Typical Hardware and Virtual Machine Configurations for PCS and PCP Licenses

When your organization purchases a Private Cloud Subscription (PCS) or Private Cloud Perpetual (PCP) license for MYOB Acumatica, your purchase manager selects a License Tier, which limits the parameters that influence system performance. The License Tiers are grouped into the following series:

• S Series: Includes the S1, S2, and S3 Tiers
• M Series: Includes the M1, M2, and M3 Tiers
• L Series: Includes the L1, L2, L3, and L4 Tiers
• X Series: Includes the X1, X2, X3, and X4 Tiers
• E Series: Includes the E1, E2, E3, E4, and E5 Tiers

This topic contains typical server configurations for PCS and PCP licenses that depend on the series of your License Tier, the software requirements for the server part of the system, and the system requirements for workstations.

Server Configurations

This section describes the typical hardware specifications for the servers used to host MYOB Acumatica (which includes the application server and the database) and the typical configurations of Amazon Web Services and Microsoft Azure instances for each series of License Tiers.

You should install the application server and the database on separate virtual machines or physical servers. In the following subsections, you can find typical specifications for each of these configurations.

When you install MYOB Acumatica on virtual machines, you should consider the following:

• You should install the application server and the database on separate virtual machines.
• You should allocate these virtual machines for MYOB Acumatica only. (No other software should be installed there, including antivirus software.)
• Virtual machines decrease hardware performance by approximately 15%. For maximum performance, you could eliminate VMs and run directly on the node operating system; however, you will lose the benefits and flexibility of VMs. Most clients choose VMs for this reason.
• You should not use dynamic memory for virtual machines. You need to allocate the required RAM capacity for each virtual machine.
• Each virtual machine should use a separate physical hard drive. That is, you should not share one physical hard drive between multiple virtual machines.
• If you use hard drives with a low writing speed, then increasing RAM will not improve the database performance. We recommend that you use hard drives with a high writing speed for the database server.
  Note: You should not use the RAID 5 level for hard drives because of the low writing speed.

When you install MYOB Acumatica on separate physical servers, you should consider the following recommendations:

• You should install the application server and the database on separate servers.
• You should allocate these servers for MYOB Acumatica only. (No other software should be installed there, including antivirus software.)
• Network latency between an application server and a database should be less than 1 millisecond. (Both servers should be in the same data center.)
• If you use hard drives with a low writing speed, then increasing RAM will not improve the database performance. We recommend that you use hard drives with a high writing speed for the database server.
  Note: You should not use the RAID 5 level for hard drives because of the low writing speed.

* The number of CPUs and RAM size are defined by the instance type; these parameters are provided in the table for reference.

**The IOPS parameter for a hard drive of the gp2 type is calculated automatically by AWS according to the hard drive size.

When you deploy Acumatica ERP in AWS, you should consider the following:

• All AWS instances should be EBS-optimized.
• If you want to increase the speed of storage, you need to select the higher network performance between the Database Server VM and the Application Server VM.

* The number of CPUs and RAM size are defined by the instance type; these parameters are provided in the table for reference.

Software Requirements for the Server Part

The environment where you install the server part (the Application Server and the Database Server) of MYOB Acumatica should meet the software requirements listed in the table below.
