IP SECURITY Getting to grips with storage requirements ‘With so many storage solutions on offer, it can be a confusing marketplace for end users.’ With the trend for sur veillance continuing to rise, organisations need their storage solutions to be cost effective, highly effective, available and delivered to the right places. The first step to being able to establish storage requirements is to understand how and what the video is used for, what the scale of the data output is, and how and why video will need to be retrieved. Lee Cauchie, EMEA OEM Video Surveillance BDM, Dell EMC, says: ‘Combining a storage and video strategy can be much faster and more straightforward if customers have the right vision for their business. Planning ahead of time while understanding the role of storage in video recording, storing and processing, will help drive a much more efficient, scalable, performance predictable, mistake- free solution.’ Upward trend in video driving storage End users need to be able to predict the impact that increasing video recordings will have on their storage requirements so that their storage solution will be capable of supporting their needs as they grow. Not doing so, they risk challenges and issues arising further down the line (and often when they need to access footage the most). According to Mr Cauchie, they should be specifying this as early as the first stages in the solution lifecycle. He says: ‘Video formats used are crucial and should be one of the first elements to look at when designing a storage solution. Now more than ever, videos are recorded in high resolution, causing storage ratio per minute to increase enormously. This raises the need to be able to scale in capacity faster without disrupting the business while having a solution that will suppor t the growth in bandwidth. Robustness of the solution is also an impor tant element that must be taken into account. The days of storing video on a box full of disks are long gone. The enormous amount of data created by video solutions, and the varying conditions of how this data should be stored, is the most fundamental consideration according to Dave Taylor, executive architect, Software Defined Storage Solutions, IBM Corporation: ‘I often refer to video as turning on a water hydrant, as the speed and the sheer amount of data is huge, and importantly, you have to catch every single drop! ‘Tackling the storage requirements of this data can be seen to be a huge task in itself. However, when assessing video assets, they can be divided up according to how likely it is they will need to be accessed, how frequently that might be, and what it is the asset will be used for e.g. analytics. It’s very likely there will be a huge amount of video that will never be accessed again e.g. ‘the footage from the camera monitoring the perimeter’, which differs from other organisational data because it is streamed in real-time and multiple streams are stored in parallel. The result is a phenomenal amount of data which means you can’t simply ‘grab a few disks and put them in a cabinet’. ‘With so many storage solutions on offer, from the private cloud and public cloud, to disks, tapes and hard drives, to hybrid solutions; it can be a confusing marketplace for end users. We work with the best storage vendors in the world, as when it comes to storing video, there should be no compromise, or do so at your peril.’ May 2017 | 31
