Dual-socket tower server with UPS

The Lenovo ThinkSystem ST650 is a tower server system built for small-business workloads. It ships with dual Intel Xeon Silver 4309Y processors, 128GB DDR4 unbuffered memory, 2TB of SATA SSD storage and 24TB of SATA HDD capacity. An APC 1500VA sine-wave UPS is included for battery backup and surge protection.

Suited for general-purpose business tasks.

This configuration targets file, print, database and virtualisation roles that benefit from dual-socket compute and large mixed storage. The Matrox G200 graphics provide basic display output only, so buyers needing GPU acceleration should consider other platforms. A single power supply is fitted, so organisations requiring redundant power will need a different chassis.

Dual 8-core Xeon Silver 4309Y CPUs at 2.80GHz base

The two processors deliver 16 cores total with a 3.60GHz turbo frequency, defining the compute ceiling for every application on this server. Memory runs at 2666MHz DDR4 and storage uses SATA 6Gb/s for both SSDs and HDDs. Network connectivity provides two 1GbE ports plus a dedicated management port.

Questions about this item

Does the bundle ship with the APC UPS already in the box or do I need to order it separately?

The APC Back-UPS Pro 1500VA is included as part of the bundle.

The listing shows 128GB DDR4 at 2666MHz — is that the maximum speed the CPUs support?

The Xeon Silver 4309Y processors support DDR4 up to 2666MHz, so the installed memory runs at the native speed.

With two 1TB SSDs and six 4TB HDDs, what usable capacity can I expect after RAID?

RAID 1 on the SSDs yields 1TB usable; RAID 5 on the six HDDs yields roughly 20TB usable.
