This page describes the [[Research Computing Hardware]] used to '''build Father''' (running Windows 2019 server) and '''Mother''' (running Ubuntu Server 20.04). The hardware description and complete build notes and configuration information for '''Bastard''' are on the [[DIGITS DevBox]] page.
 
==Current Hardware==
<onlyinclude>The component lists for '''Father and Mother''', our two current research computing servers [[Research Computing Hardware]], are provided below. These parts work nicely together, which can be a challenge. Both machines use lots of common components - the same Supermicro boards, the same RAM, the same drives (more or less), etc. The boards were chosen because they support dual chip Intel Scalable CPUs on socket 3647, DDR4 at 2666MHz, have NVMe connections for the solid state drives (provided you remember to buy the oculink cables!), and have room for multiple GPUs using 16 channels of PCI-E 3.0(though the BIOS of this board seems to prevent them from working). The chips all have fast enough clock speeds to match the RAM, and sufficient channels for the drives and GPUs. Each machine has a RAID 10 array made up initially of 4 6TB NAS drives, which are in a hot-swappable bay.
===RDP Hardware Components===See [[Research Computing Configuration]] for how we set them up.
====Father's (RDP) Hardware Components==== The RDP has dual 12-core CPUs. We compromised on clock speed to save on price, but this is a good "all-purpose" configuration. The OS lives on the 400Gb NVMe SSD. Parallel compute is through the GPU. Currently this box has 512Gb of DDR4 2.666Ghz, but it is expandable to 1Tb. The board supports 2Tb but you need 16Gb 64Gb sticks, which are currently prohibitively expensive.

====Mother's (Dbase Server ) Components====
The database server has a single 4-core 3.6Ghz Skylake chip, as clock speed matters much more than cores in this set-up. The OS lives on a 400Gb NVMe SSD and the postgresql installation lives on the 1.2Tb NVMe SSD. The 12 TB RAID 10 array is for deep bulk storage. Because we only have a single CPU on the board, we are maxed out at 512Gb with the 8Gb sticks of DDR4 2.66Ghz.

==McNair Center Hardware==Bastard====
The old [[Computer Build]] notes provide details of the hardware. For the configuration build of the individual boxes see the old Bastard, our [[Center ITDIGITS DevBox]] , has its own page or the pages below:*[[Database Server Documentation]]*[[RDP Documentation]]**[[Server Backup Policy]]**[[Power Backup]]*[[Test Web Server Documentation]]*[[Web Server Documentation]]**[[Wiki Configuration]]**[[Security on the wiki]].
==UC Berkeley McNair Center Hardware==
At UC Berkeley, Ed designed and built three machines - two postgresql database servers and a wiki server. The documentation is here:*old [[Haas PhD Server ConfigurationComputer Build]]*[[Posgres Server Configuration]] -- documents notes provide details of the hardware for the three servers that we ran at the build of postgres2McNair Center.
