What a question!!!

[kay-boy]

An application specifies a requirement of 200GB to host a database and other files. It also specifies that the storage environment should support 5,000 IOPS during its peak processing cycle. The disks available for configuration provide 66GB of usable capacity, and the manufacturer specifies that they can support a maximum of 140 IOPS. The application is response time sensitive and disk utilization beyond 60 percent will not meet the response time requirements of the application. Compute and explain the theoretical basis for the minimum number of disks that should be configured to meet the requirements of the application.

Would short stroking help? (HA HA)

How did your instructor tell you to solve this? Why are you going online for your homework help?

 

[kay-boy]

lol just shut up if you can't solve it....

And so polite to. Never mind then.

A student goes to an Internet forum to get his homework done. Every time he posts a question, he gets two snarky responses. How long will it be before the student gets a clue?

Maybe take your own advice here? Just tossing that out there on the table......lol.

:lol:
Well, now I know what kind of questions to look out for if I ever get a networking degree.

Who uses 66 GB spinning drives anymore? I assume they are spinning drives because SSD supports way more than 140 IOPS.

Actually guys I've been thinking about this. Would short stroking help? I know the Avg transfer rates would go up, but would the IOPS go up as well or is that solely a function of the controller? If you SS these hypothetical 66GB down to 10 or 30GBs, could you raise the 140IOPS up to 160? 180?

I would imagine that its all for not. You'd need a controller to handle a large number of drives to get to 5k, and I'm assuming we aren't talking onboard.
