Implement and configure AWS Backup for VMware Cloud on AWS VM workloads

In our previous post we saw the design of the AWS Backup on VMC. In this post we’re going through the implementation steps As per the design and best practice, we are going to use the ENI for the Backup traffic CREATE A VPC ENDPOINT  TO CREATE AN INTERFACE ENDPOINT FOR AN AWS SERVICE 1. Open the Amazon VPC console at    2. In the navigation pane, choose Endpoints 3. Choose Create endpoint 4. Name the endpoint   5. For Service category, choose AWS services 6. For Service name, search “ Backup ” and select “ backup-gateway ” service from the dropdown 7. For VPC, select the VPC which we used for SDDC deployment and extension 8. To create an interface endpoint for Amazon S3, you must “uncheck” Additional settings, Enable DNS name. This is because Amazon S3 does not support private DNS for interface VPC endpoints 9. For  Subnets , select one subnet per Availability Zone which we used for SDDC VMC selection  10. For Security group , sel

Troubleshooting Storage Performance in vSphere

When we troubleshoot performance related issues, the first think which would hit our mind it "Storage". So let's have a sneak peak about the basic troubleshooting of the storage related issues.  Poor storage performance is generally the result of high I/O latency. vCenter or esxtop will report the various latencies at each level in the storage stack from the VM down to the storage hardware.  vCenter cannot provide information for the actual latency seen by the application since that includes the latency at the Guest OS and the application itself, and these items are not visible to vCenter. vCenter can report on the following storage stack I/O latencies in vSphere.  Storage Stack Components in a vSphere environment GAVG (Guest Average Latency) total latency as seen from vSphere KAVG (Kernel Average Latency) time an I/O request spent waiting inside the vSphere storage stack.  QAVG (Queue Average latency) time spent waiting in a queue inside the vSphere St
