Why Is 3-Way Synchronous Mirroring Better Than 2-Way? A new PDF released by Starwind software discuss the possibility to use 3 servers to achieve better availability than in a configuration with 2 servers. If you follow my website and you’re regular reader, you might already noticed that the Starwind has released version 6.0 of their popular iSCSI SAN Software.
If you’re VCP or vExpert you can ask for an NFR license and use it for demos or home-labing. In fact, all those people can ask for a license - vExperts, VMware Certified Instructors (VCI), Microsoft Most Valuable Professionals (MVP), Microsoft Certified Trainers (MCT), Citrix Technology Professionals (CTP), and Citrix Certified Instructors (CCI).
A freshly released white paper from Starwind Software describes the difference between 3-and 2-way synchronous mirroring – capabilities that are both available in the StarWind iSCSI SAN & NAS solution. The document outlines the advantages of the 3-node high availability storage cluster that provides cost efficiency, increased reliability, and higher performance compared to 2-node HA.
If you’re new to virtualization, the Starwind iSCSI SAN 6.0 software creates shared storage which is presented to your ESXi hosts. This shared storage enables to use functionnalities like High Availability (HA) – automatic failover and restart of VMs – in case one of your ESXi hosts present in the HA cluster, fails.
