Hardware requirements
|
IMPORTANT
The following system requirements are minimal. The target sizing should be calculated based on the customer requirements. |
ADB
-
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. |
The following are resources that are required on the host where ADB Control is installed.
| Service | CPU cores | RAM | Disk storage | Note |
|---|---|---|---|---|
Backend Server |
6 |
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. |
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 1 Gbps network to work. However, the recommended network performance is 10-25 Gbps and higher (the value depends on backup requirements).
