Main points:As nodes are added to the cluster performance scales linearly and predictablyUpon a new node add the system rebalances user IO and data across all the spindles and nodes in the clusterThis eliminates hot spots and makes sure your optimizing equally all the disk in the system all the timeNo need to manually migrate data and users across volumes and RAID groups to “balance out” the array and achieve optimal performance. Isilon does it automatically!______________________________________________Example narration:If I had to choose one hallmark feature of the Isilon solution it is its ability to linearly scale performance and capacity on demand making upgrades easy and predictable without adding complexity. A three node cluster is as easy to manage as a 144 node cluster. Isilon completely eliminates the need to manually migrate data and users across volumes and RAID groups as the cluster scales.This capability goes beyond the what scale-up solutions can provide by allowing users to start with an infrastructure that fits their current requirements without overbuying performance or capacity capabilities for future use or creating additional islands of data that drive up CAPEX
Thank You for attending this presentation on Isilon’s scale-out architectures.
