12 Hardware

CloudLab can allocate experiments on any one of several federated clusters.

CloudLab has the ability to dispatch experiments to several clusters: three that belong to CloudLab itself, plus several more that belong to federated projects.

Additional hardware expansions are planned, and descriptions of them can be found at https://www.cloudlab.us/hardware.php

12.1 CloudLab Utah

The CloudLab cluster at the University of Utah is being built in partnership with HP and Dell. It currently consists of 4 Intel Ice Lake servers, 208 AMD EPYC Rome servers (two generations), 200 Intel Xeon E5 servers, 270 Xeon-D servers, and 270 64-bit ARM servers for a total of 9,636 cores. The cluster is housed in the University of Utah’s Downtown Data Center in Salt Lake City.

There are 45 nodes in a chassis, and this cluster consists of twelve chassis. Each chassis has two 45XGc switches; each node is connected to both switches, and each chassis switch has four 40Gbps uplinks, for a total of 320Gbps of uplink capacity from each chassis. One switch is used for control traffic, connecting to the Internet, etc. The other is used to build experiment topologies, and should be used for most experimental purposes.

All chassis are interconnected through a large HP FlexFabric 12910 switch which has full bisection bandwidth internally.

We have plans to enable some users to allocate entire chassis; when allocated in this mode, it will be possible to have complete administrator control over the switches in addition to the nodes.

In phase two we added 50 Apollo R2200 chassis each with four HPE ProLiant XL170r server modules. Each server has 10 cores for a total of 2000 cores.

Two Dual-port Mellanox ConnectX-4 25 GB NIC (PCIe v3.0, 8 lanes (two ports available for experiment use, one 10Gb and one 25Gb)

Each server is connected via a 10Gbps control link (Dell switches) and a 25Gbps experimental link to Mellanox 2410 switches in groups of 40 servers. Each of the five groups’ experimental switches are connected to a Mellanox 2700 spine switch at 5x100Gbps. That switch in turn interconnects with the rest of the Utah CloudLab cluster via 6x40Gbps uplinks to the HP FlexFabric 12910 switch.

A unique feature of the phase two nodes is the addition of eight ONIE bootable "user allocatable" switches that can run a variety of Open Network OSes: six Dell S4048-ONs and two Mellanox MSN2410-BB2Fs. These switches and all 200 nodes are connected to two NetScout 3903 layer-1 switches, allowing flexible combinations of nodes and switches in an experiment. Note that links through the NetScout switches are only 10Gb, not 25Gb.

For phase two we also added 28 Dell AMD EPYC-based servers with dual 100Gb Ethernet ports.

The "-25g" variant nodes have 2 x 25Gb experiment links (Dell S5296F switches) and SATA-based SSDs, and are intended for general experimentation.

The "-100g" variant nodes have one 25Gb (Dell S5296) and one 100Gb (Dell Z9264) experiment link as well as two large NVMe-based SSDs and more cores, and are intended for network and storage intensive experimentation.

Each server is also connected via a 25Gbps control link (Dell S5296F switch).

The experiment switches are interconnected via a single Dell Z9332 using 4-8 100Gb links each.

In the second installment of phase three (early 2022), we added a small set of "expandable" nodes, 2U boxes with multiple PCIe slots available for add in devices such as GPUs, FPGA, or other accelerator cards.

These machines have four available full-length double-wide PCIe v4 x16 slots and 2400W power supplies capable of handling four enterprise GPUs or other accelerator cards.

They also have a 400GB Optane write-intensive SSD providing another level of storage hierarchy for experimentation.

The Utah Cloudlab cluster includes a storage server for remote datasets. The server currently has 80TB available for allocation.

12.2 CloudLab Wisconsin

The CloudLab cluster at the University of Wisconsin is built in partnership with Cisco, Seagate, and HP. The cluster, which is in Madison, Wisconsin, has 523 servers with a total of 10,060 cores connected in a CLOS topology with full bisection bandwidth. It has 1,396 TB of storage, including SSDs on every node.

NIC

   

1 x Solarflare Dual port SFC9120 10G Ethernet NIC

There is some variation within the rs620 and rs630 nodes, primarily with the CPUs.

On these nodes, the control/Internet connections is a 1Gbps port and one of the 10Gbps interfaces on each node is used for the experiment network.

There is currently no remote dataset capability at the UMass cluster.

12.6 OneLab

The OneLab facility at Sorbonne University in Paris hosts a small cluster modeled after part of the Utah hardware, with one chassis of ARM64 servers. In addition to this cluster, which is available to all CloudLab users through the CloudLab interface, OneLab hosts a large number of other experiment environments, including clusters, IoT devices, and software defined networks. See the OneLab website for a complete list.
