What might be causing this low utilization?
You are examining the performance of a weekly backup. You notice that the utilization for the Symmetrix front-end director CPUs involved in the backup is very low.
What might be causing this low utilization?
How can this impact to the nightly process be prevented?
Storage administrators for a Symmetrix running Enginuity 5773 need to increase allocated storage for Microsoft Exchange LUNs without interrupting the mail server’s operation. Performing a protected striped LUN expansion causes a critical nightly clone operation to run for hours instead of minutes. This impacts later dependent jobs, preventing production operations from completing.

If Oracle is not placed in hot backup mode, what is the state of the Oracle tablespaces in the replica?
A database administrator is concerned about the performance impact of placing a busy Oracle instance in hot backup mode. They want to take TimeFinder/Clone consistent replicas every three hours.
If Oracle is not placed in hot backup mode, what is the state of the Oracle tablespaces in the replica?
What could be causing the failure?
A company is using Replication Manager to backup their Microsoft Exchange 2010 environment using Microsoft Volume Shadow Service (VSS). Each Exchange database and log volume has separate Symmetrix VMAX LUNs. A Replication Manager backup job for a Microsoft Exchange 2010 server with 20 databases keeps failing to complete a backup.
What could be causing the failure?
What are the access control rights that need to be given to the Symmetrix Service Processor?
Access control is being deployed in an EMC Symmetrix environment. What are the access control rights that need to be given to the Symmetrix Service Processor?
What is the likely cause for the low disk space?
A company is using Replication Manager to back up multiple Microsoft Exchange 2010 mailbox servers. They have configured a backup job defining the options for performing VSS backups of each Exchange storage group on each server. All backups are executing successfully, but the company has recently started to experience problems with low disk space on the transaction log volume of one particular storage group.
What is the likely cause for the low disk space?
What must be done before unmounting the file system and performing the TimeFinder restore?
A company notices that one of their Oracle data files is corrupted. The storage administrator must perform a TimeFinder restore of the corrupted tablespace.
What must be done before unmounting the file system and performing the TimeFinder restore?
Which step should be taken to meet this requirement?
You are using Replication Manager to create application consistent TimeFinder clones of your Microsoft SQL environment. Each night six databases are replicated, and then the replicas are subsequently backed up to tape. You have been tasked with minimizing the replication window while reducing the overall impact the replication process has on the array.
Which step should be taken to meet this requirement?
To meet the RTO, which change to the environment is recommended?
A production Oracle database with a high transaction rate recently experienced slow performance.
The storage for the database is on an EMC Symmetrix VMAX and is laid out according to best practice principles. Further investigation found that there was a physical drive failure affecting one of the storage volumes where the database was stored. The database volumes were on RAID 5 metavolumes.
The database administrator is concerned that the RTO will not be met in the future if a database recovery was required at the same time as a drive failure. To meet the RTO, which change to the environment is recommended?
Which type of workload change could explain this situation?
A storage administrator is baselining performance for a new server attached to an EMC Symmetrix VMAX array. The server has two Fibre Channel HBAs each connected through separate fabrics to two FA ports on the Symmetrix.
The administrator is looking at the Director and Port statistics in Performance Manager. Every day there are several hours where the “Port % Util” statistics increase noticeably but the “I/O per sec” and “Dir % Util” does not change significantly.
