QUESTION 59
A customer currently has 10 IBM AIX servers. A production IBM AIX database server has 1 TB of direct-attached storage that is dedicated to database files and log files, of which 800 GB is used. The database files and log files are synchronized from the production database server to the data-mining servers for the purposes of data extraction only. The data-mining servers each have 1 TB of direct-attached storage that is dedicated to the replicated database files and log files. The customer is considering purchasing the Cisco MDS 9216 Fabric Switch and utilizing the read-only zoning feature to enable the data-mining servers to read from the production-server volume on the disk array. How much storage capacity could be reclaimed by using this approach?
