VMware vSAN 8 U3 provides new levels of flexibility, data protection and management
vSAN 8 Update 3 is now available to all customers and partners in an initial release.
Improvements include
- Site-level fault tolerance using vSAN Express Storage Architecture (ESA)
- Disaggregated storage in VMware Cloud Foundation 5.2
- Increased scalability with vSAN File Services in vSAN ESA
- New - VMware vSAN Data Protection for better protection and recovery of virtual machines
- Improved analytics to expand device health information
- Cluster-level storage performance and RDMA troubleshooting
- Improved visibility of disaggregated clusters based on data storage systems
The release of vSAN 8.0 Update 3 has three main areas: flexible topologies, flexible data protection and improved management. With the many options available for vSAN, customers can choose the solution that best meets their specific needs, especially when used with VMware Cloud Foundation (VCF). In VCF 5.2, we added support for disaggregated storage as primary storage and increased the scale of vSAN File services by 150%.
One of the most exciting improvements in vSAN 8 U3 is the new vSAN data protection based on vSAN ESA. Data protection is a top priority for all organizations, especially when it comes to ransomware. The ability to quickly and securely recover data has become critical for customers to protect their data. vSAN Data Protection integrates with VMware Live Cyber Recovery, providing customers with additional cloud-based ransomware protection.
With vSAN, VMware aims to provide customers with advanced management capabilities that include valuable information about the performance and health of virtual machines, as well as vSAN itself. Some of the improvements in this release include additional health information at the device level, improved NVMe device tracking and alerting, and storage performance troubleshooting at the cluster level.
Enhanced vSAN ESA Clusters for VCF 5.2
Using the vSAN Express Storage Architecture (ESA) in a stretched cluster topology provides new levels of performance and efficiency. VCF 5.2, which uses vSAN 8 U3 for modern storage, now supports vSAN ESA in a stretched cluster topology. Customers can now configure workload domains that provide site-level fault tolerance. But maintaining site-level fault tolerance doesn't capture all the benefits of this new capability. VCF workloads can be stored with a much higher level of fault tolerance, while consuming less space and reducing the amount of data sent over the site-to-site link.
Disaggregated storage for VCF 5.2
In addition to increased site-level fault tolerance, vSAN 8 U3 also provides support for storage-only clusters as primary storage in VCF 5.2. VCF customers can now use vSAN disaggregated storage as the primary, centralized shared storage solution for all their VCF workloads. And since the VCF license includes entitlements to vSAN capacity, it could be the only storage customers need!
Increased scalability with vSAN File Services in vSAN ESA
vSAN ESA in vSphere 8 U3 has increased scalability and now supports up to 250 file shares per cluster. Whether you're using vSAN file services for departmental file sharing, project collaboration, or a complex microservices architecture using persistent volumes, increased scalability helps you realize these opportunities with the ability to grow.
Data protection in vSAN
With the announcement of vSAN 8 U3, we are introducing VMware vSAN Data Protection. vSAN Data Protection is the best way to protect and restore virtual machines. Powered by VMware vSAN ESA, it offers customers the ability to easily configure and use integrated high-performance snapshots in multiple ways. The snapshot portability inherent in vSAN undoubtedly increases the security and efficiency of your data center.
Intuitive management and monitoring
The benefits of vSAN Data Protection are not limited to enhanced protection and simple workflows; customers also benefit from improved management and monitoring. Snapshot information can be found throughout the user interface, whether at the cluster, virtual machine, or even protection group level. Information about snapshots, such as the number of snapshots created and the resource consumption of these snapshots, will be presented in an easy-to-understand way.
Improved device status information
In vSAN 8 U3, we've introduced new ways to collect mission-critical storage device telemetry data from your favorite server vendor so that problematic hardware conditions can be addressed in advance. Proactive Hardware Management is a new way for server vendors to integrate telemetry data from their storage devices so that vSAN can collect and detect problems and provide them to administrators in a way that is convenient for them.
Storage performance at the cluster level
Since its debut in vSAN 7 U3, the vSAN VM I/O Trip Analyzer has become a popular and useful tool for our customers looking to identify the potential source of bottlenecks in the performance of virtual machine workloads. In vSAN 8 U3, we've improved this feature by adding the ability to perform performance analysis on up to 8 virtual machines simultaneously, and to quickly run the analysis. The capabilities of vSAN I/O Trip Analyzer are a direct result of vSAN being a fully integrated component of the hypervisor, which provides unprecedented benefits not only in performance and efficiency, but also in the visibility and analytics of your workloads.
Improved RDMA troubleshooting
vSAN 8 U3 provides improved troubleshooting for vSAN using RDMA connectivity, improving tracing and monitoring of RDMA-based networks for optimal performance. Our health findings now perform a real-time check against the vSAN Hardware Compatibility List (HCL), ensuring devices are certified for use with vSAN using RDMA. It also checks the NIC driver and firmware against vSAN requirements, and if anything fails it will be presented in the vSAN cluster health assessment dashboard in a prioritized order to ensure that the most critical issues are addressed first. This enhancement will help new and existing clusters using vSAN over RDMA.
Improved visibility for storage-only clusters
VCF Operations with VCF 5.2 offers a new visualization of clusters with storage in the user interface. Storage clusters are now treated as first-class citizens in VCF Operations, where you can easily monitor resource usage and the health of storage clusters. Similar to aggregated vSAN HCI clusters, users will be able to monitor and forecast capacity needs for their environments. One of the strengths of VCF Operations is its holistic view of your entire data center, and with this latest release, you can easily see the relationships between a storage-only cluster and the vSphere clusters it provides storage resources to.
