What is recommended SAS LCC port configuration?
A VNX storage system has four 15-drive DAEs. There are fifteen flash drives installed in a single
DAE. The customer plans to implement traditional LUNs for this configuration. What is
recommended SAS LCC port configuration?
Which statement is true?
Planning one checkpoint for each of the following filesystems…
Your customer is concerned that the memory requirements for SnapSure and Celerra Replication
on the same Celerra may affect the performance characteristics of other Celerra applications. The
customer is planning to checkpoint and replicate the following filesystems.
For planning purposes (on the Primary Celerra only), you estimate that the SavVol sizes will be
10% of the filesystem size.
Estimate the amount of memory that will be required on the Celerra for SnapSure and Celerra
Replicator.
Planning one checkpoint for each of the following filesystems
PFS1 – 50GB
PFS2 – 220GB
PFS3 – 157GB
Planning replication of the following filesystems to a remote Celerra
Replicate1 – 135GB Replicate2 – 76GB
What is the most likely cause of this failure?
A SAN administrator creates a SAN Copy session between two EMC VNX using Navisphere
Secure CLI for a single database LUN. The session starts copying but fails to complete. What is
the most likely cause of this failure?
What else could be the problem?
The JJJ Company has migrated data with sync from a UNIX file system to a Celerra and exported
the file system for Windows. They now have no CIFS access to some paths in their directory
structure, but they can still access it with a UNIX-Host. You have checked the CIFS permissions.
What else could be the problem?
What is the likely issue?
A customer uses Replication Manager Version 5 to make replicas of their Windows 2003 server.
The customer installs a new Windows 2008 server and tries to mount the replica. The customer
reports they cannot mount the replica to the new server. What is the likely issue?
Where will your customer experience the greatest performance impact with SnapSure?
Your customer would like to use SnapSure to create checkpoints of several critical filesystems
with a sequential I/O access pattern. There is the perception that SnapSure will degrade
performance for these critical filesystems. Where will your customer experience the greatest
performance impact with SnapSure?
What storage pool attribute may have caused this behavior?
A customer has used the EMC VNX AVM feature to create a number of file systems. There are
fourteen RAID 5 (4+1) LUNs presented to AVM as VNX disk volumes. After the file systems are
complete, the customer notices that all file systems are built on one 4-element stripe set.
What storage pool attribute may have caused this behavior?
What needs to be done to correct the problem?
Acme Network Corp. is using a Celerra Replicator. They are replicating five of their production
critical FS to a remote datacenter. Because of the small backup window the Storage Administrator
decides to backup the file systems on the secondary site using NDMP Backup. The NDMP fails to
backup the remote file systems of IP Replication, but there is no problem backing up the source
file systems. What needs to be done to correct the problem?

You plan to migrate from an EMC CLARiiON to an EMC VNX. The VNX will present CIFS shares
to several Windows application hosts.
What tool would you use to test the performance metrics of the CIFS shares on the new VNX prior
to the migration?
