The rapid evolution of cloud computing and the Internet of Things (IoT) is
creating new opportunities and business models around the world. Technology
innovators are imagining everything from smart cities, smart homes, and connected
classrooms to energy optimization systems, autonomous cars, personalized medical
devices, and more. Millions of new connected devices with their multiple sensors
will inevitably unleash a tidal wave of data flowing through the IoT, raising issues
such as network congestion, bandwidth prioritization, data resilience, and cost. This
is why Edge and Fog computing are gaining momentum. With reliable and always-
available local storage, Edge and Fog computing have the unequivocal advantage
of being able to analyze data locally, which resolves many of these critical issues.
The benefits of Edge and Fog computing include:
Reduce bandwidth and power requirements
– Utilizing storage at the edge of
the cloud eliminates the need for constant connectivity to the cloud. This reduces
network congestion and the need to power always-on connectivity components.
Reduce connectivity expenses
– Data flow to and from the cloud can be throttled
to occur only when necessary or most economical to do so.
Real-time analytics
– The ability to interact with edge storage eliminates the latency
that may occur when retrieving data from remote sources, enabling the true real-
time analysis and processing that is key to many mission-critical applications.
Enhance operational reliability
– Edge storage can be configured for redundancy,
ensuring access to critical data even when communication channels to the cloud or
IoT are compromised.
Applications:
•
IoT / Industrial Gateways
•
Surveillance and Camera Systems
•
Access Control Systems
•
Networking and Communications
•
Offline Data Collection Systems
Smart Features:
•
Health Status Monitor:
Track the health
and life of your critical storage
•
Host Lock:
Storage attaches to a single
device and thereafter be used only
with that device
•
Programmable Identifier String:
Program a unique identifier on the
card for remote traceability
•
Secure Firmware Update:
Enables
remote maintenance of the storage
solution
The SanDisk® write-intensive flash solutions are proven to deliver a set
of distinct benefits:
High endurance
–
Our write-intensive NAND flash technologies are built for the
rigors of interaction at the edge, supporting far higher numbers of write cycles than
commodity flash technologies. This level of endurance is crucial to ensuring data
integrity and a low cost of ownership over the lifetime of a system.
Future proof
– A wide range of dependable storage solutions can be incorporated
into a single technical architecture to support diverse use cases; for example, the
same IoT gateway, with differing storage configurations, could be deployed in
environments ranging from home to factory to a smart city infrastructure.
Cost effective
–Vertically-integrated manufacturing process enable us to create
flash solutions that are cost effective and optimized for write-intensive applications.
Longevity
– Having the peace of mind that your data, whether being recorded on
or off-line, will be kept intact until it is retrieved or transmitted to the cloud.
