Redis versions and configurations
Versions
Redis version 6 is supported.
Node configurations
When creating a Redis cloud database cluster you can select the required number of vCPUs, RAM and size for nodes local disk.
Only available fixed configurations.
Processors used depend on the selected fixed configuration line.
About 5 GB of local disk space in all configurations is reserved for the operating system, service components, and log storage. The remaining space is available for database storage.
Once the cluster is created, you can reconfigure nodes.
Processors
The fixed-configuration and custom-configuration product lines differ in available processors. The processor frequency affects the speed of processing user requests, executing complex algorithms and data operations.
To see the availability of configurations in the regions, see the availability matrix Cloud databases.
* At 100% cloud server load, the processor runs with Turbo Boost technology and a maximum frequency of 3.6 GHz for the HighFreq lineup and 3.9 GHz for the Dedicated lineup. Since the processor is emulated, the test will display 3.00 GHz for the HighFreq lineup and 2.6 GHz for the Dedicated lineup.
Fixed configurations
To see the availability of configurations in the regions, see the availability matrix Managed databases.
The fixed configuration can be selected when creation or scaling cluster in the control panel and through Terraform.
Standard
A line of fixed configurations with a 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™ 2.2-2.4 GHz processors are used. To see the processor frequency in different configurations, see the table below Processors.
HighFreq
A line of fixed configurations with a balanced vCPU:RAM ratio.
High-performance Enterprise-level equipment is used:
- Intel® Xeon® Gold 6354 processors with Turbo Boost frequency up to 3.6 GHz. To see the processor frequency in different configurations, see the table below Processors;
- RAM ECC Reg 3.2 GHz;
- SSD NVMe disks with enhanced performance.
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® Gold 6240 processor with Turbo Boost speed up to 3.9 GHz. To see the processor frequency in different configurations, please refer to the table below Processors;
- RAM 64 GB DDR4 ECC Reg;
- two SSD NVMe disks in RAID 1;
- 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 increase the performance of the DBMS cluster, Hyper-Threading Technology is used. This technology allows you to use 34 vCPUs on the basis of physical 18 CPUs. This performance is suitable for highly loaded systems or analytical load profile.
** One slice 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.
