The vSAN API and vSphere PowerCLI have been updated in this release. It is now possible to automate the configuration and management of cluster settings, disk groups, fault domains, and stretched clusters. Activities such as maintenance mode and cluster shutdown can also be scripted. This video demonstrates some of the capabilities of of the vSAN API and PowerCLI: Creating a Cluster and Configuring vSAN PowerCLI can be used to monitor the health of a vSAN cluster. Health issue remediation and re-sync activities can be automated with this latest release.
20-50% Additional TCO Savings
Now that flash devices have become the preferred choice for storage, it makes sense to adjust the vSAN licensing model to account for this change in the industry. All vSAN 6.5 licenses include support for both hybrid and all-flash configurations. Please note, however, that deduplication, compression, and erasure coding still require vSAN Advanced or Enterprise licenses. Adding support for the use of all-flash configurations with all licensing editions provides organizations more deployment options and the ability to take advantage of increased performance while minimizing licensing costs.
vsan_2_nodevSAN supports the use of network crossover cables in 2-node configurations. This is especially beneficial in use cases such as remote office and branch office (ROBO) deployments where it can be cost prohibitive to procure, deploy, and manage 10GbE networking equipment at each location. This configuration also reduces complexity and improves reliability.
While we are on the subject of ROBO deployments, it is also important to mention a related vSAN licensing change. vSAN for ROBO licensing previously did not support the use of all-flash vSAN cluster configurations and the corresponding space efficiency features. A new license has been added with the release of vSAN 6.5 and it is called vSAN for ROBO Advanced. This new license includes support for using deduplication, compression, and erasure coding. Using these features lowers the cost-per-usable-GB of flash storage, which further reduces TCO. Organizations get the best of both worlds: The extreme performance of flash at a cost that is on par with or lower than similar hybrid solutions.
vSAN 6.5 extends workload support to physical servers and clustered applications with the introduction of an iSCSI target service. vSAN continues its track record of being radically simple by making it easy to access vSAN storage using the iSCSI protocol with just a few vSphere Web Client mouse clicks. iSCSI targets on vSAN are managed the same as other objects with Storage Policy Based Management (SPBM). vSAN functionality such as deduplication, compression, mirroring, and erasure coding can be utilized with the iSCSI target service. CHAP and Mutual CHAP authentication is supported.
Utilizing vSAN for physical server workloads and clustered applications can reduce or eliminate the dependency on legacy storage solutions while providing the benefits of vSAN such as simplicity, centralized management and monitoring, and high availability.
