I think you're confused here - ALL that HA does is restart VMs in the event of host loss. If you need a VM to survive a host failure without incident you need to use VMWare Fault Tolerance (FT). This is a licenced feature that requires at least 1Gbps of dedicated network connectivity between applicable hosts, most people use 10Gbps for this. With vSphere 6 ...
Those two stats you mention are different; it's 8 virtualised CPUs per VM and 2 physical CPU sockets that they're talking about - not the same thing. BTW if you're going with the free version have a look at THIS great new ESXi add-in that gives you a vCenter-like interface into your host via a web client - it's really new and really useful :)
Free version Hypervisor (Esxi) Version 6.0 2 (physical) CPU limit No Ram limit (removed since 5.5) Hypervisor Spec Number of cores per physical CPU: No limit Number of physical CPUs per host: No limit Number of logical CPUs per host: 480 Maximum vCPUs per virtual machine: 8 http://www.vmware.com/ap/products/vsphere-hypervisor/gettingstarted.html
The general rule is if you don't have a reason to switch back to BIOS, stick with UEFI.
In theory what you are asking should be possible. however it appears it isn't particularly well implemented by VMWare. The extended options should be query-able from the guest with VMToolsd.exe available, as you correctly say. However it doesn't seem to work. vmtoolsd.exe --cmd "info-get virtualHW.version" Should return the hardware version contained in ...
Netcat (nc) is telling you that it can't resolve the name "smtp.xxxxx.yy". That's what nc: getaddrinfo: Name or service not known means. To verify that this is the issue, I'd suggest entering the IP of your SMTP server manually in your nc command instead of the domain name. If that works, then it's definitely a DNS issue. To see what's going wrong in ...
You should use the Intel e1000 or VMware vmxnet3 adapters for your OS. Can you try adjusting the adapter type and testing again? Make sure the VMware tools are installed.
do I have to buy the exact same CPU again? If you want to run both the existing CPU and the new one then they have to be the exact same CPU. or can I buy a newer/better/different CPU? You can put in a newer one if you pull out the old one.
The VMware Fault Tolerance feature is the option that will keep a VM running in lock-step on two hosts. High-Availability just reduces downtime, but still reboots the virtual machines. However, these days, physical servers just don't fail, or at least shouldn't. What can you do to make your host servers more resilient? What was the nature of the failure?
It appears that your RAID controller have no cache. The main problem is that hardware RAID card tend to disable, by default, the disk's private DRAM cache. In short, this means that when, after some seconds (~30, to be precise) the dirty pagecache will be flushed to disk, a tons of random I/O request starts hammering your (slow) mechanical disk, killing ...
I'm not familiar with VMX Explorer, but VMWare deliberately and artificially cripples the bandwidth available to tools like scp over any management interfaces, so I suspect it is probably using something like that to transfer the files between the hosts. Don't bother spending any money on hardware for this. Instead use an approved method of transferring the ...
The server could have several IP-addresses. Following the comment of "Chopper3", you will probably see IP address of the management interface of the ESXi. To see all network adapters and their configuration (including IP-addresses), you should find the corresponding ESXi host in vSphere Web Client (Home --> Hosts and Clusters, then locate needed server). ...
Not to blow my own trumpet but I previously worked on the VMware High Availability/Disaster Recovery (Business continuity) architecture. Previously the ability to monitor both the host software (e.g. Windows/Linux) and also application level software (e.g. SQL Server/Exchange etc.) was integrated into the same application. This has been spread out between ...
It doesn't appear as though you have any write cache. Please confirm the generation and model of your server. If you don't have a Flash-backed write cache module (FBWC) on the controller that your disks are attached to, your VMware performance will suffer. The other issue here is LVM and some of the defaults that appeared in RHEL6 a few years ago. You'll ...
Possibly related. In esxi 6, changing the root password in the Vsphere client did not seem to properly take effect. I could no longer log into vsphere, but could still log into the machine console with the old password. Restarting all the management agents seemed to bring everything into line again.
you can create custom Atomic Host Images that include any RPM. http://developerblog.redhat.com/2015/01/08/creating-custom-atomic-trees-images-and-installers-part-1/
