PowerEdge R740xd2 for Video Surveillance
Tech Note by:
Tad Walsh
SUMMARY
The new PowerEdge R740xd2
is an enterprise content server
optimized for data intensive
workloads including video
surveillance.
The number of video cameras
installed and the video
resolution (number of
megapixels) are both increasing
exponentially, driving
requirements for a server with
very large internal storage, like
the R740xd.

user requirements, taking the
guesswork out of acquiring,
implementing and using the
solution
Video surveillance continues to prove its key role in protecting people and
assets. It has been estimated that in 2017 alone, 127 million network and
CCTV surveillance cameras shipped worldwide.

Organizations are
increasingly turning to digital Internet of Things (IoT) surveillance infrastructure
to improve reliability, responsiveness, and manageability. Along with this trend
of rapidly growing use of video surveillance comes the question of how to store
the huge influx of video. Compounding the issue even further, the quality
(resolution) of camera technology is advancing, with an estimated 70% of
cameras now capturing images at moderate to high resolution, requiring more
infrastructure to store video.

As a result, storage needs for enterprise
surveillance storage are forecast to grow at a 42% compounded average
growth rate (CAGR) from 2016 to 2021.

This exponential growth of required capacity is being driven by applications
including Safety and Security; Counterterrorism; Compliance; Digital evidence;
Facial recognition; Anomaly detection; Anti-litigation; and Fraud/Loss
prevention. Moreover, these applications have been and are being further
implemented across many sectors, including city surveillance, government
sites, bank branches, retail shops and outlets, manufacturing facilities, hospitals
and schools as well as business buildings and campuses.
PowerEdge R740xd2
Assisting in solving the need for a right-sized platform for storing and
processing video, the new PowerEdge R740xd2 is an enterprise content server
optimized for data intensive workloads. Bringing storage closer to compute, the
R740xd2 is a 2-socket, 2u platform with up to 26 drives for high-capacity
internal storage. A single R740xd2 can store up to 364TB of data in 2u, or up to
500,000 hours of HD video content. By extension, a standard 42u rack in a
data center, full of R740xd2 servers, can to store up to 7.2PB in that single rack.

Beyond its huge storage capacity, a key feature of the R740xd2 is its
expandable chassis, which permits easy access to two drive carriers, each with
12 drive bays, as shown in Image 2 on the next page. This ease-of-access
serviceability helps to ensure uptime, making the R740xd2 an excellent fit for
data-heavy workloads including media streaming, software defined storage,
messaging, cost-effective Hadoop, and the afore-mentioned video surveillance.
