VMware vSAN Design Guide. Now featuring vSAN 7 Update 1 recommendations. Note, this guide was formerly known as the vSAN Design and sizing guide, but while some sizing aspects of design will be included, it is encouraged to use vSAN sizing tool for the most current and accurate sizing.
VMC on AWS introduced the TRIM/UNMAP feature flag with the M12 release. This is the same functionality that was introduced in vSAN 6.7U1. You can have it enabled in your M12 and newer SDDC by requesting enablement of the TRIM/UNMAP feature flag in chat support.
Previously iSCSI on vSAN was not supported. Why was this? Normally vSAN Stretched clusters implement a site locality construct to avoid unnecessary inter-site latency being added to the read IO path (They prefer all reads from the local site). The challenge came from the fact that the iSCSI […]
Should you use Eager Zero Thick? For VMFS, maybe? but for vSAN probably not. Ok, I’ll agree I probably owe an explanation of why. A quick history lesson of the 3 kinds of VMDKs used on VMFS. thin: Space is not guaranteed, it’s consumed as the disk is written to. thick (Sometimes called Lazy […]
One of the new, exciting features in vSAN 7.0U1 is the extension to vSAN File Service. As well as supporting NFS v3 & v4.1, we now also support SMB (Server Message Block) protocols v2 & v3. This protocol is commonly associated with Windows File Shares. In this post, I will go through the new […]
Upgrade Economics Patching and upgrading in a data center is something that is sometimes viewed purely as a “cost” based on the manpower required to upgrade an environment. While VMware has a lot of great options to reduce this (VMware Cloud Foundation, VMware Cloud, vSphere Lifecycle Manager) […]
There are multiple ways to generate email alerts, from VMware vSAN. vRealize Operations at scale is a powerful tool that allows multicluster and Datacenter to roll up, LogInsight can generate email alerts, SNMP based alerts, and use webhooks to push alerts into several other operational tools.
One of the new features introduced in vSphere 7.0U1 is HCI-Mesh, the ability to remotely mount vSAN datastores between vSAN clusters managed by the same vCenter Server. My buddy and colleague Duncan has done a great write-up on this topic on his yellow-bricks blog. In this post, I am going to […]
With the release of vSAN 7.0U1, a major change was made with regards to what was termed “slack space” requirements. This basically referred to how much space should be set aside on the vSAN datastore for operational and rebuild purposes. I have had a few queries about this recently, so I thought I would take the opportunity to highlight some of the capacity management features now available in vSAN. This would also be a good time to revisit the advanced options for Automatic Rebalance, as…Read More
Advertise here with BSA I wrote a vSAN HCI Mesh Considerations blog post a few weeks ago. Based on that post I received some questions, and one of the questions was around vSphere HA configurations. Interestingly I also had some internal discussions around how vSAN HCI Mesh and HA were integrated.
In this blog post I’m going to show you how can enable vSAN 7.0 File Service. This article doesn’t cover of vCenter, vSphere ESXi and vSAN upgrade process, just show you how can configure one of new capability of vSAN 7.0. I don’t want to rob your time; let’s jump in!
