High-capacity primary storage subsystem
The primary storage subsystem in VEGMAN S220/S320 servers is built on SAS/SATA drives of the LFF form factor. As a result, storage cost per terabyte is very low. We placed the drives in several rows inside the chassis so that the storage space could be scaled to 512 TB while density — to 170.6 TB/U. At the same time, all drives in any row are hot-swappable and can be accessed individually.
Some types of data require the fastest access possible, e.g. log files, swap partitions, and application cache. To enable their convenient storage, VEGMAN servers can house up to four separate NVMe drives in the rear bays. These drives are connected directly to CPUs. If required, the same bays can host SATA drives connected to the RAID controller on the chipset.
To enable installation of operating systems and hypervisors, VEGMAN servers provide capability to install two SATA M.2 drives installed inside the chassis. By default, they are managed by an in-built RAID controller on the chipset. There is also an option to add a separate cost-effective RAID controller on the mezzanine board. This option is required to enable the installation of VMware® ESXi on M.2 drives due to the technical characteristics of this hypervisor.
