Oracle Linux 7.0 OS Has XFS as Default File System and Unbreakable Enterprise Kernel Release 3
================================================================================
![The new Oracle Linux 7.0 is out](http://i1-news.softpedia-static.com/images/news2/Oracle-Linux-7-0-OS-Has-XFS-as-Default-File-System-and-Unbreakable-Enterprise-Kernel-Release-3-451894-2.jpg)
**The Oracle Linux 7.0 operating system has been released by Oracle and brings numerous new features and changes, like Unbreakable Enterprise Kernel Release 3 and a new default file system.**
The Oracle developers have gone through a couple of Release Candidates for this new build of the distribution and now the final version has arrived. As expected, it's packed with a ton of modifications, which include the new XFS as the default operating system, Btrfs as an alternative, Linux Containers (LXC), DTrace, Ksplice, Xen enhancements, and the Unbreakable Enterprise Kernel Release 3.
As opposed to the more popular EXT4 file system, XFS has one major advantage. It allows users to have 500 TB for the file system size, which is ten times more than what you would get with EXT4. The only drawback is that it only allows for 16 TB maximum file size.
The distribution features two supported kernels. One is the Red Hat Compatible Kernel (RHCK), based on mainline Linux version 3.10, and the second one is their own version, which is called the Unbreakable Enterprise Kernel Release 3 (UEK R3), and starting with 3.8.13 it's based on the mainline Linux version 3.8. You might remember that Linux Kernel 3.8.x has already reached end of life, but it looks like Oracle is maintaining its own branch.
“Available for download from Oracle Software Delivery Cloud, Oracle Linux 7 is free to download and distribute. All bug fixes and security errata are published to Oracle's public yum servers, allowing customers to install the same code across all their deployments, with or without a subscription, and creating a simple migration path from free to paid. No reinstalls are required.”
“This release builds on Oracle's approach to providing support for emerging technologies, such as OpenStack, while delivering the latest Linux innovations, tools, and features customers and partners need to deliver enterprise-grade solutions for the modern data center,” reads the official announcement.
According to the changelog, Ksplice has been implemented for zero-downtime kernel security updates and bug fixes, systemd has been implemented as the new system manager, Grub2 is now the default boot loader with support for additional firmware types (like UEFI), and an improved Anaconda installer, a few new Apache Web Server features, GPT support, and numerous security features and improvements have been added.
More details about the latest Oracle Linux distro can be found in the official [announcement][1].

Oracle Linux 7.0系统使用XFS作为默认文件系统，和第三代“坚不可摧的企业级内核”
===
![The new Oracle Linux 7.0 is out](http://i1-news.softpedia-static.com/images/news2/Oracle-Linux-7-0-OS-Has-XFS-as-Default-File-System-and-Unbreakable-Enterprise-Kernel-Release-3-451894-2.jpg)
**Oracle已经发布了Oracle Linux 7.0操作系统，新系统带来了大量的新特性，比如“第三代坚不可摧的内核”（Unbreakable Enterprise Kernel Release 3）和一个新的默认文件系统**
为了这次新的发行版的发布，Oracle的开发者们已经放出过两个预览版，现在最终版终于来了。果然，它有着成千上万的修改，其中包括使用新的XFS作为默认的文件系统**[注：原文为操作系统，应该是笔误]**，Btrfs作为可选文件系统，Linux Containers (LXC)， DTrace，Ksplice，加强版Xen和“第三代坚不可摧的企业级内核”。
作为广泛流行的文件系统EXT4的对抗者，XFS有一个显著优势。它所允许用户的文件系统的大小达到了500TB，这比你在EXT4文件系统中所能达到最大值的十倍还多。唯一的缺点是单个文件的大小最大仅为16TB。
这个发行版的一大特色是它支持两种内核。一个是红帽兼容性内核(RHCK)，基于Linux内核版本3.10，第二个是Oracle自己的内核版本“第三代坚不可摧的内核”（UEK R3），版本号从3.8.13开始，因为它基于3.8的Linux内核。你或许还记得Linux内核3.8.x已经寿终正寝，但是看来Oracle一直在维护着自己的分支。
“已经能够从Oracle软件发布云上下载了，Oracle Linux 7可以免费下载和部署。所有的bug修复和安全勘误会被发布到Oracle的公共yum服务器上，不管有没有付费，用户都能安装同样的代码，并且从免费到付费的迁移十分简单，无需重新安装。”
“当发布最新的Linux更新，工具以及推送给客户和参与者新功能的时候，需要为现代化的数据中心提供企业级的解决方案。为此最新的发行版是构建在Oracle对于像OpenStack这样的新兴技术提供支持的基础上，”从官方声明可以看出。
通过变更记录来看，Ksplice已经为了实现零宕机的内核完成了安全更新和bug修复，systemd也成了新的系统管理工具，Grub2现在是默认的启动引导程序，并且支持新的固件类型（比如UEFI），还有一个加强版Anaconda安装器，一个新的Apache Web服务器，支持GPT，和大量的安全特性被添加进来。
更多关于最新的Oracle Linux发行版的详细内容可以参考官方[声明][1]。
