How does an BM XIV System provide a guarantee of consistent performance even under the most dynamically changing elastic cloud workload environments?
A . Use of a distributed grid architecture
B . Support for multiple versions of OpenStack software
C . Built in performance monitoring of key resources
D . Capacity on Demand addition of useable storage

Answer: A

Explanation:

IBM XIV Cloud Storage for Service Providers, or client hosted cloud solutions require elastic, rapid response, and dynamic demand that is captured within XIV’s 485

TB linear scalability, and the immediate and automatic redistribution, without interruption, of added capacity. The grid design stripes data across all modules and

disks, incorporating data redundancy for consistent and predictable I/O performance that is always load balanced.

Incorrect Answers:

D: With Capacity on Demand (CoD) you effectively buy a certain amount of capacity up front but also get up to 3 more modules shipped with the machine. You can

start using this extra capacity when your business requirements demand it, at which point you will be asked by IBM to purchase it. The advantage here is that you

physically get a bigger machine up front with all the performance benefits that bestows, plus you don’t have to contact IBM to start using that extra capacity.
