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 Nakivo! After having the solution perfectly deployed and having performed a Backup Job, In this other post we will see how to perform a replication task! This will allow us to have our virtual machine environment fully replicated, thus in case of failure of the data center or main server, We will be able to lift the entire infrastructure in a matter of seconds!
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!
This bootloader will allow us, among other of its many features, to boot from USB devices on computers that their BIOS does not support (even in virtual machines, That sometimes we've needed it). It is downloaded in ISO format and we will connect it to the VM at boot.
If a few days ago, we saw the new VMware Fusion 3.0, today we will get up to date with the Parallels Desktop product 5 for MAC. Seemingly, both programs, Direct competition, they seem to have the same functionalities, So we will try to reveal the differences so that we can lean towards one of the two. First of all, is to request a demo license to test it (They are a bit rats, They only give us 14 days), If we like it, then we can buy it ;). To do this,, we must register on the Parallels website
