Battery\super-cap for Smart Array P441 on Gen8 server

[ENKON]

Because I had to get somethiung working NOW without waiting to order parts, I stole a P441 controller from a dl380 Gen9 and plugged it in to a DL360p gen8. Now that the immediate requirement for a server has been fulfilled, I need to get it working properly. It works no problem, but write cache is disabled because it has no battery. The issue is thjis gen 9 controller has a battery cable that plugs in to the mothyerboard riser and uses a shared battery. I need a new battery to use for the P440 in its new home in a gen8 server but the controller has a 3 pin connector that the battery cable pluggs in to and the only batteries I can find have cables with more than 3 pin connectors.

The simplest would be to find a battery that I can just plug in directly to the controller. Does anyone know of a 3 pin battery or super-capaciter that works directly with the P441 controller?

If there is no such thing assume I will have to buy a new controller that works with this DAS box and with a gen8 DL server such as a P421

Hi @ENKON 

The P440 controller requires a battery or super-capacitor connected via a 3-pin header to enable write cache. While the Gen9 P440 controller uses a shared battery connected to the motherboard riser, the Gen8 DL360p does not support this configuration. Therefore, you need to install a compatible battery or super-capacitor directly on the P440 controller.

Please have a look at the attached attached link, you might find it useful.

@Mamatha_J,

OK, based onh the parts surfer you linked:
"Smart Array P441 PCIe3 x8 SAS controller - External 2-port x4 mini-SAS HD connectors, 4GB of flashed back write cache (FBWC) memory, 12 Gb/sec transfer rate SAS, 6 Gb/sec transfer rate SATA - Does not include battery, FBWC cannot be ordered separately"

So, there is no campatibale battery to plug in directly yto the P441.

Unless someone has some personal experience with a battery that does work, I'll be buying a P421 with a 660091-001 HP FBWC Capacitor Pack

Hi,

The HPE Smart Array P441 and P440 Controller are HPE ProLiant Gen9 family of controllers.

Refer to the QuickSpecs
https://www.hpe.com/psnow/doc/c04346300

I would recommend acquiring a  Gen8-compatible controller like the P420 or P430 along with its compatible FBWC module and battery for DL360p Gen8 Server. This will ensure proper functionality, data integrity, and system stability.

Refer to the server QuickSpecs
