Gwangmyeong City (South Korea): RAIDIX Data Storage for CCTV Infrastructure


Download Case Study [PDF]

Project Environment

Gwangmyeong is a city in Gyeonggi Province, Seoul Metropolitan area, South Korea. The city houses a population of just under 500,000 people, boasts a highly developed urban infrastructure, transport system and retail/wholesale facilities including the world’s largest IKEA store (59,000 square meters).

The city leverages the value of CCTV to ensure public security and law enforcement in densely populated areas and specific facilities. Developing the video surveillance network in line with the growing requirements, Gwangmyeong City Hall was facing substantial IT challenges in terms of scale, performance and cost-efficiency/TCO. With an initial goal of servicing 200 to 500 high-definition cameras, the customer was looking for a reliable data storage system to boost retention times and data integrity.

Key Project Figures

  • Enhanced public safety
  • Greatly reduced ownership costs
  • Reliable fault-tolerant storage for critical data
  • Cost-efficient elastic scalability
  • High density and decreased rack space
  • Tech support 24/7 and regular system upgrades.

The challenge

The City Hall’s IT service built an infrastructure that allowed the CCTV system to store video content for over 30 days, however the cameras only managed standard definition video resulting in lower recognition accuracy. In addition, the City Hall employed five racks of storage hardware that almost covered an entire room space. Spearheading the transition to HD cameras for better quality and streamlined video analytics, the customer’s IT was looking for a high-performance and high-density data storage system that would handle hundreds of parallel video streams without a glitch.

In the course of transition, the customer was evaluating cost-efficient solutions to mitigate potential hardware overhead and storage costs. HD cameras generate 4x volumes of video content compared to older formats and require boosted storage capacity to accommodate the data. Gwangmyeong City Hall found themselves at the crossroads choosing between more storage racks and higher density, yet costly enterprise arrays, when RAIDIX’s partner ITServices came up with a better solution.

The solution

At the core of the data storage system sits the RAIDIX software engine. RAIDIX manages storage clusters and delivers advanced functionality to ensure optimal IOps and throughput, rock-solid fault-tolerance and universal compatibility with standard hardware. The solution supports shared SAN and scale-out NAS and major interfaces like Fibre Channel, iSCSI, and InfiniBand. As part of the solution, the RAIDIX architecture encompasses two high availability controllers working in Active/Active mode.
The technical specification of the comprehensive solution included:

  • SBB (Supermicro)
  • 16+45 (JBOD 60 1 unit)
  • Node synchronization: ATTO Fibre Channel
  • 200+ HD cameras
  • Raw size: 244TB (61 HDDs)
  • Three LUNs
  • Topology: Fibre Channel 8Gb

While the majority of RAID controllers operate with either 16 or 32 disks, the RAIDIX technology supports up to 64 drives and survives failure of 3 disks in the same RAID-group (proprietary RAID 7.3) or up to 32 disks in the array (proprietary RAID N+M).
The City Hall deploys 200+ HD cameras across Gwangmyeong. Data grabbed by the CCTV infrastructure is streamed to multiple media servers at the data center and forwarded to two ATTO switches linked via Fibre Channel 8Gb and running the RAIDIX management software.

The RAIDIX storage appliance connects to a JBOD that houses 60 disks and consolidates 244TB capacity in a single rack. For optimal availability, uninterrupted operation and timely hardware/software updates, the customer signed up for the premium maintenance plan from ITServices and RAIDIX.

“The RAIDIX-powered data storage system shipped to Gwangmyeong City Administration allows the customer to process hundreds of parallel HD video streams with no performance degradation, cut down on infrastructure expenses and improve overall system availability, density and TCO.”

Business impact

RAIDIX-powered resilient storage delivers two major winning points among others:

  • Higher density and hardware savings: JBOD 4U60 instead of JBOD 2U12, 7U instead of A RACK (22U+)
  • Direct Fibre Channel connection with no switch required.

To that end, the Gwangmyeong municipality employs RAIDIX to manage ultra-high density JBODs, avoiding the prohibitive costs of premium arrays, cabling and sprawling infrastructure. RAIDIX helps to eliminate vendor lock-in and build solid storage systems on generic industrial parts from multiple well-reputed manufacturers.

Data integrity ensured by the triple-parity RAID helps Gwangmyeong reinforce public safety and traffic regulations. Continuous local tech support preserves the peace of mind for the customer’s IT service and brings along the undisputed benefits of up-to-date storage technology.
Moreover, the RAIDIX-based system enables elastic cost-efficient scalability – a feature most valued by Gwangmyeong’s IT Dept. planning to enhance their CCTV coverage and the number of cameras by a factor of three in the coming years.
