Question 1
A customer wants to have the server two kilometers away from the storage. The DS8886 offers different host adapter types.
What type of host adapters are needed for this configuration?
- Any host adapter requires SAN distance extension equipment at this distance
- Shortwave host adapters
- Longwave host adapters
- Any host adapters when connected to 62 μm fibre cables
Correct answer: A
Explanation:
Incorrect Answers:D: For 850-nm Gigabit Ethernet, 10-Mbit/sec bandwidth values support link lengths of 220 meters over 62.5-micron fiber and 550 meters over 50-micron fiber.References: http://www.redbooks.ibm.com/redbooks/pdfs/sg248047.pdf (System z End-to-End Extended Distance Guide) Incorrect Answers:

Question 3
Which Easy Tier feature should be utilized for a DR site to ensure equivalent performance after a fail over?
- Heat Map Transfer
- Automatic Mode
- Volume Data Monitoring
- Automatic Intra-tier Balancing
Correct answer: A
Explanation:
You can use the Easy Tier Heat Map Transfer Utility to prepare for data recovery. The Easy Tier Heat Map Transfer Utility moves Easy Tier heat map information from primary to auxiliary storage systems. In this way, the performance characteristics of the auxiliary storage are consistently updated to reflect that of primary storage. Auxiliary storage systems are then workload optimized based on primary storage system usage.
