IMPORTANT

The following system requirements are minimal. The target sizing should be calculated based on the customer requirements.

ADB

  • Master host

  • Segment hosts

  • Physical server.

  • CPU: 8 cores or more.

  • RAM: 16 GB or more.

  • Disk storage: separate physical unformatted RAID 10 array (5 GB or more).

  • Physical server.

  • CPU: 16 cores or more.

  • RAM: 32 GB or more.

  • Disk storage: one or more physical unformatted RAID 10 arrays (10 GB or more per array).

ADB Control

NOTE

For more information on the ADB Control architecture, see Arenadata DB Control overview.

  • ADB Control host

  • ADB hosts

The following are resources that are required on the host where ADB Control is installed.

Service CPU cores RAM Disk storage Note

Backend Server

16 GB

 — 

Requires additional monitoring of inner metrics queues

Scheduler

2

4 GB

 — 

Resources consumption may depend on the jobs configuration (like time periods, batch sizes, scheduling of heavy jobs to run at the same time)

Metrics DB (ClickHouse)

4

16 GB

100 GB

It is better to have the RAM amount that is equal to the compressed data in ClickHouse

Query DB (PostgreSQL)

4

8 GB

200 GB

Storage should be managed carefully so that it won’t be exhausted between data cleanup events in ADB Control

Other components: PlanChecker, Web UI & UI Backend Server, Service Registry

The following are resources that are required on each host of ADB cluster where ADB Control agent is installed:

  • CPU: 4 cores or more.

  • RAM: 4 GB or more.

ADBM

NOTE

For more information on the ADBM architecture, see Arenadata DB Backup Manager overview.

  • ADBM host

  • ADB hosts

Arenadata DB Backup Manager can be installed on the same host as ADB Control or on a separate host. ADBM host requires the following minimal resources (for etcd, Backup Manager, Service Registry):

  • CPU: 4 cores or more.

  • RAM: 12 GB or more.

  • Disk storage: 10 GB or more.

On segment hosts, 30% CPU and 2 GB RAM are utilized by ADBM agent and pgBackRest instance for a one-threaded backup process.

ADBM agents on segment hosts require not less than 25 Gbps network to work.
