A customer's EMC VNX supports several Windows and UNIX application servers. The customer is concerned about VNX performance. By monitoring their switches, they notice there is heavy traffic between the servers and the VNX. On the VNX, the hard disks seem to be heavily accessed.
The customer wants to identify which application server workload type may be causing the observed behavior. What compound server_stats command do you suggest?
A. cifs-std and nfs-std
B. cifsOps-std and nfsOps-std
C. diskVolumes-std and netDevices-std
D. cifs and nfs
A customer plans to migrate from an EMC CLARiiON to a new EMC VNX. They want to migrate some of the CLARiiON LUNs to thin LUNs on the VNX. Which SAN Copy configuration will allow them to avoid a fully provisioned thin LUN?
A. Push from thin LUN to thin LUN
B. Pull from thin LUN to thin LUN
C. Push from traditional LUN to thin LUN
D. Pull from traditional LUN to thin LUN
You are setting up Perfmon to record the number of I/O per second for a customer's clustered SQL Server prior to a migration to an EMC VNX. Which Perfmon counter should you add to the log view to obtain this information?
A. Logical Disk\Disk Reads/sec and Logical Disk\Disk Writes/sec of the database and log LUNs
B. Physical Disk\Disk Reads/sec and Physical Disk\Disk Writes/sec of the database and log LUNs
C. Logical Disk\Disk Reads/sec and Logical Disk\Disk Writes/sec of the database LUNs
D. Physical Disk\Disk Reads/sec and Physical Disk\Disk Writes/sec of the database LUNs
A customer plans a CIFS DR solution for a Windows-only environment connected to an EMC VNX for File. The customer has the VNX antivirus solution implemented on the source site. The customer asks you if there are additional considerations regarding antivirus they need to account for in their CIFS DR solution. What do you advise the customer?
A. A global CIFS server will need to be configured on the VDMs CIFS server that is replicated to the destination site to provide antivirus protection during failover.
B. A global CIFS server will need to be configured on a physical Data Mover on the destination site to provide antivirus protection during failover.
C. The CIFS DR solution is not compatible with the VNX antivirus feature at either the source or destination site.
D. The destination site is protected by the source site VNX antivirus feature during failover events.
A customer plans to migrate their virtualized server environment to a new VNX array. They are concerned their storage pool configuration could be compromised by their varied server workload profiles. What vSphere v5.0 feature would you discuss with the customer to address their concern?
A. Clustered Datastore Affinity
B. Raw Device Mapping
C. Native Multipathing
D. PowerPath/VE
A customer is implementing an Oracle database on an EMC VNX. Due to cost constraints, the customer cannot dedicate physical disks for the redo logs. How can the disks be laid out to reduce the probability of hitting the VNX write pending limit?
A. Use a striped metavolume
B. Use concatenated disks
C. Use a large RAID 5 LUN
D. Use a large RAID 1/0 LUN
A Storage Administrator with a VNX Unified solution is using the CLI to monitor a highly specific view of daily storage performance. They must type long commands to examine the desired statistical information. You have been asked to accelerate this task.
What is the most suitable solution?
A. Create user-defined statGroups
B. Use Unisphere Statistics for File
C. Use Celerra Monitor Tool
D. Collect statistics from log files
A customer has a highly active ordering application with a R/W ratio of 2:1. The application peaks at about 16,000 application IOPS during the day.
What is the minimum required number of eMLC Flash drives and 10K rpm SAS drives needed in a R5 Storage Pool to meet the performance requirements?
A. 80 SAS drives, 5 Flash drives
B. 95 SAS drives, 5 Flash drives
C. 140 SAS drives, 5 Flash drives
D. 165 SAS drives, 5 Flash drives
A Storage Administrator would like to use Manual Volume Management to create file systems for their Oracle database log files.
Which volume configuration is suitable for storing log information?
A. disk > meta
B. disk > stripe > meta
C. disk > stripe > slice > meta
D. disk > slice > stripe > meta
Refer to the exhibit.
LUN 30 is a 50 GB LUN on a 4+1 R5 group consisting of 300 GB drives. It is the only active LUN. What can you infer about the I/O access pattern to LUN 30?
A. I/O is very random.
B. I/O is largely sequential.
C. Locality of reference is high.
D. Locality of reference is low.
