A customer has a number of hosts that generate 1200 IOPS, each with a block size of 4 KB. A Fibre Channel port on the storage array has a maximum I/O rate of 6,000 IOPS with a 4 KB block size.
What is the maximum number of hosts the customer should attach to one Fibre Channel port?”

A customer has various models of enterprise arrays and would like to deploy blockbased storage virtualization for common management of their environment. Many of the applications on the storage are mission critical and therefore require highavailability components.
In addition to the data path cluster and control path cluster being physically dispersed, which other Invista feature addresses the customer’s requirement?

A customer has 35 UNIX servers that use a combination of directattached storage and a small SAN storage system that supports 10 servers. The SAN provides single port access to the servers.
The EMC sales team would like to displace the current SAN storage vendor and increase the utilization of SAN storage for this customer. The team intends to propose redundant fabrics and the use of PowerPath.
You need to determine the number of HBAs that the customer will require in each server.
Which information do you need to collect?

A customer has a centralized tape backup infrastructure and is looking for recommendations that will enable them to meet a new recovery time objective of four hours.
What is a key design criterion in recommending a solution to meet the recovery time objective?

A customer has recently added four Symmetrix arrays and six CLARiiON arrays to the SAN environment. EMC ControlCenter allocation tasks for the Symmetrix storage now run significantly slower.
Production server access to the Symmetrix and CLARiiON arrays has not changed.
What is a likely cause of the problem?

A customer’s fabrics consist of MDS9509 switches with two additional 16port FC cards in each switch. Which module would you need to add in each 9509 switch to provide Invista virtualization?

A customer is growing rapidly and expanding to new geographies. The current headquarters is located in London. They plan to create seven regional offices across France, Germany, and Luxembourg that are between 800 and 2,000 km apart from each other. Each regional office has a data center that will serve between four and six branch offices located between 30 and 200 km away.
At the close of business each evening, the customer shuts down their primary application and transmits new information to each regional office. The amount of new information sent from the headquarters office each night will be between 0.5 and 1.5 GB. Later each night, an application at the regional offices will read the data from the headquarters office and generate approximately 50 MB of new information appropriate to the branch offices.
What is the most costeffective solution that you could recommend for the customer?

A customer with a SANattached CX340 needs to add 10 test servers to the environment. They want to use iSCSI to attach the servers. They also want to boot the hosts over iSCSI from the CX340.
Assume there is available disk space and iSCSI connectivity into the SAN. What would you verify during planning and design for this project?

Due to multiple clone restore problems in the past, a customer 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?

A customer tells you that their CX340 has suddenly developed a performance problem.
Yesterday, they added a file server to the SAN and created a metaLUN from unallocated space in the array to provide the capacity needed for their file shares. Now, their Exchange server is experiencing higher than normal disk queue lengths and performance is degrading rapidly.
What is the first thing you should have the customer investigate before calling EMC Support?
