Question : Storage efficiency

Hello

I obtained the following info from Redhat about RAID & Storage efficiency.

RAID0  - No place for RAID0 in production environment.

Storage efficiency: 100%

RAID 1

Storage efficiency: (100/N%) where N=#mirrors

RAID 5

Storage efficiency: 100*(1-1/N) % where N=#devices

RAID 6

Storage efficiency: 100*(1-2/N) % where N=#devices


RAID 10

Storage efficiency: (100/N) %  where N=#devices/mirrors

I know this might sound stupid, but I just want to know what dose that mean, can someone provide examples for every RAID equation?

I have server with 10 Hard drives, I would like to implement software RAID using Redhat 5

Thank you

Answer : Storage efficiency

The problems with SendKeys is that the intended target application Window must be the Active window at the time the SendKeys command is executed.  If it isn't, then SendKeys will fail.  Thus the issue with SendKeys is that the programmer must control the timing of the execution of  the SendKeys function.  there are at least two ways to structure your code to avoid problems.........see the various code examples in this link:
