During monthly loads of a data warehouse, the customer observes significant increased response time on their OLTP database. Both applications reside on the same tier-1 storage and are replicated using the same SRDF/S links. During these high utilization periods, which tool can be used to give preference to servicing the OLTP database I/O?

QUESTION NO: 8
Click on the calculator icon in the upper left corner. A customer would like to add a new database application to their VMAX. This application is expected to produce 3000 I/O per second with 45% read hit and 25% write. The customer expects to use RAID 5 (3+1) on new drives that are not yet utilized. These drives perform 100 SCSI commands per second (read/writes) at 100% utilization.
Assuming drive utilization should not exceed 70%, how many physical drives, excluding hot spares, does the customer need to achieve performance requirements?

QUESTION NO: 9
Click on the calculator icon in the upper left corner. Refer to the exhibit.
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 "N:\". You have decided on RAID-5 protected 15,000 RPM drives for the new SQL database and RAID-1 for the transaction log.
Last week, you configured Perfmon to record the current IOPS load of the databases during the 8-hour business day, Monday thru Friday as shown in the exhibit. During an average business day, the transaction log processes 87 GB worth of data.
Following EMC best practices, what is the minimum number of spindles required to satisfy the performance needs of the database?
