Redis versions and configurations
Versions
Redis version 6 is supported.
Node configurations
When creating a Redis cloud database cluster you can select node configuration — number of vCPUs, RAM and disk size.
The available node configurations are divided into rulers.
When selecting a configuration, consider that about 5 GB of disk space in all configurations is reserved for the operating system, service components, and log storage. The rest of the disk space is available for databases.
Once the cluster has been created, you can change the configuration of the nodes — cluster scale.
Configuration lines
The available node configurations are divided into rulers. The selected line of configurations depends on the configurations used processors and disks.
In all line configurations, the resource ratio is fixed.
To see the availability of configurations in the regions, see the availability matrix Managed databases.
Standard
A line of fixed configurations with local disk and balanced vCPU:RAM ratio, suitable for most DBMSs. We recommend using this lineup if you do not know the load profile.
Intel® Xeon® Scalable or AMD EPYC™ processors are used. See the table below to view processor frequencies in different configuration lines Processors.
To see the performance and throughput of the drives in the different lines, see the table below Performance and throughput.
HighFreq
A line of fixed configurations with a balanced vCPU:RAM ratio.
High-performance Enterprise-level equipment 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). To see processor frequencies in different configuration lines see the table below Processors;
- 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);
- SSD NVMe disks with higher performance. See the table below to see the performance and throughput of the drives in the different product lines Performance and throughput.
Dedicated
A line of fixed configurations with cluster nodes on separate cloud servers. Each cloud server occupies the entire dedicated host (physical server). Suitable for users who require physical isolation of databases from other clients, maximum performance and maximum size of available resources.
High-performance Enterprise-level equipment is used:
- one Intel® Xeon® W-2255 (Small configuration) or Intel® Xeon® Gold 6240 (Medium, Large and Extra Large configurations). To see the frequency of processors in different lines, please refer to the table below Processors;
- RAM 64 GB DDR4 ECC Reg;
- two SSD NVMe disks in RAID 1. To see the performance and throughput of the disks in different ranges, see the table below Performance and throughput;
- two 2 × 25 GE NICs for the main network + MC-LAG with 25 Gbps connection speed for the service network (for backup, monitoring, data replication in the cluster).
* To improve the performance of the DBMS cluster, Hyper-Threading Technology is used. This technology allows you to use 34 vCPUs based on the physical 18 CPUs. This performance is suitable for highly loaded systems or analytical load profile.
** One slate of RAM is reserved for the services that maintain the physical server.
*** To provide additional fault tolerance, the disks are placed in RAID 1. RAID 1 uses mirroring, so 50% of the disk space is available for the database. Part of the disk space is also reserved for services that maintain the physical server.
Processors
The fixed-configuration and random-configuration product lines differ in available processors. Processor frequency affects the speed of processing user requests, performing complex algorithms and data operations. When the cloud server load is 100%, the processor runs with Turbo Boost technology. Since the processor is emulated, a lower frequency will be displayed during testing.
