vSAN 6.7: The Future of Hyperconverged Storage
VMware has just announced the general availability of vSAN 6.7, and it’s clear that this release is packed with exciting new features and enhancements. As the leader in the HyperConverged market with a 32% market share, vSAN continues to shape the future of storage for cloud providers and enterprises alike. With over 10,000 customers at a run rate of over 600 million, it’s no surprise that vSAN is being adopted at an incredible pace.
One of the most significant enhancements in vSAN 6.7 is the new HTML5 vSphere Web Client, which offers an intuitive operational experience, consistent application experience, and holistic support experience. This new client replaces the legacy Flex client and offers a more efficient experience for users with less clicks and less time to action items. Additionally, all new features or enhancements will only be available in the new HTML5 UI, so it’s essential to upgrade to take advantage of these improvements.
One of the most exciting features in vSAN 6.7 is official support for Windows Failover Clustering using the vSAN iSCSI service. This means that lots of people who still run MSCS and use traditional clustering can now leverage vSAN’s powerful storage capabilities. With this feature, physical and virtual Guest iSCSI initiators will have transparent failover of clusters with vSAN iSCSI volumes, making it easier than ever to ensure high availability and disaster recovery.
Another significant enhancement in vSAN 6.7 is the new Adaptive ReSync feature, which ensures that resources are available for VM IO and resync IO. This feature ensures that under IO stress certain traffic types are not starved of resources and allows more bandwidth to be used when there are periods of less contention. This means that reads and writes will be optimized, resulting in better performance for both virtual machines and resync IO.
In addition to these exciting new features, vSAN 6.7 also includes several enhancements to improve data optimizations in the data path. With faster destaging, data drains more quickly from the write buffer to the capacity tier, allowing the buffer tier to be available for newer IO quicker. This results in improved performance and consistency for both VM and resync IO.
When putting a host in maintenance mode or decommissioning a host, vSAN 6.7 builds on improvements introduced in 6.6 that consolidate replicas living across multiple hosts while maintaining FTT compliance. This feature consolidates replicas more efficiently and reduces the time and effort required to put a host into maintenance mode.
Finally, vSAN 6.7 includes several smaller enhancements that improve the overall experience of using the platform. For example, the VM swap object is now thin by default, which results in more efficient storage and less temporary space usage. Additionally, the new enhanced health checks add a new dimension to vSAN troubleshooting, allowing users to quickly identify and resolve issues.
In conclusion, vSAN 6.7 is an exciting release that offers several significant enhancements over previous versions. With its intuitive operational experience, consistent application experience, and holistic support experience, vSAN continues to set the standard for HyperConverged storage. Additionally, with official support for Windows Failover Clustering and enhanced data optimizations, vSAN 6.7 is an essential upgrade for anyone looking to improve their storage capabilities.
