You are designing a MirrorView/S implementation for ABC.com. Which CLARiiON MirrorView/S
feature prevents a full resynchronization of the mirrored LUN in the event of an SP failure and
remote LUN fracture?

ABC.com needs to replicate data and CIFS server information from one location to another.
They currently do not have any EMC equipment onsite; therefore, there is no existing technology
to leverage. The Ethernet network is performing within normal specifications. What do you
recommend as the most cost-effective solution that supports asynchronous business
continuance?

A storage administrator asks for help in redesigning the backup environment. The current
environment has a CX4-120 that hosts data for multiple applications. The CX4-120 has 120 disks
and is at 75% capacity utilization. Performance statistics from Navisphere Analyzer show that the
CX4-120 is consistently at 75% utilization for all resources.
What should your next step be?

Which customer environment would benefit the most from Solid State disks?

ABC.com has asked you to design a NAS solution for their file sharing environment that will
include SnapSure technology to complement their backup strategy. The current storage
environment for file system usage is 5 TB. The customer expects a 10% rate of change per
checkpoint and expects a total of 20 checkpoints.
How much additional space is required for the checkpoints?

A CLARiiON customer maintains a logical network for management of all their infrastructure
devices. They are concerned that individuals who are authorized to manage network and server
devices will be able to connect to the CLARiiON array and cause them to fail their security audits.
How should the customer prevent unauthorized connection to the CLARiiON array?

ABC.com currently uses EMC ControlCenter to manage a number of servers, switches, Fibre
Channel arrays, and NAS devices. The EMC ControlCenter configuration includes a single Store
and one Storage Agent for NAS.
What can be done to change this environment to accommodate a large number of new NAS
devices?

ABC.com’s storage environment is organized into four single-director fabrics, one each for the
Engineering, Marketing, Sales, and Finance divisions. The directors are MDS-9509s populated
with several switch modules providing 64 switch ports in each director.
Hosts and storage frames connect to each fabric with no more than 70% of available ports in use.
There is complete isolation between the four SAN islands.
With the planned rollout of new cross-functional applications, the customer needs hosts in each
fabric to access storage in the other three fabrics. It is acceptable for host-to-storage traffic to
traverse up to two hops.
What is the most efficient and least disruptive SAN solution that would meet this need?

A customer has an Oracle E-Business Suite environment running on Oracle databases. Their data
is growing more quickly than anticipated, and they have asked you to resolve scalability issues.
The current environment is a Fibre Channel SAN.
The primary decision factors in this solution, in order of importance, are:
1. Price
2. Scalability
3. Ease of maintenance
4. Minimal operational disruption
Which solution would best meet the customer’s requirements?

n a core/edge fabric, 16 ports of a DMX-4 950 storage array are connected to the core director.
The fan-out is eight HBAs per storage port, producing a total of 128 HBAs serviced by this array.
There are 6 edge switches in the fabric.
What is the EMC recommendation for the minimum number of ISLs in this fabric?
