# Redis versions and configurations

## Versions \{#versions}

Redis versions 6 and 8 are supported.

## Node configurations \{#node-configurations}

When [creating a Redis Managed Database cluster](/managed-databases/redis/create-cluster.mdx), you can select the node configuration—the number of vCPUs, RAM, and disk size.

The available node configurations are divided into [lines](#configuration-lines). Depending on the line, configuration, and [pool](/infrastructure/locations.mdx#pool), different [processors](#available-processors) and [disks are used](/managed-databases/redis/volumes.mdx).

When choosing a configuration, please note that part of the disk space is reserved for service needs and is unavailable for database placement. For more details, see the instructions [Using disk space in a Redis cluster](/managed-databases/redis/use-disk-space.mdx).

After creating a cluster, you can change the node configuration by [scaling the cluster](/managed-databases/redis/resize-cluster.mdx).

## Configuration lines \{#configuration-lines}

In all configuration lines, the resource ratio is fixed.

To view the availability of configuration lineups across locations, see the table in [Managed Databases availability by location](/managed-databases/about/managed-databases-availability-by-location.mdx).

### Standard \{#standard-line}

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. To view processor frequencies across lineups, see the table [Processors](#available-processors).

To view disk performance and bandwidth across lineups, see the table [Performance and Bandwidth](/managed-databases/kafka/volumes.mdx#performance-and-bandwidth).

### Dedicated \{#dedicated-line}

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. To view processor types and frequencies across lineups, see the table [Processors](#available-processors);
* 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. To view disk performance and bandwidth across lineups, see the table [Performance and Bandwidth](/managed-databases/redis/volumes.mdx#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 (Hyper-Threading Technology). Each physical core can process multiple threads concurrently — because of this, the total number of virtual cores (vCPUs) exceeds the number of physical cores. This allows for more efficient load distribution during multithreaded or analytical tasks.

` **` Part of the RAM is reserved for the physical server services.

` * **` Disks are combined into RAID 1 — a mirrored disk 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 the physical server services.

## Processors \{#available-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.
