Administrator Guide
However, if a signicant amount of time has passed between the original order and the expansion, it is likely that image versions and/or
rmware versions may be dierent. Before beginning the expansion deployment, it will then be necessary to bring the existing environment
up to a solution release level that is compatible with the images provided on the expansion chassis. The Patch and Update (P&U) process
can be used to update the solution stack.
For more information about P&U, go to support.dell.com>Servers, Storage and Networking >Engineered Solutions >Dell Hybrid Cloud
System for Microsoft. P&U packages and documentation will be released to that site when available.
NOTE: Because they require imaging before they are delivered, compute nodes and backup nodes are shipped from the Dell
Integration Centers. All other components ship directly to the customer without any customization.
Physical installation
Install the compute chassis into the rack unit above the upper-most chassis that is currently deployed in the solution. Run the power cables
from the chassis to the PDU, and connect the 10GbE ports on each C6320 server to the appropriate ports on the Dell Networking S4048-
ON switches.
Deploying compute expansion nodes
The Deployment user interface remains installed on the console VM (<prex>CON01) and is used to start the DeployDriver for compute
expansion. Consult with your Dell technical support representative to nd out how to deploy compute expansion nodes for your
implementation of the Dell Hybrid Cloud System for Microsoft.
NOTE
: Compute expansion is implemented by Dell Services.
Adding another server to backup infrastructure
You can add DPM backup servers to an existing Dell Hybrid Cloud System for Microsoft backup infrastructure. Deployment of the backup
servers is implemented by Dell Services. You can expand up to three backup servers.
After you run the BackupDeployDriver script, run the Complete-BackupDeployment runbook. You do not have to run the Protect-
ManagementComponents runbook.
Then, you may have to run P&U to ensure that the latest updates are applied, and that the stamp and backup infrastructure are at the
same version.
Use the following guidance to determine if and when a P&U run is required.
Table 40. Conditions for P&U run
Conditions P&U run required?
Stamp is at same version as the new backup host. A P&U run is not required after you add the backup host.
Stamp has a later version than the new backup host. Run a required P&U after you add the backup host.
New backup host has a later version than the stamp. Before you add the backup host, run a required P&U to update the
stamp to the same version as the new host.
To check the Microsoft update version on a new node, open the
le C:\Program Files\Microsoft Cloud Solutions\Version.xml on the host.
To check the Microsoft update version on the stamp, see How to check which update package is installed.
