General product family overview: dsmISI for Veeam – accelerated filing of Veeam repository in Dell PowerScale (OneFS Scale-out storage). In principle, dsmISI for Veeam implements dynamic multi pathing, which automatically spreads reads and writes symmetrically across all available network paths and Isilon nodes, guaranteeing maximum throughput for any attached Veeam Repository server. dsmISI for Veeam is installed on the Linux operating system and communicates with Isilon clusters, creates NFS/SMB connections to all nodes and presents them to Veeam Repository as a single, very fast XFS file system, providing support for FastClone and immutability. dsmISI for Veeam automatically detects whenever Isilon nodes fail or when nodes are removed from or added to a cluster. Failovers are executed transparently for Veeam Repository server. Dynamic load balancing at runtime ensures that all nodes of a cluster are being utilized equally.
