2 iSCSI Boot Solutions in Action Disaster Recovery and Cost Savings - Emergency Boot from the SAN If a machine fails it can be directed to boot from a snapshot or copied boot volume on the SAN. Leverages the snapshot/mirroring/cloning features Fast and efficient recovery of entire operating systems Bare system installs – Rapid Deployments Boot volumes can be quickly duplicated using snapshot or mirroring features. Shared boot volumes can be created once and assigned to many machines to boot from the same volume on the SAN. Extremely fast Eliminates time and repetitive tasks Provisioning – Meet Changing Requirements Ensures that hardware systems and storage resources are utilized to their full potential. Consolidate hardware and storage by separating them from operating systems. Fast provisioning and re-provisioning of machines - switch between boot volumes depending on the task. Blade servers - Diskless Remote Booting Uses existing Ethernet connections, enabling them to be deployed, provisioned and re-provisioned quickly. Eliminate purchasing costly HBAs Add flexibility to your blade deployments Consolidates storage Virtual machine's and Virtual storage – Gain Virtual Infrastructure Flexibility Guest operating system can now boot directly from a SAN. Tested to work on VMware & Microsoft Virtual Server. Simplified disaster recovery from virtual machine failure Fast provisioning and re-provisioning Simplifies setup and configuration
