Since they have more than 30 users, so that C: drive is full now.

Hi Edmund,

B1 is a database driven application. As such, hardware and Windows settings should be favorable for a database. Please have a look at this blog for some tips for your hardware setup. The same blog also has some information about storage.

The amount of storage needed depends on several factors:

  1. the number of transactions you have already created (for example: 1 sales order with 5 line items = 6 transactions, the sales order results in a full delivery = another 6 transactions, when you invoice the delivery you add another 6 transactions. If you have to create a credit memo for this invoice you add another 6 transactions. Total 18 - 24 transactions If you have to first purchase the necessary stock, you could be creating the same number of transactions on the purchase side, etc.).
  2. the estimated amount of transactions you will be making over the given 5 years.
  3. to a lesser degree the amount of user defined fields you have added already and new ones you will add over the given 5 years, with changes in your business scenario.
  4. will you be adding a lot of attachments (powerpoint, excel, and word documents, etc) that will get saved to the same server?
  5. will you be saving item images?
  6. will you be running other software on the same server?
  7. will the server perform other roles (domain controller, file server, print server, etc)?
  8. will you be using B1's archiving functionality?

As you can see, it will be hard for any tool to calculate the needed storage capacity for you. However, you could quickly create your own calculation tool with Excel. A single transaction is (very) roughly 0.002 MB in size. Multiply that number by the number of transactions that you estimate you will have after 5 years, and add to that the estimated total size in MB of any attachments and images. Multiply the total by at least two (see the blog).

Regards,

Johan

Dear Johan

Thanks for your information.

In my case, C:drive is used to install the application, but why it is full, because it assign 40GB for it.

Since the server has already created more than 30 users, if they would like to create more users account, they cannot do that, it is because the hard disk size is full.

Someone find this image to me. But I can't find the most updated one from SAP portal or other link.

For the concurrent users 30, I should have 150 GB, but now, the Window profile may use 1 GB per user. After I install the SQL server and B1, it may already have 40GB, it cannot install other software and I may only have 1 window profile.

So how many should I have?

Edmund

Hi Edmund,

In my blog post there is a paragraph about hard disks, and a paragraph about Remote Desktop users. If these paragraphs and my answer don't answer your question, I am afraid that I have misunderstood your question.

Could you please rephrase your question one more time?

Regards,

Johan

Hi,

Check log files each of database in C-drive. Change Recovery model from FULL to Simple for each database if you MSSQL Server installed in C-drive.

Hi Edmund,

Other than Johan's blog, there is a Hardware Requirements Guide for the B1 family on the SAP Help Portal. You will need the S number to access: https://help.sap.com/http.svc/rc/011000358700000244612011e/9.3/en-US/B1_Hardware_Requirements_Guide.pdf - don't know why the comment box doesn't recognize this link as a valid url. You may need to copy and paste it in your browser.

Personally I am not quite familiar about the tech specifications. The performance issues I've seen are most of time because of RAM resource other than hard disk space. Regarding your scenario, do you have the Windows OS, B1 application and SQL Server installed in the same C: drive? Sometimes the Windows profiles and some system files eat up a lot of space in my C: drive. You may need to check the system files, also check your database size too.

Thanks,

Jimmy

Dear Jimmy

The above link show like this 'We're sorry, but this content is not accessible.'

I would like to know, the B1 and SQL Server application, normally, I will install on C: drive.

The data and backup, I will save in D drive.

As you said, the window profiles and some system files eat up a lot of space.

So that 40GB, is enough for window profiles and some system files?

In my notebook, 120GB, often full.

So that, SAP B1 Hardware Requirements Guide should consider the size with B1 and SQL Server, also window profiles/ number of users in server. I have an Excel which only calculate the RAM and CPU for physical and VM server.

It didn't mention hard disk.

Hi Edmund,

I would like to share the following:

1. Most of the clients I have worked with have separate servers or VMs for their systems (B1 application server, database server, and some will use additional server to run other B1 components, such as terminal server, and reporting server). I see that the DBs are in a different drive as mentioned, but I will concern about the HD space because B1, SQL and the Windows OS are all competing that 40G in C: drive.

2. The link I shared requires the S number (something like "S0123456789") to access. You can access to other B1 official documentation and user guides on the SAP Help Portal.

3. I don't think I should share the whole file here, but it seemed to me that the chart you referred to in one of your posts might not be for B1. Below is a screenshot from the "B1 Hardware Requirements Guide", please note this is only the minimum requirement for the application server.

And according to this document, "The requirements listed in this document apply to SAP Business One software in general, and are independent of any underlying database, Microsoft SQL Server or SAP HANA." This means to me only the B1 application itself may take over 20 G of space. I wonder if the Window OS and SQL will be happy sharing the rest 20 G in the same C: drive.

Hope this helps.

Regards,

Jimmy

Dear All

Another team assign 40G hard disk for me, and they did not tell me and expect me to install B1 and SQL server in E drive.

Do any one know browser access will be growth by number of users?

I remember that it seems require 500M per user.

Regards

Edmund
