Your customer plans to deploy VMware vSAN using D3940 Storage Modules. Which statement about this solution is true?

The HPE Synergy D3940 Storage Module connects to Synergy Compute Modules via an HPE Smart Array P408i-s SR Gen10 Controller. This specific type-s controller is cabled directly to the compute module's system board. The PCIe lanes required for this controller's operation are managed by the second processor socket. Therefore, for the system to recognize and utilize the P408i-s controller and its attached D3940 storage, a second CPU must be physically installed in the compute module. This is a hardware-level architectural requirement for this specific storage configuration.

A. The Synergy 12Gb SAS Connection Modules can be installed in multiple fabrics for redundancy and connectivity, typically in bays corresponding to Fabric 1 and Fabric 2, not exclusively the first fabric.

C. VMware vSAN supports both all-flash (all SSDs) and hybrid (SSD cache tier and HDD capacity tier) configurations. A deployment on D3940 modules does not mandate an all-SSD architecture.

D. VMware vSAN requires the storage controller to be in HBA (pass-through) mode, presenting individual raw disks to the hypervisor. Configuring a hardware RAID logical drive is contrary to vSAN's design.

1. HPE Synergy 480 Gen10 Compute Module QuickSpecs. In the "Storage Controllers" section

under the description for the "HPE Smart Array P408i-s SR Gen10 Controller

" Note 1 states: "The P408i-s is a Type-s Smart Array controller that is required for connectivity to the D3940. This controller is cabled to the system board and requires a second processor to be installed." (Document ID: a00008151enw

Page 12).

2. HPE Reference Configuration for VMware vSAN on HPE Synergy. This document explicitly details the controller mode requirement for vSAN. In the "Storage controller configuration" section

it states: "The HPE Smart Array controller must be configured in HBA mode." It also provides examples of both hybrid and all-flash vSAN configurations using D3940 modules

invalidating the all-SSD claim. (Document ID: a00050309enw

3. HPE Synergy 12Gb SAS Connection Module QuickSpecs. The "Configuration Information" section details installation rules

showing the module can be installed in Interconnect Bays 1

and 5

which correspond to multiple fabrics

disproving the restriction to only the first fabric. (Document ID: 826322-b21
