R650 PERC front load vs rear load

Hello,

For the part number question; the second part number identifies front or rear load:

750-ACFR is for PERC H755 Front Load

750-ACFQ is for PERC H755 Rear Load

Regarding the "rear load" and "front load" terminologies, they refer to the physical placement and accessibility of the PERC H755 controller within the server chassis:

Rear Load PERC H755: In this configuration, the PERC H755 RAID controller is installed in a rear expansion slot of the server chassis. This placement allows for easy access to the controller from the rear of the server, typically through a removable panel or cover. Rear load configurations are common in rack-mounted servers where the rear of the server is easily accessible.

Front Load PERC H755: In this configuration, the PERC H755 RAID controller is installed in a front expansion slot of the server chassis. This placement allows for easy access to the controller from the front of the server, typically through a removable panel or bezel. Front load configurations are common in tower servers or servers where the front of the server is easily accessible.

In terms of functionality, there is no difference between the rear load and front load versions of the PERC H755 RAID controller. The difference lies in the physical placement and accessibility of the controller within the server chassis.

When selecting a PERC H755 RAID controller, you should choose the version that is compatible with your server chassis and meets your accessibility requirements based on the server's configuration and deployment environment.
