Service settings


  • Editions of MS SQL: Web, Standard, Enterprise.
  • Database volume: from 1 GB and more.
  • Virtual server size: vCPU up to 32 cores, RAM up to 512 GB.
  • Disk subsystem: SSD 2000 IOPS/1000GB.
  • Backup: Once a day, copies are stored for 7 days.

Additional options

  • LIGHT – database for experiments, without SLA, backup and maintenance.
  • FREE LICENSE – use of client's own MS SQL licenses.
  • Deployment of the database in the cloud in compliance with 152-FL.
  • Customizing the individual schedule of the backup.
  • Building a disaster-proof solution.

We offer such configurations:

  • We will configure connectivity of Cloud and your Hardware located in DataLine Data Center, via established link.
  • Fail-safety from HA virtualization.
  • It is possible to deploy the DB in Cloud that is 152-FZ copliant.
Clustered: AlwaysOn Failover Clustering Instances
  • Active-Passive mode: when DB1 functioning properly, DB2 will not receive requests. DB2 starts receiving the request only after switching, when DB1 vise versa switches to waiting mode.
Clustered: AlwaysON Availability Groups
  • Active-Active mode support (Enterprise license required):
    — Request goes to one DB
    — Reading performed from replica (up to 8 replicas)
  • Ideal for “heavyweight” reports.

For high-capacity data bases:

Cluster and standalone solution at S2D infrastructure

DBMS located in virtual machines, at dedicated hyperconverged cluster.

Storage at Storage Spaces Direct using Intel Optane technology and NVME discs DC P4510.
