A customer has recently implemented Microsoft Exchange 2010 on a VNX storage system that hosts a variety of application servers. The Exchange implementation is currently using RAID 5 striping metaLUNs across multiple RAID Groups.
They are using FAST Cache for the database volumes, but not FAST VP.
Performance has been significantly diminished.
What would you recommend to the customer?
A. Implement a RAID 1/0 configuration for the logs.
B. Implement FAST VP with the Auto-Tiering Policy.
C. Combine log and database volumes in a storage pool.
D. Place log and database volumes on separate metaLUNs.
Your customer has LUNs with a total size of 20,000 GiB. The total I/O load is 15,000 IOPS, with a 4:1 R/W ratio. Analysis of your customer's data indicates that data skew is 90%. RAID 5 is used exclusively in the environment. How many 200 GB Flash drives would be needed to handle the load of the working data set?
A. 10
B. 15
C. 20
D. 25
A VNX storage system is being configured to provide storage for an Exchange 2010 implementation for 2,000 users. iSCSI will be used for connectivity between the servers and the array. Each server has two, dual-ported NICs. Based on EMC best practices for availability and redundancy, how should the interconnectivity be configured?
A. Configure each iSCSI NIC to two iSCSI ports, one on each SP.
B. Configure both iSCSI NIC to all four of the available iSCSI ports on the array to ensure maximum throughput and fault tolerance.
C. Configure each server NIC to both ports on the SP and enable link aggregation to increase throughput.
D. Configure one NIC to SPA and the other to SPB and install EMC PowerPath to enable load balancing and failover
You are working with a customer to design a VNX for Block solution for their SQL database. They currently have a CX4-480. In the past they have co-located their database and log files. In the new VNX design, the database will be placed in
a FAST VP enabled pool. The transaction logs will be placed on a traditional RAID Group. Your customer needs help determining the number of IOPS they need to satisfy the needs of their transaction logs.
You know the following:
Transaction period: 8 hours (business day)
Throughput during transaction period: 240 GB
How many IOPS will the transaction log volume require?
A.
273
B.
546
C.
1092
D.
1419
A customer with a VNX for File system has a mix of Windows and Linux clients. The Storage Administrator wants to track and examine different types of correlated statistics for their file system read and write operations. Which correlated statistic can accomplish this job?
A. fs.qtree
B. cifs.client
C. nfs.client
D. fs.client
You are conducting an analysis of a Celerra system to migrate the data to a new VNX Unified storage system. You want to measure the current connections for the CIFS/NFS protocol. Which "server_stats" statistic type would you use to get the desired information?
A. Fact
B. Counter
C. Element
D. Correlated Set
Your customer wants to use a SnapView snapshot as part of their backup strategy. You need to determine whether or not the proposed RLP configuration will meet the performance requirement. The source LUN performs 400 random 8 KiB IOPS, with a 3:1 R/W ratio.
At what rate is chunk data written into the RLP when the session starts?
A. 800 KiB/s
B. 6.25 MiB/s
C. 7.8 MiB/s
D. 12.5 MiB/s
A storage administrator with a VNX Unified solution is using the CLI to monitor the daily storage performance. They must type long commands to examine the statistical types and names to get the desired results. You have been asked to accelerate and ease the monitoring tasks.
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 company needs to create clone LUNs on a VNX storage system. These LUNs will be used by Replication Manager to back up a Microsoft Exchange server database and log LUNs. Where must the clone LUNS be created to have the least impact on the Exchange servers?
A. In a RAID Group shared with another application
B. In the same RAID Group as the Exchange databases
C. In the same RAID Group as the Exchange logs
D. In their own RAID Group
A customer is supporting 800 Exchange users on a VNX5700. The users are divided among four Exchange storage groups using a total of eight LUNs each for data and logs and two LUNs for a cluster quorum disk and MSDTC. The
company purchased a VNX5300 for its remote site. The company is using MirrorView/A with consistency groups to ensure consistent point-in-time recovery. The Exchange LUNs have been added to the consistency group, but the
administrator is having trouble adding the quorum and DTC LUNs.
What should the administrator do?
A. Create a second consistency group for the quorum and DTC LUNs
B. Create ten consistency groups (one for each LUN) and ensure that the update frequency is the same for all groups
C. Evenly distribute all LUNs across both SPs before adding them to the consistency group
D. Fracture all mirrors before adding them to the consistency group
