IBM System Storage DS8000 Technical Solutions V3 認定 C4090-453 試験問題：

1. A customer has a UNIX-based 25 TB Oracle/SAP instance currently running on an HP 12000 Enterprise Storage array. The database is very sensitive to response times and is reported to have a peak I/O requirement of over 25,000 I/O per second. The HP device is nearly three years old, and the customer is considering replacing it.
Which of the following is the best way to investigate the IBM DS8000 as a suitable technology replacement for the HP 12000 device?

A) Ask the customer if they can estimate the workload characteristics.
B) Use the Internet to find out the capabilities of an HP 12000 Storage Array and configure an equivalent IBM D58800.
C) Ask the customer on what basis HP sized the HP 12000 Storage Array originally, and make an assessment from that information.
D) Ask the customer for IOSTAT output from the server or servers and use it as an input to a Disk Magic model.

2. Shortly after the installation of a DSS000 and before Call Home has been fully set-up, the customer notices an error message relating to a failed DS8000 primary power supply.
What action should the customer take?

A) Raise a call with the IBM Hardware Support Center
B) Report it to their IBM or Business Partner pre-sales technical support person
C) Mention it to the IBM Customer Engineer at the next monthly review
D) Wait for IBM to make contact

3. The DS Command Line Interface (CLI) of the DS8800 can be used to perform which two of the following configuration actions?
1.Assign RAID ranks to extent pools
2.Install and activate the D68000 storage tier advisor tool
3.Invoke a server failover/fallback
4.Create and assign LUNs to hosts/servers

A) I and 4
B) 2 and 4
C) 1 and 2
D) 3 and 4

4. Which of the following items would suggest that the use of space efficient FlashCopy for the Global Mirror secondary volume could present an issue?

A) The workload has a large amount of heavy sequential write activity
B) There are multiple primary disk subsystems in the Global Mirror session
C) The customer is using Tivoli Storage Productivity Center for Replication to manage Global Mirror
D) There is a long distance between the primary and secondary sites

5. A customer is planning to implement a new DS8000. They want to keep management of the DS8000 to a minimum. Which is the preferred method for allocating volumes to assist with this?

A) Rotate Volumes to allow volumes to fill ranks sequentially
B) Rotate Extents to allow granular placement of extents across multiple ranks
C) Rotate Arrays to allow optimum placement of arrays in the DSS000
D) Rotate Ranks to allow random positioning of ranks across arrays
