Before deploying SAP Business One, you need to plan required resources.

Table 1 lists the operating system requirements of the SAP Business One node.

**Table 1** Operating system requirements
Item	Specifications
OS	SAP B1 9.3: SUSE Linux Enterprise Server for SAP 12

Table 2 describes the disk plan for the SAP Business One node.

**Table 2** Disk planning
Disk	Type	Sharing Mode	Size
OS disk	High I/O	Non-shared disk	N/A
Log disk	Ultra-high I/O	Non-shared disk	When the memory size is less than or equal to 512 GB, the log disk capacity is half of the memory size and rounded up for decimal places. When the memory size is greater than 512 GB, the log disk capacity is 512 GB.
Data disk	Ultra-high I/O	Non-shared disk	The capacity is the same as the memory size.
Shared disk	High I/O	Non-shared disk	The capacity is the same as the memory size.
Backup disk	N/A	Provided by SFS	The recommended capacity is three times or more of the memory size.
/usr/sap disk	High I/O	Non-shared disk	50 GB
Swap disk	High I/O	Non-shared disk	10 GB

Table 3 describes the deployment requirements of the SAP Business One Client node.

**Table 3** SAP Business One Client node planning
Node	Requirements
SAP Business One Client	Operating system: Windows Server 2012 ECS Specifications: c3.large.2 (2 vCPUs, 4 GB memory) or larger Disk: 80 GB system disk

NOTE:

SAS hard disks have high I/O while SSD hard disks have ultra-high I/O.

Figure 1 shows the network plan for the single node scenario.

NOTE:

The network segments and IP addresses are for reference only.

Figure 1 Network planning in the single node scenario

In this scenario, only one NIC is used for network communication.

Table 4 shows the planned network information.

**Table 4** Network planning in the single node scenario where HA is not required
Parameter	Description	Example Value
IP address of the server/client plane	The SAP Business One node communicates with the SAP Business One Client software using this IP address. The SAP HANA node communicates with service software or SAP HANA Studio client software using this IP address.	SAP Business One: 10.0.3.3 SAP Business One Client: 10.0.2.2
EIP	Users access SAP Business One Client using EIP (public IP address).	Automatically allocated

NOTE:

The network segments and IP addresses are for reference only. The following security group rules are recommended practices. You can configure your own security group rules as needed.
In the following table, ## stands for the SAP HANA instance ID, such as 00. Ensure that this ID is the same as the instance ID specified when you install the SAP HANA software.
For more information about specific ports and security group rules to be accessed by SAP, see SAP Help Portal.

**Table 5** Security group rules (SAP Business One)
Source/Destination	Protocol	Port Range	Description
Inbound
10.0.2.0/24	TCP	139	Port used for obtaining files during application installation
10.0.2.0/24	TCP	3##15	Ports for the service plane
10.0.2.0/24	TCP	4##00	Ports for the service plane
10.0.2.0/24	TCP	5##00	Ports for the service plane
Automatically specified by the system	All	All	Security group rule created by the system by default Allows ECSs in the same security group to communicate with each other.
Outbound
All	All	All	Security group rule created by the system by default Allows SAP HANA to access all peers.
