dsmISI ISP / ISP+ simplifies the integration of IBM Spectrum ProtectTM (ISP) & IBM Spectrum Protect PlusTM (ISP+) with scale-out storage environments using Isilon OneFS.
In principle, dsmISI implements dynamic multipathing, which automatically spreads reads and writes symmetrically across all available network paths and Isilon nodes, guaranteeing maximum throughput for any attached ISP and ISP+ server. dsmISI is installed on the operating system – such as Linux, Unix or Windows – as a daemon/service and communicates with Isilon clusters, creates NFS/SMB connections to all nodes and presents them to ISP and ISP+ servers as a single, very fast file system. dsmISI automatically detects whenever Isilon nodes fail or when nodes are removed from or added to a cluster. Failovers are executed transparently for ISP and ISP+. Dynamic load balancing at runtime ensures that all nodes of a cluster are being utilized equally.
With dsmISI, only one directory has to be configured on the ISP and ISP+ servers’ file device classes, while dsmISI communicates with up to 144 Isilon nodes per cluster in the background. This radically simplifies operational concepts for ISP and ISP+.
