It is based on CentOS and is a custom operating system with everything that’s needed to manage your virtual servers. It orchestrates the networking, backups, storage, etc. It has zero overhead on top of that. The result is a blazing fast hypervisor.
edgeLinux OS supports two types of virtualization to create your antlets. While each antlet is a complete Virtual Private Server (VPS), LXC antlets use OS-based virtualization, a.k.a. containerization (popularized by docker), whereas KVM antlets use hardware-based virtualization with QEMU and KVM. For most cases, use LXC-based antlets because they create the least overhead and save resources including electricity. In that way, your Antsle is a green datacenter.
For storage, we use mirrored ZFS pools. ZFS is an advanced, feature rich file system designed to never allow any data loss or inconsistent state on the storage media. Combined with mirroring, our ZFS-based storage architecture offer excellent fault-tolerance and flexibility. We just thought your data is important – so we better keep it safe.
We use a ZFS pool (zpool) named “antlets” to store your antlets as well as the templates the antlets are created from. Try a
zfs list -t allto inspect the layout of ZFS file systems. The HDD add-on resides on a separate zpool named
Each antlet gets its own ZFS file system in the antlets pool, so it’s completely separated from the rest of the system (including other antlets). Mirroring, compression etc is all handled by ZFS inside edgeLinux OS and is completely transparant to the antlets themselves. In plain English: each and every antlet gets isolation, mirroring and compression for free, without having to take care of it in any way.
We have an integrated, internal DHCP server in edgeLinux OS, and each antlet will pull it's IP address from that DHCP server - unless you create a bridge. This DHCP server will assign IP addresses based on Mac addresses:
b2:61:6e:73:6c:0a will receive 10.1.1.10
b2:61:6e:73:6c:0b will receive 10.1.1.11
b2:61:6e:73:6c:0c will receive 10.1.1.12
b2:61:6e:73:6c:0d will receive 10.1.1.13
In our pre-defined templates, we're always using those Mac addresses, and through our template XMLs we make sure that one of these MACs will be assigned.
Check your settings tab in antMan, your version of antMan should should be 2.2.1 (or higher). Why is this important? Any antlet backups taken before this version can not be restored on edgeLinux 2.0. If your antMan is not up to date then run
upgrade-antmanin your console before taking backups in step two.
Watch this 1 minute video or read our docs article for a guide on how to back up and restore antlets. This tutorial assumes you will use the Antsle Cloud as your storage backend. Backups come with antMan Essential, Grow or Scale. You can see our plans and pricing here. Once backups are enabled you can back up your antlets.
At the on-boarding screen, select “this is Antsle hardware” and follow the prompts. This will give your new installation the same serial number and license as the original.
You must also register the Antsle on antHill when prompted in the on-boarding process. This will allow antHill to make the connection between your backups and this new server.
