 (RHEL 5) gives you such a reason to create a qualitative leap.

The following are the four most important reasons for choosing RHEL5.

1) virtualization Management

It is true that every vendor has its own virtualization product. Novell's SLES (SUSE Linux Enterprise Server) 10 has now supported Xen virtualization technology for several months. KVM (kernel-based virtual machine for Linux) has had exciting new features in the latest Linux kernel product 2.6.20.OpenVZ, and SWSoft and Parallels (an open-source enterprise, and now the two companies have merged.) Some good progress has also been made.

Despite this red hat, it is still one step ahead in virtualization management. Anyone can or try to configure a virtual machine on Linux. However, only when you really know how to deal with problems can you successfully configure your own virtual machine. Any system administrator with such experience can use RHEL 5 to configure many virtual machines, but there are not so many complicated things to consider. Once these virtual machines are set up, they are easier to use and manage.

This is very important.

Al Gillen, vice president of Investigation at the IDC company, talked about this topic. He told me, "to maximize competitiveness and profit comes from management, deploy and track the entire cycle of all layered [Virtual] software." Red Hat has prepared for the battle of Virtualization in the RHEL5 era.

Another element to be ignored is that RHEL 5's integrated virtual software and corresponding management software are packaged together, and users do not have to pay for the added virtual software. As Scott Crenshaw, general manager of RHEL products, recently said, "the benefits of virtualization technology integrated with operating systems are essential and we can provide a more favorable pricing ."

You can not only use a virtual machine to do the work that previously required three to four hardware servers to save money, but also because the virtual machine, virtual Machine management and operating systems are bundled in a product package to save money. If I am a CFO and are looking for a way to reduce IT costs, RHEL5 sounds really good for me.

2) reliable storage

A simple working group or department-level server can store data in the form of a single hard disk or disk array, but a reliable server requires reliable storage technology when working. Use Red Hat Cluster Suite, Red Hat Global File System, and Cluster Logical Volume Manager ), redHat provides you with tools to manage TB-level data storage on local servers, storage area networks (SAN), and staggered clusters.

RHEL5 also provides support for iSCSI disk arrays and remote Direct Memory Access (RDMA) with InfiniBand Technology. For customers who have a lot of storage in a file system, the RHEL 5 Ext3 file system now supports 16 TB file systems, which is really a big number.

If you are using Veritas Software to manage the storage of a company or data center, don't worry: You can continue to use it. Symantec Corp. (Symantec Corp.) announced that in March 14 it will provide core Veritas Storage Foundation, Veritas Cluster Server, and Veritas NetBackup solutions for users using RHEL 5.

Sementech also released a Beta program that combines Storage Foundation and dynamic multi-path technology applications in Xen virtualization. If the plan is completed, the Administrator is allowed to centrally manage the storage virtualization technology and the I/O multi-path of the virtual machine.

Please pay attention again to the word "virtualization". By combining virtual machines and virtual storage, RedHat has created a system composed of technical experts and actuaries. Powerful technical support and easy-to-control costs-who will dislike it?
