Answer: C,D

Explanation:

According to the IBM Spectrum Protect documentation1, server-side deduplication is a process that eliminates duplicate data blocks on the server during backup operations.

Therefore, two items that should be examined for optimal performance prior to implementing server-side deduplication on a large IBM Spectrum Protect server are:

✑ the storage for the database provides sufficient IOPS. Use a high-performance

disk for the IBM Spectrum Protect database. At a minimum, use 10,000 rpm drives for smaller databases that are 200 GB or less1.

✑ the server has sufficient memory. The amount of memory that is required depends on several factors, such as the number of concurrent sessions, the size of data blocks, and the deduplication ratio1.
