A customer is about to implement your VNX for File design for a file-sharing environment. The design specifies both NFS and Windows clients that access file systems in a multi-threaded manner. All file systems will be created using the Automatic Volume Manager. The customer is most concerned with disk efficiency, and wants to use all storage in each pool entry before creating another.
Which value would you change to meet this requirement?
A. is_greedy
B. slice
C. is_dynamic
D. stripesize
Your customer is designing a Proof of Concept with SQL Server attached to a VNX. The storage design includes seven LUNs on a RAID Group. The system is generally very heavily loaded, with a particularly high load on the cache. This is a very carefully controlled environment and your customer has asked for assistance in planning the layout of the LUN location on the physical spindles.
Where in the RAID Group would you recommend placing the two heavily used LUNs for a "short-stroked" architecture?
A. Adjacent to each other at the beginning
B. One at beginning and one at the end
C. Adjacent to each other in the middle
D. Evenly placed, as non-adjacent as possible
You are migrating a backup application that runs on physical servers to a VDC. The VDC storage is currently a VNX configured with NL-SAS drives only. Your customer is concerned about the cost to achieve reasonable performance. You are designing the VMs that will support the application.
Based on cost, which would be the first solution you would recommend?
A. VMware Paravirtual SCSI virtual adapter
B. Virtual adapter is BusLogic Parallel
C. FAST VP Pool (Flash and SAS drives)
D. SAS RAID Group
A customer has created a thin LUN, enabled compression on a LUN Pool, and installed their Exchange environment. The Exchange application is showing poor performance.
Which workload characteristic of Exchange would produce poor access times on a compressed LUN?
A. Small random writes
B. Small random reads
C. Sequential reads
D. Uncompressed or host based data
A client has asked for assistance with designing his Exchange environment. The environment today is fully virtualized and Exchange will be as well. The client is concerned about local recovery and has decided to make VMware snapshots of their VMFS File system housing Exchange. The VMware servers are all attached through fiber to a VNX.
What volume type is required to meet the customer's protection needs?
A. Virtual Mode RDMs
B. Physical Mode RDMs
C. VMFS
D. Dedicated RAID Group LUNs
A customer would like to use five Ethernet ports on a VNX to increase the port and switch availability. Two non-stackable Ethernet switches are available for the VNX and both support Full Duplex communications. How should the customer configure the VNX for the network?
A. Fail Safe Networking and Link Aggregation
B. Link Aggregation only
C. EtherChannel and Fail Safe Networking
D. EtherChannel only
A customer would like to configure their VNX for File for the highest possible level of client availability. There are five Ethernet ports on a single DataMover and a single Ethernet switch available for client communications. What availability features would you recommend to the customer?
A. Link Aggregation Control Protocol only
B. EtherChannel port aggregation and Fail Safe Networking
C. Fail Safe Networking and Link Aggregation Control Protocol
D. EtherChannel port aggregation only
A customer has a VNX system to provide storage for a VMware Cluster with five ESX hosts. Each ESX host has one dual-port FC HBA connected to two FC switches. They are using VMware native failover functionality for high availability
and load-balancing.
The customer requires higher availability for the ESX host connectivity to the storage system.
What would you recommend to the customer?
A. Use dual HBAs with dual ports on each ESX host.
B. Use a host-based load balancing solution.
C. Use high quality stackable FC switches.
D. Current configuration ensures the best availability.
Which action would be most effective in reducing the performance impact of a Snapshot on a Source LUN?
A. Using faster disks for the Source LUN
B. Using faster disks for the Reserved LUN Pool
C. Increasing the Snapshot chunk size
D. Increasing the Snapshot write-aside size
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 spindles 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 RAID 1/0 15K spindles will the transaction log volume require?
A. 4
B. 8
C. 10
D. 16
