ML350 gen9 with P440ar - can SAS expander card be used with this controller?

Hello,

 

We have the mL350 gen9 wiht P440ar on board controller (instead of the PCI-card version P440, P440ar = standard configuration in order to save an PCI slot). In a lot of documentation we read that it can be expanded with the SAS expander kit for ml350 gen9 769635-b21.

 

Then it should be possible to connect instead of 1 drivecage with 2 mini-sas cables, 3 drivecages with each 2 mini-sas cables to the SAS expander. The sas expander then should be connected via 2 mini-sas cables with the p440ar. By the way, in the manual for the SAS expander is mentioned that the kit does noet support the P440ar (but why, because of the fact that the right cables are not included or not supported hardware?)

 

In the kit there are 3 cable sets for the 3 drivecages, but not for the connection between the P440ar controller and the SAS expander. The original mini-sas cables from the P440ar to the original first drive cage are to short.

 

In some documentation i read that this kit doen not support the P440ar.

 

The question is: does it not support this because:

- the fitting cables are not included? (but with other cables this should work)

or

- this combination P440ar and SAS Expander is not supported by HP, no matter what cables are used

 

There is documentation where the SAS expander is shown connected to the P440ar and 3 drive cages in an ML350 gen9, so one would think it must be possible. It is however not supported by the kit, as stated in some documentation?

 

So is it a cable thing, or a harware incompatibility thing?

 

Thanks ahead, it is driving me nuts. HP US and NL do not have the answer. Our wholesale channels cannot answer this either. We don't want to assemble a config that is not supported.

Hi,

 

I would say its by design how these controllers are made.

Check the following document, page# 7 & 14

Re: ML350 gen9 with P440ar - can SAS expander card be used with this controller?

Dear ,

 

Thanks for the response.

 

All the document you mention, i found myself.

 

That however does not answer my question clearly:

 

Can the daughterboard controller P440ar in a ML350 gen9 be supported with a SAS expander card or not?

 

(Note: A P440 is a PCI controllercard and a P440ar is a daugterboard controller for the motherboard of a DL380 and a ML350, slightly different specs, same chipset).

 

Nobody can give me the answer: yes or no.

 

Thanks ahead,

Re: ML350 gen9 with P440ar - can SAS expander card be used with this controller?

Thanks!

 

Clear.

 

Although i think technically this perhaps should be able to work, HP supports in an ML350 Gen9 a normal p440 PCI-e card in combination with a SAS expander card, and not the P440ar daughterboard apparently.

 

Too bad for my preconfigured servers with P440ar, they were sold as upgradeable with SAS expander. They can, when you remove the P440ar en buy another P440. There goes our margin.

 

Again Thanks,

Hello @WvN

 

Suman_1978 has excellent information and is correct, the HP DL360 Gen9 Smart Array P440ar Controller (726740-B21) is not compatible with the HP ProLiant ML350 gen9.  The HP 12Gb SAS Expander Card is the SAS Expander (769635-B21) is compatible with the HP ProLiant ML350 gen9 server, which is available directly through the HP Small and Medium Business Store web site.

 

 

I hope this information is helpful.  Another option, I can connect you with an HP Server Specialist for more information or any other questions you may have.

I can't find anywhere in this thread that mentions the P440ar for a DL360 Gen9. There is a P440ar available for the ML350 Gen9

 

HP Smart Array P440ar/2GB FBWC 12Gb 2-ports Int FIO SAS Controller 749974-B21 is listed in the ML350 Gen9 Quickspecs.  The question at hand was is this card compatible with the SAS expander and apparently the answer is no, it is not.

Hello @Jimmy Vance

 

I do see that the HP DL360 Gen9 was not mentioned in the post, I got that from the HP web site, when I Googled Smart Array P440ar Controller and the one that pulled up was for the DL360 Gen9 and that was what I was trying to put across but I see that I was mistaken in saying there was not a P440ar available for the ML350 Gen9 and I do thank you for correcting that for me and I will know this in the future.

Looking at the cabling you should be able to get it working on 2 drivecages by connecting it to the p440ar using the SAS-cables meant for drivecage #3.

 

I don't get why it isn't supported, since those P440ar's and those expanders are both identical (at least the spare partnumbers are) in the DL380 and the ML350.
