NOTE: This video is roughly 30 minutes in length so it would be worth blocking out some time to watch it!
We would like to remind you that the End of General Support (EOGS) for vSphere 5.5 and vSAN 5.5 is September 19, 2018.
To maintain your full level of Support and Subscription Services, VMware recommends upgrading to vSphere 6.5 or 6.7. Note that by upgrading to vSphere 6.5 or 6.7 you not only get all the latest capabilities of vSphere but also the latest vSAN release and capabilities.
vCloud Suite 5 and vSphere with Operations Management (vSOM) customers running vSphere 5.5 are also recommended to upgrade to vSphere 6.5 or 6.7. For more information on the benefits of upgrading and how to upgrade, visit the VMware vSphere Upgrade Center.
For detailed technical guidance, visit vSphere Central and the vSphere 6.5 Topology and Upgrade Planning Tool. VMware has extended general support for vSphere 6.5 to a full five years from date of release, which will end on November 15, 2021. This same date applies to vSphere 6.7 end of general support as well.
If you require assistance upgrading to a newer version of vSphere, VMware’s vSphere Upgrade Service is available. This service delivers a comprehensive guide to upgrading your virtual infrastructure including recommendations for planning and testing the upgrade, the actual upgrade itself, validation guidance, and rollback procedures. For more information, contact your VMware account team, VMware Partner, or visit VMware Professional Services.
If you are unable to upgrade from vSphere 5.5 before EOGS and are active on Support and Subscription Services, you may purchase Extended Support in one-year increments for up to two years beyond the EOGS date. Visit VMware Extended Support for more information.
Technical Guidance for vSphere 5.5 is available until September 19, 2020 primarily through the self-help portal. During the Technical Guidance phase, VMware will not offer new hardware support, server/client/guest OS updates, new security patches or bug fixes unless otherwise noted. For more information, visit VMware Lifecycle Support Phases.
Listed below are a number of additional actions which need to be taken, depending on your individual scenario:
vSphere with Operations Management (vSOM)
This bundle of vSphere and vRealize Operations allows you to upgrade the versions of individual components independent of each other. If you are using vSphere 5.5 as part of vSOM, you will need to upgrade your vSphere with Operations Management 5.5 license key, to be able to upgrade the vSphere component. You can reference the VMware Lifecycle Product Matrix to check for the EOGS date for the version of vRealize Operations you are using and the VMware Product Interoperability Matrices for the product version compatibility.
vCloud Suite 5
This bundle of vSphere and VMware’s management products will also require an upgrade of your license key to vCloud Suite 7 or later. Upgrading to vCloud Suite 2017 is encouraged to leverage the vRealize Suite 2017 multi-vendor hybrid cloud management platform. You can reference the VMware Lifecycle Product Matrix to check the EOGS date for each version of the products in the bundle and the VMware Product Interoperability Matrices for the product version compatibility.
This product is embedded in the vSphere 5.5 kernel and by upgrading vSphere you will also upgrade vSAN to a newer release. You will need to upgrade your vSAN 5.5 license key to a newer release license key. Please confirm hardware compatibility by referencing the vSAN Compatibility Guide and if necessary, make appropriate hardware upgrades as needed to maintain compatibility.
If you are using vSphere 5.5 or vCloud Suite 5, please contact your VMware account team or a VMware Partner with any questions and to begin an upgrade plan.

Announcing the faster, more cost effective and more secure VMware vSAN 6.6! Learn what’s new, the benefits, and incentives at the Launch Resource Center:
Join me and my special guest Steve Tuomey to discuss the VSAN 6.2 architecture, including hybrid and all flash utilization.
This video shows you how to create or modify a Virtual SAN storage policy, how to assign a policy to VMs and other objects, and how to check policy compliance.
The Storage and Availability solutions team is excited to announce that vSAN 6.2 was named the overall winner in the Software-Defined Technology category for the CRN 2016 Products of the Year Awards! We are extremely humbled by this recognition and couldn’t be more proud of the team.
CRN’s annual Products of the Year Awards are given to standout products and services that represent best-in-breed technological innovation backed by a supportive channel partner program. For the first time, CRN did the judging a little differently. CRN editors selected five finalists among 17 technology categories and then asked solution providers to rate the products to determine a winner based on the subcategories of Technology, Revenue and Profit, and Customer Demand. The finalists and winners were originally selected from a survey that netted more than 5,000 responses. This captured real-world satisfaction among customers and partners.
vSAN 6.2 introduced key space efficiency features like deduplication, compression and erasure coding including Quality of Service (QoS) and Software Checksum. With vSAN’s fast pace of innovation, the storage and Availability Solutions team introduced vSAN 6.5 which GA’d on November 15, 2016 and introduced features like: 2-node direct connect which could save customers up to 20% per ROBO site, full-featured PowerCLI for scalability and ease of enterprise-class automation and support for next-gen hardware including large capacity drives with 512e support.
This rapid innovation, has led to rapid adoption of vSAN. We’re adding ~100 customers per week and this positive recognition is consistent with the customer feedback we’ve been getting from customers who have adopted vSAN 6.2. Yellow Pages Canada is one such customer who adopted vSAN all-flash to power their front end apps, search engines, BI and SQL databases and to support their mixed workload environments.

v 6.2.0 / March 2016 / version 0.30
VMware Virtual SAN 6.1, shipping with vSphere 6.0 Update 1, introduced a new feature called VMware Virtual SAN Stretched Cluster. Virtual SAN Stretched Cluster is a specific configuration implemented in environments where disaster/downtime avoidance is a key requirement. This guide was developed to provide additional insight and information for installation, configuration and operation of a Virtual SAN Stretched Cluster infrastructure in conjunction with VMware vSphere. This guide will explain how vSphere handles specific failure scenarios and discuss various design considerations and operational procedures.
Virtual SAN Stretched Clusters with Witness Host refers to a deployment where a user sets up a Virtual SAN cluster with 2 active/active sites with an identical number of ESXi hosts distributed evenly between the two sites. The sites are connected via a high bandwidth/low latency link.
The third site hosting the Virtual SAN Witness Host is connected to both of the active/active data-sites. This connectivity can be via low bandwidth/high latency links.
Each site is configured as a Virtual SAN Fault Domain. The nomenclature used to describe a Virtual SAN Stretched Cluster configuration is X+Y+Z, where X is the number of ESXi hosts at data site A, Y is the number of ESXi hosts at data site B, and Z is the number of witness hosts at site C. Data sites are where virtual machines are deployed. The minimum supported configuration is 1+1+1 (3 nodes). The maximum configuration is 15+15+1 (31 nodes).
In Virtual SAN Stretched Clusters, there is only one witness host in any configuration. A virtual machine deployed on a Virtual SAN Stretched Cluster will have one copy of its data on site A, a second copy of its data on site B and any witness components placed on the witness host in site C. This configuration is achieved through fault domains alongside hosts and VM groups, and affinity rules. In the event of a complete site failure, there will be a full copy of the virtual machine data as well as greater than 50% of the components available. This will allow the virtual machine to remain available on the Virtual SAN datastore. If the virtual machine needs to be restarted on the other site, vSphere HA will handle this task.
Virtual SAN Stretched Cluster configurations require vSphere 6.0 Update 1 (U1) or greater. This implies both vCenter Server 6.0 U1 and ESXi 6.0 U1. This version of vSphere includes Virtual SAN version 6.1. This is the minimum version required for Virtual SAN Stretched Cluster support.
vSphere & Virtual SAN
Virtual SAN version 6.1 introduced features including both All-Flash and Stretched Cluster functionality. There are no limitations on the edition of vSphere used for Virtual SAN. However, for Virtual SAN Stretched Cluster functionality, vSphere DRS is very desirable. DRS will provide initial placement assistance, and will also automatically migrate virtual machines to their correct site in accordance to Host/VM affinity rules. It can also help will locating virtual machines to their correct site when a site recovers after a failure. Otherwise the administrator will have to manually carry out these tasks. Note that DRS is only available in Enterprise edition and higher of vSphere.
Hybrid and All-Flash support
Virtual SAN Stretched Cluster is supported on both hybrid configurations (hosts with local storage comprised of both magnetic disks for capacity and flash devices for cache) and all-flash configurations (hosts with local storage made up of flash devices for capacity and flash devices for cache).
VMware supports Virtual SAN Stretched Cluster with the v2 on-disk format only. The v1 on-disk format is based on VMFS and is the original on-disk format used for Virtual SAN. The v2 on-disk format is the version which comes by default with Virtual SAN version 6.x. Customers that upgraded from the original Virtual SAN 5.5 to Virtual SAN 6.0 may not have upgraded the on-disk format for v1 to v2, and are thus still using v1. VMware recommends upgrading the on-disk format to v2 for improved performance and scalability, as well as stretched cluster support. In Virtual SAN 6.2 clusters, the v3 on-disk format allows for additional features, discussed later, specific to 6.2.
Features supported on VSAN but not VSAN Stretched Clusters
The following are a list of products and features support on Virtual SAN but not on a stretched cluster implementation of Virtual SAN.
- SMP-FT, the new Fault Tolerant VM mechanism introduced in vSphere 6.0, is supported on standard VSAN 6.1 deployments, but it is not supported on stretched cluster VSAN deployments at this time. *The exception to this rule, is when using 2 Node configurations in the same physical location.
- The maximum value for NumberOfFailuresToTolerate in a Virtual SAN Stretched Cluster configuration is 1. This is the limit due to the maximum number of Fault Domains being 3.
- In a Virtual SAN Stretched Cluster, there are only 3 Fault Domains. These are typically referred to as the Preferred, Secondary, and Witness Fault Domains. Standard Virtual SAN configurations can be comprised of up to 32 Fault Domains.
- The Erasure Coding feature introduced in Virtual SAN 6.2 requires 4 Fault Domains for RAID5 type protection and 6 Fault Domains for RAID6 type protection. Because Stretched Cluster configurations only have 3 Fault Domains, Erasure Coding is not supported on Stretched Clusters at this time.
Introducing Virtual SAN 6.5
VMware Virtual SAN 6.5 is the latest release of the market-leading, enterprise-class storage solution for hyper-converged infrastructure (HCI).
Virtual SAN continues to see rapid adoption with more than 5000 customers utilizing the solution for a number of use cases including mission-critical production applications and databases, test and development, management infrastructures, disaster recovery sites, virtual desktop deployments, and remote office implementations. Virtual SAN is used by 400+ Fortune-1000 organizations across every industry vertical in more than 100 countries worldwide.
Let’s take a look at the new features included with Virtual SAN 6.5…
The Virtual SAN 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 Virtual SAN API and PowerCLI: Creating a Cluster and Configuring Virtual SAN PowerCLI can be used to monitor the health of a Virtual SAN 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 Virtual SAN licensing model to account for this change in the industry. All Virtual SAN 6.5 licenses include support for both hybrid and all-flash configurations. Please note, however, that deduplication, compression, and erasure coding still require Virtual SAN 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.
Virtual SAN 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 Virtual SAN licensing change.
Virtual SAN 6.5 extends workload support to physical servers and clustered applications with the introduction of an iSCSI target service. Virtual SAN continues its track record of being radically simple by making it easy to access Virtual SAN storage using the iSCSI protocol with just a few vSphere Web Client mouse clicks. iSCSI targets on Virtual SAN are managed the same as other objects with Storage Policy Based Management (SPBM). Virtual SAN 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 Virtual SAN for physical server workloads and clustered applications can reduce or eliminate the dependency on legacy storage solutions while providing the benefits of Virtual SAN such as simplicity, centralized management and monitoring, and high availability.
Scale To Tomorrow
New application architecture and development methods have emerged that are designed to run in today’s mobile-cloud era. For example,“DevOps” is a term that describes how these next-generation applications are developed and operated. “Container” technologies such as Docker and Kubernetes are a couple of the many solutions that have emerged as options for deploying and orchestrating these applications. Cloud native applications naturally require persistent storage just the same as traditional applications. Virtual SAN is an excellent choice for next-generation cloud native applications. Here are a few examples of the efforts that are underway:
vSphere Integrated Containers Engine is a container runtime for vSphere, allowing developers familiar with Docker to develop in containers and deploy them alongside traditional virtual machine workloads on vSphere clusters. vSphere Integrated Containers Engine enables these workloads to be managed through the vSphere GUI in a way familiar to vSphere admins. Availability and performance features in vSphere and Virtual SAN can be utilized by vSphere Integrated Containers Engine just the same as traditional virtual machine environments.
Docker Volume Driver for vSphere enables users to create and manage Docker container data volumes on vSphere storage technologies such as VMFS, NFS, and Virtual SAN. This driver makes it very simple to use containers with vSphere storage and provides the following key benefits:
– DevOps-friendly API for provisioning and policy configuration.
– Seamless movement of containers between vSphere hosts without moving data.
– Single platform to manage – run virtual machines and containers side-by-side
Next-Gen Hardware Support
vSphere 6.5 and Virtual SAN 6.5 also introduce support for 512e drives, which will enable larger capacities to meet the constantly growing space requirements of today’s and tomorrow’s applications. New hardware innovations such as NVMe provide dramatic performance gains for Virtual SAN with up to 150k IOPS per host. This level of performance combined with the ability to scale up to 64 hosts in a single cluster sets the stage for running any app, any scale on Virtual SAN.
