Infinidat is an Israel-based company that draws upon experience gained by key company executives, including founder and CEO Moshe Yanai, while designing and delivering EMC Symmetrix and IBM XIV systems. Its portfolio centers on its high-end, petabytescale InfiniBox storage systems. InfiniBox is used as the backend storage for Infinidat’s InfiniGuard data protection systems – the focus of this Evaluator Group Product Brief. Our separate InfiniBox Product Brief covers InfiniBox in more detail.
InfiniGuard consists of three stateless Data Deduplication Engines (DDEs) that are deployed as nodes in front of and integrated with an InfiniBox, creating a target backup-to-disk appliance that integrates with popular backup applications including Oracle Recovery Manager (RMAN) and Veeam.
InfiniBox systems use nodes of Intel-based servers. They are preinstalled in a 42U rack solution with four drive enclosures preconfigured. The device enclosure contains up to 60 top-load NLSAS disks that are 7,200 RPM for a total for 240 disks per system. The N+2 architecture used provides high availability (HA), and the InfiniGuard DDEs are deployed in a 2+1 configuration for additional availability. The controllers are interconnected with InfiniBand remote direct memory access (RDMA) networking. They connect to the attached disk storage enclosures with Serial Attached SCSI (SAS) switching. Two models of InfiniGuard solutions, the B4260N and B4212N, are available.
InfiniBox systems are currently designed for spinning disk, with performance accelerated by intelligent caching software (“Neural Cache”) and key architecture design principles. The backup and recovery performance of InfiniGuard benefits particularly from the fact that dynamic random-access memory (DRAM) is leveraged as the primary cache, and all metadata is stored on the DRAM cache. Solid-state drives (SSDs) are leveraged as the secondary cache. A proprietary trie algorithm (versus a binary tree or hashing algorithm) is used to predict and pre-cache data and to avoid collisions.
