Question 4

A customer already has a D38000 with RAID 10 protection for their production data. They want to implement NL-SAS drives in the same DS8000 for archive data.
Which disk protection should be used for this and why?

A. RAID 0 because archive data isn't mission critical and they should use tape backup

B. RAID 6 because the time to rebuild NL-SAS drives would leave the array exposed for a long time after a single disk failure

C. RAID 5 because data on these drives is less critical than the production data

D. RAID 10 because this is the only protection supported for NL-SAS drives

Correct Answer: B

Question 7

The customer's data center has an elevator with a maximum load capacity' of 2200 lb (1000 kg). A Disk Magic study has proved that the performance requirements of the workload are at Enterprise class levels.
What should be recommended?

A. Redesign the solution to use modular systems, like IBM Storwize V7000, which could be delivered in lighter shipments.

B. Order a DS8800 with minimal disks and then MES upgrade with additional capacity' to the customer's requirements.

C. Configure the feature code on DS8800 which allows a shipping weight reduction.
