Re: ESXi 6 + HP Proliant DL 380 Gen9 = 49GB ram in...

aleber76 · ‎04-01-2015

Hi everyone

I just installed a brand new HP Proliant DL 380 gen9 with ESXi 6 customized ISO image.

There are 64GB ram installed in the system. The RAM is correctly enumerated at the bios startup, and from the ILO console there are no errors.

Despite of this, the total RAM available in ESXi in 49GB!!! There are almost 16GB missing, ad it seems that ESXi cannot see this amount of ram.

Have you ever experienced this issue?

Thanks

Alessandro

Please post the output of the following ESXi shell commands:

# esxcli hardware memory get

# esxcli hardware cpu global get

# enum_instances OMC_PhysicalMemory root/cimv2

That's indeed odd, what happens when you boot the host into a Linux live CD?

The only case I would expect something like this is a spare memory redundancy configuration or some similar odd BIOS configuration, have you checked that or reverted the BIOS to factory default?

Querying some other HP provider classes might be helpful too:

# enum_instances SMX_Memory root/hpq

# enum_instances SMX_MemoryModule root/hpq

# enum_instances SMX_MemoryRedundancySet root/hpq

(Some more interesting memory related CIM classes can be found in this document from page 584 http://h20565.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03250841-3&docLocale=&ei=4eQbVYKAF8S...)

I agree, it's really odd...

Also the other queries you suggested gave me the same result: there are 64GB installed, no doubt.

Look at this i.e.:

SMX_MemoryRedundancySet.InstanceID="HPQ:SMX_MemoryRedundancySet:001"

InstanceID = HPQ:SMX_MemoryRedundancySet:001

OtherLoadBalanceAlgorithm = (NULL)

LoadBalanceAlgorithm = 2

OtherTypeOfSet = { Advanced ECC, }

VendorIdentifyingInfo = (NULL)

MaxNumberSupported = (NULL)

MinNumberNeeded = (NULL)

TypeOfSet = { 1, }

RedundancyStatus = 2

Caption = Memory Redundancy Set

Description = Memory Redundancy Set for Advanced Memory Protection

ElementName = Memory Redundancy Set

ConfigurationsAvailable = { Advanced ECC, Online Spare Rank, Mirroring Intra Socket, }

TargetConfiguration = Advanced ECC

CurrentConfiguration = Advanced ECC

OperatingSpeed = 2133

AvailableMemory = 65536

TotalMemory = 65536

OperatingVoltage = 1200

TargetConfigurations = { Advanced ECC, }

CurrentConfigurations = { Advanced ECC, }

....

Unfortunately I cannot try a live cd now, it's already a production server. For sure i'll try to reboot it during night-time

All

ESXi 6 + HP Proliant DL 380 Gen9 = 49GB ram instead of 64GB!!!
