The Storage Administrator notices some available space on the PFS file system. He attempts to write a new file but is unable to do so. He checks mounts and exports and sees the file has r/w permissions.

Why is he unable to write a new file?

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

Your customer recently configured new network connections on his newly installed Celerra. He can access data on all interfaces but is reporting performance problems. Your customer sends you ifconfig outputs from the Celerra and client machines.

What could be causing his performance issues?

Your customer would like to use ATA drives for their SnapSure SavVol. The I/O access pattern on the PFS is random read. They plan to access the checkpoints randomly as well.

What would you recommend?

Your customer has recently purchased eight 146GB drives for his DMX that will be configured in a RAID5 3+1 configuration.

How would you suggest the customer configure new file systems for best performance?

Which tool should be used to copy CIFS filesystem ACL’s?

The customer would like to implement CAVA and a DHSM solution in his W2K3 environment. The customer is concerned about the time it takes to write a file to a DHSM drive on a secondary storage.

What would you suggest to address this concern?

You have set the local security policies on the source Windows 2003 server and rebooted in preparation for a CDMS migration. You log into another server as the migration user in the domain admins group. You test access to the source by trying to map to the source share and get an access denied error.

What is the cause of this error?

The Celerra iSCSI LUNs are visible on the Windows hosts. The formatting of the LUNs stops at 100% and never fully completes.

What is the issue?

Which type of data would be backed-up using a CIFS network backup?
