Lero ndikuwuzani momwe mungakonzekere maukonde muofesi yaying'ono yamakampani. Tafika pamlingo wina mu maphunziro operekedwa ku ma switch - lero tikhala ndi kanema womaliza, pomaliza mutu wa kusintha kwa Cisco. Zachidziwikire, tibwereranso ku masinthidwe, ndipo mu phunziro lotsatira la kanema ndikuwonetsani mapu amsewu kuti aliyense amvetsetse njira yomwe tikuyenda komanso gawo la maphunziro omwe taphunzira kale.
Tsiku la 18 la makalasi athu lidzakhala chiyambi cha mutu watsopano woperekedwa kwa ma routers, ndipo ndipereka phunziro lotsatira, Tsiku la 17, ku ndemanga yowunikira pamitu yophunziridwa ndikuyankhula za mapulani owonjezera maphunziro. Tisanalowe mumutu wa phunziro la lero, ndikufuna kuti mukumbukire kugawana makanemawa, lembani ku njira yathu ya YouTube, pitani pagulu lathu la Facebook ndi tsamba lathu. , komwe mungapeze zolengeza za maphunziro atsopano.
Ndiye tiyeni tiyambe kupanga network network. Ngati mugawa izi m'magawo, chinthu choyamba muyenera kuchita ndikuzindikira zofunikira zomwe netiweki iyi iyenera kukwaniritsa. Chifukwa chake musanayambe kupanga netiweki yaofesi yaying'ono, netiweki yakunyumba kapena netiweki ina iliyonse yapafupi, muyenera kulemba mndandanda wazomwe mukufuna.
Chinthu chachiwiri choti muchite ndikupanga mapangidwe amtundu, kusankha momwe mukukonzekera kukwaniritsa zofunikira, ndipo chachitatu ndikupanga kasinthidwe ka intaneti.
Tiyerekeze kuti tikukamba za ofesi yatsopano yomwe muli madipatimenti osiyanasiyana: Dipatimenti yotsatsa malonda, dipatimenti yoyang'anira kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake . Chotsatira ndi chipinda cha dipatimenti Yogulitsa.
Zofunikira pamaneti opangidwira ndikuti ogwira ntchito m'madipatimenti osiyanasiyana sayenera kulumikizidwa wina ndi mnzake. Izi zikutanthauza kuti, mwachitsanzo, ogwira ntchito ku dipatimenti yogulitsa malonda omwe ali ndi makompyuta 7 amatha kusinthana mafayilo ndi mauthenga wina ndi mzake pa intaneti. Mofananamo, makompyuta awiri mu dipatimenti yotsatsa malonda amatha kulankhulana wina ndi mzake. Dipatimenti yoyang'anira, yomwe ili ndi kompyuta imodzi, ikhoza kukulirakulira mpaka antchito angapo mtsogolo. Momwemonso, dipatimenti yowerengera ndalama ndi dipatimenti yowona za anthu ayenera kukhala ndi maukonde awoawo.
Izi ndi zofunika pa network yathu. Monga ndanenera, chipinda cha seva ndi chipinda chomwe mungakhalemo komanso momwe mungathandizire maukonde onse aofesi. Popeza iyi ndi netiweki yatsopano, ndinu omasuka kusankha kasinthidwe kake ndi momwe mungakonzekere. Tisanapitilize, ndikufuna ndikuwonetseni momwe chipinda cha seva chimawonekera.
Zili ndi inu, monga woyang'anira netiweki, ngati chipinda chanu cha seva chidzawoneka ngati chomwe chikuwonetsedwa pa slide yoyamba kapena chomwe chawonetsedwa pa chachiwiri.
Kusiyana pakati pa ma seva awiriwa kumadalira momwe mumalangira. Ngati mutsatira mchitidwe wolemba zingwe za netiweki zokhala ndi ma tag ndi zomata, mutha kusunga netiweki yanu yaofesi. Monga mukuonera, mu chipinda chachiwiri cha seva zingwe zonse zili mu dongosolo ndipo gulu lililonse la zingwe lili ndi tag yosonyeza kumene zingwezi zimapita. Mwachitsanzo, chingwe chimodzi chimapita ku dipatimenti yogulitsa malonda, china kwa olamulira, ndi zina zotero, ndiko kuti, chirichonse chimadziwika.
Mukhoza kupanga chipinda cha seva monga momwe zasonyezedwera pa slide yoyamba ngati muli ndi makompyuta 10 okha. Mutha kumata zingwe mwachisawawa ndikukonza zosintha mwanjira ina popanda dongosolo lililonse. Ili si vuto bola muli ndi netiweki yaying'ono. Koma makompyuta ochulukirapo akawonjezeredwa komanso maukonde akampani akukulirakulira, pafika nthawi yomwe mudzawonongera nthawi yanu yambiri mukuzindikira zingwe zonsezo. Mutha kudula chingwe mwangozi kupita pakompyuta kapena osamvetsetsa kuti ndi chingwe chiti chomwe chalumikizidwa ndi doko liti.
Chifukwa chake, kulinganiza mwanzeru kakonzedwe ka zida m'chipinda chanu cha seva ndikofunikira kwambiri. Chotsatira chofunikira chokambirana ndi chitukuko cha maukonde - zingwe, mapulagi ndi ma sockets. Tinakambirana zambiri za masiwichi, koma ndinayiwala kulankhula za zingwe.
Chingwe cha CAT5 kapena CAT6 nthawi zambiri chimatchedwa kuti chopotoka chosatetezedwa kapena chingwe cha UTP. Mukachotsa chingwe chotetezera cha chingwe choterocho, mudzawona mawaya 8 opotoka awiriawiri: obiriwira ndi oyera-wobiriwira, malalanje ndi oyera-lalanje, a bulauni ndi oyera-bulauni, abuluu ndi oyera-buluu. Nβchifukwa chiyani amapotozedwa? Kusokoneza kwa ma electromagnetic kwa ma siginecha amagetsi mu mawaya awiri ofanana kumapangitsa phokoso, zomwe zimapangitsa kuti chizindikirocho chifooke pomwe mawaya akuchulukirachulukira. Kupotoza mawayawo kumathandizirana chifukwa cha mafunde opangidwa, kumachepetsa kusokoneza ndikuwonjezera mtunda wotumizira ma siginecha.
Tili ndi magulu a 6 a chingwe cha intaneti - kuchokera ku 1 mpaka 6. Pamene gulu likuwonjezeka, mtunda wotumizira chizindikiro ukuwonjezeka, makamaka chifukwa chakuti kuchuluka kwa kupotoza kwa awiriawiri kumawonjezeka. Chingwe cha CAT6 chimakhala ndi matembenuzidwe ochulukirapo pautali wagawo kuposa CAT5, chifukwa chake ndichokwera mtengo kwambiri. Chifukwa chake, zingwe za Gulu 6 zimapereka kuthamanga kwapa data pamtunda wautali. Magulu odziwika bwino a chingwe pamsika ndi 5, 5e ndi 6. Chingwe cha 5e ndi gulu lotukuka la 5, limagwiritsidwa ntchito ndi makampani ambiri, koma popanga maukonde amakono aofesi amagwiritsa ntchito kwambiri CAT6.
Mukavula chingwechi mchimake chidzakhala ndi mapeyala 4 opindika monga momwe zasonyezedwera pa slide. Mulinso ndi cholumikizira cha RJ-45 chomwe chili ndi zikhomo 8 zachitsulo. Muyenera kuyika mawaya a chingwe mu cholumikizira ndikugwiritsa ntchito chida cha crimping chotchedwa crimper. Kuti muchepetse mawaya opotoka, muyenera kudziwa momwe mungawakhazikitsire bwino mu cholumikizira. Njira zotsatirazi zimagwiritsidwa ntchito pa izi.
Pali mwachindunji ndi crossover, kapena crossover crimping wa zingwe zopotoka. Choyamba, mumagwirizanitsa mawaya amtundu womwewo kwa wina ndi mzake, ndiye kuti, mumagwirizanitsa waya woyera-lalanje ndi pini 1 ya cholumikizira cha RJ-45, lalanje mpaka chachiwiri, waya wobiriwira-wobiriwira chachitatu ndi zina zotero, monga momwe tawonetsera mβchithunzichi.
Kawirikawiri, ngati mutagwirizanitsa zipangizo 2 zosiyana, mwachitsanzo, chosinthira ndi hub kapena kusinthana ndi rauta, mumagwiritsa ntchito crimping mwachindunji. Ngati mukufuna kulumikiza zipangizo zofanana, mwachitsanzo kusinthana ndi kusintha kwina, muyenera kugwiritsa ntchito crossover. Pazochitika zonsezi, waya wamtundu womwewo umalumikizidwa ndi waya wamtundu womwewo; mumangosintha malo omwe ali ndi mawaya ndi zikhomo zolumikizira.
Kuti mumvetse izi, ganizirani za foni. Mumalankhula mu maikolofoni ya foni ndikumvetsera mawu kuchokera kwa wokamba nkhani. Ngati mukulankhula ndi bwenzi lanu, zomwe mumalankhula mu maikolofoni zimabwera kudzera mu sipika ya foni yake, ndipo zomwe mnzanu amalankhula mu maikolofoni yake zimatuluka mu sipika yanu.
Izi ndi zomwe kugwirizana kwa crossover kuli. Mukalumikiza maikolofoni anu palimodzi ndikulumikizanso masipika anu, mafoni sagwira ntchito. Uku sikufanizira bwino kwambiri, koma ndikuyembekeza kuti mupeza lingaliro la crossover: waya wolandila amapita ku waya wotumizira, ndipo waya wotumizira amapita kwa wolandila.
Kulumikizana mwachindunji kwa zida zosiyanasiyana kumagwira ntchito motere: chosinthira ndi rauta zili ndi madoko osiyanasiyana, ndipo ngati zikhomo 1 ndi 2 zosinthira zimapangidwira kufalitsa, ndiye kuti zikhomo 1 ndi 2 za rauta zimapangidwira kulandira. Ngati zida zili zofanana, ndiye kuti zolumikizira 1 ndi 2 za masiwichi oyamba ndi achiwiri zimagwiritsidwa ntchito pofalitsa, ndipo popeza mawaya opatsirana sangathe kulumikizidwa ndi mawaya omwewo, kulumikizana 1 ndi 2 kwa chosinthira choyamba kumalumikizidwa olumikizana 3 ndi 6 wa switch yachiwiri, ndiye kuti, ndi wolandila. Ndicho chimene crossover ndi yake.
Koma lero ndondomekozi ndi zachikale, m'malo mwake Auto-MDIX imagwiritsidwa ntchito - mawonekedwe osinthira deta omwe amadalira chilengedwe. Mutha kudziwa za izi kuchokera ku Google kapena nkhani ya Wikipedia, sindikufuna kutaya nthawi pa izi. Mwachidule, mawonekedwe amagetsi ndi makinawa amakulolani kugwiritsa ntchito chingwe chilichonse, monga kugwirizana kwachindunji, ndipo chipangizo chanzeru chokha chidzadziwa mtundu wa chingwe chomwe chikugwiritsidwa ntchito - chotumizira kapena cholandila, ndikuchigwirizanitsa moyenerera.
Tsopano popeza tawona momwe zingwe zimafunikira kulumikizidwa, tiyeni tipitirire pazofunikira pakupanga maukonde. Tiyeni titsegule Cisco Packet Tracer ndikuwona kuti ndayika chithunzi cha ofesi yathu ngati gawo lapamwamba la chitukuko cha maukonde. Popeza madipatimenti osiyanasiyana ali ndi maukonde osiyanasiyana, ndi bwino kuwakonza kuchokera ku masiwichi odziyimira pawokha. Ndiyika chosinthira chimodzi mchipinda chilichonse, kotero tili ndi masiwichi asanu ndi limodzi kuchokera pa SW0 kupita ku SW5. Kenako ndidzakonza kompyuta imodzi kwa wogwira ntchito muofesi aliyense - zidutswa 1 kuchokera ku PC12 mpaka PC0. Pambuyo pake, ndikulumikiza kompyuta iliyonse ku chosinthira pogwiritsa ntchito chingwe. Dongosololi ndi lotetezeka, zambiri za dipatimenti ina sizipezeka ku dipatimenti ina, simukudziwa za kupambana kapena kulephera kwa dipatimenti ina, ndipo ndi mfundo zaofesi yabwino. Mwina wina mu dipatimenti yogulitsa ali ndi luso lobera ndipo atha kulowa m'makompyuta a dipatimenti yotsatsa pa intaneti ndikuchotsa zidziwitso, kapena anthu m'madipatimenti osiyanasiyana sayenera kugawana zambiri pazifukwa zamabizinesi, ndi zina zotero, kotero maukonde osiyana amathandizira kupewa milandu yofananira. .
Vuto ndi ili. Ndiwonjeza mtambo pansi pa chithunzicho - iyi ndi intaneti, yomwe kompyuta ya woyang'anira maukonde mu chipinda cha seva imalumikizidwa kudzera pa switch.
Simungathe kupatsa dipatimenti iliyonse mwayi wopezeka pa intaneti, chifukwa chake muyenera kulumikiza masiwichi a dipatimenti ku chosinthira muchipinda cha seva. Izi ndizomwe zimafunikira pakulumikiza ofesi ya intaneti - zida zonse payekha ziyenera kulumikizidwa ndi chosinthira wamba chomwe chimatha kupeza kunja kwa netiweki yamaofesi.
Pano tili ndi vuto lodziwika bwino: ngati tisiya maukonde ndi zoikamo zosasintha, makompyuta onse adzatha kulankhulana wina ndi mzake chifukwa adzakhala olumikizidwa kwa VLAN1 mbadwa yomweyo. Kuti tipewe izi, tifunika kupanga ma VLAN osiyanasiyana.
Tidzagwira ntchito ndi netiweki ya 192.168.1.0/24, yomwe tidzagawanitsa ma subnets angapo ang'onoang'ono. Tiyeni tiyambe ndi kupanga mawu netiweki VLAN10 ndi malo adilesi 192.168.1.0/26. Mutha kuyang'ana patebulo mum'modzi mwamaphunziro akanema am'mbuyomu ndikundiuza kuchuluka kwa makamu omwe adzakhale pa netiweki iyi - / 26 amatanthauza ma bits awiri obwereka omwe amagawa maukonde m'magawo anayi a ma adilesi 2, kotero padzakhala 4 IP yaulere. ma adilesi mu subnet yanu ya omwe akulandira. Tiyenera kupanga netiweki yosiyana yolumikizirana mawu kuti tilekanitse kulumikizana kwamawu ndi kulumikizana kwa data. Izi zikuyenera kuchitidwa kuti aletse wowukirayo kuti asalumikizane ndikulankhula pafoni ndikugwiritsa ntchito Wireshark kuti alembe zomwe zimatumizidwa panjira yomweyi ngati kulumikizana ndi mawu.
Chifukwa chake, VLAN10 idzagwiritsidwa ntchito pa telefoni ya IP yokha. Slash 26 ikutanthauza kuti mafoni 62 atha kulumikizidwa ndi netiweki iyi. Kenako, tidzapanga maukonde a dipatimenti yoyang'anira VLAN20 yokhala ndi adilesi ya 192.168.1.64/27, ndiko kuti, ma adilesi a netiweki adzakhala 32 okhala ndi ma adilesi 30 ovomerezeka a IP. VLAN30 iperekedwa ku dipatimenti yotsatsa, VLAN40 ikhala dipatimenti yogulitsa, VLAN50 idzakhala dipatimenti yazachuma, VLAN60 idzakhala dipatimenti ya HR, ndipo VLAN100 idzakhala network ya IT department.
Tiyeni tilembe maukondewa mu chithunzi cha topology network yaofesi ndikuyamba ndi VLAN20 chifukwa VLAN10 idasungidwira telefoni. Pambuyo pake, tikhoza kuganiza kuti tapanga mapangidwe a maofesi atsopano.
Ngati mukukumbukira, ndinanena kuti chipinda chanu cha seva chikhoza kukhala ndi dongosolo lachisokonezo kapena kukonzekera mosamala. Mulimonsemo, muyenera kupanga zolemba - izi zitha kukhala zolemba pamapepala kapena pakompyuta, zomwe zidzalembe mawonekedwe a maukonde anu, kufotokoza ma subnets onse, maulumikizidwe, ma adilesi a IP ndi zidziwitso zina zofunika pa ntchito ya woyang'anira maukonde. Pamenepa, pamene netiweki ikukula, mudzakhala mukuwongolera zinthu nthawi zonse. Izi zikuthandizani kuti musunge nthawi ndikupewa zovuta mukalumikiza zida zatsopano ndikupanga ma subnets atsopano.
Kotero, titatha kupanga ma subnets osiyana pa dipatimenti iliyonse, ndiko kuti, tapanga kuti zipangizo zizitha kuyankhulana mkati mwa VLAN yawo, funso lotsatira likubwera. Monga mukukumbukira, chosinthira mu chipinda cha seva ndi cholumikizira chapakati chomwe masiwichi ena onse amalumikizidwa, chifukwa chake ayenera kudziwa za maukonde onse muofesi. Komabe, kusintha SW0 kumangofunika kudziwa za VLAN30 chifukwa palibe maukonde ena mu dipatimentiyi. Tsopano taganizirani kuti dipatimenti yathu yogulitsa malonda yakula ndipo tidzayenera kusamutsa antchito ena kumalo a dipatimenti yotsatsa malonda. Pankhaniyi, tidzafunika kupanga netiweki ya VLAN40 mu dipatimenti yotsatsa, yomwe iyeneranso kulumikizidwa ndi switch ya SW0.
Mu imodzi mwa mavidiyo apitawo, tinakambirana zomwe zimatchedwa kasamalidwe ka mawonekedwe, ndiko kuti, tinapita ku mawonekedwe a VLAN1 ndikuyika adilesi ya IP. Tsopano tifunika kukonza makompyuta a dipatimenti yoyang'anira 2 kuti agwirizane ndi madoko olowa a switch omwe amagwirizana ndi VLAN30.
Tiyeni tiwone kompyuta yanu ya PC7, komwe inu, monga woyang'anira maukonde, muyenera kuyang'anira patali masiwichi onse a netiweki. Njira imodzi yotsimikizira izi ndikupita ku dipatimenti yoyang'anira ndikukonza pamanja switch ya SW0 kuti ilumikizane ndi kompyuta yanu. Komabe, muyenera kusintha masinthidwe akutali chifukwa masinthidwe atsamba sizotheka nthawi zonse. Koma muli pa VLAN100 chifukwa PC7 yolumikizidwa ndi VLAN100 switch port.
Kusintha SW0 sadziwa kalikonse za VLAN100, kotero tiyenera perekani VLAN100 ku limodzi la madoko ake kuti PC7 kulankhula nawo. Ngati mupereka adilesi ya IP ya VLAN30 kuti igwirizane ndi SW0, ndi PC0 ndi PC1 yokha yomwe ingalumikizane nayo. Komabe, muyenera kuyang'anira kusinthaku kuchokera pa kompyuta yanu ya PC7 ya VLAN100 network. Chifukwa chake, tiyenera kupanga mawonekedwe a VLAN0 mu switch SW100. Tiyenera kuchita chimodzimodzi ndi zotsalira zotsalira - zipangizo zonsezi ziyenera kukhala ndi mawonekedwe a VLAN100, omwe tiyenera kupereka ma adilesi a IP kuchokera pamaadiresi omwe amagwiritsidwa ntchito ndi PC7. Adilesiyi imatengedwa kuchokera ku 192.168.1.224/27 mndandanda wa IT VLAN ndipo imaperekedwa ku ma doko onse omwe VLAN100 imaperekedwa.
Pambuyo pake, kuchokera ku chipinda cha seva, kuchokera pa kompyuta yanu, mudzatha kulumikizana ndi zosintha zilizonse kudzera pa protocol ya Telnet ndikuzikonza motsatira zofunikira za intaneti. Komabe, monga woyang'anira ma netiweki, mumafunikanso mwayi wopeza masiwichi kudzera panjira yolumikizirana yakunja, kapena osalumikizana ndi gulu. Kuti mupereke mwayi wotere, mukufunikira chipangizo chotchedwa Terminal Server, kapena seva yotsiriza.
Malinga ndi logic network topology, masiwichi onsewa ali m'zipinda zosiyanasiyana, koma mwakuthupi amatha kukhazikitsidwa pa rack wamba mu chipinda cha seva. Mutha kuyika seva yomaliza mu rack yomweyi, pomwe makompyuta onse adzalumikizidwa. Zingwe zowoneka bwino zimatuluka mu seva iyi, pamapeto pake pomwe pali cholumikizira cha seri, ndipo pamapeto pake pali pulagi yanthawi zonse ya chingwe cha CAT5. Zingwe zonsezi zimalumikizidwa ndi ma doko a console a masiwichi omwe amayikidwa mu rack. Chingwe chilichonse chowala chimatha kulumikiza zida 8. Seva yotsirizayi iyenera kulumikizidwa ndi kompyuta yanu ya PC7. Chifukwa chake, kudzera pa Terminal Server mutha kulumikizana ndi doko la zosinthira zilizonse kudzera panjira yolumikizirana yakunja.
Mutha kufunsa chifukwa chake izi ndizofunikira ngati zida zonsezi zili pafupi ndi inu muchipinda chimodzi cha seva. Chowonadi ndichakuti kompyuta yanu imatha kulumikizana mwachindunji ndi doko limodzi la console. Chifukwa chake, kuti muyese masiwichi angapo, muyenera kutulutsa chingwe kuchokera ku chipangizo chimodzi kuti mulumikizane ndi china. Mukamagwiritsa ntchito seva yomaliza, mumangofunika kukanikiza kiyi imodzi pa kiyibodi ya pakompyuta yanu kuti mulumikizane ndi doko la switch #0, kuti musinthe kusinthana kwina muyenera kukanikiza kiyi ina, ndi zina zotero. Chifukwa chake, mutha kuwongolera masiwichi aliwonse mwa kukanikiza makiyi. Chifukwa chake, muzochitika zabwinobwino, mumafunika seva yomaliza kuti muzitha kuyang'anira ma switch mukathana ndi vuto la netiweki.
Chifukwa chake, tamaliza ndi mapangidwe a netiweki ndipo tsopano tiwona zosintha zoyambira pamaneti.
Chida chilichonse chiyenera kupatsidwa dzina la alendo, zomwe muyenera kuchita pogwiritsa ntchito mzere wolamula. Ndichiyembekezo changa kuti pamene mukumaliza maphunzirowa, mudzapeza chidziwitso chothandiza kuti mudziwe ndi mtima malamulo ofunikira kuti mupereke dzina la alendo, kupanga chikwangwani cholandirira, kukhazikitsa mawu achinsinsi, kukhazikitsa mawu achinsinsi a Telnet, ndikuyambitsa mawu achinsinsi. . Muyenera kudziwa momwe mungasamalire adilesi ya IP yosinthira, kugawa chipata chokhazikika, kuletsa chipangizocho, kuyika malamulo oletsa, ndikusunga zosintha zomwe zasinthidwa.
Mukamaliza masitepe onse atatu: dziwani zofunikira pa intaneti, jambulani chithunzi cha maukonde amtsogolo osachepera pamapepala ndikusunthira ku zoikamo, mutha kukonza chipinda chanu cha seva.
Monga ndanenera kale, tatsala pang'ono kumaliza kuphunzira masiwichi, ngakhale tibwerera kwa iwo, ndiye mumaphunziro otsatirawa avidiyo tidzapita ku ma routers. Uwu ndi mutu wosangalatsa kwambiri, womwe ndiyesera kuufotokoza mokwanira momwe ndingathere. Tidzawona kanema woyamba wokhudza ma routers kudzera mu phunziro, ndipo phunziro lotsatira, Tsiku la 17, ndidzapereka zotsatira za ntchito yomwe yachitika pophunzira maphunziro a CCNA, ndikuwuzani gawo la maphunziro omwe mwaphunzira kale. ndi kuchuluka komwe mukuyenerabe kuphunzira, kuti aliyense amvetse bwino lomwe gawo la maphunziro lomwe adafika.
Ndikukonzekera kutumiza mayeso oyeserera patsamba lathu posachedwa, ndipo ngati mungalembetse, mudzatha kuyesa mayeso ofanana ndi omwe mungatenge kuti mutenge mayeso a CCNA.
Zikomo chifukwa chokhala nafe. Kodi mumakonda zolemba zathu? Mukufuna kuwona zambiri zosangalatsa? Tithandizeni potipatsa oda kapena kulimbikitsa anzathu, 30% kuchotsera kwa ogwiritsa ntchito a Habr pa analogi yapadera yamaseva olowera, omwe tinapangira inu: (ikupezeka ndi RAID1 ndi RAID10, mpaka 24 cores mpaka 40GB DDR4).
