VDI environments?
VDI environments?
Correct Answer: A
Question 4
A customer has a group of applications that need storage which can provide low response times. The total I/O requirements are 75,000 IOPs with a 4 kB block size. They will have
500 LUNs and need to keep 30 daily snapshots of each LUN.
What is the smallest XtremIO configuration that will meet their needs?

What is the smallest XtremIO configuration that will meet their needs?
Correct Answer: C
Question 5
You have worked with a customer to successfully evaluate their existing server environment using the MiTrend data analysis tool. You have collected the resulting reports and aggregated the data set. You determine the customer's application workload generates a 50:50 read/write ratio with an average of 500K IOPs during peak business hours.
