Demo Questions
Question 1
A technical specialist is conducting a disk technology briefing to position the IBM FlashSystem V9000 against flash drives in an IBM Storwize V7000. The customer asks, “Why is SSD latency greater than a flash module?”
How should the technical specialist respond to the customer?
- Larger capacity SSDs use TLC technology which is slower than MLC
- The SSD is using a traditional drive style interface protocol, which can cause a performance overhead.
- SSDs use much slower internal SLC flash technology than the IBM FlashSystem, which uses eMLC/MLC.
- The cache memory in the IBM Storwize V7000 is less, which increases latency.
Correct answer: A
Question 2
A customer has two IBM Storwize V7000 I/O groups. As part of its business continuity plan, one unit is located within its primary site and the other at a disaster recovery site. The customer synchronously replicates between each IBM Storwize V7000.
What should the customer configure to provide fast non-disruptive failover in case of an outage?
- Transparent Cloud Tiering
- Stretched cluster
- HyperSwap
- Global Mirror
Correct answer: C
