Trailwise – Infrastructure Lessons Learned

§ Big Data means big data volume
§ Petabytes and exabytes
§ Scalability
§ 10, 20, 50, 100, ... cluster nodes
§ Costs should scale as well...
§ High demands on machine-to-machine networks
§ In Big Data for every one-client interaction, there may be hundreds or thousands of
server and data node interactions
§ This generates far more east-west (server-to-server or server-to-storage) network traffic
than north-south (server-to-client or server-to-outside) network traffic
§ And many others like integration, data protection, operation, etc.

Big Data Infrastructure Challenges

§ Infrastructure must be engineered to scale
§ The network has to provide high bandwidth,
low latency, and should scale seamlessly
with Hadoop clusters to provide predictable
performance
§ And many more, like
§ Integration with operational data systems
§ Authentication, authorization, encryption
§ Centralized management

Where to Deploy your Hadoop Cluster?
When enterprises adopt Hadoop, one of the
decisions they must make is the deployment
model. There are four options as illustrated
in Figure 1:
‡On-premise full custom. With this
option, businesses purchase commodity
hardware, then they install software and
There have existed two divergent views
related to the price-performance ratio
for Hadoop deployments. One view is
that a virtualized Hadoop cluster is
slower because Hadoop’s workload has
intensive I/O operations, which tend to
run slowly on virtualized environments.
A related and fourth area is data
enrichment, which involves leveraging
multiple datasets to uncover new insights.
For example, combining a consumer’s
purchase history and social-networking
activities can yield a deeper understanding
of the consumer’s lifestyle and key personal

There are five key areas to consider when choosing the right deployment model*:
Five key areas to consider when choosing the right deployment model:

Deployment Considerations
The second area of consideration is data
privacy, which is a common concern when
storing data outside of corporate-owned
infrastructure. Cloud-based deployment
requires a comprehensive cloud-data
privacy strategy that encompasses
areas such as proper implementation of
legal requirements, well-orchestrated
and therefore enable companies to
introduce new services and products of
interest. The primary challenge is that
the storage of these multiple datasets
increases the volume of data, resulting
in slow connectivity. Therefore, many
organizations choose to co-locate these
datasets. Given volume and portability
For the experiment, we first built
the total cost of ownership (TCO)
model to control two environments

Servers running the node processes should have sufficient memory for either HBase or for the amount of Map/Reduce configured on the server. A server with larger RAM configuration will deliver optimum performance for both HBase Map/Reduce. To ensure optimal memory performance and bandwidth, we recommend using 8GB or 16GB DIMMs to
populate each of the 6 memory channels as needed.
Network configuration
The DL380e includes four 1GbE NICs onboard. MapR automatically identifies the available NICs on the server and bonds
them via the MapR software to increase throughput.
MapR Benefit
Each of the reference architecture configurations below specifies an additional Top of Rack Switch for redundancy. make use of this, we recommend cabling the ProLiant DL380e Worker Nodes so that NIC 1 is cabled to Switch 1 and cabled to Switch 2, repeating the same process for NICs 3 and 4. Each NIC in the server should have its own IP subnet
instead of sharing the same subnet with other NICs.
HP ProLiant DL380e Gen8
The HP ProLiant DL380e Gen8 (2U) is an excellent choice as the server platform for the worker nodes.

§ Building an enterprise-class hadoop infrastructure is a challenge
§ Analyse and prioritize your requirements (business and IT) is crucial
§ Start „small fast“ with a proof of concept
§ Consider various deployment models (On-Premis,
Appliance, IaaS, PaaS, HaaS, ...)
§ The Oracle Database Appliance is a very competitive
offering – especially as extension to your existing
Oracle operational data systems
