Which command is used to register PowerPath/VE licensing on a vSphere ESXi host?
You have just upgraded a vSphere environment to use PowerPath/VE instead of NMP. The next step in your installation is to license PowerPath/VE.
Which command is used to register PowerPath/VE licensing on a vSphere ESXi host?
What is the minimum configuration of DRV devices that the administrator needs to create?
A storage administrator is configuring Optimizer on an EMC Symmetrix VMAX array. The array is configured entirely with RAID 5 (3+1) devices. All devices are 8 GB and all devices are R1 devices with SRDF/A mirrors on a remote array.
Optimizer has completed the first cycle of performance analysis and has recommended a large number of device swaps to balance the activity on the array. The storage administrator has been asked to minimize the time it takes to complete all the swaps.
What is the minimum configuration of DRV devices that the administrator needs to create?
In an SRDF/Star environment, which event requires an unplanned switch of the production workload?
In an SRDF/Star environment, which event requires an unplanned switch of the production workload?
When do they need to run the symstar reset command?
A company has three data centers that they use to run Concurrent SRDF/Star. All links between the workload and synchronous target sites were temporarily unavailable. They are unsure about the sequence of actions during the transient fault recovery process.
When do they need to run the symstar reset command?
Which migration approach meets all the objectives?
A system administrator needs to migrate all virtual machines in a vSphere datastore from an EMC Symmetrix DMX3 to a VMAX. The virtual machines will be migrated individually to minimize the impact to the ESX hosts. The virtual machines must remain online during the migration.
Which migration approach meets all the objectives?
What is the best way to provide predictable and controlled service levels for the production workloads?
Multiple production workloads on an EMC Symmetrix array experience performance issues during the backup window. Even though backups are written to SATA devices and production workloads reside on EFD and FC devices, response times for the production hosts degrade during the backup window and quickly recover thereafter.
During the backup window, the Symmetrix is consistently approaching the system write pending limit. What is the best way to provide predictable and controlled service levels for the production workloads?
Which storage allocation will provide optimal performance and scalability?
You are planning the deployment of a VMware vSphere environment with EMC Symmetrix VMAX arrays. Each ESXi cluster will host at least 100 virtual machines.
Which storage allocation will provide optimal performance and scalability?
Which two thin pool parameters should be used?
You work in the SAN engineering department for a company that has deployed their Microsoft Exchange 2010 application on EMC Symmetrix VMAX storage arrays across multiple site locations. The VMAX storage arrays utilize SRDF for disaster recovery. You are required to enforce thin pool utilization limits to avoid any performance implications that could arise from over-subscription.
Which two thin pool parameters should be used?
How should the metavolume be configured for redo logs?
A database administrator is implementing a new production database in Oracle 11g for Oracle RAC hosts attached to an EMC Symmetrix. The storage for the redo logs need to be provisioned.
How should the metavolume be configured for redo logs?
