Presented by

Tim Warden, Sr. Solutions Architect & Augie Gonzalez, Director of Product Marketing at DataCore Software

About this talk

Stretch or “metro” clusters spanning data centers in different buildings place special demands on the storage infrastructure. In this webinar you’ll learn the major considerations for attaining continuous data availability through active-active, cross-site operations, and see first-hand the storage software environment during a live demo. We’ll start with the top-level architecture for a hardware-agnostic design and work our way through the following aspects: • Isolating fault domains • Ensuring path redundancy • Mirroring between separate storage caches – distance factors • Automatic site fail-over • Resynchronization behavior before fail-back • Restoring business as usual You’ll also see how prestigious healthcare organizations have been employing these principles to prevent storage-related downtime.
