A vSAN stretched cluster must meet certain basic networking requirements. Management network requires connectivity across all three sites, using a Layer 2 stretched network or a Layer 3 network. The vSAN network requires connectivity across all three sites. It must have independent routing and connectivity between the data sites and the witness host.

Those racks should be spread out as much as is possible. The only requirement is a sub-1ms RTT between hosts in the cluster. RAID-1 (mirroring) in vSAN employs a 2 n +1 host or fault domain algorithm, where n is the number of failures to tolerate. RAID-5/6 (erasure coding) in vSAN employs a 3+1 or 4+2 host or fault domain requirement, depending on 1 or 2 failures to tolerate respectively. 2016-08-24 With Update 2 the ability to mount remote vSAN datastore from non-vSAN bases vSphere clusters will be possible with improved scalability up to 128 hosts connected to a remote vSAN datastore. Also added is storage policy integrations with vSAN datastores for DD&C, or … 2018-05-06 ESXi hypervisor should be installed on each host.

The configuration is 1+1+1. This is commonly referred to as a 2 Node configuration. The two-node vSAN architecture builds on the concept of Fault Domains where each of the two VMware ESXi™ hosts, represent a single Fault Domain. In vSAN architecture, the objects that make up a virtual machine are typically stored in a redundant mirror across two Fault Domains, assuming the Number of Failures to Tolerate is equal to 1. Before vSAN 7, a common operational procedure when replacing a witness host appliance in 2-node and stretched clusters was to manually force a "Repair objects immediately" operation to regain full compliance as quickly as possible. Otherwise, the new witness host would not initiate a metadata resync until the 60-minute delay timer expired. Upgrading vSAN 2-node Clusters with a Shared Witness from 7U1 to 7U2 Upgrading vSAN 2-node Clusters with a Shared… There is a special consideration when it comes to 2-node clusters with a shared witness host.

4 Mar 2020 It is StarWind VSAN which pulls the local storage of each host and creates a shared storage pool. The only drawback when using ESXi free

IF your vSAN is all-flash, you will also want to enable deduplication and compression. Optional encryption is also available.

So, for tolerating two failures, VSAN creates 2+1 (3) copies of the object, and 2x2+1 (5) hosts contributing with storage are necessary. The VSAN 3-node architecture with a default failure policy is set to FTT=1 (two copies of data on two different hosts + a witness component on another host). While the maximum size for a standard vSAN cluster is 64 hosts, the minimum number of hosts required in a vSAN cluster depends on the data placement and resilience settings assigned to the objects using storage policies. Understanding the desired protection levels for your VMs will help in determining the minimum host count for a vSAN cluster.

2017-03-10 · The 2-node vSAN will need 2 ESXi hosts at the remote site, but there may be a 3rd physical server that could be used for hosting vCenter as well as the witness appliance. If you are using a vSphere Essentials license, you will not be able to add the witness appliance as vSphere Essentials can only manage 3 hosts. Begin the vSAN configuration. Select configure two host vSAN cluster. IF your vSAN is all-flash, you will also want to enable deduplication and compression.

Optional encryption is also available. Verify that vSAN is enabled on the vmkernel adapters. If not, you will need to go back and do this on the esxi hosts. Each object stored on vSAN will have a minimum of two data components mirrored across two of the hosts, plus a witness component located on the third host. There are circumstances in which it may be desirable to deploy the vSphere hosts containing VM data in one data center and to maintain a dedicated witness host in an offsite location.
