Infrastructure components

Underpinning some of the joint solution architectures with ISS and the core elements of the Dell Technologies portfolio, these solutions are designed to allow customers to grow and thrive in a multi-cloud environment and address digital transformation within their organization.

Dell VxRail, a hyperconverged infrastructure (HCI) system jointly engineered with VMware, is the easiest and fastest way to extend a VMware environment. Powered by VMware vSAN and managed through the VMware vCenter interface, VxRail provides a consistent operating experience. An HCI system includes, at a minimum, compute, software-defined storage, and virtualized networking, and can run on standard commercial servers. The underlying resources are abstracted and pooled together, which allows them to be dynamically allocated to applications running in VMs or containers. The components that make up a VxRail configuration include:

• Compute: Dell PowerEdge servers
• Storage: VMware vSAN
• Hypervisor: VMware vSphere
• VxRail manager: Plug-in for VMware vCenter

PowerEdge servers are offered in this Dell Validated Design as a stand-alone configuration. To enable future growth and to adapt to changing application demands, PowerEdge servers offer adaptive computability depending on server application. The intelligent autonomous compute infrastructure of PowerEdge servers features iDRAC (integrated Dell Remote Access Controller) and OpenManage Enterprise. These features help customers simplify their IT infrastructure by automating the entire server management life cycle. The features also provide comprehensive monitoring of health status, statistics, connectivity, and system performance utilization.

Proactive resilience is built into each PowerEdge server to protect, detect, and recover from cyberattacks—ensuring security from build, to delivery, to retirement.

Based on these pillars—protect, detect, recover—PowerEdge servers are designed to address customers' most challenging workloads, working autonomously and collaboratively across all their IT environments.

Dell PowerEdge XR ruggedized servers

Industrial-grade PowerEdge XR servers are built to withstand the extreme heat, dust, shock, and vibration of factory floors, construction sites, mobile command centers, and other extreme environments at the network edge. These ruggedized servers help cities capture and process more data at the edge. The servers have advanced customization and enterprise capabilities, and performance that thrives in harsh edge environments across the city.

Figure 6.   Dell PowerEdge XR11 server

Figure 7.   Dell PowerEdge XR12 server

PowerEdge XR series servers are built using a cyber-resilient architecture and include a comprehensive systems-management solution. The servers support multiple GPUs, which help drive powerful analytics use cases at the edge, which reduces the time to insights. Urban mobility solutions need local compute to be implemented at traffic intersections to process video streams and generate insights in real time. For such requirements, the PowerEdge XR servers are highly suitable for the analytics workloads and for outdoor environment use.

Dell PowerScale, one of the most flexible scale-out NAS solutions, is flexible and reliable at any scale. Regardless of the type of data, where it lives, or how big it gets, your data lake always stays simple to manage, grow, and protect, and simple enough to handle the most demanding workloads of today and tomorrow.

Dell PowerScale NAS is designed and developed for storing, managing, and accessing digital content and other unstructured data. A PowerScale clustered storage system is composed of three or more nodes. Each node is a self-contained, rack-mountable device that contains industry-standard hardware such as disk drives, CPUs, memory, and network interfaces. These nodes are integrated with the proprietary OneFS operating system, which is a distributed, networked file system that unifies a cluster of nodes into a single shared resource.

Figure 8.   Dell PowerScale

PowerScale is uniquely differentiated from traditional storage to enable organizations to manage high volumes of video data with greater reliability and scalability. With traditional NAS solutions, the larger the data environment becomes, the more complex and time-consuming it is to manage the growing number of storage silos. At some point, system performance begins to degrade. PowerScale OneFS is a single file system with single namespace, which enables all camera streams to share a single volume—thus saving time during the initial set-up. Isilon enables organizations to build a scale-out data lake where they can store their video data at lower management costs and eliminate islands or silos of storage. For the urban mobility solution implementations, PowerScale can be used to persist the video recordings from multiple sites at a central storage that includes high availability.

Dell ECS is a complete software-defined cloud storage platform that supports the storage, manipulation, and analysis of video security and unstructured data at massive scale on commodity hardware. ECS is designed to support the mobile, cloud, and big data workloads that are similar to large-scale video management workloads.

Figure 9.   Dell ECS

ECS provides multiprotocol access where data ingested through one protocol can be accessed through others. Data can be ingested through S3 and modified through NFSv3 or Swift, or you can choose from many other protocol options as needed.

Dell GeoDrive provides a local file system interface through which you can store and retrieve files on an ECS platform. GeoDrive provides fast and transparent access to ECS. It does not require complicated shares, mount points, or API development. Since GeoDrive presents an ECS bucket as a local drive in Windows, users and applications can store content in the cloud using existing applications that are written for Windows, with no additional IT or infrastructure cost. This architecture is used widely to leverage ECS as a tier-2 storage system for video management systems that are required as part of the urban mobility solutions.

ISS SecurOS modules

ISS SecurOS is a leading video management and analytics platform designed to create complex security systems of any scale, from local sites to global distributed systems (smart cities).

The software platform provides:

• Data gathering
• Display and recording
• Processing
• Systematization
• Storage and management of video and audio data
• Data from video analytics subsystems, integrated systems, and related information

SecurOS provides a necessary integration mechanism to ensure interoperability with third-party systems and data transfers.

The ISS video analytics modules provide clarity on the images that are captured by video, converting them into data that is relevant to security and mobility-related scenarios which generate alerts to administrators to offer immediate response to different situations. Examples include blocking an exit, starting a recording, triggering an alarm, or automatically calling authorities.

The Dell Validated Design for urban mobility solution consists of the following SecurOS software modules:

• Monitoring and control center
• GIS map layer
• Dispatch center

Monitoring and control center

SecurOS monitoring and control center (MCC) provides the monitoring and management of the complete security infrastructure of multiple local sites from a single command center. SecurOS MCC is an excellent solution for customers with multiple geographically disparate sites or business facilities that are spread across a vast area. SecurOS MCC allows for the federation of remote independent sites as if they were part of a single virtual system. This federation option allows for a more streamlined workflow and globalizes security operations to make security personnel more productive and better informed. The solution ensures uninterrupted operation of the integrated dispatcher service, including situational monitoring and management of video surveillance systems at remote sites.

Figure 10.    SecurOS MCC interface

The key capabilities of the monitoring and control center module include:

• Robust hierarchical architecture
  SecurOS MCC aggregates data from several monitoring centers into a top-level monitoring center. Remote sites themselves can be globally disparate, of different sizes, and running different editions of SecurOS.
• Several recording options
  The solution supports working with recorded video in the following ways:

• Administrators can view recorded video from remote sites.
• The SecurOS Archiver module can run on the MCC server and provide redundant recordings.

• Analytics support from local sites
  Receive all analytics events (face recognition, license plate recognition, tracking kit, and so on).
• High efficiency
  Connect multiple remote cameras and receive live video streams or archive video from any remote security systems. The system monitors hundreds of remote cameras simultaneously on one MCC server.
• Easy and flexible configuration
  An easy manual or automatic update of the configuration of a monitoring center in case of a change in the remote system configuration. Users can choose certain areas (sections) of local sites to control.
• Failover cluster
  SecurOS MCC can be implemented using SecurOS Native Failover to maintain high availability of the system. The SecurOS Failover can be configured using a cluster (three or more servers) or 1-to-1.

The SecurOS GIS is a tool for visualizing the location of security devices, such as cameras, two-way communication devices, access control (ACS) devices on a GIS map. SecurOS GIS can also prompt processing of alarm events coming from these devices.

The module monitors large and extended areas with thousands or tens of thousands of devices in the SecurOS distributed security system and keep track of events that threaten the safety of sites and people. Being a native system to the SecurOS video management platform, SecurOS GIS supports the Media Client, which is a SecurOS interface for working with video and audio data. Pairing the interfaces allows the user to respond quickly to incidents.

Figure 11.    SecurOS GIS interface

Some of the key functionalities of this module include:

• Searching for a device and browsing to the selected device on the map
• Viewing information about the device (object ID and type, status, being bound to a layer, and the geographical coordinates of the current device location)
• Switching to video playback
• Orienting the camera on the map (manually) by its actual field of view

Dispatch center

The SecurOS Dispatcher is a platform for real-time, centralized monitoring, automated incident management and alarm management, as well as security-related processes at large infrastructure facilities.

The platform ensures the operation of hierarchically organized dispatch services and their quick interaction with field teams and emergency services through a single interface. Based on the SecurOS platform, the dispatcher is the only application in its class to be unified in a single vendor offering.

Figure 12.    SecurOS Dispatcher interface

The key capabilities of this module include:

• Twenty-four hour centralized control of all the safety and security systems in a facility.
• Continuous recording of incidents originating from SecurOS video analytics detectors and SecurOS-integrated sensors.
• Incident management through a user-friendly interface that includes automation tools and a decision-making support system.
• Long-term storage of incident information.
• Logging of operator actions when they perform routine incident processing procedures.
• Generating reports on incidents and operator actions for further analysis and managerial decisions.
