Taipei, Taiwan, 15th November 2018 – To offer more flexibility and choice for our customer’s needs in HPC computing and deep learning, GIGABTYE has released two new lower-cost versions to our popular G481 series of GPU servers: G481-H80 and G481-H81. GIGABYTE’s G481 series offers a high density and cost effective 4U PCIe-type GPU / GPGPU solution to bring massive parallel computing capabilities into your datacenter.

Dual Intel Xeon Scalable Processors
Both G481-H80 and H81 are powered by dual Intel Xeon Scalable processors, with up to 28 cores per CPU. Each socket can support the highest CPU TDP requirement of 205W, as well as Intel's Omni-Path connection technology. Four QSFP28 LAN ports with Intel^® Omni-Path Host Fabric Interface may be added to the front I/O as an option, providing 25Gb/s bandwidth per port and 100Gb/s bandwidth in total. Memory wise, each model features 24 x DIMM slots (12 per socket) for a total capacity of over 3TB of memory, and will also be fully compatible with Intel's upcoming Optane DC Persistent Memory.

GPU / GPGPU Capacity
Both the G481-H80 and H81 can accommodate up to 8 double-slot PCIe GPGPU cards such as NVIDIA’s Tesla V100. The user may also wish to alternatively utilize several expansion slots to install high speed networking connectivity products such as Mellanox InfiniBand EDR or 100GbE Ethernet cards.

Storage & Power Features
In order to reduce material cost, these two new models reduce some storage and power capacity that may be in excess of the user’s need compared with the original full spec G481-HA0 model. G481-H80 provides support for 10 x 2.5” (2 x NVMe, 8 x SATA/SAS) hot-swap drives, while G481-H81 provides support for 8 x 3.5” SATA/SAS hot swap drives as standard, with an additional 4 x 3.5” SATA/SAS drives available via an optional RAID card. Power wise, G481-H80 and H81 both feature triple 1600W 80 PLUS Platinum redundant power supplies.

Networking, Expansion & Cooling Features
Standard networking connectivity is provided by dual 10GbE BASE-T LAN ports at the rear and dual 1GbE LAN ports at the front of each unit, as well as dedicated management LAN ports at both the front and rear, giving the user connection flexibility depending on their cable routing arrangement. And apart from 8 x full height full length PCIe (Gen3 x16) expansion slots dedicated for GPUs, G481-H80 and H81 both feature a half-length low profile PCIe (Gen3 x 16) expansion slot located at the rear, while G481-H81 also features an additional half-length low profile PCIe (Gen3 x8) expansion slot located at the front of the unit. 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.

A comparison table of these two new models compared with the original G481-HA0 can be seen below:
