有关RAID译文指正 [Copy link] 中文

What RAID levels are supported? What is the granularity of RAID levels to operate concurrently and over what number and types of disk drives? Also, look into what flexibility you have for tuning RAID, as well as system and automatic RAID tuning by the storage system or controller for hands off operation. The importance of having support for multiple concurrent RAID levels is to be able to place log files for email, database and other applications on RAID 1 or RAID 10 for read/write intensive workloads while leveraging RAID 5 for less update intensive workloads as an example.
试译:
支持哪些RAID级别?多种RAID级别可同时使用的细粒度如何?可以在多少数量及哪些类型的磁盘驱动器上使用?还要关注你在调整RAID方面有多大的灵活性,以及存储系统或者控制器针对切换操作的系统和自动RAID调整(???)。同时支持多种RAID级别的重要性在于,举例说,能够把电子邮件、数据库及其他应用的日志文件放在RAID 1上,或者使用RAID 10来处理读/写密集型的工作负荷,或者利用RAID 5来处理不太频繁更新的工作负荷。

我的理解

试译
以及由存储系统或者控制器对系统和RAID进行自动调优.


1) hands off : not involving participation or intervention 自动地, 不用人为重新设置.

2) 感觉这个FOR是表目的.

3)TUNE:  
To adjust (an engine, for example) for maximum usability or performance; To optimise a program or system for a particular environment. 不仅仅是调整, 它含有"性能调优/优化" 的意思

4) on RAID 1 or RAID 10 for read/write intensive workloads
将日志文件放在在RAID 1或者RAID 10 上来处理读/写密集型的工作负荷

RAID 1 也是用来处理读/写密集型的工作负荷(在写方面, 相当于single disk). 如果一个应用update很频繁的话, 就会快速产生LOG FILE数据, 为了确保高可用性+R/W 性能, 所以将LOG FILE做到RAID1 或 RAID 1+0 上. 后面RAID5放一些变化不大的文件(如影片,系统文件,程序文件等), 保证读的性能+高可用性就可以了,

我怀疑 system and automatic RAID tuning 是 system [RAID tuning] and automatic RAID tuning 。

多谢指正!看明白了。

fyi

look into 不是关注的意思,应该是"调查,找出,了解"的含义

Also, look into what flexibility you have for tuning RAID, as well as system and automatic RAID tuning by the storage system or controller for hands off operation
中心含义是:看看到底你在人工对RAID进行调优上,到底具有多少灵活性;或,想获得非人工操作,而让存储系统或控制器进行系统和自动RAID的调优上,到底有多少灵活性

by 这里是指:通过。。方式
