Amaseva anamaphrosesa asekelwe ekwakhiweni kwe-arm64 angena ngenkuthalo ezimpilweni zethu. Kulesi sihloko sizokukhombisa i-unboxing, ukufakwa kanye nokuhlolwa okufushane kweseva entsha ye-TaiShan 2280v2.
Iyavula
Iseva ifike kithi ngebhokisi elingaphawuleki. Izinhlangothi zebhokisi zinelogo ye-Huawei, kanye ne-container kanye namamaki okupakisha. Phezulu ungabona imiyalelo yokuthi ungayikhipha kanjani iseva kahle ebhokisini. Ake siqale ukukhipha!
Iseva isongwe ngesendlalelo se-antistatic futhi ibekwe phakathi kwezingqimba zegwebu. Ngokuvamile, ukupakishwa okujwayelekile kweseva.
Ebhokisini elincane ungathola isilayidi, amabhawodi amabili nezintambo zikagesi ze-Schuko-C13 ezimbili. Isihlibhi sibukeka silula ngokwanele, kodwa sizokhuluma ngalokho kamuva.
Phezulu kweseva kukhona ulwazi mayelana nale seva, kanye nokufinyelela kumojula ye-BMC kanye ne-BIOS. Inombolo yomkhiqizo imelwe ibhakhodi enohlangothi olulodwa, futhi ikhodi ye-QR iqukethe isixhumanisi sesayithi losekelo lobuchwepheshe.
Masisuse isembozo seseva futhi sibheke ngaphakathi.
Yini ngaphakathi?
Ikhava yeseva ibanjwe endaweni nge-latch ekhethekile, engavikelwa esimweni esivaliwe nge-screwdriver ye-Phillips. Ukuvula i-latch kubangela ukuthi ikhava yeseva ishelele, ngemva kwalokho ikhava ingasuswa ngaphandle kwezinkinga.
Iseva iza ekucushweni osekwenziwe okubizwa ngokuthi I-TaiShan 2280 V2 512G Ukucushwa Okujwayelekile ekucushweni okulandelayo:
- I-2x Kunpeng 920 (izakhiwo ze-ARM64, ama-cores angu-64, imvamisa yesisekelo 2.6 GHz);
- 16x DDR4-2933 32GB (ingqikithi 512 GB);
- 12x SAS HDD 1200GB;
- isilawuli se-RAID yehadiwe i-Avago 3508 enesipele samandla esisekelwe ku-ionistor;
- Ikhadi lenethiwekhi le-2x elinezimbobo ezine ze-1GE;
- Ikhadi lenethiwekhi le-2x elinamachweba amane we-10GE/25GE SFP+;
- 2x amandla kagesi 2000 watt;
- Ikesi le-Rackmount 2U.
I-motherboard yeseva isebenzisa izinga le-PCI Express 4.0, elikuvumela ukuthi usebenzise amandla aphelele amakhadi enethiwekhi angu-4x 25GE.
Ekucushweni kweseva esithunyelwe kithi, izikhala ze-RAM eziyi-16 azinalutho. Ngokomzimba, iprosesa ye-Kunpeng 920 isekela kufika ku-2 TB ye-RAM, ekuvumela ukuthi ufake i-memory sticks ye-32 ye-128 GB ngayinye, ukwandisa inani le-RAM ku-4 TB endaweni yesikhulumi esisodwa se-hardware.
Amaprosesa anama-radiator akhiphekayo ngaphandle kwabalandeli bawo. Ngokuphambene nalokho okulindelekile, amaphrosesa adayiswa ebhodini lomama (BGA) futhi uma kwenzeka ehluleka angashintshwa kuphela esikhungweni sesevisi kusetshenziswa imishini ekhethekile.
Manje ake sibuyisele iseva ndawonye futhi siqhubekele ekufakeni ama-rack.
Umhlangano
Okokuqala, ama-slides afakwe ku-rack. Amaslayidi angamashalofu alula lapho iseva ibekwe khona. Ngakolunye uhlangothi, lesi sixazululo silula kakhulu futhi silula, kodwa akunakwenzeka ukusevisa iseva ngaphandle kokuyikhipha ku-rack.
Uma iqhathaniswa namanye amaseva, i-TaiShan idonsa ukunaka ngephaneli yayo yangaphambili eyisicaba kanye nohlelo lombala oluhlaza nomnyama. Ngokwehlukana, ngingathanda ukuqaphela ukuthi umkhiqizi uyazwela ekulebeni kwezinto zokusebenza ezifakwe kuseva. Isiphathi sediski ngasinye siqukethe ulwazi oludingekayo mayelana nediski efakiwe, futhi ngaphansi kwembobo ye-VGA kukhona isithonjana esibonisa ukuhleleka kwezinombolo zediski.
Imbobo ye-VGA nezimbobo ze-USB ezingu-2 kuphaneli engaphambili ziyibhonasi enhle evela kumkhiqizi ngaphezu kwezimbobo ezinkulu ze-VGA + 2 USB kuphaneli engemuva. Kuphaneli engemuva ungathola futhi imbobo ye-IPMI, ebhalwe ukuthi MGMT, kanye nembobo ye-RJ-45 COM, ebhalwe ukuthi IOIOI.
Ukusetha kokuqala
Ngesikhathi sokusetha kokuqala, ushintsha izilungiselelo zokungena ze-BIOS futhi ulungiselele i-IPMI. I-Huawei ikhuthaza ukuphepha, ngakho-ke i-BIOS ne-IPMI zivikelwe ngamaphasiwedi ahlukile kunamaphasiwedi avamile okuphatha/omlawuli. Lapho uqala ukungena, i-BIOS ikuxwayisa ukuthi iphasiwedi ezenzakalelayo ibuthakathaka futhi idinga ukushintshwa.
I-Huawei BIOS Setup Utility iyafana kusixhumi esibonakalayo se-Aptio Setup Utility, esetshenziswa kumaseva e-SuperMicro. Lapha ngeke uthole ukushintshwa kobuchwepheshe be-Hyper-Threading noma imodi ye-Legacy.
I-interface yewebhu yemojuli ye-BMC inikezela ngezinkambu zokufaka ezintathu esikhundleni sezibili ezilindelekile. Ungangena kusixhumi esibonakalayo usebenzisa igama lokungena lendawo noma ukufakazela ubuqiniso ngeseva eyirimothi ye-LDAP.
I-IPMI inikeza izinketho eziningi zokuphatha iseva:
- I-RMCP;
- I-RMCP+;
- I-VNC;
- I-KVM;
- I-SNMP.
Ngokuzenzakalelayo, indlela ye-RMCP esetshenziswa ku-ipmitool ivaliwe ngenxa yezizathu zokuphepha. Ukufinyelela kwe-KVM, i-iBMC inikeza izixazululo ezimbili:
- "yakudala" Java applet;
- I-HTML5 console.
Njengoba ama-ARM processors abekwe njengawonga amandla, ekhasini eliyinhloko le-interface yewebhu ye-iBMC ungabona ibhulokhi ethi "Energy Efficiency", engabonisi nje kuphela ukuthi angakanani amandla esiwalondolozile sisebenzisa le seva, kodwa mangaki amakhilogremu e-carbon dioxide ayengekho. ikhishwe emkhathini.
Ngaphandle kwamandla amangalisayo okunikezwa kwamandla, kwimodi yokungenzi lutho iseva iyasebenzisa Ama-watt ayi-340, futhi ngaphansi komthwalo ogcwele kuphela Ama-watt ayi-440.
Sebenzisa
Isinyathelo esilandelayo esibalulekile ukufaka isistimu yokusebenza. Kukhona ukusatshalaliswa kweLinux okuningi okudumile kwezakhiwo ze-arm64, kodwa yizinguqulo zesimanje kuphela ezifaka futhi zisebenze ngendlela efanele kuseva. Nalu uhlu lwezinhlelo zokusebenza esikwazile ukuzisebenzisa:
