SSI's MASTER TECHNICIAN SERIES STORING AND PROTECTING VIDEO SURVEILLANCE DATA Part 1 of 4 CALCULATING THE STORAGE EQUATION The most important and significant type of data generated by a video management solution is the surveillance video itself. The amount of video generated by a single server will vary based on number of cameras, resolution, and amount of motion, but can be several terabytes per day. The video itself poses the largest challenge to a storage system, and how the video is stored significantly impacts the performance and features of a surveillance system. One of the major barriers businesses encounter when installing a comprehensive video surveillance solution is the complexity and high cost associated with building out network, IT and storage infrastructures to accommodate rapid expansion. It's a new era of greater performance but fewer complications. Storage appliances with embedded virtual servers can take the place of dozens of physical servers to provide reliable and scalable video storage. Cost savings are realized through hardware reduction; there is an average 40% savings in power, cooling and rack space with virtualized appliances. A single virtualized platform saves in power consumption (a "green" benefit), requires less cooling and takes up less datacenter space by eliminating racks of servers. Overall, this equates to significant savings for the end user. Increased Functionality — Server virtualization platforms ofer a number of advanced features that traditional physical servers cannot. Tese features — such as fault tolerance, high availability and self-healing restarts — boost business continuity and increase uptime, critical in the world of video surveillance. Also, these very technology advances allow virtual machines to quickly recover Improved Disaster Recovery — Whatever the size of an end user's surveillance infrastructure, it is critical to have a disaster recovery (DR) plan in place to safeguard surveillance operations in the most challenging environments.

A VMS application running as a virtual server application, for example, can simply move to another physical server to provide maximum uptime for critical systems. Tis failover technology eliminates the need for complex clustering software, dedicated failover hardware, customer cables and expensive application failover licenses. Fluidity of applications across physical hardware resources may sound complicated. To the security reseller, however, it solves a major problem without additional cost. After all, every user and installer understands that hardware failures do happen in the feld. Using virtualization to ensure that these expected failures do not interrupt video storage and retrieval introduces a major beneft for those who face liability exposure, service level agreement penalties or compliance fnes if video security systems are compromised. from outages. Tis is especially critical in regulatory-driven markets such as gaming and transportation where compliance with regulations drives retention rates and constant video recording. Virtualization also allows users to centrally monitor the health and performance of recording servers to dynamically move recording applications, such as video management software, across physical servers for loadbalancing or maintenance. Tis approach automatically optimizes recording server resources, and initiates failover recovery across servers. $600M $400M $200M 0 2010 2016 External CAS Enterprise DVR iSCI SAN Embedded/Boxed Appliance NVR FC SAN PC Based NVR NAS Internal DAS External Storage Sold by VS Vendors All video storage is projected to grow through 2016.
