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?

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?

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?

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.
Which type of workload change could explain this situation?

A company plans to install a Symmetrix VMAX in a Fibre Channel SAN environment. They need to protect data access to the Symmetrix port level.
Which feature needs to be implemented?

You are provisioning EMC Symmetrix VMAX storage for a large ESXi environment. A request has been made to present 320 LUNs to each of the physical hosts. When you examine the storage configuration on each of the hosts, you are able to see only some of the drives assigned.
What could be causing this issue?

A company currently has a PowerPath-enabled SAN environment with many hosts. A majority of the hosts have storage allocated from Fibre Channel drives and have poor service time. They intend to design a solution for Symmetrix VMAX storage consolidation to replace their current storage infrastructure.
What is a key design guideline to overcome this issue?

Four DRV devices are configured in an EMC Symmetrix DMX array. As per current settings, a maximum of four simultaneous swaps and eight swaps per day are allowed in the Symmetrix.
Optimizer analyzes the back-end I/O and decides to swap.
How many swaps are allowed at the same time?

You are performing a migration from DAS-based Microsoft SQL Servers to an EMC Symmetrix VMAX. In order to assure the highest levels of performance and availability, you ensure that all EMC best practices are followed.
In order to protect the database volumes from having write pendings being overwritten by new writes to the same area in global memory, which array setting should be configured?

You have been tasked with gathering performance data for a clustered Microsoft SQL Server database that resides on a Symmetrix VMAX LUN. Which Perfmon counter must be used to collect the write IOPS metric?
