Overview vSAN Health check is a cloud-connected health validation framework. It helps ensure that vSAN is running optimally and configured according to VMware best practices. VMware recommends validating that all health checks are green while deploying production workloads to vSAN. Health checks have varying levels of importance. As an example, a vSAN network partition impacts Read more...
The post, “Multi-Cluster Upgrading Strategies for vSAN” described an approach for upgrading vSAN in a data center comprising of several vSAN clusters. But what about environments running large vSAN clusters? How should an upgrade of a large vSAN cluster be approached? Let’s take a look at this in more detail. Standard vSAN clusters can range Read more...
Welcome to the #StorageMinute series where we deliver topics via bite-size content. In this edition, we will take a look at how VMware Cloud Foundation is built on vSAN. VMware Cloud Foundation VMware Cloud Foundation is the most comprehensive hybrid cloud architecture. It provides a complete set of software-defined services for compute, storage, networking, and cloud Read more...
While VMware continues to introduce all new levels of performance, capabilities, robustness, and ease-of-use to vSAN, the respective vSAN clusters must be updated to benefit from these improvements. While the upgrading process continues to be streamlined, environments running multiple clusters of vSAN can benefit from specific practices that will deliver a more efficient upgrade experience. Read more...
We’re back with our monthly tweet chat! This month we discussed Site Recovery Manager (SRM) 8.2 and recent updates. We were joined by Virtually Speaking host, Pete Flecha, and VMware Availability tech guru, Cato Grace! Catch up on the SRM hour below. Q1: Can you give a brief description of Site Recovery Manager Read more...
vSAN Object Types There are a number of different object types within VMware vSAN. The most common ones are: VM home namespace – Location for VM configuration and log files. VM swap object – Created for the VM swap file (only created when the VM is powered on). VMDK – Stores the data that is Read more...
Are you looking for code samples as they relate to VMware Storage & Availability? Are you looking for an ad-hoc script to report the overall storage utilization on your vSAN Cluster? Or maybe a script to automate the configuration VMkernel ports services such as vSAN or Replication? StorageHub now includes storage-centric community generated code Read more...
The vSAN performance service provides storage-centric visibility to a vSAN cluster. It is responsible for collecting vSAN performance metrics, and will present them in vCenter. A user can set the selectable time window from 1 hour to 24 hours, and the data presented uses a 5-minute sampling rate. The data may be retained for up Read more...
When vSAN was added to the vSphere 6.0 STIG Framework, it was the 1st and only HCI solution that was included in a publicly available DISA STIG. As of 12 JUN 2019, the vSphere 6.5 STIG Framework was released. More than 2 years later, vSphere and vSAN are still the only HCI solution that is Read more...
Troubleshooting performance issues can be a complex undertaking for many administrators, regardless of the underlying infrastructure and topology. A distributed storage platform like vSAN introduces other elements that can influence performance as well, and the practices for troubleshooting should accommodate for those considerations. The guidance provided below will help an administrator use the metrics Read more...
