Your customer manages a print media environment, consisting of three Isilon clusters, which are out ofsupport. The customer would like to have access to new software releases and feature the customer'senvironment.sets. You have been asked to perform a full discovery of The customer's current Isilon clusters are as follows:
"Cust" (12 x 12000X) serves as upload media storage for different tenants.
"Working" (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it.
"Archive" (16 x 72NL + Accelerator nodes) is used to store printed content for six months.
The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forestdomains which are servicing three different environments. All servers are operating on a 1Gb network, threeVLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place forperformance measurement or optimization.
The requirements for this solution include:
* Better ROI and TCO
* Maintain same performance with possible improvements
* Renew HW/SW and get inclusive support
* Limit migrations
* Reduce space, power, cooling consumption
* Get new feature sets
* If migration required, use Parallel copy (multiple nodes, multiple threads, multiple
connections)
* Segregate tenant shares from other tenants
* Expand up to 1PB of total storage
What would you recommend be done to consolidate the three clusters into one?
* Leave the clusters as is
In an Isilon cluster, what is the relative latency of a cache hit to L1 cache versus L2 cache?
A customer wants an N+3 protection level on a cluster. What is the minimum number of
nodes that needs tobe purchased to achieve that level of protection?
A telecommunications company has a substantial amount of data. This data is being created by networkelements within their environment.
The company wants to change the way the network element's Call Detail Records (CDR) are stored andanalyzed. The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests theminto a large database. Once ingested, a query engine accesses the database and performs analysis on thesefiles. The system is functional; however, since the amount of CDRs generated will increase exponentially overthe 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 oftime 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 workwithin the Hadoop environment.
What would be the best recommendation to the customer for the workflow of Hadoop with Isilon?
