Q7. - (Topic 2)
You are designing the Symmetrix VMAX architecture for a DAS-to-SAN SQL Server migration. Currently all user databases reside on a single locally-attached disk enclosure, mounted to "M:\". You have decided on RAID-1 protected 15,000 RPM drives for the new SQL environment.
Last week, you configured Perfmon to record the current IOPS load of the databases during the 8-hour business day, Monday through Friday as shown in the exhibit. During an average business day, the transaction log processes 43 GB worth of data.
Following EMC best practices, which discount can be taken from the overall write IOPS when calculating for the database writes?
A. 196
B. 392
C. 597
D. 989
Answer: A
Q8. - (Topic 2)
An SRDF configuration is running in SRDF/A mode. The customer's decision to switch from SRDF/A to SRDF/S is rejected. At which percentage of write cache in use at the SRDF R2 site will this occur?
A. 50%
B. 100%
C. 80%
D. 90%
Answer: A
Q9. - (Topic 1)
What is a best practice when configuring a Symmetrix VMAX for optimal performance and cost?
A. Different drive types are mixed and spread throughout the array.
B. Dedicated engines have appropriate drive types to meet application needs.
C. A dedicated array with Enterprise Flash Drives (EFD).
D. A dedicated array based upon application requirement.
Answer: A
88. - (Topic 1)
Which information is needed when designing an Open Replicator solution?
