Minimum Power:将static设置设为最低级。 Balanced:static设置随配置而定。 Maximum Performance:将static设置设为最高级。 默认为“Maximum Performance”。 Survival Mode 当RAID控制卡的温度超过阈值时,Survival Mode将允许控制卡将所有的功耗配置设置为最小值,选择该模式后,服务器将继续在这种环境下工作,但性能可能...
Table 2-8 lists the performance of different RAID levels, the minimum number of drives required, and the drive utilization. Table 2-8 RAID levels RAID Level Reliability Read Performance Write Performance Drive Usage RAID 0 Low High High 100% RAID 1 High High Medium 50%...
There must be at least two hard disk drives. IDE, small computer system interface (SCSI), or mixed architecture is permissible. All disks involved in the striped volume must be dynamic disks. Each portion of the free space must be exactly the same (for example, the size and file system ...
Disks: A minimum of two disks are needed to support striping. Type: Any disks involved in striping must be dynamic. Conversion from basic to dynamic goes very quickly without data loss. After you complete the conversion procedure, you must restart the computer. ...
Minimum number of drives is six. Level 60: RAID level 60 employs the features of levels 6 and 0. A RAID 60 array combines the straight block-level striping of RAID 0 with the distributed double parity of RAID 6. That is, a RAID 0 array striped across RAID 6 elements. A RAID 60 ...
RAID-0:当潜在的数据丢失并不严重时,可与工作站类型的应用程序一起使用。提供最高的性能和最高的性价比。 RAID-6:不太可能与固态盘一起使用。 主要设计用于重建时间较长的高容量硬盘。 建议对英特尔®固态盘使用哪种 RAID 设置? 最佳RAID 设置与硬盘驱动器几乎相同: ...
RAID 10, also known as RAID 1+0, is a hybrid RAID configuration that combines the mirroring of RAID 1 with the striping of RAID 0. It requires a minimum of four drives to implement and is designed to offer the performance benefits of RAID 0 with the redundancy of RAID 1. In asoftware...
今天干了一件蠢事,距离删库跑路,只差一步。把一块RAID0的磁盘给拔掉了,拔掉之后发现这是一块数据盘,幸好这个数据库是一台备库。赶紧动手恢复,以下是恢复的过程。 首先把拔下来的盘插回去,通过Megacli查看状态是这样的 root# /opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall ...
