    vSAN is compatible with any edition of vSphere and it is available in multiple packages to accommodate a variety of specific needs and use cases. This guide explains the vSAN licensing editions, discusses some
    vSAN configuration options at a high level, and provides a number of examples to illustrate potential licensing scenarios.

License Editions

vSAN license editions include Standard, Advanced, Enterprise, and Remote Office/Branch Office (ROBO) Standard, Advanced, and Enterprise. The following table shows the features included with each license edition.
Contributing factors

vSAN 6.7 comes with HTML5 User Interface which is completely redesigned to deliver a modern management experience. Standard licensing includes support for hybrid configurations—magnetic disks for capacity, flash devices for caching—and all-flash configurations. This change from the vSAN 6.2 licensing model enables the use of all-flash hardware while minimizing licensing costs. It is important to note that Standard licensing does not include support for deduplication, compression, and erasure coding. Advanced licensing is required for these space efficiency features.
The Enterprise license builds on the features included with vSAN Standard and Advanced by adding support for vSAN stretched cluster configurations and data-at-rest encryption. vSAN for ROBO Advanced was introduced in vSAN 6.5 release and is only available in vSAN 6.5 or later versions. vSAN for ROBO Enterprise was introduced in vSAN 6.6.1. In vSAN 6.7 release, vRealize Operations within vCenter feature was made available to Advanced and Enterprise editions of vSAN.

vSAN Standard, Advanced, and Enterprise editions are licensed per-CPU (socket). They are available as standalone licenses and are not included with VMware vSphere® or VMware vSphere with Operations
Management™. Any type of workload—server and desktop—can be run on a vSAN cluster with these licensing editions.
A vSphere host that is not contributing local storage to a vSAN datastore can be a member of the vSAN cluster and utilize the vSAN datastore. Even though a host is not contributing storage, the host must be licensed for vSAN.
vSAN data-at-rest encryption requires an external Key Management Server (referred as KMS), which provides the primary encryption key. This key is used to encrypt other keys in the cluster. While VMware does not provide a KMS solution, vSAN encryption is certified to work with enterprise grade key management servers. Please note, KMS vendors may have an additional licensing requirement. Different KMS vendors offer different license options, please check with the KMS vendor for further details. For a list of certified KMS vendors, refer to the VMware compatibility guide.

Virtual Desktop Infrastructure

vSAN for Desktop licensing is available for customers using vSAN exclusively for virtual desktop infrastructure (VDI). This includes third-party VDI solutions in addition to VMware Horizon®. While this license option limits the use of vSAN to VDI workloads only, vSAN for Desktop provides unique pricing and packaging options to help further reduce the cost of VDI while enabling the benefits and performance of a distributed storage platform. vSAN for Desktop is available in Standard, Advanced, and Enterprise editions. It is priced per-concurrent user (CCU) in a virtual desktop environment and sold in packs of 10 and 100 licenses.
In addition to being available standalone, vSAN for Desktop Advanced licenses are also included with VMware Horizon Advanced and Enterprise editions.

Troubleshooting VSAN Performance

Executive Summary

An infrastructure that delivers sufficient performance for applications is a table stake for data center administrators. The lack of sufficient and predictable performance can not only impact the VMs that run in an environment, but the consumers who use those applications. Determining the root cause of performance issues in any environment can be a challenge, but with environments running dozens, if not hundreds of virtual workloads, pinpointing the exact causes, and understanding the options for mitigation can be difficult for even the experienced administrator.

VMware vSAN is a distributed storage solution that is fully integrated into VMware vSphere. By aggregating local storage devices in each host across a cluster, vSAN is a unique, and innovative approach to providing cluster-wide, shared storage and data services to all virtual workloads running in a cluster. While it eliminates many of the design, operation and performance challenges associated with
three-tier architectures using storage arrays, it introduces additional considerations in diagnosing and mitigating performance issues that may be storage related.

This document will help the reader better understand how to identify, quantify, and remediate performance issues of real workloads running in a vSAN powered environment running all-flash. It is not a step-by-step guide for all possible situations, but rather, a framework of considerations in how to address problems that are perceived to be performance related. The example provided in Appendix C will illustrate how this framework can be used. The information provided assumes an understanding of virtualization, vSAN, infrastructures, and applications

Diagnostics and Remediation Overview

vSAN environments may experience performance challenges in a variety of circumstances. This includes:

  • Proof of Concept (PoC) phase using synthetic testing, or performance benchmarking
  • Initial migration of production workloads to vSAN
  • Normal day-to-day operation of production workloads
  • Evolving demands of production workloads

The primary area of focus of this document is related to production workloads in a vSAN environment. Many of the same mitigation steps can be used to evaluate performance challenges when using synthetic I/O testing during an initial PoC. A vSAN Performance Evaluation Checklist offers a collection of guidance and practices for PoCs that will be helpful for customers in that phase of the process.
Accurately diagnosing performance issues of a production environment requires care, persistence and correctly understanding the factors that can commonly contribute to performance challenges.

Contributing Factors

Several factors influence the expected outcome of system performance in a customer’s environment, and the behavior of workloads for that specific organization. Most fall in one of the five categories, but are not mutually exclusive. These factors contribute to the performance vSAN is able to provide, as well as the performance perceived by users and administrators. When reviewing previous performance issues in any
architecture where a root cause was determined, you’ll find that the reason can often trace back to one or more of these five categories.

Contributing factors

Understanding the contributing factors to a performance issue is critical to knowing what information needs to be collected to begin the process of diagnosis and mitigation.

Process of Diagnosis and Mitigation

A process for diagnosis and mitigation helps work through the problem, and address it in a clear and systematic way. Without this level of discipline, further speculation and potential remedies to the issue
will be scattered, and ineffective in addressing the actual issue. This process can be broken down into five steps:

    1. Identify and quantify. This step helps to clearly define the issue. Clarifying questions can help properly qualify the problem statement, which will allow for a more targeted approach to addressing. This process helps sort out real versus perceived issues, and focuses on the end result and supporting symptoms, without implying the cause of the issue.

    2. Discovery/Review – Environment. This step takes a review of the current configuration. This will help eliminate previously unnoticed basic configuration or topology issues that might be plaguing the environment.

    3. Discovery/Review – Workload. This step will help the reader review the applications and workflows. This will help a virtualization administrator better understand what the application is attempting to perform, and why.

    4. Performance Metrics – Insight. This step will review some of the key performance metrics to view, and how to interpret some of the findings the reader may see when observing their workloads. It clarifies what the performance metrics means, and how they relate to each other..

    5. Mitigation – Options in potential software and hardware changes. This step will help the reader step through the potential actions for mitigation.

A performance issue can be defined in a myriad of ways. For storage performance issues with production workloads, the primary indicator of storage performance challenges is I/O latency as seen by the guest VM running the application(s). Latency, and other critical metrics are discussed in greater detail in steps 4 and 5 of this diagnosis workflow. With guest VM latency being the leading symptom of insufficient performance of a production workload, and an understanding of the influencing factors that contribute to storage performance (shown in Figure 1.), the troubleshooting workflow for vSAN could be visualized similar to what is found in Figure 2 below.

A visual representation of a performance troubleshooting workflow

This document follows the process of diagnosis and mitigation described in Figure 2, and will elaborate on each step in an appropriate level of detail. Recommendations are provided on specific metrics to monitor (In Step 4, and Appendix A), and what they mean to the applications and the environment.
Additionally, the reader will find a summary of useful tools (found In Appendix B) should there be a desire to explore the details at a deeper level. Troubleshooting performance issues can be difficult even under the best of circumstances. This is made worse by skipping valuable steps in gathering information about the issue to really understand and define the problem. Therefore, the information provided here places emphasis on understanding the environment and workloads over associating each potential performance problem with a single fix.

This document does not cover the details of how to evaluate vSAN for a PoC environment, nor does it provide detail on how to run synthetic I/O based performance benchmarks. The information provided here closely aligns with the recommendations found in the vSAN Performance Evaluation Checklist, which is a great resource to level-set an environment for performance evaluation.

VSAN Easy Install

First Published On: 04-11-2017
Last Updated On: 05-02-2018

An Introduction to Easy Install

Deploying VMware vSAN is not a difficult task. The vSAN Cluster Wizard is one of the workflows included in configuring a vSAN as a part of a vSphere Cluster. To use this wizard, some tasks had to accomplished beforehand as prerequisites of vSAN. These tasks were accomplished by vCenter:

    1. A Datacenter had to be created
    2. A Cluster had to be created
    3. Hosts had to be added to the cluster
    4. A VMkernel port had to be added to each host for vSAN communications
    5. A VMkernel port had to be added to each host for vMotion communications
    6. vSAN could then be enabled.To accomplish these tasks, vCenter had to already be installed somewhere.
In environments where vCenter (Windows or VCSA) already existed, it was not difficult. In “greenfield” deployments it was a bit more challenging. There were a couple methods for “bootstrapping” a VCSA to accomplish this task of getting vCenter running on top of the vSAN datastore it was managing.

Pre-Easy Install

Before Easy Install, there were a couple mechanisms to bootstrap the VCSA onto a vSAN installation.

Method 1 – Using a Temporary Datastore

Virtualization administrators familiar with Storage vMotion are aware that a virtual machine, or VCSA appliance in this case, can be Storage vMotioned to the vsanDatastore after being installed on a traditional VMFS volume. This process is traditionally called using a “Transfer datastore” or a “swing datastore.” The steps to use this method include:
  • Create a local VMFS datastore on the first host
  • Deploy the VCSA to the temporary datastore
  • Create a vSAN Cluster, including the first host
  • Add two or more additional ESXi hosts to the vSAN Cluster
  • Ensure vSAN networking is in place for all hosts and they are communicating properly
  • Storage vMotion the VCSA to the vSAN Datastore
  • Destroy the local VMFS datastore on the first host, ensuring no partitions remain on the device (vSAN doesn’t work with VMFS partitions)
  • Add a disk group on the first host
This process isn’t complicated, but is a bit transient. The transfer or swing datastore only serves the purpose of allowing the VCSA to be configured and then ultimately moved to the vSAN datastore. William Lam posted this method on in 2013.

Method 2 – Manually Creating the vSAN Datastore

This method is a bit more complicated. An alternative to using a temporary datastore, is manually setting up a vSAN datastore on the first host as a target for the deployment of the VCSA. The process is as follows:
  • Install ESXi 6.x on physical hosts.
  • Because the vSAN default policy requires includes a Failure Tolerance Method of Mirroring and a Number of Failures to Tolerate of 1, the only way to deploy to a vSAN cluster with a single node, is to modify the default Storage Policy to allow for forced provisioning. The following command will need to be run on the first host: For virtual disks: esxcli vsan policy setdefault –c vdisk –p “((\”hostFailuresToTolerate\” i1) (\”forceProvisioning\” i1))” For the VM namespace: esxcli vsan policy setdefault –c vmnamespace –p “((\”hostFailuresToTolerate\” i1)(\”forceProvisioning\” i1))”
  • Now a vSAN cluster must be created. This is done from the ESXi console using the command: esxcli vsan cluster new
  • At least a single disk group must be created using the following command: esxcli vsan storage add -s SSD-DISK-ID -d HDD-DISK-ID Device ID’s can be listed using: esxcli storage core device list A disk group can be created with multiple capacity devices like this: esxcli vsan storage add –s SSD-DISK-ID –d HDD-DISK1-ID –d HDD-DISK2-ID –d HDD-DISK3-ID
  • The VCSA installer can be used to deploy the VCSA to the first host with the manually created vsanDatastore.
  • Once the VCSA has been deployed, a Datacenter has to be created, a Cluster (with vSAN enabled) and the first host added.
  • Additional hosts can then be added, as well as vSAN networking
As can be easily seen, the manual method it a bit more complex. William Lam posted this method on in 2013.

Easy Install using the VCSA Installer for vSAN 6.6

Easy Install takes the effort out of installing the VCSA on a standalone host and enabling vSAN for a larger deployment.
With the introduction of vSAN 6.6, installation of the VCSA to a brand new, “greenfield” vSAN cluster is very simple using the Easy Install method.

The Easy Install method is only available when connecting the VCSA installer to an ESXi host that has vSAN 6.6 preinstalled. Hosts that have previous builds of ESXi will not be presented the option of creating a vSAN datastore.

When presented with the “Select datastore” wizard, “Install on a new vSAN cluster containing the target host” is an alternate option to installing on an existing datastore.

What’s New in vSAN 6.7 Update 1

Jase McCarty posted October 16, 2018

VSAN Capacity Overview

VMware vSAN
is the market leader in HCI. One of the many driving forces that has helped solidify this position, is the rapid and continuous pace of innovation. VMware has always given customers the power of choice, and this continues into the hybrid cloud era. VMware’s digital foundation gives customers the ability, and flexibility to build true hybrid cloud environments to best suite their use cases. VMware offers a full stack SDDC, and HCI is the starting point for those transitioning to a software-defined infrastructure.

VMware HCI, the Best Building Block for a Digital Foundation

Data centers powered by VMware vSAN offer scalability, flexibility, and manageability to meet nearly any demand, and is the cornerstone for customers looking to build private clouds and extend their multi-cloud capabilities.
VMware vSAN is the only storage software natively integrated with the market-leading hypervisor, vSphere. This unique integration delivers optimal resource utilization for the most critical of applications.

VMware vSAN provides industry-leading deployment flexibility with the largest HCI ecosystem. Over 15,000 private clouds, running on over 500+ ReadyNodes™, jointly certified servers, VxRail – a jointly engineered turnkey appliance, as well as two of the largest public cloud providers, Amazon and IBM. Run HCI on the hardware you prefer.

VMware uniquely provides centralized management of all your HCI deployments from edge to core to cloud from the same tools you use today, vCenter and vRealize . These can optimize your operational efficiency with a single toolset across the hybrid cloud, without having to learn any new skills.

All of these features are available today. Not tomorrow, not next quarter, not next year, today. Only VMware can deliver a true hybrid cloud to your data center now.

vSAN 6.7 U1 Makes it Easy to Adopt HCI

VMware vSAN 6.7 U1 makes it even easier to adopt HCI and build a Digital Foundation. Key areas where vSAN 6.7 U1 provides additional benefits include the simplification of day one and two operations, lowering the total cost of ownership with more efficient infrastructure, and even more rapid support and resolution with ReadyCare.

First, we are simplifying operations day one and two operations by streamlining the deployment process, improving lifecycle management, reducing disruptions during maintenance operations, and improving capacity reporting. These updates help administrators more quickly and easily deploy and extend infrastructure while minimizing disruptions while keeping the environment up to date.

Simplified Operations – Cluster Quickstart

Speed to market and configuration consistency are paramount to reduce risk, maintain uniformity, and achieve better stability and efficiency. A new “Quickstart” guided cluster creation wizard gives administrators a streamlined mechanism for deploying vSAN, and non-vSAN, clusters.

An easy to use, step-by-step configuration wizard makes creating a production-ready vSAN cluster effortless. Cluster Quickstart handles initial deployment, as well as the process of expanding the cluster as needs change.

VSAN Capacity Overview

The Cluster Quickstart wizard workflow includes these tasks and more to ease the deployment process:

  • Cluster services including vSphere HA, vSphere DRS, and vSAN
  • Adding hosts – Add multiple hosts simultaneously
  • vSAN deployment type
  • Network configuration including vSphere Distributed Switching
  • Disk Group configuration
  • Data Services like Deduplication & Compression / Encryption

The Cluster Quickstart wizard works great for configuring vSAN clusters added to an existing vCenter 6.7 U1 deployment, as well as a great next step after using vSAN Easy Install to bootstrap a new vCenter onto the first host in a new vSAN cluster.

The Cluster Quickstart wizard can be seen in action on StorageHub.

Driver & Firmware Updates using Update Manager

Updated in vSAN 6.7 U1, all ESXi, driver, and firmware update functions previously handled by the Configuration Assist workflow have been moved to vSphere Update Manager.

VSAN Capacity Overview

Specific OEM builds can be supported in vSphere Update Manager for 6.7 U1 because it will support the use of OEM vendor ISOs. For those needing to update environments that do not have Internet connectivity, new workflows provide guidance for adding updates to the network isolated environment.

Decommissioning and Maintenance Mode Safeguards in vSAN 6.7 U1

Since each vSAN host in a cluster contributes to the cluster storage capacity, entering a host into maintenance mode takes on an additional set of tasks when compared to a traditional architecture.
vSAN 6.7 U1 has improved the safeguards when performing maintenance and decommissioning activities on vSAN hosts. vSAN will now perform a full simulation of data movement to determine if the process of entering maintenance mode will succeed or fail before it even starts. This will prevent unnecessary data movement and provide a result more quickly to the administrator.

VSAN Capacity Overview

New warnings have been added to entering maintenance mode activities to ensure that there are no other hosts already in maintenance mode or resync activity current performing.

For cases where an administrator needs to adjust the time vSAN waits before it begins to rebuild data to reestablish compliance with storage policies, a new “object repair timer delay” setting is now in the UI.

VSAN Capacity Overview

All of these improvements are added to enhance the overall experience and predictability of host decommissioning activities like entering a host into maintenance mode.

More vRealize Operations Intelligence

In vSAN 6.7, “vRealize Operations within vCenter” provided an easy way for customers to see basic vRealize intelligence with vCenter.
New in vSAN 6.7 U1, vRealize Operations dashboards have the ability to differentiate between normal and stretched vSAN clusters, displaying appropriate intelligence for each.
VSAN Capacity Overview

An incredible number of metrics are exposed to assist with monitoring and issue remediation. vRealize Operations makes it easier to correlate data from multiple sources to speed troubleshooting and root cause analysis.

Improved Capacity Reporting

vSAN 6.7 U1 enhances capacity reporting in a few different ways. Having a better understanding of past, present, and future capacity utilization is a top-of-mind concern for administrators.
In vSAN 6.7, Administrators can easily:

  • Estimate the amount of usable capacity based on a desired storage policyVSAN Capacity Overview
  • Determine the capacity required if deduplication & compression were disabledVSAN Capacity Overview
  • See the amount of capacity used historically in vSAN 6.7 U1, including changes in deduplication & compression ratios over time.VSAN Capacity Overview

Efficient Infrastructure

Next, vSAN is an even more efficient infrastructure choice. More efficient infrastructure helps in lowering the total cost of ownership. Space reclamation, enhanced networking support for some architectures, as well as better sizing tools lead to even more efficiencies with vSAN.


Popular workloads can use less storage through the process of automatic space reclamation. The addition of TRIM/UNMAP support can automatically reclaim capacity that is no longer used, reduces the capacity needed for popular workloads without administrator interaction.

Trim Unmap

TRIM/UNMAP will be supported in a variety of Guest Operating Systems, virtual hardware configurations, and virtual machine configurations.

Mixed MTU Support for 2 Node and Stretched Clusters

In a stretched cluster environment, the ability to isolate witness traffic using dedicated uplinks was a powerful enhancement made to vSAN 6.7. vSAN 6.7 U1 introduces additional levels of flexibility to this feature with the support of mixed MTU sizes configured for witness traffic, and the Inter-site link used for vSAN data traffic.


This allows for a user to configure vSAN to use perhaps larger frame sizes on the vSAN data network while keeping the witness uplinks going to the more affordable witness site to a more common standard MTU size. This enhancement will give additional flexibility in accommodating a wider variety of customer topology conditions and reduce potential network issues.

Updated Sizing Tools

We’re also introducing new capabilities that simplify planning to help customers size the most efficient deployment for their environment.



Updates to the HCI Assessment and vSAN Sizer tools work even better together to provide a more streamlined and flexible sizing and infrastructure selection process to ensure the most efficient configuration for new deployments.

Rapid Support Resolution

Faster resolution, quicker diagnosis, and simplified self-help make vSAN Supportability even better. vSAN ReadyCare has simplified the support process by reducing requirements of customers, and speeding time to resolution through faster insight and integrated self-help in vSAN.

Improved Health Check Guidance

The health check feature of vSAN continues to play a prominent role in its ability to ensure that an environment meets hardware and software configuration requirements.vSAN 6.7 U1 extends this feature even more, with a more robust way of handling multiple approved firmware levels for storage controllers.
Health Check

A new Unicast network performance health check and test ensures that proper continuity is achieved between vSAN hosts and will report network bandwidth results for the tests.vSAN 6.7 U1 also introduces functionality that is now accessible in the UI. Health checks can be silenced granularity, directly in the UI, as well as being able to purge inaccessible swap objects that are no longer needed.These improvements improve the effectiveness of vSAN’s ability to not only recognize issues but remediate them more quickly.

Enhanced Support Diagnostics

vSAN 6.6.1 introduced “vSAN Support Insight,” VMware’s method of automatically collecting vital infrastructure telemetry data about an environment for the VMware technical support engineers in our global support services group.
vSAN 6.7 U1 continues with these improvements, introducing fine-grained, deep level performance graphs for the explicit purpose of issue resolution. GSS engineers will have new tools for capturing critical network diagnostic data. These advances help reduce the need to request log support bundles from the hosts, and when they are absolutely necessary, will contain even more critical data for better root cause analysis.

Support Diag

Native health checks, more self-help tools, better reactive support with vSAN Support Insight, and participation in the VMware Customer Experience Improvement program, provide for an overall enhanced support experience. VMware can rapidly understand a customer’s environment, perform root cause analysis to identify the cause of the problem, and deliver proactive support based on trends and analytics.


VMware vSAN continues to innovate at a rapid pace, making it even easier to adopt HCI and build a Digital Foundation. Simplified operations, a lower cost of ownership, and even more rapid support and resolution are just a few of the key areas that help make VMware HCI with vSAN the industry-leading HCI provider. Whether on-premises or in the cloud, only VMware can deliver a true hybrid cloud to your data center now.
