Query: Maximum RAM support HPE Proliant DL380 Gen10

[mohddlrd]

Hello and hope everything going well
 I just check HPE proliant DL380 Gen10 

some of CPUs 82XX,62XX,52xxL series support 4.5TB Memory 

so can we mix Intel optane 512GB on 12 DIMM slot with 256GB LRDIMM on 12 DIMM to other slot to get  9TB RAM ?

tnx

Hi,

I would suggest to first check the QuickSpecs regarding Optane support.

For details on the HPE Server Memory Options Population Rules, visit: http://www.hpe.com/docs/memory-population-rules

Thank You!
I work with HPE but opinions expressed here are mine.

Hello @ mohddlrd

Thank you for your post

we would suggest to check the  DL380 Gen10 quickspecs.

I checked this befor 
if you check you can see these cpu support 4.5 so DL380 Gen10 support 2 socket cpu so this server support 9TB Memory right?

Hello @ mohddlrd

-- Maximum memory per socket is dependent on processor selection. 2nd generation processors supporting 2 TB or 4.5 TB per CPU are indicated by the “M” and “L” in the processor model names (i.e. 8276M and 8276L). 1st generation processors supporting 1.5 TB per CPU are indicated by the “M” in the processor model names (i.e. 8160M)  

-- Maximum memory per socket is dependent on processor selection. Processors supporting 1.5 TB per CPU is indicated by the “M” in the processor model names (i.e. 8160M).  Mixing of RDIMM and LRDIMM memory is not supported. 

For General Server Memory and HPE NVDIMM Population Rules and Guidelines for Gen10 see details here: 
http://www.hpe.com/docs/memory-population-rules 

-- For second processor, please select the same processor model with –B21 from Core Options 
-– HPE Processors section. For example: first processor, select 874752-L21 then for second processor, select 874752-B21. 

Notes:   
-- Maximum memory capacity per processor is dependent on processor models. All processors support up to 768 GB max memory per processor except “M” model processors will support up to 1.5 TB max memory per processor. 
-- Mixing of 2 different processor models are NOT allowed. 
-- DDR4 speed is the maximum memory speed of the processor. Actual memory speed may depend on the quantity and type of DIMMs installed.

Notes:  
--  A maximum of 12 Intel Optane Persistent Memory for HPE supported with select 2nd Generation Intel Xeon Scalable Series Processors ONLY (82xx/62xx/52xx/4215R/4215) and can only be mixed with either RDIMMs or LRDIMMs.  
-- For configurations exceeding 1TB/socket, the “M” series (2TB/socket) or “L” series processors (4.5TB/socket) are required.   When mixing Intel Optane persistent memory with RDIMM, all RDIMM must be of same capacity and type. 
-- For information regarding Intel Optane Persistent Memory for HPE visit: http://www.hpe.com/info/persistentmemory

@Sham82 

Thank you for your explanation, so to summarize, we can have a total of 9 terabytes of RAM, correct؟

Hello @ mohddlrd

As mentioned in the quickspecs , "Maximum memory per socket is dependent on processor selection."
according to the processor installed , you can check the Maximum memory supported.
