A customer is designing an environment that utilizes thin LUNs on a pool. The customer makes capacity calculations before they create the thin LUNs, and determine that three thin LUNs are required. After the customer creates them they experience a capacity shortage.
How much overhead should the customer have calculated into the usable capacity for each thin LUN?
A. 500 MB
B. 1 GB
C. 3 GB
D. 5 GB
A customer has implemented a VNX array that hosts multiple SQL database applications, but there are significant performance issues with some of the applications. They have purchased a small number of Flash drives and have asked for your recommendation on maximizing performance using the limited number of new drives.
What suggestion would you make about using the Flash drives?
A. Disable write cache and store tempDB on the drives.
B. Remove tempDB and store transaction logs on the drives.
C. Enable read cache and store tempDB on the drives.
D. Host transactional logs and tempDB on the drives.
Your customer has a 2,000 GiB traditional LUN containing a database of customer information. Data belonging to active customers is frequently accessed, but the majority of the data is static and seldom used. Your customer wants to implement block compression on the LUN.
What should your customer be made aware of?
A. The LUN will be migrated to a thin LUN.
B. Database logs are incompatible with block compression.
C. Database tablespaces are incompatible with block compression.
D. The LUN will be migrated to a thick LUN.
A customer is experiencing performance degradation when accessing certain CIFS shares configured on a VNX for File storage system. To troubleshoot, they would like to create a report that shows a combination of CIFS and network data. What command would you recommend that they use?
A. server_stats
B. netstat -e
C. netstat -i
D. server_sysstat
A customer needs to move data from a CLARiiON to a new VNX storage system. Attempts to configure a SAN Copy session with Unisphere fail. The customer uses Navisphere Secure CLI to configure the session. The session can be successfully started from Navisphere Secure CLI but fails just prior to completion each time it is started.
What is the cause of the failure?
A. Source and target LUN IDs do not match.
B. Source is a standard LUN and the target array has only metaLUNs available.
C. Source LUN is larger than the target LUN.
D. Source LUN is RAID 1/0 and the target LUN is RAID 5.
Your customer has recently purchased a VNX to host their three Oracle RAC database environments and automated payment processing application. The RACs and application are differentiated as follows: ORA- PROD, ORA-STAGE, ORADEV, APP-PROD, APP-STAGE, and APP-DEV.
The customer has provided you with their Enterprise Storage Policy (ESP) and is requesting that you adhere to this policy when architecting their new VNX solution. The ESP states the following as it relates to Oracle database storage requirements:
All LUNs must be configured as raw devices
All LUNs must be managed using ASM
No fewer than two LUNs per ASM disk group
No more than one database per RAC per RAID Group
No more than three databases per RAID Group
All data LUNs must be 1000 GiB RAID 5
All FRA LUNs must be 500 GiB RAID 1/0
No more than eight total disks per RAID Group
No fewer than four disks per RAID Group
Based on the ESP, and assuming ORA-PROD has six instances, what is the minimum number of disks required?
A. 4
B. 8
C. 12
D. 24
A customer with a VNX configured with homogenous pools wants to upgrade the performance of their array. The customer has a limited budget.
Which approach would you recommend?
A. Create a mirrored FAST Cache
B. Create a R5 3+1 FAST Cache
C. Create a FAST VP Tier
D. create a homogeneous flash pool
Your customer has LUNs with a total size of 25,000 GiB. The total I/O load is 10,000 IOPS, with a 4:1 R/W ratio. Analysis of your customer's data indicates that data skew is 95%. 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. 5
B. 10
C. 15
D. 20
You are conducting an analysis of a Celerra system to migrate the data to a new VNX Unified storage subsystem. You want to collect statistical information about the CIFS sub-system.
Which "server_stats" statistic type would you use to get the desired information?
A. Family
B. Compound
C. Element
D. Computed
A VMware 5 customer is planning to upgrade their networking environment to 10 Gb Ethernet. They would also like to use real time vMotion to ensure balanced application load distribution throughout their environment. They are also currently running their VMware environment on 64bit, dual core processors.
What advice would you give to your customer to assist them with the upgrade of their environment?
A. Upgrade their servers to quad core CPUs or greater and ensure all servers have access to the datastores.
B. Configure NIC teaming on their servers and ensure that all VMs on each ESXi server are configured for FT.
C. Ensure all servers have multiple paths to all arrays to support VM file movement and all VMs are configured for HA.
D. Ensure that all vMotion sessions are configured for core 0 (zero) affinity and enable Direct Path I/O.
