HP Proliant DL760 G2 Linux Architecture

[Paul J Harding]

I have a quad-cpu, dual core Intel(R) Xeon(TM) MP CPU 2.70GHz setup.

I am trying to figure out if I should use

Redhat Enterprise AMD64
Redhat Enterprise EM64
Redhat Enterprise IA64
or
Redhat Enterprise x86-64

Can someone shine some light for me on this?

hi paul

is your server DL750 G2?

has the processor any processor number?

Well, there's nothing called a DL750G2, so I'm not sure what model you are talking about.

IA-64 refers to a Itanium processor, which is not available in the ProLiant line; it is available in the Integrity line.

You will find that there is a single Red Hat Enterprise distribution for x86_64. There are subtle differences between the AMD64 and Intel EM64T architectures, but the x86_64 installer will detect and select the appropriate kernel for your installation.

[Paul J Harding]

Thanks for the advice..

I mis-typed my model... its DL760 G2.

I will look into getting the x86-64, as my installation package only includes install cd's
for x86-32bit and AMD64/EM64

I am not sure how I can find my processor number, I will probably end up having to go to the data center and open it up, or atleast check the BIOS.. is there a way to display the model # in linux? /proc/cpuinfo isn't showing me much.

[Paul J Harding]

Karlo,

That Intel link was useful. My CPU cache is 2mb and i know it's an MP, so my chips are either the 7040 or 7041.

The chip supports Hyperthreading & says 'yes' for Intel 64.

[David Claypool]

Whoa, there, Paul, the DL760 G2 pre-dated any of the multi-core processors. If you are showing 8 processors, then you have 8 distinct processors. If you are seeing 8 processors reflected in something like Windows Task Manager, you possibly have 4 sockets populated and HyperThreading enabled.

Regardless, this model pre-dates Intel EM64T so you should use x86-32 versions of the operating system.

The dmidecode command can give you all sorts of detailed information about the versions of your hardware and BIOS.

With a proliant you can also look at the system configuration with ILO and System Insight Manager tools.

[Paul J Harding]

The 8 cpu's show up in /proc/cpuinfo .
It could very well be 4 cpu's hyperthreaded.
but my dmidecode goes up to 8

I checked dmidecode and does it fact give me an MP Processor as well as 8 Socket Destinations:

Handle 0x0400
DMI type 4, 32 bytes.
Processor Information
Socket Designation: Proc 1
Type: Central Processor
Family: Xeon MP
Manufacturer: Intel
ID: 26 0F 00 00 FF FB EB BF
Signature: Type 0, Family F, Model 2, Stepping 6
Flags:
Version: Not Specified
Voltage: 2.8 V
External Clock: 100 MHz
Max Speed: 3000 MHz

Status: Populated, Enabled
Upgrade: Slot 2
L1 Cache Handle: 0x0710
L2 Cache Handle: 0x0720
L3 Cache Handle: 0x0728

-----

Some other interesting info.. below the
Processors in dmidecode is the Internal L1 Cache. 4 of them are enabled.. 4 are disabled. Here's an enabled one

Handle 0x0710
DMI type 7, 19 bytes.
Cache Information
Socket Designation: Internal L1 Cache
Configuration: Enabled, Not Socketed, Level 1
Operational Mode: Unknown

Error Correction Type: Unknown
System Type: Unknown
Associativity: Fully Associative

The same goes for L2 & L3 cache.. 4 enabled 4 disabled

---

Is this still considered 32-bit?

[Paul J Harding]

There is definitely only 4 cpus...
but they definitely are MP's
