A second one with a RAID6 arrays of 7 drives with one offline the array has just been created so it’s under initialization too.
If you find mistakes reply back. The first one with a RAID1 array working fine. PatrickApr 21, With the “Write-back” and “Always Write-back” options the requests are cached in the controller cache and they are immediately acknowledged to the application as completed and only transferred to the hard disk later. In most cases, the enabling of the hard disk cache entails an increase in throughput for write access.

There are three options for setting the write cache: If megasasctl doesn’t work for you, you will have to use the proprietary cli utility from LSI: Management and reporting tools 3. We could combine Areca and 3Ware controllers.
These settings do not ls the read-ahead policy. In the case of the “Adaptive” setting the controller itself attempts to determine whether a read-ahead makes sense or not.
The first one is already setup but we have just plugged a disk bays on the second card. I noticed that strange behavior on an IBM controller.
Please note you need a recent version of smartmontools. Now we’re going to enable write cache. The disk drive identified as! RobSamStuxTheBloke and 1 other person like this.

The packages comes with a python wrapper around megacli and an initscript that periodic run this wrapper to check status. Stux and Kristian like this. We’re going to enable an enhanced version of readahead: Powered by Trac 1. It means it has detected some RAID informations on it, and thus, considers it as a disk being part of an array that may be imported into current controller configuration.

Possibly should have separate sections for 3ware and Areca, as they are LSI based and 3ware owned but they are not inter-operable.

If the system is safeguarded by UPS, the enabling of the hard disk cache is recommended for performance reasons. I made some wrappers around binaries from megactl package to create the node if it doesn’t exist yet.
