TPM on S5500WB

idata — Mon, 07 Mar 2011 12:50:43 GMT

Hello,

I would to know if SR1695WB that has S5500WB board, has TPM. It seems that not all the board have it:

http://www.intel.com/support/motherboards/server/sb/CS-031481.htm?wapkw=(SR1600UR+tpm) http://www.intel.com/support/motherboards/server/sb/CS-031481.htm?wapkw=(SR1600UR+tpm)

If yes I would understand if TPM drivers are available on Linux environment further than Windows (on driver download page I found only Windows driver).

Thank you

Daisy

No S5500WB doesn't support TPM. TPM is only supported on S5520HCT, S5520URT (the last T means TPM support) and S5520SC.

S5500WB does not contain a TPM.

These do however.

I am not a Lunux person, and believe that TPM is primarly a windows feature, but the last generation of TPM products, the Linux driver was embedded.

Thank you Doc and Edward.

The problem is that we need a DC server and it seems that none of the server that support a TPM motherboard has a DC power supply.

Thank you also about linux information unfortunately the S5000XVN is no more available.

So..I think I havn't a solution..or do you know if it is possible put on the S5500WB board a third part TPM? I'm not an expert about TPM so I really don't know if is possible add an external component and if the board need to have specific features to support it...

Obviously I don't find anything about in the supported hw list!

Thank you

Daisy

When TPM's first were released there were a few available as add in cards, but I don't know of any that are still made that way.

(as a security feature, something removable or swapable between systems kind of defeats the purpose of a hardware encryption lock.)

When you say you need a DC server. are you looking for something like a 48v DC input power? (common in Telco environment)

There are a number of vendors who make this type of power supply in a standard SSI ATX form factor that would fit in most pedestal chassis although I don't know of any that have been tested with HCt or URt servers.

I did a quick web search and found sitees with 48v supplies. http://www.powerstream.com/48-volt.htm http://www.powerstream.com/48-volt.htm

The 48v input would then be converted to the standard SSI computer power supply outputs to run the mother board and peripherals.

The WB system use 12v (& 5v Standby) which allows for some great power effecencies, but no TPM (or TXT) support.

(If you want to buy enought of them, maybe your Intel sales rep can get it added?)

Yes -48 V power supply.

Ok thank you to all, it's clear.
