- D. for GPES random workloads
Correct Answer: A 🗳️
A customer has purchased a six module XIV Gen3 for a new project, which is located in a new data center. A new requirement states that a portion of the project data must be replicated to an existing six module XIV (Gen2) at the customer's primary data center, 500 km away. The target XIV has sufficient capacity but no Fibre Channel connectivity exists between sites. The customer therefore decides to use iSCSI replication.
Which upgrade is required to meet the requirements?
- A. add modules to the existing (secondary) XIV
- B. add modules to both XIV systems
- C. replace the new (primary) XIV Gen3 InfiniBand switches with Ethernet switches
- D. add modules to the new (primary) XIV Gen3
Correct Answer: A 🗳️
A customer complains that their SAP database now performs worse than it did before being migrated from traditional RAID storage to XIV. The database was configured using 20 x 200GB XIV LUNs presented to an AIX 6 host OS where they are concatenated and striped into six volumes for the databases and logs. No changes have been made in the transition to XIV.
What if anything can be done to improve performance?
- A. the databases should be reorganized into larger volumes on the XIV and not striped within the OS
- B. add Fibre Channel adapters to the host and balance volumes across the adapters
- C. implement static load balancing and increase the queue depth of the host adapters
- D. the SAP volumes should be put into a QoS Performance Class
Correct Answer: A 🗳️
How does the data migration feature enable the smooth transition of a host to an XIV system?
- A. By connecting the host to the XIV, which then provides access to the data on the legacy storage system while transparently copying the data across in the background.
- B. By using the XIV Host Attachment Kit (HAK) migration software to send concurrent writes to the legacy storage system and the IBM XIV simultaneously, while copying the older data across in the background.
- C. By enabling everyXIV PC portto be both target and initiator so that host requests are received bythe XIV and retransmitted to the legacy storage system simultaneously.
- D. By deploying an XIV unique implementation of VMware's Storage vMotion that has been engineered to support Linux and Microsoft hosts natively.
Correct Answer: A 🗳️
