For a few months I was tinkering with a local and open source AI; And I wanted to share with you a little in a series of posts some of its possibilities in our day to day. But in this first document we will see how we can set it up and some basic notions of its possibilities.
As we know, Volumio is one of the best audio control systems (for the Home, office…) But for now it has a small limitation, which is only allowed to be installed in physical (Raspberry Pi, X32/X64 or on the ASUS Tinkerboard). But, and if we want to provide it with high availability, Fast backup/restore… Or wow, have the advantages of being one more VM in our environment…
We continue with the series of documents on Nakivo, after already having copies and replicas of our infrastructure with Nakivo Backup & Replication what we have left? Test recovery! Which will be the first thing we are going to try, See what types of recoveries we have and how to recover a virtual machine!
If we want to provide full high availability to a virtual machine, we will enable Fault Tolerance or FT. With FT we will be able to allow a VM in the event of a failure of a host or the storage where it is executed to fall, Don't worry., since the VM is replicated to another host and another datastore. The magic of FT will cause us to only lose a single packet against the VM!
Continuing with the VMware vSphere series of posts 6.5, Today we will look at something quite important, Replicating virtual machines to our virtual infrastructure, How to protect ourselves against a disaster in our datacenter. We will initially configure the requirements and then we will see how to replicate a virtual machine and how to make a recovery or failover if necessary!
We will be able to continue with another automatic update process, and it is only once we have all the hosts updated to the version 6.5, We will need to update (in this order) VMware Tools and Virtual Machine Hardware. The latter perhaps more optional. We will do all this through Update Manager which, as we know, is embedded in the vCenter Server Appliance 6.5
In this document we will monitor interesting elements that we will obtain from our VMware vSphere-based virtual machines, centralizing in Nagios the checks we do to manage its values, Get alerts or generate graphs of your consumption. We will see, among other checks, in the VMs obtaining the values of their CPU Ready, CPU Wait, Memory Overhead, Memctl, Balloning, Write or read IOs…
For all those who don't know him here's this post, Introducing the Fortinet Virtual Appliance, the Fortigate-VM firewall, in virtual machine format will provide us with all the advantages of having the Fortigate firewall virtualized in our network (high availability, Cross-network FW, Backup/Replica…) Of course,, only for VMware vSphere environments!
Para continuar nuestra migración a vSphere 5, una vez que ya tengamos el servidor VMware vCenter en la versión 5, hayamos actualizado a VMware Update Manager 5 y todos nuestros host ESXi esten ya con el hipervisor ESXi 5, we will be able to upgrade the VMware Tools to the virtual machines as well as then upgrade the virtual hardware version of the version 4 or 7 to the version 8. Lo podremos hacer de manera manual MV por MV o automatizarlo con Update Manager y actualizarlo en nuestro entorno de forma ordenada.
One of the new features of VMware vSphere is the ability to give physical devices from hosts to virtual machines, This ensures that the driver of the virtual operating system, Directly access the physical device in question, The advantages of course is the increased performance of the device, as latencies are reduced. Latest version of VMware Tools required, it should also be taken into account that they can only be assigned 2 per virtual machine and 8 Per Host. And logically such a virtual machine will lose all the advantages of moving to other hosts, since we are assigning a physical device of a specific host. This is called VMDirectPath I/O.
