No network Adapter issue actually will be happened during installation, if the server has no adapter or the adapter driver is not loaded or the image is not contains of any compatible adapter driver, ESXi installer does stop installation and prompt
Controlling resource usage by the metrics, it’s a key to keep your virtual infrastructure up and optimized and also keep your customer happy. Veeam ONE alarm will help you to controlling the metrics and resources.
Before create the alarms, we should know why I/O is important to us? And what is impact of generating lot of I/O by virtual machines?
Veeam ONE Reporter Collection Job Veeam ONE Reporter collection job is a scheduled job to gathering virtual infrastructure information to providing reports for administrators about virtual infrastructure performance, issues and capacity planning. Sometimes, the job will be failed cause of some issues in the Veeam Reporter service and an error will indicate on Veeam ONE Monitor Client. Administrators should care about the issue because the error means that virtual infrastructure information is out of date and any report is unusable. Troubleshooting Step 1: At first step, checking “Veeam ONE Reporter Server” service is very important. Check the service and if it’s stopped, start the service and if it’s started , restart the service and run “Object Properties Collection Task” from Veeam ONE Reporter portal. Wait to job is completed and if issue not resolve go to the next step. Step 2: If stop/start the service didn’t resolve issue, restarting the server is second solution because of OS issues. Run “Object Properties Collection Task” from Veeam ONE Reporter portal, wait to job is completed and if issue not resolve go to the next step. Step 3: If step 1 and step 2 didn’t help to resolve issue, the monitor user permission...
VMware Virtual SAN or vSAN is a software-defined storage or hyper-converged infrastructure and it’s fully integrated with VMware vSphere. vSAN create a software defined storage area from local storage devices or direct attached devices. vSAN supports vSphere features that the features needs shared storage such as HA and DRS. vSAN is also fully integrated with desktop solutions and any virtual machine will be provisioned and protected on vSAN.
ESXi PCI Passthrough This is a combination hardware and software feature on hypervisors to allows VMs to use PCI functions directly And we know it as VMDirectPath I/O in vSphere environment. VMDirectPath I/O needs some requirements to work perfectly, please read this KB for more information, as we read it! https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2142307 There is also some limitation when using VMDirectPath I/O and the below features will unavailable: Hot adding and removing of virtual devices Suspend and resume Record and replay Fault tolerance High availability DRS (limited availability. The virtual machine can be part of a cluster, but cannot migrate across hosts) Snapshots I couldn’t find any other limitation specially about memory size, so now why we couldn’t use more than 790 GB to 850 GB of our server memory capacity?! Anyway, let’s review our test scenario! Our Test Scenario We have some Sun X4-8 servers with the below specifications: CPU: 8 x E7-8895 v2 Local Disk: 8 x 600 GB SAS Disk Memory: 48 x 16 GB – Totally 768 GB PCI Devices: 2 x QLogic 2600 16 Gb – 2 Ports (HBA) 2 x Intel 82599EB 10 Gb – 2 Ports (Network) Embedded Devices: 2 x Intel I350 1Gb ESXi 6.x U2 has...
