E20-526 Question #73: Real Exam Question with Answer & Explanation
The correct answer is C. 3. Required bandwidth= 100,000 8 1024 bytes Provided bandwidth between XtremIO arrays with compression over Fiber Channel: 300 1024 Required number of RPAs: 100,000 8 1024 / (300 1024 1024) = 800,000 / (300 * 1024) = Three RPAs would be enough.
Question
Refer to the Exhibit. A customer has the following XtremIO environment: Read/write ratio is 3:1 I/O size is 8K Write pattern is random Data is compressible If an application generates 100,000 IOPS of traffic, how many RPAs are needed to replicate the traffic from one XtremIO array to another XtremIO array over IP?

Explanation
Required bandwidth= 100,000 * 8 * 1024 bytes Provided bandwidth between XtremIO arrays with compression over Fiber Channel: 300 * 1024 * Required number of RPAs: 100,000 * 8 * 1024 / (300 * 1024 * 1024) = 800,000 / (300 * 1024) = Three RPAs would be enough.
