Dell POWEREDGE R720 - Manual (Page 33)

Update Dell™ Server Hardware with Dell OpenManage Essentials
33
These are the recommendations for using the patch feature, based on the analysis of the test results:
1. Recommendation is to update not more than 30 managed systems at any given time.
2. Dell SUU is recommended as the catalog source for system update as the packages are
downloaded at a faster rate.
3. Separate system update tasks must be created for Windows and Linux targets in case of Inband
system updates.
