This solution demonstrates how to use Dell EMC storage platforms to provide the storage resources for a multitier XProtect safety and security video implementation.
Although not Milestone best practice, a single tier solution may be implemented.
Planning and designing the storage infrastructure is a critical step due to the XProtect requirement for both Live DB and Archive DB tiers for safety and security video data. Each network-attached (NAS) storage tier must be able to accommodate large amounts of large block sequential data, even during times when storage paths are crippled (for example, during disk rebuilds, network issues, and maintenance). Otherwise, loss of video will occur.
To provide predictable performance for each tier of the XProtect video storage infrastructure, the storage must be able to handle sustained, high-bandwidth video feeds from servers without dropping video frames or introducing high response times for users reviewing the video. Designing for this workload includes deploying Live DB storage (Tier-1 storage) on Dell EMC FC or iSCSI arrays or, for smaller environments, DAS (internal server storage). The Live DB read performance is also a design consideration for moving the video data from the Live DB to the Archive DB (Tier-2 storage).
