3. Shared, External IP Storage Product Requirements

3.1 Requirement Overview

Intransa EdgeBlock shared, external IP storage will provide the features, functions, and basic capabilities required by the cameras, DVRs, NVRs or the Video Management System application, and is simultaneously sharable by multiple “host” servers or NVRs running the Video Management System. 3.2 Scalability The shared, external IP storage must be cost effective from a small to large deployment. It must be able to scale easily, from support for a single DVR or NVR with a few cameras, to grow to support hundreds of cameras and dozens of DVRs and NVRs, with days to weeks to months of retention and instant playback. This will allow support for future growth and changes in requirements, without replacing the physical storage infrastructure. Storage capacity of the shared, external IP storage should grow modularly from as little as 6TB of RAID protected, hot swap disk drives to 51TB (1.5PB). The security practitioner or operator must be able to increase storage capacity without interfering with the work of the Video Management System or DVR application. Such non-disruptive upgrades allow the addition of capacity to the shared, external IP storage system without halting video recording/playback operations. 3.3 Connectivity The shared, external IP storage must support standard 1GbE Ethernet infrastructure for inbound connectivity from IP cameras, DVRs, NVRs and other IP network enabled devices. 3.4 Administration and Management The shared, external IP storage must be physical security oriented and easy to use and monitor by security practitioners and operators, without specialized IT knowledge. The shared, external IP storage should be easy be maintain, with a configuration and administration interface that can be set up and running in just a few minutes.

EdgeBlock shared, external IP storage systems can grow capacity for video retention by adding up to three individual Storage Expansion Enclosures (SEEs) without requiring additional, unneeded system performance or a forklift upgrade and replacement.

� Web Based Access The shared, external IP storage should provide a Web-based browser access (such as by Microsoft Internet Explorer) GUI that can be integrated with the existing video management system GUI. A single image does not represent a GUI with access to all enclosures but rather the ability of any interface/enclosure to access data across any other enclosure.

� Alerting

The shared, external IP storage must provide alerts to the user interface GUI, through email/pager connections, and through SNMP to management frameworks. At a minimum, alerts should be issued by the storage system for system failures, component failures (e.g. disk crashes), “failing” conditions, threshold maximums and pre-set minimum available space, performance, or other system conditions.

� Reporting

The system should provide reporting for routine metrics including capacity utilization, CPU utilization, storage volume configurations, disk groups, etc. that the security practitioner or operator can use to easily understand storage system status.

3.5 Storage Utilization and Operation The shared, external IP storage must provide the best storage capacity utilization, leveraging advanced features that include load balancing, global hot disk sparing, storage consolidation and virtualization. The shared, external IP storage should not regularly require system shutdown or impose major performance degradation for routine applications such as defragmentation of storage. Transparent to the Video Management System (VMS) application or the NVR(s), the shared, external IP storage must provide several capabilities for the creation and management of storage volumes. Further, all these functions must be accomplished without interruption of service to the application for non-stop operation. The required capabilities include:

� Adding or Provisioning Storage Volumes

The security practitioner or operator must be able to provision any number of storage volumes (e.g. drive E:, drive F:) of any size in the shared, external IP storage.

The addition of volumes to the installed system must happen in real time with zero down time of the system and the recording of video to the storage device must not be interrupted during the process.

� Growing or Expanding the Size of Storage Volumes The shared, external IP storage must be able to increase space utilization by growing the size of the storage volume.

Growing volumes to accommodate an increase storage demand from a set of cameras due to a number of reasons must be supported by the system in real time. This methodology would allow the user to only use the space immediately required instead of buying and allocating excess capacity in advance.

For video management systems that require a “lifetime maximum LUN size” is specified when the storage volume is created, a “thin provisioning” capability must be

www.intransa.com 7

provided to overcome this limitation, optimizing utilization by the shared, external IP storage.

For video management systems or NVRs that do not require a “lifetime maximum LUN size” at time of storage volume creation, a “grow volume” capability must be provided to optimize utilization in an ongoing manner.

� Moving Storage Volumes

Security practitioners or operators must be able to migrate or move storage volumes from one storage system to another.

� Concatenating Storage Volumes

To support large scale storage needs, the shared, external IP storage needs to support storage volumes be spread across multiple disk groups within the storage system.

� Cloning Storage Volumes For upgrades, technology refresh, backup, or disaster recovery operations, the shared, external IP storage must support storage volume cloning, or enable the creation of a full copy of the volume in real time.

� Automatic Load Balancing The Shared, external IP storage must provide automatic load balancing, supporting seamless performance delivery when:

1) The security administrator or operator is adding performance capability; 2) When a failure occurs and the storage system automatically fails over to another storage performance controller unit, and automatically load balances between remaining devices to minimize impact on the current video record/playback workload.

� Dynamic Reconfiguration

Security practitioners and operators must be able to add performance to the surveillance system without interrupting service, including recording and playback. The shared, external IP storage must dynamically accept additional performance controllers and additional storage capacity without requiring a system reboot or interrupting current recording, playback or system performance.

� Recording Latency

Any frame loss due to recording latency should be measurable on a statistical basis. The shared, external IP storage should support Zero Frame Loss operation. Additionally, the system should provide a toolset to analyze and estimate the necessary number of disk drives or enclosures to ensure a tolerable frame loss ratio as defined by the specific application environment or operator.

� Remote Boot

The shared, external IP storage system should support remote boot functionality. Remote reboot, also referred to as “iSCSI boot” or “diskless operation”, enables the recording platform (such as a DVR or NVR) to be launched using the shared, external IP storage and eliminating the need for such devices to have local disk

www.intransa.com 8

drives. This reduces cost, improves system reliability and decrease administrative burden. The shared, external IP storage should support booting several servers (DVRs or NVRs) simultaneously without any downtime for the whole system.

3.6 Integration and Certification In addition to video data recording, the shared, external IP storage should support other physical security applications, including storage of files and databases, to allow maximum utilization of the system, now and in the future. The shared, external IP storage must be tested and certified with a wide range of 3

rd party

applications and hardware in this manner to ensure proper integration. These applications should include access control, authentication, biometrics, imaging, infrastructure providers, IP megapixel cameras, IP network cameras, IT, network video recorders (NVRs), physical security infrastructure management systems (PSIMS), physical security utilities, video analytics and video management systems (VMS). The shared, external IP storage must be able to integrate with the other components of the physical security system at both hardware (Ethernet, IP, iSCSI) and software (GUI, API, SNMP) levels. Intransa shared, external IP storage is certified through the StorAlliance Technology partner labs with nearly 100 physical security, imaging, and IT applications and products (as of November 2008). 3.7 Operation and Playback The shared, external IP storage must allow fast access to recorded video data. The shared, external IP storage must be able to provide fast simultaneous retrieval and recording from several locations or video streams without compromising recording speed. The shared, external IP storage recording capability should not be affected by the retrieval process under normal conditions. The system must continue recording video streams while the security practitioner or operation is retrieving/viewing stored video.

www.intransa.com 9

3.8 Data Protection The shared, external IP storage must provide advanced data protection including fault resilient RAID (Redundant Array of Independent Disk) protection levels 0, 1, 5, 10 for video loss prevention. The storage must also be designed with OEM-grade components for increased reliability rather than less dependable PC- or consumer grade devices.

� Availability & Redundancy

The shared, external IP storage must be able to be reconfigured for support of fault resilient to highly available configurations without interrupting system availability.

� Fault Resilient Configurations

The shared, external IP storage must support fault resilient single data path, non-redundant hardware and software configurations, with hot swap disk drives, power supplies and fans, and field replaceable components.

� High Availability Configurations

The shared, external IP storage must support non-stop operational environments with multiple data paths for hardware and software configurations, with fully redundant, hot swap hardware components and automatic failover capability. The shared, external IP storage must support redundant pathways to ensure that the storage is always accessible and provide redundant storage management tools so that even with multiple component failure the video recording/playback traffic is directed through alternative routes and is able to continue.

High availability configurations must eliminate all single points of failure.

� Disk Groups

Intransa EdgeBlock fault resilient shared, external IP storage systems feature hot-swap disk drives, power supplies and fans and field replaceable data path units. Intransa EdgeBlock high reliability shared, external IP storage systems feature hot-swap disk drives, power supplies, fans, and data path units.

Intransa EdgeBlock shared, external IP storage systems feature hot-swap disk drives with global hot sparing.

www.intransa.com 10

The shared, external IP storage should support disk groups of multiple sizes and numbers of disk drives. A disk group can be made to appear to a VMS, DVR or NVR as a single drive letter or volume (e.g. Drive E:), yet actually be composed of multiple disk drives in a single enclosure or multiple enclosures.

� RAID Levels for Data Reliability

The shared, external IP storage must allow data redundancy and enable data restoration in case of disk failure by supporting RAID protection. The RAID level (0, 1, 5 & 10) must be selectable by the security practitioner or operator to meet individual application or volume requirements. The shared, external IP storage must provide automatic data recovery from individual disk failures with no downtime of the overall system. Global sparing should be provided across a single or multiple enclosures to reduce the amount of standby drives required for RAID support.

� Disk Drive Reliability

The meantime between failures (MTBF) should be as high as commercially available, typically exceeding 1 million hours of operation for OEM-grade disk drives used in the shared, external IP storage solution.

� RAID 5 Rebuild Performance

After any disk failure, the shared, external IP storage should continue to operate without interfering with the video streams or the VMS, NVR or DVR system. Video channels or recording streams should not be forced off line and frames should not be dropped/lost during a RAID5 rebuild to recover lost video.

3.9 Connectivity, Application and Protocol Support

� Physical Connections

The principal physical connection will be standard 1GbE Ethernet.

� Communications Protocols

IP running over both 1 & 10GbE network infrastructure is required. The shared, external IP storage should support SNMP and traps.

� Video Standards

The shared, external IP storage must support recording in all common standards via the surveillance and monitoring applications. These standards included 2CIF, CIF, QCIF, 4CIF and 8CIF compression and standard graphics file formats including JPEG, MPEG, MPEG-1,-2,-4 & BMP in multiple real time/time lapse formats. CCTV still, motion, full motion, time lapse, pan/tilt/zoom day/night/infrared digital and analog camera feeds with multiple FPS and resolution rates is supported. New standards such as H.264 must also be supported.

4. Environmental and Physical Requirements The shared, external IP storage will provide environmentally-friendly architectures and technologies.

4.1 Power Consumption

The security practitioner or operator should consider the consumption of power by the shared, external IP storage as a green IT technology. The system must be as electrically efficient as commercially possible. Low energy consuming IP infrastructure (in place of analog coax or high energy consuming Fibre Channel) is mandatory. High density designs should make maximum disk drive capacities available such as 750GB or 1TB disk drives in compact 2U or 3U footprints to reduce the cost and energy consumption per terabyte.

4.2 HVAC Requirements

The security practitioner or operator should also consider HVAC (heating, ventilation, and air conditioning systems) requirements of the shared, external IP storage. The system must radiate a minimum of heat (BTU), within normal IT-grade bounds for efficient storage solutions. Well designed configurations that only require additional processor/throughput capacity (such as Performance Controller Units) or storage enclosures when additional capacity is required (such as Storage Capacity Enclosures) to be added when needed are highly valued. Systems requiring larger footprints with unused capacity or performance and which therefore waste heating and cooling energy by providing more than is immediately required are to be avoided.

4.3 Floorspace / Rackspace Consumption

The security practitioner or operation should consider the amount floorspace or rackspace required by the shared, external IP storage. The system must provide high density technology and compact packaging consuming a minimum of RUs (rack units). Usage of global hot spare disk drives required for RAID configurations, and consolidation and virtualization features, to reduce overall floor and rackspace consumed are key features.

4.4 Electrical and Safety Certification Specifications

Standard equipment certification must be applicable to the shared, external IP storage. These should be at a minimum:

� FCC Class A � EN 55033 Class A � CE Mark, � ICES-003 Class A (Canada) � RoHS

www.intransa.com 15

4.5 Environmental Specifications

The shared, external IP storage solution should operate in a wide range of normal business environmental specifications.

� Temperature - 10 to 35°C (50 to 104°F) � Humidity - 10% to 90% non-condensing
