	The UAB Research Network is currently a dedicated ~~40GE~~ optical ~~connection between the~~ UAB ~~Shared HPC Facility and the RUST Campus Data Center~~ to ~~create a multi-site facility housing~~ the ~~Research Computing System, which leverages the network for connecting storage~~ and compute hosting resources. The network supports direct connection to high-bandwidth regional networks and the capability to connect data intensive research facilities directly with the high performance computing services of the Research Computing System. This network can support very high speed secure connectivity between nodes connected to it for high speed file transfer of very large data sets without the concerns of interfering with other traffic on the campus backbone, ensuring predictable latencies. In addition, the network also consist of a secure Science DMZ with data transfer nodes (DTNs), Perfsonar measurement nodes, and a Bro security node connected directly to the border router that provide a "friction-free" pathway to access external data repositories as well as computational resources.		The UAB Research Network is currently a dedicated 40Gbps optical link. The UAB LAN provides 1Gbs to the desktop and 10Gbs for instruments.

	The ~~campus~~ network ~~backbone is based on~~ a ~~40 gigabit redundant Ethernet network~~ with ~~480 gigabit/second back-planes on~~ the ~~core L2/L3 Switch/Routers. For efficient management,~~ a collapsed backbone design is used. Each campus building is connected using 10 Gigabit Ethernet links over single mode optical fiber. Desktops are connected at 1 gigabits/second speed. The campus wireless network blankets classrooms, common areas and ~~most academic office buildings~~.		The research network also includes a secure Science DMZ with data transfer nodes (DTNs) connected directly to the border router that provide a "friction-free" pathway to access external data repositories and other computational resources.

	UAB connects to the Internet2 high-speed research network via the University of Alabama System Regional Optical Network (UASRON)~~, a University of Alabama System owned and operated DWDM Network offering 100Gbps Ethernet to the Southern Light Rail (SLR)/Southern Crossroads (SoX) in Atlanta, Ga~~. ~~The UASRON also connects UAB to UA~~, and UAH, the other two University of Alabama System institutions, and the Alabama Supercomputer Center. UAB is also connected to other universities and schools through Alabama Research and Education Network (AREN).		UAB connects to the Internet2 high-speed research network at 100 Gbs via the University of Alabama System Regional Optical Network (UASRON).

			Globus technologies provide secure, reliable and fast data transfers.

It includes 96 nodes: 2x12 core (2304~~ cores ~~total) 2.5 GHz Intel Xeon E5-2680 v3 compute nodes with FDR InfiniBand interconnect. Out of the 96 compute nodes~~, ~~36 nodes have 128 GB RAM, 38~~ nodes ~~have 256 GB RAM~~, and 14 nodes have 384 GB RAM. There are also four compute nodes with the Intel Xeon Phi 7210 accelerator cards and four compute nodes with the NVIDIA K80 GPUs. The newest generation is composed of 18 nodes: 2x14 core (504 cores total) 2.4GHz Intel Xeon E5-2680 v4 compute nodes ~~with 256GB RAM, four NVIDIA Tesla P100 16GB GPUs per node, and EDR InfiniBand interconnect~~. The compute nodes combine to provide over ~~468 TLOP/s~~ of dedicated computing power.		The UAB Cheaha High Performance Computing environment includes a high performance cluster with approximately 3744 CPU cores, 18 GPU nodes, and large memory nodes. The compute nodes combine to provide over 572 TFIops of dedicated computing power. The Ruffner OpenStack private cloud is available to develop and host scientific applications.
	~~In addition UAB researchers also have access~~ to ~~regional~~ and ~~national HPC resources such as Alabama Supercomputer Authority (ASA), XSEDE and Open Science Grid (OSG)~~.
