High performance

  • Up to two (2) processors Intel Xeon Scalable Gen3, each with a capacity of up to 270 Tue (Ice Lake).

  • 32 memory slots DDR4 ECC 3200 MHz (RDIMM/LRDIMM), of these, support for the installation of up to 16 non-volatile memory modules Intel Optane 200 Series (PMem).

Reliability and stability

  • A truly fault-tolerant architecture has been implemented, including power supplies and fans.

  • Support for modern operating systems: Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, CentOS, Ubuntu, FreeBSD – and virtualization systems: VMware ESXi, Linux KVM, Windows Hyper-V.

Flexible capabilities for organizing data storage and network I/O subsystems

36 universal compartments for 2.5” and 3.5” SATA/SAS drives with front and back sides and hot-swappable support.

1 OCP 3.0 slot for network card installation.

Up to 10 slots PCIe 4.0 (6 – full height, 4 – half height).

Half height PCIe slots can be replaced with hard drives by installing Two disk modules, supporting a total of up to four (4) 2.5” SATA/NVMe drives on the back side.

Support for installing graphics adapters (for example, NVIDIA A800), and a motherboard with two on-board M.2 NVMe 2280 interfaces.

Remote control

All vStack-R servers are equipped with an integrated management controller (Baseboard Management Controller, BMC) with support for IPMI 2.0 remote management and monitoring interface.
The operation of BMC does not depend on the server operating system and provides the following features through a dedicated 1Gb RJ45 port:

Configuring server hardware parameters, including BIOS and hardware RAID.


Real-time monitoring of the system status.


KVM over IP – remote access to the server's graphical console.


Virtual Media – remote connection of virtual media (CD/DVD images) to the server.


Power management: power on, power off, reboot.


Display of temperature sensor readings.


Secure access via SSL.


Multi-user access, including integration with Active Directory.
