Design concepts and disclaimersThere are many design options for a Milestone XProtect Corporate implementation including Federations, Auxiliary Servers, and multicast considerations. PowerScale (NAS) The PowerScale scale-out network-attached storage (NAS) platform combines modular hardware with unified software to harness unstructured data. Powered by the distributed PowerScale OneFS operating system, a PowerScale cluster delivers a scalable pool of storage with a global namespace. Dell Technologies Safety & Security Lab recommendations Impact policy and priority configurationThe impact policy defines the number of parallel tasks or workers that can run at one time within OneFS. Leave the impact policy as it is, unless PowerScale directs you to change one or more policies. SmartPools job Virtual hot spare - 8 nodes or less MultiScan and AutoBalance jobs FlexProtect job Dedupe and Compression Configuring SmartConnectSmartConnect uses the existing Domain Name Service (DNS) Server and provides a layer of intelligence within the OneFS software application. Large file system, small view (SmartQuotas)Although it is possible to assign the full PowerScale cluster file system to a single XProtect Recorder, the Dell best practice is to use SmartQuotas to segment the single PowerScale file system so that each Recorder has a logical subset view of storage. Configuring SmartQuotas (recommended)The SmartQuotas feature enables you to limit the storage that is used for each XProtect Recorder. It presents a view of available storage that is based on the assigned quota to the Recorder. SmartQuotas enables each Recorder to calculate its available disk space and react appropriately. Configuring authentication and access controlWe conducted authentication and access control tests to determine the best method for shared access. Data protectionOneFS does not rely on hardware-based RAID for data protection. The PowerScale system uses the Reed-Solomon algorithm for N+M protection with Forward Error Correction (FEC).
