Riistvara
Arvutikomplekti komponentide koosseis
- emaplaat - Asrock Taichi X570
- protsessor - AMD Ryzen 5500
- mälu - 4 x 32 GB
- toiteplokk -
- videokaart - Nvidia quadro k600 (lspci: 'NVIDIA Corporation GK107GL [Quadro K600]')
- nvme seade - 2 x 'Samsung SSD 990 PRO with Heatsink 4TB'
- nvme seade - 2 x 'micron 7450 pro u.3'
pcie nvme adapteri kasutamine
nvme u.3 micron 7450 pro plokkseade, iseloomulikud kontaktid (andmed + toide)
salvestuskomplekt
- kaks nvme ketast
- supermicro AOC-SLG4-4E4T pcie nvme adapter
- ühenduskaablid (toide tuleb tavalise nn molex küljest)
andmekaabli kontaktid, kinnitub adapteri kaardi külge ja ühendab ketta
kus
- valge lapik kontakt ja tema vastus kaardil on 'slimsas' ehk 'sff-8654 8i' - tavaliselt x8 pcie laiune, st teenindab ära kaks nvme ketast (antud juhul nii kasutatakse)
- valge lapik kontakt ei ole MCIO (Mini Cool Edge IO) - tavaliselt x8 pcie laiune, st teenindab ära kaks nvme ketast (antud juhul nii kasutatakse)
arvuti bios/setup keskkond, tuleb väljendada, et pci liides töötab bifurcation režiimis - paistab, et antud juhul saab kasutada kahte x4 kanalit ja ka füüsilisi kettaid on parasjagu kaks
muud bifurcation valikud
Sissevaada arvuti korpusse, nö kõige kangemas pesas on videokaart, siis võrgukaart ja kõnealune storage adapter
Tulemusena on arvutis operatsioonisüsteemi jaoks olemas kaks füüsilist ketast

202605 - ebastabiilsuse parandamine
gemini.google vestluses tekkis hüpotees, et kasutuses olev protsessor Ryzen 5 5500' on üsna tagasihoidlik seade
- toetab kuni pcie v. 3.0
- algselt laptop kasutusjuhule orienteeritud
- mitte-paindlik pcie ressursside esitamises (nt iommu abil grupeerimine)
- materjalivaliku osas mitte kõige kvaliteetsem (signaalide läbikostvus, müra jms)
ja hüpotees, et protsessor 'Ryzen 9 5900XT' võiks anda palju parema tulemuse
- toetab kuni pcie v. 4.0
- pigem serveri laadne, ja downgrade'itud desktop kasutusjuhuks
- pcie ressursside paindlik korraldamine (nt bifurcation osakonda ilmus juurde mõni valik (nt 4 x4)
- kvaliteetsemad materjalid, võimsam signaal pcie peal jne
ning tõesti, tulemus on looduses palju parem

kus
- 8 GT/s downgrade'isid ei ole (nt nvme x4 pcie seadmed töötavad oma loomuliku x4 ehk 16 GT/s kiiruse lane'iga)
- LaneErr esineb ainult 00:01.3 juures, paistab, et seal on üks seade ja oluline seade, gemini arvates on see lingi kokkuleppimise ühekordne nähtus, eriti arvestades, et süsteem säilitab kiirust 16 GT/s, näis

20260530 - bifurcation märkused
SuperMicro nvme retimer kaardi kasutamist aitab
- bios juures bifruction valikute vahel katsetamine (4 x4, 2 x8 jne)
- füüsiliste kaablite ühendamine ringi nt ühe Y kaabli küljes on kaks seadete; kummagi Y kaabli küljes on üks seade
- pcie kaardi passimine ühte ja teisse pcie füüsilisse pessa (tõenäoliselt on kõige parem kaarti paigutada nn video kaardi pessa)
- videokaardina võiks kasutada midagi võimalikult tagasihoidlikku, nt pcie v. 2.0 nvidia midagi 56 euro eest; ja nö madalas pcie pesas
Kasulikud lisamaterjalid
