Overview
APEX Private Cloud and APEX Hybrid Cloud allow expansion of a subscription by adding more instance block groups to an existing cluster or by adding new clusters. The APEX Configuration sizer tool will assist in calculating a recommended capacity expansion. APEX instance sizing is also now supported in the VxRail Sizing Tool.
Expand your APEX Private Cloud on-premises cluster capacity by adding extra clusters to your subscriptions from the APEX console with the required number of instances and storage.
With APEX Hybrid Cloud, use the APEX console to add management block groups or add extra clusters to your subscription with the required number of instances and storage. Flexible options are available for data storage with independent scaling of resources.
- Connect and utilize existing vSAN with HCI Mesh,
- Connect with APEX Data Storage Services or Dell storage arrays such as PowerFlex, PowerStore-T, PowerMax, or Unity XT.
- Refresh or transition infrastructure at your pace for different procurement cycles.
This Dell Technologies Validated Design for VDI uses MCS linked clones, as shown in the following figures.
A Citrix "pod architecture" consists of a virtual desktop "site" and one or more "zones" at each site. The maximum limit when using Citrix pod architecture with the LHC feature enabled is 10,000 VDAs per zone and 40,000 VDAs per site.
A reasonable limit to choose is 5,000 linked-clone VMs per zone. With this limit, 25 compute nodes with 200 task-user VMs per node would reach the maximum number of VMs for the zone. The following figure shows a 5,000-user MCS linked clone/vSAN configuration, which equates to a single zone within a site:
The following figure shows a scale-out of 20,000 MCS linked-clone VMs with vSAN. The recommended limit for a zone is 10,000 sessions. In this example, there are two sites with three zones each. The sites are load-balanced and presented to the users as a single entity
