NO.98 A customer is evaluating Isilon and Pure FlashBlade solutions. Which protocol is available for both solutions?
Response:

NFSv3

SMBv3

NO.99 A customer has 10 nodes in a cluster using N+2 protection. What is the minimum number of nodes required to be online and in communication with one another to satisfy quorum?
Response:

NO.100 You get a call from a customer that has just added 200 user connections to the cluster. They want to know how fast they are writing data with these new users. What tool would you use to gather this information?

NO.101 A telecommunications company has a substantial amount of dat
a. This data is being created by network elements within their environment. The company wants to change the way the network elements Call Detail Records (CDR) are stored and analyzed.
The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files. The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records.
In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs. After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment.
What would be the best recommendation to the customer for the workflow of Hadoop with Isilon?
Response:

Copy the CDRs from the source to an Isilon cluster with NFS, then use Hadoop to analyze the information directly over HDFS

Write the CDRs directly to an Isilon cluster with an NFS mount, then use Hadoop to analyze the information directly over HDFS

Copy the CDRs from the source to an Isilon cluster with NFS, then ingest the information into Hadoop for analysis

Write the CDRs directly to an Isilon cluster with an NFS mount, then ingest the information into Hadoop with NFS then analyze

NO.102 A customer wishes to back up their Isilon cluster via NDMP using a software package that supports NDMP connectivity. The backup process will require the cluster to create a point-in-time copy of the directory to be backed up.
Which OneFS feature(s) will need to be licensed?
Response:

NDMP only

No additional licenses are required

SnapshotIQ only

SnapshotIQ and NDMP

NO.103 What method does the MediaScan job leverage to locate and clear media-level errors?
Response:

MD5

FEC

SHA256

CRC

NO.104 A potential customer requires 4 PB of usable capacity to store media files. The workloads are a combination of streaming video delivery and long term archive of video assets.
There is very little space available in the customer’s datacenter, so physical density is very important. The customer is concerned about performance impact and potential data loss when using 3 TB or larger drives.
What Isilon capabilities can address the customer’s concerns?
Response:

Isilon does not perform rebuilds – data reprotection is typically 2x-3x faster than traditional RAID rebuilds.N+3 and N+4 Protection Levels exceed traditional RAID6 availability.Data redistribution runs faster with more nodes in the cluster.

N+3 and N+4 Protection Levels exceed traditional RAID6 availability.Proactive hot sparing eliminates most drive rebuilds.Endurant Cache reduces the overhead for write operations.

Isilon does not perform rebuilds – data reprotection is typically 2x-3x faster than traditional RAID rebuilds.Data recovery is consistent, taking the same amount of time regardless of cluster size.Isilon ,short strokes, 4TB drives to reduce rebuild time.

Isilon nodes have more drives per rack unit so fewer shelves are required.Proactive hot sparing eliminates most drive rebuilds.N+3 and N+4 Protection Levels exceed traditional RAID6 availability.

NO.105 A customer is evaluating PowerScale and NetApp FAS solutions. They are storing many unique files and want to understand how each solution deduplicates data. What is the difference between how PowerScale and NetApp FAS deduplicate data?
Response:

PowerScale uses separate deduplication at the volume level.NetApp FAS uses global deduplication across the cluster.

PowerScale uses global deduplication across the cluster.NetApp FAS separates deduplication at the volume level.

PowerScale does not have deduplication.NetApp FAS uses local deduplication.

PowerScale uses local deduplication.NetApp FAS does not have deduplication.

NO.106 A potential customer requires 800 TB of usable capacity to store medical images for their network of health clinics. The IT department has limited staff and currently manages four storage arrays from other vendors.
During a meeting with the Director of IT you learn that the company is considering a solution from a competitor of EMC using two of the existing arrays and two new arrays.
Which Isilon capabilities would show a better ROI for the customer?
Response:

Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher.Isilon utilization is typically 80% or higher due to use of a single filesystem and virtual capacity for drive and node failures.

With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher.OneFS compression results in higher effective capacity within the cluster.Traditional clustered filesystems require 4%-10% internal overhead compared to Isilon virtual capacity.

Forward Error Correction overhead is 7% lower than traditional RAID.Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.According to an IDC study, Isilon improves IT productivity by nearly 50% compared to traditional competitors.

Isilon has 15%-20% less overhead than traditional clustered filesystems.According to an IDC study, Isilon utilization is nearly 50% higher than traditional competitors.Isilon QOS headroom and multiple node pools ensures consistent performance up to 80% utilization.

NO.107 An Isilon cluster is configured with SmartConnect zones using dynamic IP address allocation. Failback is enabled. What happens to the IP address in the event of a node failure?
Response:

The connection must be re-established by the client.

IP address is moved to a new node and the connection continues.

IP address is moved to a new node but the connection does not continue.

IP address is no longer used and a new connection needs to be made.
