What determines the potential data loss in an SRDF/A solution?
A customer who is currently using SRDF/AR is migrating to an SRDF/A solution. They need to configure the environment to meet their RPO requirements.

Which technology makes this possible?
A new Rainfinity customer has just implemented a VLAN configuration. The customer is concerned about how the servers in a private VLAN can see clients in a public VLAN.
Which technology makes this possible?
What should you recommend to manage the clone operations efficiently and to improve the backup performance?
A customer is using EMC NetWorker for backups in their environment. They have multiple physical tape libraries that are used for backups and clone operations at the primary data center and a disaster recovery site. The backup data is cloned daily to the remote disaster recovery site.
Their backups are taking longer and are not able to complete the clone operations within one day to meet their service level objectives. What should you recommend to manage the clone operations efficiently and to improve the backup performance?
What is the impact on virtual volume availability when one node of the Control Path Cluster (CPC) fails?
A customer has dualmirrored Cisco fabrics with Invista virtualization. What is the impact on virtual volume availability when one node of the Control Path Cluster (CPC) fails?
Which tools should be used to determine the appropriate RAID 5 disk configuration?
A customer has a mix of Windows, Solaris, and HPUX servers connected to a CX380. They want to move the data for the Solaris hosts that is currently on RAID 1/0 groups to RAID 5 groups.
Which tools should be used to determine the appropriate RAID 5 disk configuration?
What is the least disruptive SAN solution that you should consider?
A customer’s storage environment is organized into four singledirector fabrics. The directors are MDS9509s with 64 switch ports in each. No more than 70% of available ports are in use.
The customer needs hosts in each fabric to access storage in the other three fabrics. It is acceptable for hosttostorage traffic to traverse up to one hop.
What is the least disruptive SAN solution that you should consider?
What is the reason for this lower than expected deduplication performance?
A customer is looking for a deduplication backup solution for their environment and is evaluating EMC Avamar. The customer backs up five test clients of various platforms in their environment to the Avamar server for one week. They are disappointed by the percentage of deduplication that is occurring.
What is the reason for this lower than expected deduplication performance?
What is the best migration method to achieve the desired objectives and design considerations?
A customer is planning to migrate their data and Windows hosts from an existing CLARiiON array to the DMX in their enterprise SAN. The customer would like to perform the migration with the least amount of downtime and no host involvement.
What is the best migration method to achieve the desired objectives and design considerations?
Based on the information provided, what is the minimum number of ISLs required between each switch pair?
Refer to the Exhibit.
A customer is creating a full mesh fabric out of four switches, each with 32 4 Gb/s ports. The observed loads are displayed in the exhibit.
Based on the information provided, what is the minimum number of ISLs required between each switch pair?
Which tool should you use to gather this information?
You need to perform an assessment of your customer’s backup infrastructure that is using EMC NetWorker. You will be collecting information such as:
Backup clients Backup servers Storage nodes Amount of data backed up over time Configured devices Clients that are not part of the backup network Which tool should you use to gather this information?
