| 8 | A Pronto deployment must have a detailed plan of the network topology and |
| 9 | devices, and required cabling before being put assembled. |
| 10 | |
| 11 | Once planning is complete, equipment should be ordered to match the plan. The |
| 12 | VAR we've used for most Pronto equipment is ASA (aka "RackLive"). |
| 13 | |
| 14 | Network Cable Plan |
| 15 | ------------------ |
| 16 | |
| 17 | If a 2x2 TOST fabric is used it should be configured as a :doc:`Single-Stage |
| 18 | Leaf-Spine <trellis:supported-topology>`. |
| 19 | |
| 20 | - The links between each leaf and spine switch must be made up of two separate |
| 21 | cables. |
| 22 | |
| 23 | - Each compute server is dual-homed via a separate cable to two different leaf |
| 24 | switches (as in the "paired switches" diagrams). |
| 25 | |
| 26 | If only a single P4 switch is used, the :doc:`Simple |
| 27 | <trellis:supported-topology>` topology is used, with two connections from each |
| 28 | compute server to the single switch |
| 29 | |
| 30 | Additionally a non-fabric switch is required to provide a set of management |
| 31 | networks. This management switch is configured with multiple VLANs to separate |
| 32 | the management plane, fabric, and the out-of-band and lights out management |
| 33 | connections on the equipment. |
| 34 | |
| 35 | |
| 36 | Required Hardware |
| 37 | ----------------- |
| 38 | |
| 39 | Fabric Switches |
| 40 | """"""""""""""" |
| 41 | |
| 42 | Pronto currently uses fabric switches based on the Intel (was Barefoot) Tofino |
| 43 | chipset. There are multiple variants of this switching chipset, with different |
| 44 | speeds and capabilities. |
| 45 | |
| 46 | The specific hardware models in use in Pronto: |
| 47 | |
| 48 | * `EdgeCore Wedge100BF-32X |
| 49 | <https://www.edge-core.com/productsInfo.php?cls=1&cls2=180&cls3=181&id=335>`_ |
| 50 | - a "Dual Pipe" chipset variant, used for the Spine switches |
| 51 | |
| 52 | * `EdgeCore Wedge100BF-32QS |
| 53 | <https://www.edge-core.com/productsInfo.php?cls=1&cls2=180&cls3=181&id=770>`_ |
| 54 | - a "Quad Pipe" chipset variant, used for the Leaf switches |
| 55 | |
| 56 | Compute Servers |
| 57 | """"""""""""""" |
| 58 | |
| 59 | These servers run Kubernetes and edge applications. |
| 60 | |
| 61 | The requirements for these servers: |
| 62 | |
| 63 | * AMD64 (aka x86-64) architecture |
| 64 | * Sufficient resources to run Kubernetes |
| 65 | * Two 40GbE or 100GbE Ethernet connections to the fabric switches |
| 66 | * One management 1GbE port |
| 67 | |
| 68 | The specific hardware models in use in Pronto: |
| 69 | |
| 70 | * `Supermicro 6019U-TRTP2 |
| 71 | <https://www.supermicro.com/en/products/system/1U/6019/SYS-6019U-TRTP2.cfm>`_ |
| 72 | 1U server |
| 73 | |
| 74 | * `Supermicro 6029U-TR4 |
| 75 | <https://www.supermicro.com/en/products/system/2U/6029/SYS-6029U-TR4.cfm>`_ |
| 76 | 2U server |
| 77 | |
| 78 | These servers are configured with: |
| 79 | |
| 80 | * 2x `Intel Xeon 5220R CPUs |
| 81 | <https://ark.intel.com/content/www/us/en/ark/products/199354/intel-xeon-gold-5220r-processor-35-75m-cache-2-20-ghz.html>`_, |
| 82 | each with 24 cores, 48 threads |
| 83 | * 384GB of DDR4 Memory, made up with 12x 16GB ECC DIMMs |
| 84 | * 2TB of nVME Flash Storage |
| 85 | * 2x 6TB SATA Disk storage |
| 86 | * 2x 40GbE ports using an XL710QDA2 NIC |
| 87 | |
| 88 | The 1U servers additionally have: |
| 89 | |
| 90 | - 2x 1GbE copper network ports |
| 91 | - 2x 10GbE SFP+ network ports |
| 92 | |
| 93 | The 2U servers have: |
| 94 | |
| 95 | - 4x 1GbE copper network ports |
| 96 | |
| 97 | Management Server |
| 98 | """"""""""""""""" |
| 99 | |
| 100 | One management server is required, which must have at least two 1GbE network |
| 101 | ports, and runs a variety of network services to support the edge. |
| 102 | |
| 103 | The model used in Pronto is a `Supermicro 5019D-FTN4 |
| 104 | <https://www.supermicro.com/en/Aplus/system/Embedded/AS-5019D-FTN4.cfm>`_ |
| 105 | |
| 106 | Which is configured with: |
| 107 | |
| 108 | * AMD Epyc 3251 CPU with 8 cores, 16 threads |
| 109 | * 32GB of DDR4 memory, in 2x 16GB ECC DIMMs |
| 110 | * 1TB of nVME Flash storage |
| 111 | * 4x 1GbE copper network ports |
| 112 | |
| 113 | Management Switch |
| 114 | """"""""""""""""" |
| 115 | |
| 116 | This switch connects the configuration interfaces and management networks on |
| 117 | all the servers and switches together. |
| 118 | |
| 119 | In the Pronto deployment this hardware is a `HP/Aruba 2540 Series JL356A |
| 120 | <https://www.arubanetworks.com/products/switches/access/2540-series/>`_. |
