NVMe Over Fabrics (NVMeOF)
Direct Attached NVMe Storage is Fast & Efficient, but Still Has Limitations…
- Direct attached NVMe storage has limited scalability, as PCIe is inherently not designed for expansion far outside the box.
- Direct attached storage offers little or no support for sharing of flash resources amongst multiple servers. Servers can only access flash in their own chassis.
- No sharing leads to storage utilization inefficiency and resource waste. Underutilized “stranded” or “dark” flash can be an issue
Bringing Scale-Out NVMe Storage Capabilities Independent of Compute
NVMe-OF enables NVMe-based communication over interconnects (“fabrics”) other than PCIe. This interface makes it possible to connect “external” storage enclosures to a server, either directly or through a switch, while still using NVMe as the fundamental communication mechanism. Flash storage can then be scaled out independent of compute.
Enabling Resource Disaggregation + Pooling to Maximize Efficiency & Minimize Under-utilization
Combined with virtualization, the amount and type of each resource (CPU, GPU, storage, networking) can be selected for each workload independent of where that resource is physically located in the data center.

Carefully Selected Components
GIGABYTE’s passive components are carefully selected to guarantee a stable operating environment and allow the processors and the memory to deliver their maximum performance. GIGABYTE’s server motherboards are built with long lasting components for a high degree of reliability and durability.
Design Features for Easy Maintenance
GIGABYTE platforms contain many tool less design features for easy installation, maintenance and removal – never worry about forgetting your toolbox or losing a screw again!
Tool-less Rail Kits
Rail kits attach to the side of the server chassis via clipping mechanism.
Tool-less 2.5” & 3.5” Drive Bays
Clipping mechanism secures the drive in place. Install or replace a new drive in seconds.
Efficient, Reliable Power Supply
GIGABYTE server are designed to guarantee high conversion efficiency regardless of load. Redundant 80 Plus ‘Titanium’ or ‘Platinum’ PSUs, combined with GIGABYTE’s precision engineering, translates to super efficient power usage which maximizes the system’s power : performance ratio and reduces OPEX for the user.
Dynamic Fan Speed Control
GIGABYTE servers are enabled with dynamic fan speed adjustment. Individual fan speed will be automatically adjusted according to the system’s current temperature (according to CPU, DIMM, M.2, HDD, GPU temperature sensors), to achieve the best cooling and power efficiency. When the BMC detects a temperature change, fan speed will be automatically adjusted accordingly. Fan speed profiles may also be manually created and edited* when necessary according to the user’s custom requirements.
