What configuration would you recommend to the customer?
You are being asked to help a customer that is having issues with their new OLTP
application that they have just connected to their existing VNX. The OLTP Administrator has
created a 2 TB pool LUN on 8 NL-SAS drives in a 6+2 raid 6 configuration. The customer
does not have the budget to purchase more hardware this quarter but does have a mixture
of SAS and NL-SAS drives you can use. What configuration would you recommend to the
customer?

How many 200 GB FAST VP optimized Flash drives would be needed to handle the load of the working data set?
Click the calculator icon in the upper left-hand corner.
Your customer has LUNs with a total size of 25,000 GB. The total I/O load is 10,000 IOPS,
with a 4:1 R/W ratio. Analysis of your customer’s data indicates that data skew is 95%. RAID
5 (4+1) is used exclusively in the environment.
