Namuhla etafuleni lethu sineseva entsha yesizukulwane sesihlanu ye-Cisco UCS C240 rack.
Yini eyenza le seva ethile ye-Cisco ibe mnandi ngoku-unboxing, njengoba sesivele sibhekene nesizukulwane sayo sesihlanu?
Okokuqala, amaseva e-Cisco manje asekela isizukulwane sakamuva se-Intel Scalable processors yesizukulwane sesibili. Okwesibili, manje usungakwazi ukufaka amamojula we-Optane Memory ukuze usebenzise amadrayivu amaningi e-NVMe.
Imibuzo enengqondo iyaphakama: ingabe amaseva avela kwabanye abathengisi abakwenzi lokhu? Yini enkulu, njengoba iseva ye-x86 nje? Izinto zokuqala kuqala.
Ngaphezu kwemisebenzi yeseva emele yodwa, i-Cisco C240 M5 ingaba yingxenye yezakhiwo zeCisco UCS. Lapha sikhuluma ngokuxhuma ku-FI nokuphatha ngokugcwele amaseva usebenzisa i-UCS Manager, kuhlanganise ne-Auto Deploy.
Ngakho-ke, phambi kwethu sineseva ye-Cisco "yensimbi", isizukulwane sayo sesihlanu, iminyaka engaphezu kwe-10 emakethe.
Manje sizobuyela ezintweni eziyisisekelo, khumbula ukuthi yiziphi izingxenye zeseva, futhi yini eyenza i-Cisco C240 M5 ingabi nje yesimanje, kodwa ithuthuke ngempela.
Ake sibheke ukuthi yini efakwe ephaketheni.
Okuqukethwe Kwebhokisi: iseva, i-KVM Dongle, imibhalo, idiski, izintambo zamandla ezi-2, ikhithi yokufaka.
Susa ikhava. Chofoza, hambisa futhi yilokho. Awekho ama-screwdrivers noma ama-bolt alahlekile.
Amalebula aluhlaza abamba iso lakho ngokushesha. Zonke izici ezisekela ukushintshashintsha okushisayo zinazo. Isibonelo, ungashintsha abalandeli kalula ngaphandle kokucisha amandla kuso sonke iseva.
Siphinde sibone ama-radiator amakhulu, lapho ama-Intel Scal 2 Gen processors afihlwa ngaphansi kwawo. Qaphela ukuthi lokhu kufika kuma-cores angama-56 ngeseva ye-2U ngayinye ngaphandle kwezinkinga zokupholisa. Imemori eyengeziwe eyengeziwe iyasekelwa, kufika ku-1TB ngephrosesa ngayinye. Imvamisa yenkumbulo esekelwayo ikhuphuke yafinyelela ku-2933 MHz.
Eduze kwe-CPU sibona izikhala ezingu-24 ze-RAM - ungasebenzisa izinti ezifika ku-128 GB noma imemori ye-Intel Optane efika ku-512 GB slot.
I-Intel Optane ivula isivinini sokucubungula esimangalisayo. Isibonelo, ingasetshenziswa njengedrayivu yasendaweni ye-SSD eshesha kakhulu.
Manje izicelo ezengeziwe ezivela kumakhasimende ziqala ngamagama athi: “Ngifuna amadiski amaningi, amadrayivu e-NVMe amaningi ohlelweni olulodwa.”
Ngaphambili sibona izikhala ezingu-8 2.5 inch zamadrayivu. Inketho yesikhulumi enezikhala ezijwayelekile ezingama-24 kusuka kuphaneli yangaphambili nayo iyatholakala ukuze i-oda.
Kuye ngokuguqulwa, amadrayivu e-NMVe angafika kwangu-8 ku-U.2 form factor angafakwa ezindaweni zokuqala.
I-C240 platform ivame ukuthandwa kakhulu ngamakhasimende amakhulu wedatha. Isicelo sabo esiyinhloko yikhono lokuba namadrayivu ebhuthi yasendaweni futhi okungcono axhumeke kuwo.
Ephendula lesi sicelo, iCisco inqume ukwengeza izikhala ezimbili zamadiski ashintshwayo ashisayo ngemuva kweseva ku-C240 M5.
Atholakala kwesokudla sezikhala zokunwetshwa kwamandla kagesi. Amadrayivu angaba yinoma iyiphi: SAS, SATA, SSD, NVMe.
Eduze sibona amandla kagesi angu-1600W. Ziyakwazi futhi i-Hot Pluggable futhi ziza namathegi aluhlaza.
Ukuze usebenze ne-subsystem yediski, ungafaka isilawuli se-RAID esivela ku-LSI esino-2 GB wenqolobane, noma ikhadi le-HBA lokudlulisela phambili okuqondile, endaweni ezinikele.
Isibonelo, le ndlela isetshenziswa lapho kwakhiwa isixazululo se-Cisco HyperFlex hyperconverged.
Kunolunye uhlobo lwekhasimende olungawadingi nhlobo amadiski. Abafuni ukufaka sonke isilawuli se-RAID ngaphansi kwe-hypervisor, kodwa bathanda icala le-2U ngokuya ngesevisi kalula.
I-Cisco nayo inesixazululo kubo.
Sethula imojuli yeFlexFlash:
Amakhadi amabili e-SD, afinyelela ku-128 GB, anokusekelwa kwesibuko, ukufaka i-hypervisor, isibonelo, i-VMware ESXi. Yile nketho thina kwa-ITGLOBAL.COM esiyisebenzisayo lapho sakha amasayithi ethu emhlabeni jikelele.
Kulawo makhasimende adinga isikhala esiningi sokulayisha i-OS, kukhona inketho yemojula yamadrayivu amabili e-SSD "satash" ngefomethi ye-M.2, enomthamo we-240 noma 960 GB ngayinye. Okuzenzakalelayo yi-software ye-RAID.
Kumadrayivu angu-240 GB, kunenketho yokusebenzisa isilawuli se-Cisco Boot esilungiselelwe i-M.2 Raid - isilawuli esihlukile se-RAID yehadiwe kulawa madrayivu amabili e-SSD.
Konke lokhu kusekelwa yizo zonke izinhlelo zokusebenza: i-VMware neWindows, kanye nezinhlelo zokusebenza zeLinux ezahlukahlukene.
Inombolo yezikhala ze-PCI yi-6, okuyinto evamile yesikhulumi se-2U.
Kunesikhala esiningi ngaphakathi. Kulula ukufaka ama-accelerator amabili agcwele agcwele avela ku-NVidia kumaseva, isibonelo, i-TESLA M10 kumaphrojekthi wokusebenzisa amadeskithophu abonakalayo noma uhlelo lwakamuva lwe-V100 ku-32GB lwemisebenzi yobuhlakani bokwenziwa. Sizoyisebenzisa ku-unboxing elandelayo.
Isimo samachweba simi kanje:
- Imbobo yekhonsoli;
- Ichweba lokuphatha elizinikele le-Gigabit;
- Izimbobo ezimbili ze-USB 3.0;
- Ikhadi lenethiwekhi elihlanganisiwe le-2-port Intel x550 10Gb BASE-T;
- Ikhadi le-mLOM ozikhethela lona, i-adaptha ye-Cisco Vic 1387 dual-port 40 GB.
Imbobo ye-mLOM ingamukela kuphela amakhadi e-Cisco VIC, asebenza kahle ekuthumeleni kokubili ithrafikhi ye-LAN ne-SAN. Uma usebenzisa iseva njengengxenye yendwangu ye-Cisco UCS, le ndlela ikuvumela ukuthi uhlele ukuxhumeka kumanethiwekhi e-LAN ne-SAN ngendlela ebumbene ngaphandle kwesidingo sokusebenzisa i-adaptha ye-fc ehlukile.
Masifake isisheshisi sevidiyo se-Nvidia V100. Sikhipha isikhuphukeli sesibili, sikhipha ipulaki, sifaka ikhadi ku-slot ye-PCI, sivale ipulasitiki bese sivala. Sixhuma amandla engeziwe. Okokuqala ekhadini, bese kuba isikhuphukeli. Sibeka isikhuphukeli endaweni. Ngokuvamile, yonke into ihamba ngaphandle kokusetshenziswa kwezikulufa nezando. Ngokushesha futhi kucacile.
Kwenye yezinto ezilandelayo sizobonisa ukufakwa kwayo kokuqala.
Sikulungele futhi ukuphendula yonke imibuzo noma kumazwana.
