Redis versions and configurations
Versions
Redis versions 6 and 8 are supported.
Node configurations
When creating a Managed Service for Redis cluster, you can select the node configuration: number of vCPUs, RAM, and disk size.
Available node configurations are divided into lines. Depending on the line, configuration, and pool, different processors and disks are used.
When selecting a configuration, keep in mind that part of the disk space is reserved for system needs and is not available for hosting databases. For more information, see the Using disk space in a Redis cluster instructions.
After creating a cluster, you can change the node configuration — scale the cluster.
Configuration lines
In all configuration lines, the resource ratio is fixed.
You can check the availability of configuration lines in locations in the Managed Databases availability by location instructions.
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 the processor clock speed in different lines in the Processors table.
You can check the disk performance and bandwidth in different lines in 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 (in the ru-9, ru-2, ru-8, ke-1 pools) or AMD EPYC 9474F processors (in the ru-3, ru-7, uz-1, and uz-2 pools). You can view the processor clock speed in different lines in the Processors table;
- RAM ECC Reg 3.2 GHz (in pools ru-9, ru-2, ru-8, ke-1) or RAM DDR5 ECC Reg 4.8 GHz (in pools ru-3, ru-7, uz-1, and uz-2);
- High-performance NVMe SSDs. You can check the disk performance and bandwidth in different lines in 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 the processor type and clock speed in 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;
- NVMe SSDs in RAID 1. The number of disks in the cluster depends on the configuration. You can check the disk performance and bandwidth in different lines in 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).
* DBMS clusters use Hyper-Threading Technology. Each physical core can process multiple threads concurrently, so the total number of virtual cores (vCPUs) exceeds the number of physical cores. This allows for more efficient load distribution in multithreaded or analytical workloads.
** Part of the RAM is reserved for the physical server's system services.
* ** Disks are combined into RAID 1, a mirrored disk array that provides additional fault tolerance. When mirroring is used, 50% of the total disk space is available for databases. Part of the disk space is also reserved for the physical server's system 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.
