Microsoft Lync Server 2010 Advanced Design and Deployment Set 2

A customer is migrating from a third party managed disk subsystem to an IBM TotalStorage Enterprise Storage Server. Connection of the new storage server is complete, and it has been tested on all of the nodes in the three node HACMP cluster. How does the customer migrate to the new storage server with minimum down time?

During a planning session, the customer indicates that they intend to build two independent two-node clusters (cluster 'A' and 'B') that will be provided shared storage from an IBM TotalStorage FAStT900 server. The customer intends to present 2 LUNs to cluster 'A', and 2 LUNs to cluster 'B'. All hosts will be dual attached via fibre. What additional hardware or software is necessary to make this a valid configuration?

A customer has a new computer room that will be used to house a new HACMP cluster. One of the outstanding features of the new computer room was the new large air conditioner. This unit has enough excess capacity for more than double the planned amount of equipment. Another feature of this computer room was the dual electric supplies to the room housed in two separate power panels. How would this impact the overall availability of the environment?

A customer moved their application start routines from the inittab and placed them under HACMP control. During testing, the applications did not always start as desired. What is the best practice for the application start routines?

During initial cluster planning session, a requirement is mandated that application monitoring will be used to monitor the production database and three application servers. Since all the application servers rely on the database being active, only one resource group has been planned to manage the starting/stopping of the cluster resources. How will the initial design impact the use of application monitoring?

To enhance the availability of an application running under HACMP, a decision was made to use the application monitoring facility. The application consists of several components and can take several minutes to initialize. The components use socket communication and can be initialized in any order as long as it is a serial order. The customer's concern is that if the application stop and start scripts are used during application monitoring recovery, it may take an extraordinary length of time to reset all of the application components. What can be done to ensure the best recovery time?

An HACMP cluster has three nodes of unequal size. The largest node is Node 'A'. The primary application on Node 'A' has two components. One component is memory intensive, the other is IO intensive. Nodes 'B' and 'C' are running web servers and databases that access information produced by applications on Node 'A'. The customer requires the most performance from the primary application and wants all nodes available for fallover processing. Which of the following is the best solution for meeting the customer requirements?

During a planning session, the customer indicates the need to provide high availability between a node attached to an IBM TotalStorage Enterprise Storage Server and a remote node attached to a IBM TotalStorage FAStT server with automatic fallover in the event of a disaster. Which of the following HACMP options will provide this functionality?

Due to a recent change in government regulations, a customer needs to create two independent but synchronized copies of their data. These copies must be contained in separate storage devices a minimum of 100 km apart. The customer has capacity in two systems that meet the criteria, one with SSA disk and the other is FAStT. What facility can be used to manage this issue?

A customer has two sites that are 3072 kilometers apart and wants to implement HACMP between the two locations. The nodes at each location must be capable of running the application in the event of a failure. Currently the customer's disk technology is SCSI. How can HACMP be used in this environment?
