The Storage Medium used is
of More focus than the
Quantity of Storage used. It is
no longer one-size-fits-all
“Data Deluge” is
Fundamentally Changing the
way that Storage is
Approached.
HARDWAREIntroduction
![Page 24: Big Data and Health Care](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a5299a1a28ab6c678b4583/html5/thumbnails/24.jpg)
● Provide Real-time Or Near Real-time
Responses.
● Handle Huge Data Volumes Growing Rapidly
Key Characteristics of Big Data Infrastructure:
● High processing/IOPS performance
● Very Large Capacity.
HARDWAREWhat’s Key to Efficient Data Processing?
![Page 25: Big Data and Health Care](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a5299a1a28ab6c678b4583/html5/thumbnails/25.jpg)
KEY DIFFERENTIATOR
● Big Data is Largely Unstructured.
● Unstructured Data is Immutable
● Traditional File Systems have Built-in Functions to handle Insert/Update.
● Creates a Lot of Overhead in Terms of Performance, IOs Required to
Access Data and the Ability to Scale
HARDWAREWHY DO WE NEED A DIFFERENT APPROACH?

● Objects in one Large, Scalable Pool of Storage
● Stores metadata – Information about the
object
● An Object ID is stored, to Locate the Data
● Objects are immutable
● No File System Hierarchy

HARDWAREDATA PROTECTION – WHY DIFFER FROM TRADITIONAL
APPROACHES?
![Page 33: Big Data and Health Care](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a5299a1a28ab6c678b4583/html5/thumbnails/33.jpg)
RAID (REDUNDANT ARRAY OF INDEPENDENT DISKS)● Originally Designed for Small Capacity Disks.
● Longer Time taken to Restore a Failed Drive as Capacity Increase.
● To Shorten Longer Rebuild cycles, RAID Systems Ship with Faster Processors,
Leading to High Energy Consumption.
REPLICATION
● Copies Add Additional Costs: Typically 133% or more Additional Storage is
needed for each Additional Copy
● Storage System will get More Expensive as the amount of Data Increases
HARDWARELimitations of Traditional Approaches
![Page 34: Big Data and Health Care](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a5299a1a28ab6c678b4583/html5/thumbnails/34.jpg)
How Does it Work?
● Information Dispersal Algorithms (IDAs)
separate data into Unrecognizable slices of
information.
● It is then dispersed to Storage Nodes in
disparate Storage locations.
● It can be implemented Locally or
Distributed .
● Only a Pre-defined subset of the slices From
the Dispersed Storage Nodes is needed to fully
Retrieve all of the Data.
HARDWAREInformation Dispersal - Better Approach?
![Page 35: Big Data and Health Care](https://reader030.fdocuments.in/reader030/viewer/2022032420/55a5299a1a28ab6c678b4583/html5/thumbnails/35.jpg)
● It is Resilient against Natural disasters or Technological failures, like
Drive failures, System Crashes and Network Failures.
● Data can still be Accessed in Real-time even if there are Multiple
Simultaneous Failures across a String of Hosting Devices, Servers or
Networks
● Five 9’s or More are Guaranteed with Overhead Low as 20% - As
Opposed To 3 Copies Requiring 200% Overhead.
HARDWAREBenefits of Information Dispersal

When looking at Number of Years without Data loss, with a 99.99999% Confidence Level,
Information Dispersal doesn’t even appear on the Chart because even For a Large storage amount
like 524K Terabytes, the Confidence for Years without data loss is not within anyone’s
lifetime.(Theoretically Over 79 Million Years.)

Diagnosis is a relatively straightforward
machine learning problem. Clinical
decision making is highly suited for
rule-based systems because of the
nature of the data, such as ICD-10
codes, medications, etc.,
