Taipei, Taiwan, 8 May 2018 - GIGABYTE, an industry leader in server hardware for high performance computing, has released two new powerful 4U GPU servers to bring massive parallel computing capabilities into your datacenter: the 8 x SXM2 GPU G481-S80, and the 10 x GPGPU G481-HA0. Both products offer some of the highest GPU density of this form factor available on the market.
Dual Intel Xeon Scalable Processors
Both G481-S80 and G481-HA0 are powered by dual Intel Xeon Scalable processors, with up to 28 cores per CPU. Each socket supports the highest CPU thermal design power requirement of 205W, as well as Intel's Omni-Path connection technology to eliminate CPU to network latency. Each model features 24 x DIMM slots (12 per socket) for a total capacity of over 3TB of memory, and will both also be fully compatible with Intel's upcoming Optane DC Persistent Memory.

GPU Capacity & Interconnection
The G481-S80 accommodates up to 8 x SXM2 NVIDIA Volta V100 GPUs, with support for NVLink™ GPU to GPU interconnection, offering higher bandwidth, more links, and improved scalability. For example, a single NVIDIA Tesla® V100 GPU can support up to six NVLink™ links with a signaling rate of 25 GB/second in each direction, equaling a total bandwidth of 300 GB/sec. Meanwhile, the G481-HA0 can accommodate up to 10 x PCIe GPGPU cards. The G481-HA0 is configured to a dual root architecture as standard, but will also be available in a single-root configuration variant (G481-HA1). Both these systems are among the maximum GPU density systems available in this form factor currently available on the market.
G481-HA0 FRONT & REAR
Expansion for GPU to Network Interconnect
Located in the rear of the G481-S80’s GPU bay are 4 x PCIe expansion slots to support network connectivity, such as InfiniBand for RDMA (Remote Direct Memory Access), permitting high-throughput, low latency GPU to network connectivity for each GPU pair. Meanwhile for the G481-HA0, in addition to a PCIe expansion slot offered in the rear suitable for networking expansion, the user may choose to install additional networking connection possibilities in one of the PCIe expansion slots instead of a GPU card (for example, they may choose to install 8 x GPU cards and 2 x additional networking cards such as InfiniBand or 10 / 25 / 50 / 100 Gb Ethernet).
Additional Networking & Expansion Options
The G481-HA0 features dual 10Gb/s BASE-T LAN ports in the rear as standard. The G481-S80 does not feature this as standard but features a rear OCP mezzanine expansion slot to provide additional networking connectivity options. Both the G481-S80 and the G481-HA0 also feature dual 1GbE LAN ports at the front of each unit, as well as 1Gb dedicated management LAN ports in both the front and rear, giving the user connection flexibility depending on their cable routing arrangement.
Storage wise, the G481-S80 features 10 x 2.5” hot swap drive bays in the front, which can support 4 x ultra-fast NVMe drives via U.2 connection, and 6 x drives via SATA/SAS. Meanwhile, the G481-HA0 offers excellent storage capacity and flexibility, with 10 x 2.5” hot swap drive bays available for up to 8 x 2.5” NVMe drives and 2 x 2.5” SATA/SAS drives (or the customer may choose an alternative combination such as 6 x NVMe and 6 x SATA/SAS). Featured below the 2.5” storage drive area are a further 12 x 3.5” SATA/SAS hot swap drive bays. Both models also feature a PCIe expansion slot in the front above the storage area to attach a hardware or software RAID card, with an additional slot for a battery backup unit.
Power & Cooling
These models have been designed for excellent cooling efficiency with a dual fan wall (12 fans in total) between the GPU and CPU area to create a large airflow tunnel, and these fans are also hot swappable. Power wise, the G481-S80 features 4 x 80 PLUS Platinum 2200W power supply units, 3 units for main system power and 1 back-up for a N + N redundancy, while the G481-HA0 features 3 x 80 PLUS Platinum 2200W power supply units for a N + 1 redundancy.
