Redis versions and configurations
Versions
Redis versions 6 and 8 are supported.
Node configurations
When creating a Redis Managed Database cluster, you can select the node configuration—the number of vCPUs, RAM, and disk size.
Available node configurations are divided into lines. Depending on the line, configuration, and pool, different processors and volumes are used.
When selecting a configuration, keep in mind that some disk space is reserved for service needs and is unavailable for database placement. Learn more in the instructions Using disk space in a Redis cluster.
After creating a cluster, you can change the node configuration by scaling the cluster.
Configuration lines
In all configuration lines, the resource ratio is fixed.
To see the availability of configurations in the regions, see the Managed Databases availability matrix.
Standard
A line of fixed configurations with a local disk and a balanced vCPU:RAM ratio, suitable for most DBMS. We recommend using this line if you do not know the load profile.
Intel® Xeon® Scalable or AMD EPYC™ processors are used. You can view processor frequencies for different lines in the Processors table.
To view disk performance and bandwidth for different lines, see the Performance and bandwidth table.
HighFreq
A line of fixed configurations with a balanced vCPU:RAM ratio.
High-performance Enterprise-grade hardware is used:
- Intel® Xeon® Gold 6354 processors (in pools ru-9, ru-2, ru-8, ke-1) or AMD EPYC 9474F (in pools ru-3, ru-7, uz-1). You can view processor frequencies for different lines in the Processors table;
- RAM 3.2 GHz ECC Reg (in pools ru-9, ru-2, ru-8, ke-1) or RAM 4.8 GHz DDR5 ECC Reg (in pools ru-3, ru-7, uz-1);
- High-performance SSD NVMe disks. To view disk performance and bandwidth for different lines, see the Performance and bandwidth table.
Dedicated
A line of fixed configurations with cluster nodes on separate cloud servers. Each cloud server occupies an entire dedicated host (physical server). This is suitable for users who require physical database isolation from other clients, maximum performance, and maximum available resource sizes.
High-performance Enterprise-grade hardware is used:
- one Intel® Xeon® Gold 6336Y, Intel® Xeon® Gold 6240, Intel® Xeon® W-2255, or Intel® Xeon® E-2488 processor, depending on the configuration. You can view processor types and frequencies for different lines in the Processors;
- 128 GB DDR4 ECC Reg RAM, 64 GB DDR4 ECC Reg RAM, or 32 GB DDR5 ECC Reg RAM, depending on the configuration;
- SSD NVMe drives in RAID 1. The number of drives in a cluster depends on the configuration. You can view drive performance and bandwidth for different lines in the Performance and Bandwidth;
- two 2 × 25 GE network cards for the primary network + MC-LAG with a 25 Gbit/s connection speed for the service network (for backup, monitoring, and intra-cluster data replication).
* DBMS clusters use Hyper-Threading Technology. Each physical core can process multiple threads in parallel — this allows the total number of virtual cores (vCPU) to exceed the number of physical cores. This enables more efficient load distribution for multithreaded or analytical tasks.
** Part of the RAM is reserved for physical server service processes.
* ** Volumes are combined into a RAID 1 mirrored array that provides additional fault tolerance. When using mirroring, 50% of the total disk space is available for databases. Part of the disk space is also reserved for physical server services.
Processors
Available processors differ between fixed and custom configuration lines. Processor frequency affects the speed of processing user requests, executing complex algorithms, and performing data operations. When a cloud server load reaches 100%, the processor runs using Turbo Boost technology. Since the processor is virtualized, a lower frequency will be displayed during testing.
