RAID 0 is not recommended for data disks since it has no fault tolerance features.
不推荐对数据磁盘使用RAID 0,因为它没有容错功能。
It has 8 GB of RAM and three DS4000 disk subsystems configured as 14 RAID 0 arrays.
它有8GB的RAM,有三个DS4000磁盘子系统,配置为14个RAID 0阵列。
RAID 0 works by breaking data into fragments and writing to all disk simultaneously.
RAID0工作原理是通过把数据分解成片段,并行写入所有磁盘。
On a side note, in mathematical terms, RAID 1 is an AND function, whereas RAID 0 is an OR.
从一个方面说明,在数学术语上,RAID1是“和”函数,而RAID0是“或”函数。
Linear is similar to RAID 0, except that data is written sequentially rather than in parallel.
线性类似于RAID0,除非数据是串行写入而不是并行。
The mail databases were spread across three IBM FAStT 600 arrays of 800 GB each, also RAID 0.
邮件数据库分散在三个IBMFAStT 600阵列上(每个 800GB,也是RAID 0)。
The mail databases were spread across five IBM FastT 200 GB arrays, also configured in RAID 0.
邮件数据库分布于五个IBMFastT 200GB阵列,同样配置为RAID 0。
Two or more devices are configured in a RAID 0 setup, while the third (or last) device is a parity device.
2块或更多的设备配置成RAID0,第三块或最后一块设备是校验设备。
For speed (but no data protection other than error detection), you can employ striping across devices (RAID 0).
为提高速度(不存在错误检测以外的数据保护),您可以跨设备进行条带化(RAID 0)。
The mail databases were spread across five IBM FAStT 600 arrays, also RAID 0. Network access was through a single 1 GB Ethernet adapter running in full duplex mode.
邮件数据库分散在5个IBMFAStT 600阵列上,其配置也是RAID 0。网络访问是通过一个1GB的以太网适配器进行的,它采用的是全双工模式。
AIX has many levels of RAID technology incorporated into it for no additional cost; these technologies can be employed at a software level, such as striping (RAID 0) and mirroring (RAID 1).
AIX已经融合了很多级别的RAID技术,且无任何其他的成本;这些技术可在软件级别上使用,比如条带化(RAID 0)和镜像(RAID1)。
From a reliability standpoint, RAID-0 has the same characteristics as linear mode — the more drives you add to the array, the higher the probability of volume failure.
从可靠性的立场来看,RAID - 0模式与线性模式具有同样的特征——向阵列中添加的驱动器越多,卷的故障概率就越高。
To set up a RAID-0 volume you'll need two or more equally (or almost equally) sized partitions.
要安装RAID - 0卷,您需要有两个或多个大小相同(或是几乎相同)的分区。
The RAID-0 code will evenly distribute writes (and thus reads) between all constituent partitions.
RAID - 0代码将在所有的组成分区之间均分读写。
RAID-0 is ideal for applications for which you need maximum IO performance, since it's the highest-performing RAID mode available.
RAID - 0对于需要获得最大io性能的应用程序来说很理想,因为它是目前性能最好的RAID模式。
To figure out the probability of failure of your RAID-0 volume, simply add together the probabilities of failure of all constituent drives.
要计算您的RAID - 0卷的故障概率,只需将所有组成驱动器的故障概率相加即可。
Neither one is technically a form of RAID at all, since RAID stands for "redundant array of inexpensive disks", and RAID-0 and linear mode don't provide any kind of data redundancy.
从技术上讲,二者都不是RAID,因为 RAID代表“廉价磁盘冗余阵列”,而RAID-0和线性模式都不提供任何类型的数据冗余。
If you're creating a RAID-0 volume out of SCSI devices, be aware that the combined throughput of all the drives can potentially exceed the maximum throughput of the SCSI (and potentially PCI) bus.
如果您准备用SCSI设备创建一个RAID - 0卷,注意不要让所有驱动器的总吞吐量超过SCSI(和PCI)总线的最大吞吐量。
If you're using RAID-0, make sure they're on separate disks and approximately the same size.
如果您使用的是RAID - 0,则应确保这些磁盘分区位于不同的磁盘上,并且其大小近似相同。
However, both modes — especially RAID-0 — are very useful.
然而,两种模式——尤其是RAID - 0模式——都非常有用。
To create a RAID-0 volume, you'll need two or more equally sized partitions located on separate disks.
要创建RAID - 0卷,您需要彼此位于不同磁盘上的两个或多个分区。
Nevertheless, RAID-0 is immensely useful.
尽管如此,RAID - 0还是极其有用的。
If you're creating a RAID-0 volume using IDE disks, you should try to use UltraDMA compliant disks and controllers for maximum reliability.
如果您正在用IDE磁盘创建RAID - 0卷,您应该尽量使用符合UltraDMA的磁盘及控制器,以获得最大的可靠性。
