After reviewing the design for their new VNX, your customer has requested further explanation of the hot spare algorithm used by the array. You propose the following scenario:

RAID group 200 consists of five 600 GB 10K SAS drives in a RAID 5 configuration. Within this RAID group there are three 25 GiB LUNs. One of the five drives has just failed.

In your scenario, which hot spare drive would the array first select to replace the failed drive?

Which functionality is provided by the EMC ping tool?

Your customer has recently purchased a VNX for File. Due to the budget limits, they were unable to purchase enough SAS drives to create all of their required file shares. They would like to use their NL-SAS drives but are concerned about lower performance.

What EMC solution do you propose?

Click on the calculator icon in the upper left-hand corner. A customer has a heterogeneous pool with the following configuration:

800 GiB of Flash, with 300 GiB free 12,000 GiB of SAS, with 2,000 GiB free 50,000 GiB of NL-SAS, with 25,000 GiB free The customer creates a new LUN with data placement policy set to "highest available tier". The LUN is then populated with 600 GiB of data.

How is that data distributed (numbers are approximate)?

During a design session with the customer you discover a need to replicate the source VNX to many locations for Disaster Recovery requirements.

To qualify a customer's new ESX host for VNX connectivity which data collection output should be requested from the customer?

A VNX customer has several LUNs that are experiencing some performance issues. They understand the application profile uses small-block, write-intensive, random I/O. The customer uses snapshots for these LUNs and the bandwidth to the RLP LUNs far exceeds bandwidth to the source LUNs.

Based on best practice, what is the maximum change rate percentage recommended if snapshots are used on the LUNs?

You have been working with a customer on sizing and implementing a RecoverPoint/SE CDP solution into their environment. The customer calls you, wanting to know how they can log in to the RecoverPoint application.

What IP address should they use to accomplish this?

A VNX customer is making a decision on the type of splitters to use with RecoverPoint/SE 3.x in their environment. The environment has a small number of Microsoft Windows hosts with several LUNs greater than 2 TB. After making a decision to use host splitters, the customer realizes this is not a viable solution.

Why would the customer reach this conclusion?

Refer to the exhibit.

You are using Analyzer Helper to review NAR files from a customer's VNX array.

Which characteristic is indicated by the graph?

In which section of the E-Lab Navigator would you find support statements on eligible early supported configurations?

You are sizing a new RecoverPoint/SE CRR installation for a customer. You have gathered data from their environment and have decided that they will need 142 consistency groups.

How many RecoverPoint appliances at each site must you plan for?

An EMC customer deployed their business critical applications on large AIX servers and VNX arrays. They are constructing a disaster recovery site 500 kilometers from their primary data center. The data center manager asked which EMC and Oracle features and products can be combined to provide block remote protection.

Which EMC and Oracle features and products can be combined?

Which tool is used to verify that the customer's hosts and switches are compatible with their new VNX?

What is the maximum time (in seconds) that VSS will stop Exchange I/O processing when VSS creates an application-aware point in time copy?

A customer asked for your assistance in the design and migration of their existing storage to a new VNX system. The customer provided the graphical data from their performance monitoring tool showing data IOPs for the server. The monitoring tool uses iostat which gathers data every 15 minutes.

Which primary factor should be explained to the customer when requesting alternate performance data?

Your customer has recently purchased a new VNX. They have chosen SAN Copy to migrate data from their existing CLARiiON to the new VNX.

The customer has stated that only 50% of the capacity within each of the source LUNs is actually consumed.

Source LUNs are 500 GiB RAID 5 on 1 TB SATA disks. All LUNs and RAID Groups on the source array are configured the same.

Using best practices, which target LUN configuration should you use?

You are gathering data from a customer environment. You have to process a number of configuration reports.

What tool provides a simple method of processing the data gathering configuration?

You are preparing a detailed VNX presentation for a technically-oriented customer. VNX arrays have been in their environment for over a year. One objective of the meeting is to go over historical data. The customer indicated that they would like to see Unisphere statistics as part of the analysis.

Assuming that statistics logging was enabled from day one, how long does the Unisphere GUI keep its real-time statistics?

A customer is migrating multiprotocol data off a NetApp array to a VNX. The customer wants to keep downtime to a minimum.

Which tool is best suited for this task?

A customer is looking to migrate an existing VNX gateway from a CLARiiON CX-4 backend to a VMAX.

Which migration option mitigates risk and requires the least effort?

When interviewing customer personnel, you learn of two sets of requirements:

The technical team has a specific set of requirements that they have to meet.
The manager has a financial requirement that has to be met.

As you begin to design, it becomes clear that, in order to meet the technical goal, the financial requirement will be exceeded.

What should you do?

You are planning a technical refresh of a customer's CLARiiON storage array to a VNX. They have stated that the CLARiiON seems to perform slowly and believe that they require additional disk spindles to satisfy their performance requirements.

What utility should you use to investigate performance trends?

During a data gathering meeting with a customer, a discussion about applications was presented. Most of the applications are best suited for a RAID 5 pool on the VNX. However, one of the applications has an I/O requirement for RAID 1/0 spindles.

How should the RAID 1/0 application requirement be handled?

You are reviewing log files for a customer's application using Analyzer, and note the following:

NFS write size is 8 KiB LUN Write size is 8 KiB Disk write size is 32 KiB

You can see that LUN write sizes are identical at 8 KiB.

Why is the application not writing at 32 KiB?

Click on the calculator icon in the upper left-hand corner. A customer wants to add a SnapView snapshot to a 600 GiB LUN. Captured data show that the LUN has an access rate of 1000 IOPs with a read/write ratio of 4:1, and 8 KiB IOs.

What is the expected initial bandwidth at which data chunks will be written into the Reserved LUN Pool?

A customer has two data centers located 500 kilometers apart and uses VNX arrays exclusively for block data storage in both of them. Each data center is monitored and managed by Unisphere. The customer wants to deploy an integrated replication methodology to protect his most critical data.

Which product will meet the customer's requirements?

A customer wants to use RecoverPoint/SE CRR. They have just realized that they need to use RecoverPoint write splitters, but do not understand how they work.

What does the splitter do after it intercepts a write I/O meant for a RecoverPoint Protected LUN?

A new customer is looking at purchasing two new VNXs and wants to replicate the CIFS environment.

What is a recommended configuration to have CIFS replicated?

What is the best practice for FAST Cache for component LUNs of a metaLUN source?

The customer is considering purchasing a Unified VNX and requires file system replication from multiple locations to one DR array.

Which solution should be discussed with the customer?

You have decided to use SAN Copy to perform an incremental copy migration of your customer's data.

There are 25 source LUNs; each LUN is 250 GiB in size. The target LUNs are each 300 GiB in size.

Using best practices, what is the smallest sized LUN in GiB you should use in the reserved LUN pool for this migration?
