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.
The available node configurations are divided into lines. Depending on the line, configuration, and pool, different processors and disks are used.
When choosing a configuration, keep in mind that a portion of the disk space is reserved for service needs and is unavailable for database placement. For more information, see the Using disk space in a Redis cluster guide.
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 are not sure about your 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 table;
- 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 disks in RAID 1. The number of disks in a cluster depends on the configuration. To view disk performance and bandwidth for different lines, see the Performance and bandwidth table;
- 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).
* In DBMS clusters, Hyper-Threading Technology is used. Each physical core can process multiple threads in parallel—thanks to this, the total number of virtual cores (vCPU) exceeds the number of physical cores. This allows for more efficient load distribution during multi-threaded or analytical tasks.
** Part of the RAM is reserved for physical server service processes.
* ** Disks are combined into RAID 1—a disk array with mirroring 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 service processes.
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.
