安全性。Centos 6.3符合PCI-DSS(Payment Card Industry Data Security Standards)标准,可删除服务器上不再使用的虚拟机。Centos 6.3的配备了强度更高的AES-CTR (Advanced Encryption Standard Counter Mode)加密算法,以加强OpenSSH(OpenBSD Secure Shell)的安全性。AES-CTR非常适合高速网络环境。Centos 6.3支持同时使用密码和公钥进行身份验证。
存储管理。FUSE(File system in User Space)技术可以绕过缓存直接在设备上读取、写入数据,以确保响应时间一致。管理员现在可以直接通过LVM(Logical Volume Manager)管理RAID,LVM支持RAID 级别4、5、6。这样就不必再使用mdadm实用工具进行RAID配置了。LVM现在已支持自动精简配置(Thin provisioning)。另外,在存储方面Centos 6.3支持以太网光纤通道(FCoE)存储网络。
