A customer is using Replication Manager using Microsoft Volume Shadow Service (VSS) to backup their Exchange 2010 environment hosted on a Symmetrix VMAX storage array. To improve performance of backup and maintenance tasks, which allocation unit size should be used to format the Exchange database and log volumes?
How do you migrate RDM data located on a Symmetrix array?
You are planning a cold migration of a virtual machine from one VMFS datastore to another. VAAI hardware acceleration is enabled and both datastores are on the same EMC Symmetrix array.
The virtual machine has RDMs attached to it.
When you perform the cold migration, the virtual disks move to their new location. However, it appears that the RDMs have been converted into virtual disks.

Which course of action will resolve this issue?
A company has implemented Microsoft Exchange Server 2010 in an SRDF environment with replicas being taken at the disaster recovery (DR) site. During testing of this solution, they have failed over Exchange operations to the DR site. The Exchange mailbox server appears to come online, but user mailboxes are inaccessible. The Exchange Management Console shows all mailboxes marked with a small red “x” over the mailbox icons.

What is the potential problem?
Some applications running on an EMC Symmetrix VMAX array are experiencing poor performance.
A performance analysis reveals the following:
Write response time is impacted
Heat Map shows low front-end utilization
Heat Map shows high back-end utilization

What is the requirement with regards to Symmetrix gatekeeper (GK) devices?
A company intends to manage their EMC Symmetrix VMAX array with the Symmetrix Management Console Virtual Appliance (SMCvAPP) deployed on an ESXi server. What is the requirement with regards to Symmetrix gatekeeper (GK) devices?
What is the correct alignment?
A company has a SAN environment with VMFS5 hosts attached to an EMC Symmetrix VMAX experiencing poor performance. They observed that the file system subblock size is misaligned.

Which kind of application does this profile most likely represent?
When using Performance Manager to analyze an application, you notice that the application has a high amount of reads but a very low read hits. The workload is mostly random.
Which kind of application does this profile most likely represent?
What is a likely solution to this problem?
A host with an OLTP workload is configured with five standard devices on an EMC Symmetrix VMAX. In the host LVM, the storage is configured into a concatenated logical volume. The back-end storage consists of Fibre Channel disk drives. The host has two HBAs zoned to two FAs.
The workload hits a ceiling at around 66% of the peak workload requirements with high random reads. At peak times:
Disk director % utilization is low
Host port % utilization is low
Disk I/O per second is low
Current write pending count is high
