A customer has EMC Data Domain system installed in their data center for two weeks. The environment
consists of the following.
1. Data Domain is configured as the primary backup device being shared by Avamar, NetBackup, Oracle
RMAN, and SQL Server backup clients
2. Avamar and NetBackup are using DD Boost to backup a total of 500 clients (250 each)
3. Avamar is configured to allow a maximum of 100 concurrent backups
4. NetBackup is configured to allow 150 concurrent backups writing to the Data Domain with the backup
window starting at 8 P.M. nightly
A total of 50 production Oracle servers are using NFS and 50 production SQL servers are using CIFS, each
performing full backups nightly between 11 P.M. and 5 A.M. The archive and transaction logs backs up every
15 minutes. The retention for all client backups is 30 days.
The backup administrators notice that between 8 P.M. and 11 P.M. every night, the Data Domain CPU is at
100% utilization. What is a potential reason for the high CPU utilization?
