ABC.com has dual-mirrored core/edge Brocade fabrics. You plan to integrate an Invista instance

into this environment using a hub-and-spoke (inline) design. What is the maximum number of
edge switches that can connect to an Invista AP7600-B switch?

ABC.com uses a third-party array in their SAN with six file servers, two two-node Exchange
clusters (< 500 users), and a large Oracle database server connected to it. Total capacity on the
array is approximately 17 TB.
The customer will be deploying a Solaris-based ERP package within the next six weeks.
Performance has degraded to unacceptable levels and the customer is asking EMC to propose a
replacement of the SAN and array.
Criteria for making an EMC recommendation are ranked as.
1. Predictable, scalable performance
2. High availability
3. Flexibility of the solution
4. Expandability (disaster recovery is a future need)
5. Minimal operational disruption
6. Price
Which proposal would best meet these criteria?

You work as an administrator at ABC.com. You study the exhibit carefully.
Exhibit:

ABC.com has collected response time performance data from their CLARiiON array due to
problems they are experiencing with overall array response times. They have created a graph of
the data that is displayed in the exhibit.
The customer has a CX3-40 with 22 Windows hosts and replicates several LUNs with SnapView
periodically throughout the day. How would you explain the peak in response times given the
overall performance profile shown?

ABC.com utilizes two CLARiiON CX series arrays in their SAN environment. They have a CX3-80
in their corporate data center and a CX3-40 in their remote field office 50 miles away. The
customer is considering the purchase of MirrorView software and plans to implement a
MirrorView/S solution between sites and use bi-directional mirroring. The customer wants to use
an existing DWDM solution and share the same link with a Symmetrix SRDF solution.
What should you tell the customer?

Due to multiple clone restore problems in the past, ABC.com is attempting to implement protected
restore functionality in their CLARiiON environment. They call you to say they are confused
because they cannot find the feature listed in Replication Manager.
Where should you instruct the customer to find this feature?

ABC.com currently has an NSX attached to a Symmetrix and would like to discuss disk-based
recovery options. They have a design goal that requires a copy of the file system be accessible
read/write. This copy is independent of the production file system. In addition, the customer is out
of capacity.
What is your recommendation?

A customer has a DMX-4 with an application workload that is experiencing long response times
with write operations during month-end batch processing. The customer has observed that other
applications on the same DMX on different disks also experience long read response times during
this same time period.
What is the most likely design attribute that is responsible for this behavior?

You are preparing a preliminary migration analysis for an existing customer. The customer
currently has 20 Windows servers, 13 Linux servers, a Symmetrix 8530, a SAN, and one NetApp
filer. In addition, some of the host applications use direct-attached storage. The target of the
migration is a CLARiiON that is accessible using SAN and a NAS gateway.
Which methods of migration would be appropriate for this project?

ABC.com is concerned that their SnapView activity is negatively impacting the overall performance
of their array. The customer would also like to understand where to quickly find out how many
reads are coming from the Source LUNs as opposed to the snapshots.
Where can the customer quickly locate this information?

Your customer wants you to design the data layout for their imaging database.
The data read size and write size are 256 KB
Accesses are sequential
The application is single-threaded
Which RAID type and configuration would you recommend?
