Synergy SAS storage solution planning guidelines

When planning the installation of components in a frame, the following guidelines must be observed.
•
Select up to three D3940 Storage Modules per frame when installing a single HPE Synergy 12Gb
SAS Connection Module.
•
Select up to four D3940 Storage Modules per frame when installing dual HPE Synergy 12Gb SAS
Connection Modules.
•
One SAS I/O adapter is included with every D3940 Storage Module.
•
For redundancy and higher performance when using SAS drives, a second I/O adapter and
connection module must be added.
•
Any compute module connecting to a D3940 Storage Module must have a P542D Controller
populated in fabric 1, which is mezzanine slot 1 or 4.
•
If the D3940 Storage Module is configured with two SAS I/O adapters, a second SAS connection
module is required.
•
Each Synergy frame that contains at least one HPE Synergy D3940 Storage Module must also
contain at least one connection module.
•
There can be no more than two HPE Synergy 12Gb SAS Connection Modules in each frame.
