Hardware Requirements

[massimo_destito]

Good Morning,

I'm writing here for the first time and first of all I would thank everyone for the support I will receive

I need information about the correct hardware requirement of this ERP.

the bundle we have bought contains the following software

-SAP ERP 6.0 Production Ambient

-SAP ERP 6.0 Develop Ambient

-SAP ERP 6.0 Test Ambient

-SAP EMP1 For SAP NETWEAVER 7.3

-SAP SOLUTION MANAGER 7.1

And now we 'd like to know from an authoritative source the exact hardware requirements of the following machines to make the whole system more efficent

- Test ECC + Develop ECC

-Production ECC

-Soulution Manager

-SAP ROUTER

-PI TEST

-PI DEVELOP

-PI PRODUCTION

please consider the following details:

-The platform that is hosting all the system is a VMWARE Vsphere 4.1 U1

-All the machines except the saprouter will mount a Windows 2008 Server R2 x64

-The Database will be a MSSQL 2008 R2

-We are interested in a platform that should be capable to support just 60 users .

thanks in advance for the help

Hi,

As suggested above, is better to get the requirement with sap sizing. However, i can propose you a very brief, merely based on 60 users.

We have a client who run their SAP landscape on below hw requirements which supporting 50-60 users (not concurrent).

DEV & QAS:

Intel Xeon CPU, 4 physical CPU cores, 6GB for single stack, 8GB for dual stack.

PROD:

8 physical CPU cores, 8GB for single stack and 10GB for dual stack.

You can install saprouter together with solman or in any workstation, as it just run with few file and service.

Just my 2cents worth,

Cheers,

8 GB is very few for a production system.

We have 126 GB RAM for the production and no less than 36 GB for test and QA. However, this all depends how many users and what load you get on the system.

Hi Markus

how many users use 126Gb of RAM?

> how many users use 126Gb of RAM?

This is just DB + CI, users are working on 4 application servers.

We have about 1000 concurrent users and a bunch of external systems connected to that machine (CRM, SRM, legacy logistics systems). System is Unicode and 11 languages (including double byte languages) are productive.

Database is MaxDB (3,5 TB), OS is LInux (SLES 11 SP1).

The database server is running on bare metal, it doesn't make sense to virtualize such a big machine, the overhead would kill the performance (we tested).

So with 60 users and 10 GB of RAM should be ok

For a big system like ERP where you need rather big buffers I would not go below 16 GB.

keep in mind:

- operating system uses 1 - 1,5 GB (Windows 2008 R2)

- database usually uses half of the available memory, the bigger the database cache, the less physical I/O --> faster system

- you will need a rough 1,5 GB for just SAP buffers to keep the ABAP programs in memory

1,5 + 1,5 + 5 = 8 GB

That leaves 2 GB in total for all the 60 users which is available to actually work. That is not much. If one user executes a bigger list at some point your sytsem will start swapping.

For double stack systems it is even worse, the default Java heap on 64bit systems is 2 GB, plus dispatcher.

You can configure the systems smaller and just "as much as needed" but in case of e. g. an upgrade or a SP installation you may run into trouble. I would always calculate at least 25 % more than calculated necessary to leave some room.

Hi Markus,

In this scenario, 60 users (not concurrent) will using the system, therefore, we can just assign 2GB to MSSQL and it should work fine, and it works fine with our small customer environment.

For example, we have 8GB RAM.

2GB assign to MSSQL DB

1GB for OS

we still have 5GB for SAP Memory. From there, we can divide it to:

600MB to abap buffer, and <400MB to other SAP buffers.

4GB to phys_memsize --> shared memory allocate when needed.

Also, as SAP rules of thumb, 20% paging for physical memory is allowable and shouldn't deteriorate system performance.

As this is a simple system with small amount of user, i assume there's much customizing problem too.

Hi Nicholas,

I would like to request everyone to provide me the following Server hardware requirements for ECC, BI & BO Components

My company wants to install the ECC, BI & BO in the same box

So can you please provide me the Sample hardware requirements like how much

1. CPU

2. RAM

3. HDD

is required .

Thanx in advance.................................

This is very difficult to suggest you this way.

Choosing a particular 'hardware vendor' is also really a subjective matter and customer decision as well.

Better you start with SAP Sizing to understand the minimum requirement.

Thanks
