An EMC Avamar customer has a file server with 3 million files. Using the default cache setting,
how much of the physical RAM is required on the client for the Avamar file cache?

An existing Avamar customer wants to add a new large client to their Avamar system. This is a
moderately full Avamar single-node server running in steady-state.
What is the estimated time to ingest the customer’s large file system if the size, after
deduplication, is 10 GB?

A new Avamar customer is concerned with data security since all backup data is stored on disk.
To minimize the customer’s concerns, you have recommended the encryption-at-rest feature.

What is a consideration when using this feature?

An EMC NetWorker customer is currently performing all backups to physical tape. This includes
multiple 7 TB databases with 2 weeks retention. Their current tape libraries are approaching end
of support life.
The customer has asked for an EMC recommendation that will improve operational backup and
restore reliability. What will meet the customer’s requirements?

An EMC NetWorker customer is planning on directing the backups of a database server to the
single-engine EMC Disk Library (EDL) as shown in the exhibit. The data to be backed up is
accessed by the host through a redundant connection and resides on primary storage.

Based on EMC best practice, what needs to be adjusted in the solution?

A customer is interested in implementing two DL4000 systems. One system is located at a central
site. The second is at a remote site as a target for Remote Copy operations. Policies will be
configured to replicate certain tapes to the target.
Which process is necessary to make the virtual tapes available on the target?

A potential EMC customer has a T1 circuit between their production data center and their disaster
recovery data center that are 2,000 miles apart. They currently back up their Linux systems to
physical tape using HP Data Protector. They back up an average of 20 TB each night.
The customer wants a backup solution that improves backup and restore reliability, reduces
overall costs, and eliminates physical tape. What is a recommended solution?

A customer uses EMC NetWorker on HP-UX to back up 20 TB per day to physical tape. They
currently restore 10 TB of database data twice a week. The customer needs a new backup
solution that will reduce backup and restore times and is highly available.
What is a recommended EMC solution?

A customer is interested in using a Remote Copy policy to replicate data between two single-engine EMC Disk Library (EDL) systems. The customer is concerned about the readiness of
replicated tapes in case of a failure on the source system.
What can be done to minimize the exposure on the target?

An EMC customer is evaluating a single-engine EMC Disk Library (EDL) system. They placed the
EDL on their test infrastructure and performed 15 simultaneous backup jobs. The customer is
concerned that the overall performance numbers are substantially lower than the published
numbers.
Each job is sent to a separate virtual tape at an average rate of 18 MB/s. The EDL is connected to
the SAN through two FC ports at 4 GB/s. There are a total of 15 LUNs for virtual tape storage. The
infrastructure has been certified to sustain performance in excess of the EDL’s capability.
What would you recommend to improve the overall performance?
