Question #8 (Topic: )
You have been asked to design an XtremIO storage array solution that will be used for two
large applications workloads. One overload will generate approximately 150,000 write IOPs
with an average 4 kB I/O size. The second write workload will have an average I/O size of
128 kB and will generate approximately 2 GB/s of throughput.
At a minimum, how many X-Bricks are needed in a single cluster to meet this requirement?

Question #9 (Topic: )
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 customers application workload generates
a 50:50 read/write ratio with an average of 500K IOPs during peak business hours.
Which recommended XtremIO model meets the customers needs?

Question #10 (Topic: )
A customer is considering migrating their existing non-EMC storage arrays to an XtremIO
array. The current environment consists of 350 servers running VMware ESXi 5.5 with
5000 virtual machines. The customer has various tools in place to monitor performance
and collect statistics. On average, their service time is 32 ms and utilization is at 75%. In
the past, the customer has had performance issues.
Based on Littles Law, what is the calculated response time on the existing environment?
