 Xen Orchestra itself is built as a modular solution. Each part has its role:
+
 - The core is "[xo-server](https://github.com/vatesfr/xen-orchestra/tree/master/packages/xo-server/)" - a daemon dealing directly with XenServer or XAPI capable hosts. This is where users are stored, and it's the center point for talking to your whole Xen infrastructure.
-- The web interface is "[xo-web](https://github.com/vatesfr/xen-orchestra/tree/master/packages/xo-web)" - it runs directly from your browser. The connection with ```xo-server``` is done via *WebSockets*.

 We have other modules as well (like the LDAP plugin for example). It allows us to use this modular architecture to add further parts as we need them. It's completely flexible, allowing us to adapt Xen Orchestra to every existing workflow.

 # User authentication

 Xen Orchestra supports various types of user authentication, internal or even external thanks to the usage of the [Passport library](http://passportjs.org/).
 
 There are 2 types of XO users:
 
-* admins, with all rights on all connected resources
-* users, with no rights by default
+- admins, with all rights on all connected resources
+- users, with no rights by default
 
 All users will land on the "flat" view, which displays no hierarchy, only all their visible objects (or no object if they are not configured).

 ACLs will thus apply only to "users".

 ### VDI chain protection
 
-This means your previous VM disks and snapshots should be "merged" (*coalesced* in the XenServer world) before we can take a new snapshot. This mechanism is handled by XenServer itself, not Xen Orchestra. But we can check your existing VDI chain and avoid creating more snapshots than your storage can merge. Otherwise, this will lead to catastrophic consequences. Xen Orchestra is the **only** XenServer/XCP backup product dealing with this.
+Backup jobs regularly delete snapshots. When a snapshot is deleted, either manually or via a backup job, it triggers the need for Xenserver to coalesce the VDI chain - to merge the remaining VDIs and base copies in the chain. This means generally we cannot take too many new snapshots on said VM until Xenserver has finished running a coalesce job on the VDI chain.

If we don't, this will lead to catastrophic consequences. Xen Orchestra is the **only** XenServer/XCP backup product that takes this into account and offers protection.

+- `The Snapshot Chain is too Long`

 ### Troubleshooting a constant VDI Chain Protection message (XenServer failure to coalesce)
 
- As previously mentioned, this message can be normal and it just means XenServer needs to perform a coalesce to merge old snapshots. However if you repeatedly get this message and it seems XenServer is not coalescing, You can take a few steps to determine why.  
+As previously mentioned, this message can be normal and it just means XenServer needs to perform a coalesce to merge old snapshots. However if you repeatedly get this message and it seems XenServer is not coalescing, You can take a few steps to determine why.
 
-First check SMlog on the XenServer host for messages relating to VDI corruption or coalesce job failure. For example, by running `cat /var/log/SMlog | grep -i exception` or `cat /var/log/SMlog | grep -i error` on the XenServer host with the affected storage.

+Coalesce jobs can also fail to run if the SR does not have enough free space. Check the problematic SR and make sure it has enough free space, generally 30% or more free is recommended depending on VM size. You can check if this is the issue by searching `SMlog` with `grep -i coales /var/log/SMlog` (you may have to look at previous logs such as `SMlog.1`).
 
-You can check if a coalesce job is currently active by running `ps axf | grep vhd` on the XenServer host and looking for a VHD process in the results (one of the resulting processes will be the grep command you just ran, ignore that one).  
+You can check if a coalesce job is currently active by running `ps axf | grep vhd` on the XenServer host and looking for a VHD process in the results (one of the resulting processes will be the grep command you just ran, ignore that one).
 
 If you don't see any running coalesce jobs, and can't find any other reason that XenServer has not started one, you can attempt to make it start a coalesce job by rescanning the SR. This is harmless to try, but will not always result in a coalesce. Visit the problematic SR in the XOA UI, then click the "Rescan All Disks" button towards the top right: it looks like a refresh circle icon. This should begin the coalesce process - if you click the Advanced tab in the SR view, the "disks needing to be coalesced" list should become smaller and smaller.
 
+As a last resort, migrating the VM (more specifically, its disks) to a new storage repository will also force a coalesce and solve this issue. That means migrating a VM to another host (with its own storage) and back will force the VDI chain for that VM to be coalesced, and get rid of the `VDI Chain Protection` message.

 ### Parse Error
 
 This is most likely due to running a backup job that uses Delta functionality (eg: delta backups, or continuous replication) on a version of XenServer older than 6.5. To use delta functionality you must run [XenServer 6.5 or later](https://xen-orchestra.com/docs/supported-version.html).
