Iiseva ezineprosesa ezisekwe kuyilo lwe-arm64 zingena ngenkuthalo ebomini bethu. Kweli nqaku siza kukubonisa i-unboxing, ufakelo kunye novavanyo olufutshane lweseva entsha ye-TaiShan 2280v2.
Kukhutshwa
Umncedisi ufikile kuthi kwibhokisi engabonakaliyo. Amacala ebhokisi ane logo yeHuawei, kunye nesikhongozeli kunye namanqaku okupakisha. Phezulu ungabona imiyalelo yendlela yokususa ngokufanelekileyo umncedisi kwibhokisi. Masiqalise ukukhupha izinto!
Umncedisi usongelwe kumaleko we-antistatic kwaye ubekwe phakathi kweeleya ze-foam. Ngokubanzi, ukupakishwa okusemgangathweni komncedisi.
Kwibhokisi encinci unokufumana isilayidi, iibholiti ezimbini kunye neentambo zamandla zeSchuko-C13 ezimbini. Isileyi sibonakala silula ngokwaneleyo, kodwa siza kuthetha ngaloo nto kamva.
Phezulu komncedisi lulwazi malunga nalo mncedisi, kunye nokufikelela kwimodyuli ye-BMC kunye ne-BIOS. Inombolo ye-serial imelwe yi-barcode-dimensional one-dimensional, kwaye ikhowudi ye-QR iqulethe ikhonkco kwindawo yenkxaso yobugcisa.
Masisuse isiciko somncedisi kwaye sijonge ngaphakathi.
Yintoni ngaphakathi?
Isigqubuthelo somncedisi sibanjwe kwindawo ethile nge-latch ekhethekileyo, enokuthi igcinwe kwindawo evaliweyo kunye ne-screwdriver ye-Phillips. Ukuvula i-latch kubangela ukuba i-cover cover isilayidi, emva koko ikhava inokususwa ngaphandle kweengxaki.
Umncedisi uza kuqwalaselo olwenziwayo olubizwa ngokuba I-TaiShan 2280 V2 512G Uqwalaselo olusemgangathweni kolu lungelelwaniso lulandelayo:
- I-2x Kunpeng 920 (i-ARM64 i-architecture, i-64 cores, i-frequency frequency 2.6 GHz);
- I-16x DDR4-2933 32GB (i-512 GB iyonke);
- 12x SAS HDD 1200GB;
- umlawuli we-RAID we-hardware i-Avago 3508 kunye nokunikezelwa kwamandla okugcina ngokusekelwe kwi-ionistor;
- Ikhadi lenethiwekhi ye-2x enezibuko ezine ze-1GE;
- Ikhadi lenethiwekhi ye-2x ene-10GE / 25GE SFP + izibuko ezine;

- Ityala leRackmount 2U.
I-motherboard yeseva isebenzisa umgangatho we-PCI Express 4.0, okuvumela ukuba usebenzise amandla apheleleyo e-4x 25GE amakhadi womnatha.
Kuqwalaselo lomncedisi oluthunyelwe kuthi, iindawo zokubeka i-RAM eziyi-16 azinanto. Ngokwenyama, iprosesa ye-Kunpeng 920 isekela ukuya kwi-2 TB ye-RAM, ekuvumela ukuba ufake i-32 yememori ye-128 GB nganye, ukwandisa inani elipheleleyo le-RAM kwi-4 TB kwi-platform ye-hardware enye.
Iiprosesa zineeradiyetha ezisuswayo ngaphandle kwabalandeli babo. Ngokuchasene noko kulindelekileyo, iiprosesa zithengiswa kwi-motherboard (BGA) kwaye kwimeko yokusilela kunokutshintshwa kuphela kwiziko lenkonzo usebenzisa izixhobo ezikhethekileyo.
Ngoku masibuyisele iseva kunye kwaye siqhubele phambili ekufakeni i-rack.
Ukufakwa
Okokuqala, izilayidi zifakwe kwi-rack. Izilayidi ziishelufu ezilula apho iseva ibekwe khona. Ngakolunye uhlangothi, esi sisombululo silula kakhulu kwaye sifanelekile, kodwa akunakwenzeka ukuba sikhonze umncedisi ngaphandle kokuyisusa kwi-rack.
Xa kuthelekiswa nezinye iiseva, i-TaiShan itsala ingqalelo ngephaneli yayo yangaphambili ecaba kunye nombala oluhlaza nomnyama. Ngokwahlukileyo, ndingathanda ukuqaphela ukuba umenzi unovakalelo ekubhalweni kwezixhobo ezifakwe kwiseva. Umphathi ngamnye wediski uqulethe ulwazi oluyimfuneko malunga nediski efakiweyo, kwaye phantsi kwe-VGA port kukho i-icon ebonisa i-disk numbering order.
Izibuko le-VGA kunye nezibuko ezi-2 ze-USB kwiphaneli yangaphambili ziyibhonasi entle evela kumvelisi ukongeza kwi-VGA ephambili + 2 izibuko ze-USB kwiphaneli yangasemva. Kwiphaneli yangasemva unokufumana kwakhona i-IPMI port, ephawulwe i-MGMT, kunye ne-RJ-45 COM port, ephawulwe IOIOI.
Ukusekwa kokuqala
Ngethuba lokucwangcisa kokuqala, utshintsha izicwangciso zokungena kwi-BIOS kwaye uqwalasele i-IPMI. I-Huawei ikhuthaza ukhuseleko, ngoko ke i-BIOS kunye ne-IPMI zikhuselwe ngamaphasiwedi ahlukileyo kwi-admin/admin passwords eqhelekileyo. Xa ungena okokuqala, i-BIOS iyakulumkisa ukuba igama eliyimfihlo libuthathaka kwaye lifuna ukutshintshwa.
I-Huawei BIOS Setup Utility iyafana kwi-interface kwi-Aptio Setup Utility, esetyenziswa kwiiseva ze-SuperMicro. Apha awuyi kufumana iswitshi yetekhnoloji ye-Hyper-Threading okanye imo yeLifa.
Ujongano lwewebhu lwemodyuli ye-BMC lubonelela ngeendawo ezintathu zegalelo endaweni yezimbini ezilindelekileyo. Ungangena kujongano usebenzisa nokuba igama-gama lokugqithisa lasekuhlaleni okanye uqinisekiso ngeseva ekude ye-LDAP.
IPMI ibonelela ngeendlela ezininzi zolawulo lweseva:
- I-RMCP;
- I-RMCP+;
- VNC;
- KVM;
- I-SNMP
Ngokungagqibekanga, indlela ye-RMCP esetyenziswa kwi-ipmitool ivaliwe ngenxa yezizathu zokhuseleko. Ukufikelela kwe-KVM, i-iBMC ibonelela ngezisombululo ezibini:
- "yakudala" Java applet;
- HTML5 console.
Ekubeni iiprosesa ze-ARM zibekwe njengamandla asebenzayo, kwiphepha eliphambili le-interface ye-iBMC yewebhu unokubona ibhloko ethi "Energy Efficiency", ebonisa kungekuphela nje ukuba sisindise kangakanani amandla sisebenzisa lo mncedisi, kodwa zingaphi iikhilogram zekhabhoni dioxide. ikhutshelwe emoyeni.
Ngaphandle kwamandla anomtsalane obonelelo lwamandla, kwimowudi engasebenziyo iseva iyasebenzisa Ii-watt ezi-340, kwaye phantsi komthwalo opheleleyo kuphela Ii-watt ezi-440.
