Vmware Vsan Licensing Guide

Vmware Vsan Licensing Guide – This second post in the new lab series provides instructions for installing the latest version of vSAN 7. At the time of writing the latest version of vSAN is vSAN 7.0 Update 1. See vSphere 7 and vSAN 7 New Features Headline to read what’s new. .

VMware vSAN is a software-defined storage solution built directly into the vSphere hypervisor. vSAN enables aggregation of local or directly attached devices and aggregates them across hosts in a vSphere cluster to provide a shared storage pool. Performance is abstracted from the underlying hardware and managed at the software level in vCenter to provide granular policy-based access and controls. Seamless scaling can be achieved by adding more ESXi hosts, either in the same cluster or a new cluster, and scaled up by adding more disks to existing hardware. Multiple vSAN clusters can be created and managed on a single vCenter Server. Because vSAN is already implemented directly in ESXi, enabling functionality simply requires planning and enabling configuration, along with the appropriate VMware vSAN licenses.

In this example, vSAN is configured in a lab environment using a 2-host cluster (Intel NUC Bean Canyon) running vSphere 7 U1C, with a third node acting as a vSAN witness. As of vSAN 7.0 U1 a witness device can support up to 64 2-node clusters. If you’re looking for more information on running vSphere Lab on an Intel NUC range, check out virten.net’s VMware Homelab section, which has great guides and resources.

VSAN can be configured in an all-flash or hybrid setup. In a hybrid setup, flash is used for cache with spinning disks providing tiers of capacity. Although all local capacity devices are combined and shared among cluster hosts. An optimal vSAN configuration will include hosts with the same or similar physical storage configurations, balancing storage devices consistently across the cluster. However, a host without any auxiliary storage can also join the cluster and run virtual machines. In this type of deployment, deployment planning to cover fault tolerance and protect against the loss of certain contributing nodes is of particular importance.

All hosts that contribute storage devices to the cluster must have at least one flash device for local cache, in addition to at least one capacity device. For hybrid configurations, the flash device should be at least 10% of the anticipated consumed storage in the capacity tier, and this should account for future growth to avoid performance degradation over time as consumed storage increases. The per-host cache per setup does not count toward the overall shared datastore size. The cache and capacity devices on a host form one or more disk groups, as indicated in the high-level image below. For more information on capacity and sizing considerations when designing a vSAN deployment, check out the VMware vSAN Design Guide and the Design and Sizing of a vSAN Cluster documentation.

VMware vSAN is an enterprise solution and supports all VMware features that rely on shared storage, such as high availability, distributed resource scheduling, and Storage vMotion. vSAN also includes features such as stretch clustering and fault domain implementation. Hosts in a vSAN cluster can also mount other VMFS and NFS storage, although vSAN itself does not require or rely on any type of external storage or storage area network (SAN). You can find more information in vSAN Planning and Deployment – VMware vSphere 7.0 documentation, which should be read before configuring vSAN, along with the relevant release notes – in this example I’m using vSAN 7.0 Update 1.

In this example, we use the vSphere Cluster Quickstart page to configure vSAN. Quickstart integrates the storage and networking workflows required to enable vSAN. A new cluster is created that contains 2 ESXi hosts running 7.0 U1C. The hosts are in maintenance mode and have no datastore or partition information available beyond the standard boot disk. Both hosts use PCIe flash devices in pass-through mode.

The third host will act as a witness node. The witness for a 2-host vSAN cluster must have disks available for writing metadata. At least 10 GB cache and 15 GB capacity. All 3 hosts need a configured VMkernel port. Since this is a lab environment, with limited physical connections and bandwidth, I configured the vmk management port to be used for vSAN traffic as well. A vmk port is a virtual adapter used to manage VMware service traffic for various functions. If you need help setting up the VMkernel adapter for vSAN, see the How to Configure vSAN VMkernel Networking Knowledge Base page.

Now that the VMkernel ports are set for vSAN traffic and IP reachability exists between the vSAN cluster hosts and the witness node, we can begin configuring vSAN. Select the cluster in the vSphere client and click Configure > Quickstart. For step 1, click Edit and select the vSAN service. After a few seconds, the prerequisite health checks in step 2 will be completed. If no problem, go to step 3 and click configure.

Configure network settings for the vSAN cluster. Quickstart setup uses vSphere distributed switches, which is recommended, although standard vSphere switches are also supported. In my lab, since I’ve already enabled vSAN traffic on the management port, I can skip the distributed switch settings and click Next.

Configure vSAN cluster settings such as encryption, compression, and deduplication as needed. In this example I am using Two node vSAN cluster deployment type. Click Next.

Select the disks and tiers to be claimed for the vSAN cluster. Remember that vSAN can only use local or directly attached storage and not remote storage. In this example, 2 500 GB flash devices are assigned to the capacity tier and 2 50 GB flash devices are assigned to the memory tier. The total of the claimed disks is 1.07 terabytes. It does not provide any protection against component failure and is for laboratory purposes only. I accept the recommended configuration and click Next.

Since my vSAN cluster is only 2 nodes, I need to add a witness host. A witness host, with available disks for metadata, and a vSAN-enabled VMkernel adapter for communication, is selected and performs compatibility checks. Click next to continue.

Use the disks for the witness host, in this case I have allocated a 10 GB disk for cache tier metadata and a 15 GB disk for capacity tier metadata. Click next to continue.

Review the configured settings and click Finish to deploy the vSAN configuration. Although the Quickstart interface will very quickly return a message saying that the cluster is configured, keep an eye on the activity in the Recent Tasks section as configuration is probably still in progress.

The easiest way to check vSAN status is to select the cluster, click Monitor and scroll down to vSAN. Skyline Health shows vSAN health checks related to the cluster, you can also view physical and virtual object status, capacity and performance.

To view or manually edit cluster settings, select the cluster, click Configure, and scroll down to vSAN. Services shows the available vSAN services and their configuration, in my lab environment most of them are disabled. Disk Management shows configured disk groups and their health status. In this lab scenario I have configured only 2 fault domains.

Fault domains allow grouping of physical hosts to protect against common failures such as chassis or racks. Best practice is to configure fixed fault domains with the same number of hosts across the environment. Consider the impact on data placement and the overall number of host failures when configuring fault domains. Obviously, for a lab environment or a 2-node cluster on a small branch, setting up error domains and data availability cannot be applied in the same way as larger deployments. The following resources help design such environments:

Finally, if you want to create a new storage policy to apply to a vSAN datastore, or create multiple granular policies that can be applied at the VM or VMDK level, you can do so from the drop-down menu, Policies and Profiles, VM Storage Policies Do it. If you need more information about the policy options available, check out the VM Storage Policy Design Considerations documentation.
