A customer is considering the DL380 Gen9 as the platform standard for its VLAN cluster. The configuration will
use 24 drives. Each 8-drive cage will contain 1 SSD and 7 SATA drives.
Which array controller should the architect recommend for this configuration?

A.
HPE Dynamic Smart Array B140i controller

B.
HPE Smart Array P840 controller

C.
HPE SAS Expander

D.
HPE Flexible Smart Array P440ar controller

Explanation:

HPE Flexible Smart Array P440ar controller has 8 Internal SAS/SATA physical links across 2 x4 ports.
The controller supports the HPE SmartCache feature, which is a controller-based read and write caching solution in a DAS environment that caches the most frequently accessed data (“hot” data) onto lower latency
SSDs to dynamically accelerate application workloads. The HPE SmartCache architecture is flexible and supports any HPE ProLiant Gen9 supported HDD for bulk storage and any HPE ProLiant Gen9 supported SSD
as an accelerator.
