Overview of the Patch and Update framework
The Dell Hybrid Cloud System for Microsoft includes the Patch and Update (P&U) framework. This framework enables
you to easily update the infrastructure components of the Dell Hybrid Cloud System for Microsoft stamp with minimal or
no disruption to tenant workloads. The framework automates the installation of software, driver, and firmware updates
on the physical hosts and the infrastructure VMs.
Note: The P&U framework does not update tenant VMs.
When the P&U framework runs, it does the following:
• Orchestrates the updates so that they are performed in the correct order.
• Automatically puts servers in and out of maintenance mode during servicing.
• Validates components when servicing is complete.
The P&U framework installs approved software updates on infrastructure hosts and VMs for various
combinations of the following products:
Note: Any given package may or may not contain updates from all the categories listed. For the specific contents of
any particular package, see the package Release Notes, which you can obtain from the same download location as
the package itself.
• Windows Server
• Windows Azure Pack
• System Center
• SQL Server
• Dell software
• Dell Deployment UI
• Drivers and firmware updates for Dell Hardware.
If the package also includes firmware and driver updates, the framework installs the approved firmware and driver
updates on the physical cluster nodes.
IMPORTANT: Do NOT install Windows Server, Windows Azure Pack, System Center, and SQL Server updates by
using any method other than the P&U framework. Install only update packages that Microsoft and Dell have tested
and approved for the Dell Hybrid Cloud System for Microsoft.
