Petabyte-Scale (PB) Disaggregated Storage for vSphere

vSAN Max provides petabyte-scale disaggregated storage for vSphere environments. It enables the provisioning of a vSAN cluster that serves as shared storage for vSphere clusters. With vSAN Max, companies no longer have to provide and maintain separate storage arrays, controllers, and traditional architectures. This approach offers scalability and cost efficiency, combining the convenience of a three-tier architecture with the simplicity of vSAN.

Scaling Storage with vSAN Max

The introduction of vSAN Max brings scale-out storage capabilities, a feature not available in many dedicated storage solutions. Users can now scale out storage one server at a time, improving capacity and performance in a manageable and budget-friendly way. This approach helps reduce storage costs as storage needs change, making it a cost-effective solution.

Unified Management Interface

One of the key features of vSAN Max is its unified single interface for management. It seamlessly integrates with existing vSAN clusters, allowing users to manage their storage with the same ease and familiarity as other vSAN components. This feature simplifies the management of storage resources, ensuring a consistent user experience.

vSAN Max: Addressing Diverse Use Cases

While the traditional HCI model of vSAN has been successful, vSAN Max extends this success by addressing specific use cases. It is particularly well-suited for providing centralized shared storage for entire environments. Customers heavily invested in blades can take advantage of vSAN Max, which offers an optimal solution for constructing vSphere clusters in a more strategic and cost-effective manner. With its flexibility and performance, vSAN Max caters to a wide range of use cases.

Architecture of vSAN Max

At its core, vSAN Max comprises a cluster of vSAN hosts dedicated to providing shared storage to other clusters. It is different from the traditional vSAN HCI model as it focuses exclusively on storage, without hosting any VM instances. This specialization allows vSAN Max to serve as primary storage for vSphere clusters or add storage for vSphere and other vSAN clusters. The flexibility it offers enables easy integration between traditional and disaggregated HCI environments.

Leveraging the vSAN Express Storage Architecture

vSAN Max is built upon the vSAN Express Storage Architecture (ESA) foundation. This architecture brings new levels of performance and efficiency to storage solutions. With vSAN Max, customers can flexibly consume storage resources and benefit from improved storage performance and efficiency.

Configuring vSAN Max Clusters

The process of configuring a vSAN Max cluster is streamlined and intuitive. Administrators can choose between a traditional aggregated vSAN HCI cluster, a vSAN Max cluster, or a vSphere cluster using remote vSAN-powered storage. Furthermore, vSAN Max can be configured as either a single-site cluster or a stretched cluster to provide resilient remote storage across two sites. The provisioning of vSAN Max is made simple through well-designed configuration processes.

Auto Policy Management in vSAN Max

The Auto Policy Management feature in vSAN Max simplifies storage management by automatically determining the optimal default storage policy based on cluster size.

This feature allows for the provisioning of virtual machines, ensuring they are configured for optimal resilience without requiring manual intervention.

Integrating vSAN Max with Traditional vSphere Clusters

Integrating vSAN Max storage resources with traditional vSphere clusters is straightforward. The remote datastore can be easily mounted at the cluster level, making the storage immediately ready for use. This integration exemplifies the flexibility and ease of operation that vSAN Max offers.

Ongoing Operations and Management

Ongoing operations of a vSAN Max cluster are as easy as the initial setup. Administrators can rely on vCenter Server, which provides a comprehensive dashboard displaying critical information, performance metrics, and capacity details. The management interface simplifies monitoring and operations, ensuring smooth day-to-day management of the cluster.

Enhanced Adaptive Write Path in Disaggregated Environments

vSAN 8 Update 2 enhances the Express Storage Architecture (ESA) with an improved Adaptive Write Path. This enhancement significantly boosts throughput and reduces latency in real-time without requiring administrator intervention. With increased performance, vSAN Max demonstrates its capabilities in disaggregated environments.

Increased VM Density and Efficiency

vSAN 8 Update 2 further improves the efficiency of vSAN ESA in both data storage and processing. The update increases the number of supported VMs per host from 200 to 500, allowing for high-density cluster designs. Customers can run more VMs over fewer hosts, especially in environments with the latest hardware. This update enables businesses to enhance their virtualization platform and increase resource utilization.

New Ready Node Profile and Support for Lower Endurance Devices

vSAN 8 Update 2 introduces the AF-0 Ready Node Profile, designed for smaller customer requirements and data centers. This profile, available with AMD or Intel CPUs, offers a cost-effective option for environments with lower-endurance write-intensive storage disks. It provides flexibility and efficient storage solutions that meet various workload demands.

Simplified Day-to-Day Operations

The update release simplifies daily operations for administrators. The Auto Policy Management feature, enhanced in this update, automatically adjusts the optimized default storage policy upon the addition or removal of a host from a cluster for maximum protection. This intelligent default policy administration reduces management overhead and ensures optimal resilience across the cluster.

Enhanced Reporting and Data Processing

vSAN 8 Update 2 improves the reporting of capacity overheads for objects residing in the data store. The new ESA object overhead category in the usage breakdown section provides administrators with a clearer understanding of capacity consumption overhead in their storage system instance. The enhanced reporting and data processing capabilities help administrators analyze and optimize storage usage.

Streamlined Management with vSAN ESA Prescriptive Disk Claim Capability

The vSAN ESA Prescriptive Disk Claim Capability allows administrators to define a standardized disk configuration outcome for hosts in a cluster. This simplifies the management of storage devices, ensuring consistent configurations across the environment. In case a host cannot maintain the prescribed configuration, vSAN’s health system detects and alerts administrators through the Skyline Health for vSAN feature.

Enhanced Security and Health Monitoring

vSAN 8 Update 2 supports KMS servers with a key expiration attribute, enhancing the security capabilities and hardening measures of infrastructure.

The Skyline Health for vSAN feature alerts administrators of impending key expirations, enabling proactive re-key operations and automating remediation processes. These improved security measures help organizations meet compliance requirements and mitigate potential risks.

Improved Performance Analysis and Analytics Tools

vSAN 8 Update 2 enhances the Top Contributors view, allowing administrators to identify performance hotspots over customizable periods. The vSAN IO Trip Analyzer now includes analysis capabilities for workloads running in a vSAN stretch cluster, helping pinpoint the primary sources of latency. These tools reduce resolution times for issues and enable administrators to optimize performance effectively.

Simplified Configuration of a vSAN Stretched Cluster and Two Node Topologies

Configuring stretch clusters and two-node topologies is now easier with vSAN 8 Update 2. Administrators can tag vSAN witness network traffic directly through the VMkernel configuration settings, simplifying networking. The vSAN express storage architecture now offers expanded options for witness host appliance sizes, including a medium-sized option. These enhancements support the design and implementation of vSAN stretch clusters with greater flexibility.

Download vSAN Max or License?

VMware Cloud Foundation and the vSAN advanced add-on for VMware vSphere Foundation are available with licensing based on a Per Terabyte (TiB) metric. This licensing approach allows customers to license the amount of storage capacity required for their specific environments.

Licensing guidelines require that you license vSAN for all raw storage capacity utilized by vSAN. It is essential to consider these guidelines.
