磁盘冗余阵列raid

Disk and Data Availability is important for systems administrators. There are different ways to implement. RAID or Redundant Array Of Independent Disks is one of the most popular one. RAID 6 is complex disk architecture which is used to protect against two disk failure. We have all ready examined RAID types in this following tutorial.

磁盘和数据可用性对系统管理员来说很重要。 有不同的实现方法。 RAID或独立磁盘冗余阵列是最受欢迎的磁盘之一。 RAID 6是复杂的磁盘体系结构，用于防止两个磁盘故障。 在下面的教程中，我们已经准备好检查所有RAID类型。

How Raid Disk Configuration Works and Information About Raid 0 , Raid 1 , Raid 5 , Raid 10

Raid磁盘配置如何工作以及Raid 0，Raid 1，Raid 5，Raid 10的信息

优点(Advantage)

Configuration of the RAID 6 is high fault tolerant. There is two disk spare which means we can continue to operate even two disks fails. This is useful for environments which needs long data retention periods.

RAID 6的配置具有很高的容错能力。 有两个磁盘备用磁盘，这意味着即使两个磁盘出现故障，我们也可以继续操作。 这对于需要较长数据保留期的环境很有用。

坏处 (Disadvantage)

There may be some little disadvantages using RAID 6. Using two disk will require some parity management and compute. This parity management and compute will create some overload over disks and some latency.

使用RAID 6可能会有一些小缺点。使用两个磁盘需要进行奇偶校验管理和计算。 这种奇偶校验管理和计算会在磁盘上造成一些过载和延迟。

There is also some ownership cost problem which means this RAID 6 will cost more than RAID 6 and other RAID solutions. We will need more disks to implement RAID 6.

还有一些所有权成本问题，这意味着该RAID 6的成本将高于RAID 6和其他RAID解决方案。 我们将需要更多磁盘来实现RAID 6。
