1.2.1. Requirements to servers designed for server cluster operation

NOTE. To use 1C:Enterprise on a computer with an ARM64 or E2K processor, you need to have a CORP license.

Minimal requirements for production servers included in a 64-bit 1C:Enterprise server cluster:

Parameter	Value
Processor	x86-64 ARM64 (ARMv8 or later) E2K (E2Kv4 or later) Multiple cores or processors are recommended because they affect the 1C:Enterprise 8 server cluster throughput especially having many concurrent users.
RAM	Minimum: 4 GB or more Recommended: 8 GB or more
Storage	Hard drive or solid state drive. Installation requires at least 1 GB. The requirements do not include the database size.
Ports	USB port (for a dongle)
Linux	x86_64 processors: Astra Linux: Common Edition: version 2.12 Special Edition: version 1.6 CentOS: version 7 Debian: versions 10, 11 Mint: versions 19, 20, 21 Oracle Linux: versions 7, 8, 9 Red Hat Enterprise Linux (RHEL): versions 7, 8, 9 Ubuntu: versions 18.04 LTS, 20.04 LTS, 22.04 LTS ALT Linux: versions 8 SP, Education 9, Workstation 9, Workstation K 9, Server 9, Education 10, Workstation 10, Workstation K 10, Server 10. RED: version 7.3 ARM64 processors: Astra Linux: Special Edition: version 1.7 Ubuntu: versions 20.04 LTS, 22.04 LTS ALT Linux: Education 10, Workstation 10, Workstation K 10, Server 10 E2K processors: Linux Elbrus: 7.0, 7.1
macOS	x86_64 processors: Not supported ARM64 processors: Not supported E2K processors: Not supported
Windows	x86_64 processors: Windows: versions Vista Service Pack 2, 7 Service Pack 1, 8.0, 8.1, 10, 11 Windows Server: versions 2003, 2008 Service Pack 2, 2008 R2 Service Pack 1, 2012, 2012 R2, 2016, 2019, 2022 Ensure that the latest operating system updates are downloaded and installed. ARM64 processors: Not supported E2K processors: Not supported

1C:Enterprise supports several database management systems (DBMS). DBMS support depends on the computer's processor architecture. In the table below, the plus sign add indicates that a DBMS is supported on a computer with a processor architecture specified in the column header:

DBMS \ Processor architecture	x86-64	ARM64	E2K
IBM Db2	+
Microsoft SQL Server	+
Oracle Database	+	+
PostgreSQL	+	+	+

See general list of supported DBMS versions in Supported DBMS. If you have a 64-bit operating system, use 64-bit DBMS versions (if any).

Make sure that a computer running a DBMS server is in compliance with requirements applicable to any relevant DBMS version described in more detail in DBMS documentation. The bitness of DBMS server can differ from that of 1C:Enterprise server.
