Central Management
Details
|
Yes (XenCenter)
XenCenter is the central Windows-based multi-server management application (client) for XenServer hosts (including the open source version).
It is different to other management apps (e.g. SCVMM or vCenter) which typically have a management server/management client architecture where the management server holds centralized configuration information (typically in a 3rd party DB). Unlike these management consoles, XenCenter distributes management data across XenServer servers (hosts) in a resource pool to ensure there is no single point of management failure. If a management server (host) should fail, any other server in the pool can take over the management role. XenCenter is essentially only the client.

No
The free hypervisor license does not include a vCenter agent, so cant be added to vCenter Server but you can use the (free) vCenter client to manage the Hypervisor host(s) individually.
You can also use the vCLI to manage this edition.

Virtual and Physical
Details

Limited (plug-ins)
NEW
XenCenter focusses on managing the virtual infrastructure (XenServer host and the associated virtual machines).
XenServer 7.0 saw the introduced of System Center Operations Manager (SCOM) integration pack (via a Comtrade acquisition). This enabling the management and monitoring of XenServer hosts and VMs and is available for no additional charge for XenServer 7.x Enterprise Edition users (see http://bit.ly/2cXr14v for details)

No
No centralized management with this license

RBAC / AD-Integration
Details
|
Yes (hosts/XenCenter)
XenServer 5.6 introduced Role Based Access Control by allowing the mapping of a user (or a group of users) to defined roles (a named set of permissions), which in turn have the ability to perform certain operations. RBAC depends on Active Directory for authentication services. Specifically, XenServer keeps a list of authorized users based on Active Directory user and group accounts. As a result, you must join the pool to the domain and add Active Directory accounts before you can assign roles.
There are 6 default roles: Pool Admin, Pool Operator, VM Power Admin, VM Admin, VM Operator and Read Only - which can be listed and modified using the xe CLI.

Yes (ESXi hosts only)
There is Active Directory Integration for ESX hosts (since 4.1)

Cross-Vendor Mgmt
Details
|
No (native)
Yes (Vendor Add-On: CloudPlatform)
XenCenter only manages Citrix XenServer hosts.
Comments:
- Citrixs Desktop Virtualization product (XenDesktop, fee based add-on) supports multiple hypervisors (ESX, XenServer, Hyper-V)
- The Citrix XenServer Conversion Manager in 6.1 now enables batch import of VMs created with VMware products into a XenServer pool to reduce costs of converting to a XenServer environment).

No
The VMware XVP tool requires vCenter (not available for the free Hypervisor) and the VMware Go manage VMware environments only

Browser Based Mgmt
Details
|
Not directly with XenCenter but possible with XenOrchestra (Open Source)
More info: http://bit.ly/2m7FVIG
Web Self Service (retired with the launch of XenServer 6.2) was a lightweight portal which allowed individuals to operate their own virtual machines without having administrator credentials to the XenServer host. For large infrastructures, OpenStack is a full orchestration product with far greater capability; for a lightweight alternative, xvpsource.org offers a free open source product.
Related Citrix products have browser based access, for example Storefront (next generation of Web Interface)
XenOrchestra is a web interface to visualize and administrate your XenServer (or XAPI enabled) hosts. No agent is requiered to make it work. It aims to be easy to use on any device supporting modern web technologies (HTML 5, CSS 3, JavaScript) such as your desktop computer or your smartphone. More info: http://bit.ly/2m7FVIG

No
Note: Web client is delivered with vCenter - which is not included with this edition
vSphere 5 introduced a web based (Adobe Flex based) vSphere client interface which makes the access to vCenter platform-independent. The initial release was not a full replacement for the classic vSphere client app but with 5.1 it is considered the core management interface matching functionality to the (now) legacy client. It has a customizable interface and allows to view larger scale (i.e. multi vCenter) environments with a single inventory view (without using the old linked mode) through new single sign-on capability.

Adv. Operation Management
Details
|
No
There is no advanced operations management tool included with XenServer.
Additional Info:
XenServers Integration Suite Supplemental Pack allows inter-operation with Systems Center Operations Manager (SCOM). SCOM enables monitoring of host performance when installed on a XenServer host.
Both of these tools can be integrated with your XenServer pool by installing the Integration Suite Supplemental Pack on each of your XenServer hosts.
For virtual desktop environments Citrix EdgeSight is a performance and availability management solution for XenDesktop, XenApp and endpoint systems. EdgeSight monitors applications, devices, sessions, license usage, and the network in real time, allowing users to quickly analyze, resolve, and proactively prevent problems.
EdgeSight is actually discontinued and replaced by Citrix Director http://bit.ly/2lKLpaE

Updates and Backup |
|
|
|
Hypervisor Upgrades
Details
|
The XenCenter released with XenServer 7.0 allows updates to be applied to all versions of XenServer (commercial and free)
With XenServer 7.0 patching and updating via the XenCenter management console (enabling automated GUI driven patch application and upgrades) is supported with the comercial and free XenServer versions.
XenServer 6 introduced the Rolling Pool Upgrade Wizard. The Wizard simplifies upgrades to XenServer 6.x by performing pre-checks with a step-by-step process that blocks unsupported upgrades. You can choose between automated or semi-automated, where automated can use a network based XenServer update repository (which you have to create) while semi-automated requires local install media. There are still manual steps required for both approaches and no scheduling functionality or online repository is integrated.
Indroduced in Xenserver 7.1, live patching enables customers to install some Linux kernel and Xen hypervisor hotfixes without having to reboot the hosts. Such hotfixes will consist of both a live patch, which will be applied to the memory of the host, as well as a hotfix that updates the files on disk. This reduces maintenance costs and downtime. When applying an update using XenCenter, the Install Update wizard checks whether the hosts need to be rebooted after the update is applied and displays the result on the Prechecks page. This enables customers to know the post-update tasks well in advance and schedule the application of hotfixes accordingly.
XenServer Live Patching is available for XenServer Enterprise Edition customers, or those who have access to XenServer through their XenApp/XenDesktop entitlement.

Integrated Backup
Details

No (Retired)
Citrix retired the Virtual Machine Protection and Recovery (VMPR) in XenServer 6.2. VMPR was the method of backing up snapshots as Virtual Appliances.
Alternative backup products are available from Quadric Software, SEP, and Unitrends
Background:
With XenServer 6, VM Protection and Recovery (VMPR) became available for Advanced, Enterprise and Platinum Edition customers.
XenServer 5.6 SP1 introduced a basic XenCenter-based backup and restore facility, the VM Protection and Recovery (VMPR) which provides a simple backup and restore utility for your
critical vims. Regular scheduled snapshots are taken automatically and can be used to restore VMs in case of disaster. Scheduled snapshots can also be automatically archived to a remote CIFS or NFS share, providing an additional level of security.
Additionally the XenServer API allows for scripting of snapshots. You can also (manually or script) export and import virtual machines for backup purposes.
