3. A software engineering firm has decided to implement shared networked storage to facilitate project development. There are approximately 40 servers in the company; 25% are Solaris and 75% are Windows. The company currently limits growth for storage and does not want to add additional servers for that purpose. It anticipates no more than 30% growth over the next three years.
The storage utilized for the network file systems must be maintained on the most cost effective solution that is the easiest to manage.  However, storage must also be tracked so that required storage for projects can be charged back to the development teams.  Additionally, the network file system will be used for non-project related storage from other departments such as Human Resources and Accounting. Space allocation for non-project files must be monitored and reports generated for management.
In order to choose the most appropriate management application for this environment, you will need to analyze specific qualification information. What is the best methodology for collecting this information?
A. Provide the EMC qualification document to the customer and have them complete the form
B. Collect GRABs from all server systems and process with HEAT. Consolidate your findings and summarize on the qualification document
C. Interview product development team leads and department heads. Determine current and projected storage requirements and any retention policies currently in use
D. Request network configuration information and performance characteristics. Evaluate ability of the network to support additional management monitoring
Answer: C

     Oracle statistics for the applications
     EMC Grabs on the newer servers
Your hypothesis is that caching characteristics on the CLARiiON array are not appropriate. What is the best method to validate this hypothesis?
A. Compare current CLARiiON configuration with installation settings made by Professional Services
B. Review overall mixture of applications to determine if cache settings are appropriate
C. Ask the Customer Engineer to disable Read caching and see if that helps
D. Run HEAT reports on the GRABs
