IBM XIV Storage System Technical Solutions V4 Sample Questions:

Question 1

A customer wants to set up a Windows 2008 cluster with three nodes, with application data presented from a fifteen module XIV Gen3. All three nodes will run applications under normal operating conditions. Each node has a single dual- port Fibre Channel host bus adapter.
Assuming a dual fabric SAN, how should the cluster nodes be zoned to the XIV within each SAN?

A. each host port should be zoned to a single port from two XIV modules, ensuring that the host ports from the remaining two nodes are zoned to different XIV modules
B. each host port should be zoned to a single port from three XIV modules, ensuring that the host port on the second fabric is zoned with a single port from the remaining three XIV modules
C. ports for all three nodes should be grouped together into a single zone, along with a single XIV port from each available XIV interlace module
D. each host port should be zoned to a single port from one XIV module, ensuring that no other host ports are zoned to the same module

Question 2

A customer has requested a highly available solution with fully concurrent fail over for a VMware farm of hosts. The customer also has Oracle databases that demand very low latency (0.5 ms and lower). What would be the best solution for this environment?

A. Two XIV systems setup in synchronous mirrorwith SSD5 and VMware SRM
B. SVC stretch clusterwith XIV and IBM FlashSystems (RamSan), plus enable EasyTier
C. Two XIV systems setup in asynchronous mirror with SSDs and VMware SRM
D. SVC with XIV and IBM FlashSystems (RamSan), plus enable Easy Tier

Question 4

A customer builds a solution with SAN Volume Controller and an XIV system.
For best performance how many paths should be used between the SVC and the XIV system?

A. each I/O group must have one path to all available XIV interface modules
B. each SVC port should have one path to all available XIV interface modules
C. all XIV interface module FC ports should be zoned to each FC port on each SVC node
D. each SVC cluster should have one path to all available XIV interface modules

Question 5
