Lero tikuyang'ana zida zatsopano, ndipo ndine wokondwa kwambiri kuti pazaka makumi ambiri za chitukuko cha makampani a seva, kwa nthawi yoyamba ndakhala ndikugwira chinachake chatsopano m'manja mwanga. Ichi si "chakale mu phukusi latsopano", ndi chipangizo chopangidwa kuchokera pachiyambi, chopanda chilichonse chofanana ndi omwe adayambitsa, ndipo ndi seva ya Edge yochokera ku Lenovo.
Sitinachitire mwina koma kugawana ndi Habr ndemanga yabwino kwambiri ya seva yathu, yomwe inali pa webusayiti ya HWP.RU.
Ngati simunatayebe m'mawu ndipo simukudziwa kuti "Edge" ndi chiyani, ndiye mwachidule, chisinthiko chinayamba motere:
- Poyamba, makampani akuluakulu adaganiza kuti Big Data iwathandiza kuti azigwira bwino ntchito, kuchokera ku miyala ya migodi mpaka kugulitsa chingamu pamisika yayikulu.
- Kenako adaganiza kuti ngati sensa iliyonse yopangidwa, kamera iliyonse ndi chosinthira chilichonse chilumikizidwa ndi netiweki wamba, telemetry yomwe ingakhalepo imatha kukhala gawo la Big Data ndikuthandizira kupewa kuba m'masitolo, kusweka kwa chobowola, kapena kuwongolera kutentha mung'anjo. . Chifukwa chake mabizinesi amakono apeza zida zambiri za IoT, masensa, zoyambitsa, mita, zosinthira ndi zina.
- Kupitilira apo paki ya IoT idafalikira "mpaka m'mphepete", idalowa m'matauni ang'onoang'ono, midzi, nkhalango ndi madambo, migodi ndi zitsime, zidawonekeratu kuti simungathe kulumikiza intaneti yothamanga kwambiri ku chinthu chilichonse, ndikutumiza zidziwitso zonse zenizeni. nthawi yayikulu Simudzakhala malo opangira data. Penapake kulibe intaneti konse, kupatulapo kulumikizana ndi mafoni a 3G/4G.
- Pakadali pano, zidawonekeratu kuti ma telemetry ambiri ochokera ku zida za IoT, komanso mawerengero ambiri, amatha kusinthidwa kwanuko pamalopo, ndipo mwina zomwe zakonzedwa kale komanso zokonzedwa kale kapena malipoti okhudza momwe amagwirira ntchito zitha kutumizidwa ku kampaniyo. main data center. Njira yosavuta yojambulira fanizo ili ndi makina owonera makanema: chifukwa chiyani muyenera kufalitsa mtsinje wonse kuchokera ku kamera kupita kumalo opangira data, pomwe mutha kutumiza zithunzi za zinthu zosuntha kapena malipoti okhala ndi zithunzi zopangidwa pogwiritsa ntchito ma templates ozindikira nkhope. . Njirayi imatithandiza kuti tisiye kwambiri machitidwe a nthawi yeniyeni ndikulola kusinthana kwa deta nthawi ndi nthawi, mwachitsanzo, kamodzi mphindi zingapo. Ili ndilo lingaliro la "edge computing", Edge yemweyo yemwe akuloseredwa kukhala ndi tsogolo labwino. M'chinenero chathu, ndizozoloΕ΅era kunena kuti "pansi", kapena "pamphepete", ndiko kuti, kutali ndi maofesi okongola a galasi, komanso pafupi ndi anthu.
Ndipo zinapezeka kuti ma seva wamba ndi osayenera kugwira ntchito "pambali": ndi okwera mtengo kwambiri, osakhwima, amatenthedwa mosavuta, amamveka phokoso, amatenga malo ambiri ndikubweretsa mavuto ambiri ogwirira ntchito. ndikosavuta kugwiritsa ntchito ma laputopu amphamvu pamakompyuta.

Mwachibadwa, makampaniwa adayankha zovuta za nthawi yathu poyambitsa gulu latsopano la zipangizo: seva ya msewu uliwonse, yaying'ono, yolimba, yowonongeka, yotetezeka ... mukumva ... palibe zomwe zili pamwambazi zomwe zimagwira ntchito zakale. maseva! Kukumana .
fomu Factor
Ma seva am'mphepete alibe mtundu umodzi wa chassis: mu shopu yamatabwa mumayipachika pakhoma, koma muhema wopumira mumangopachika patebulo, kotero Lenovo adapanga ThinkServer SE350 yake kukhala yaying'ono momwe mungathere. Ili ndi kutalika kwa 1U (40mm), kutalika kwa thupi ndi 0.5U (215mm), ndi kutalika kwa 376mm.
Mutha kunena kuti seva iyi ndi 1/2U kukula kwake ndipo imatha kunyamulidwa mozungulira ngati laputopu, koma sizili choncho. Tinayiwala za magetsi, omwe alipo awiri, ndipo onse ndi akunja, aakulu kwambiri, ndi mphamvu ya 240 W iliyonse. Ndi katundu wotere, makina onse a makina amatha kugawidwa mosavuta pawiri, chifukwa amafunika malo awiri pakhoma, mumayika seva patebulo - mphamvu zamagetsi pansi pa tebulo, ndi zina zotero. Zoonadi, ndizotheka kukhazikitsa makina awiri mu 1 unit kapena 2 mayunitsi a seva kabati, koma njira iyi imatengedwa ngati zosiyana, ndipo zithunzi zoyikapo ziyenera kugulidwa mosiyana.
Mwachikhazikitso, wopanga akuwonetsa kugwiritsa ntchito seva ndi zida zamagetsi kuti zikhazikike pakhoma, pomwe makinawo amakhala ndi mabatani amphamvu achitsulo. Poganizira kuti tsambalo silingakhale ndi chosinthira chosavuta chapaintaneti "pamphepete", ndipo Thinkserver SE350 palokha imasewera gawo lofikira pa Wi-Fi, kuyipachika pamwamba ndi lingaliro labwino. Chabwino, musaiwale kuti padzakhala magetsi awiri atapachikidwa pa bulaketi pafupi. Mwa njira, opanga awo ndi FSP, ndipo ndi ulemu wonse kwa kampaniyi, pazida za Enterprise, wopereka uyu siwosankha bwino; Ndikufuna kuwona magetsi a Delta kapena Seasonic.
Malinga ndi zotsatira zoyesa, magetsi a FSP amawonetsa bwino kwa adaputala akunja. Ndikupangira kulumikiza imodzi mwamagetsi kumalo osungiramo UPS osagwiritsidwa ntchito, kapena omwe amazimitsidwa ndi timer, kuti awonjezere moyo wa batri wa seva. 2KVA UPS wamba ipereka pafupifupi maola atatu a moyo wa batri wa seva. Choncho ngakhale jenereta itatha dizilo, mudzakhala ndi nthawi yopita kumalo opangira mafuta.
Chitetezo chakuba
Pofuna kupewa munthu wodutsa mwachisawawa kapena wantchito wanu kuti asachotse ndi kukokera seva kunyumba, bulaketi ili ndi loko ya Kensington yokhala ndi bawuti yamphamvu yoletsa kuba yomwe imatsekera makinawo mubulaketi. Mutha kuchotsa ThinkServer SE350 pakhoma popanda kiyi pogwiritsa ntchito khwangwala ndikung'amba bulaketi limodzi ndi ma dowels.
Koma ngati mukuwopa kuti woukira adzaba seva yanu ndikuyigulitsa pa Avito, ndiye musadandaule: Lenovo ThinkServer SE350 ilinso ndi chitetezo chakuba pakompyuta, monga mafoni amakono ndi laputopu. Mukagula, mumatsegula seva patsamba la Lenovo pogwiritsa ntchito nambala ya QR pamilandu yake, mtundu ndi nambala ya serial. Mwa kulumikiza makinawo ku akaunti yanu, mumangothandizira chitetezo mu BIOS ndikuyambitsa masensa omwe adamangidwa. Pali ziwiri zokha mwa izo: yoyamba ndi yodziwika bwino yotsegula chivundikiro, chomwe, mwa njira, sichingatsegulidwe popanda kuchotsa bulaketi, ndipo chachiwiri ndi sensa yomwe imalemba, mwachitsanzo, kuti galimotoyo ikulendewera mu yoyima, koma tsopano ili yopingasa.
Seva ikangozindikira kuti kuyesa kwachitika kuti kube, sikungotsekedwa, komanso "kuzimitsa" maukonde ake, kuphatikizapo Wi-Fi, LTE ndi mawaya, ndipo akhoza kubwezeretsedwa ntchito. kudzera munjira yokonzanso mu ntchito yamtambo ya Lenovo pogwiritsa ntchito kulumikiza foni yamakono kapena patali. Kuletsa dongosolo kuti lisapereke ma alarm abodza m'malo ogwedezeka, chidwi ndi malo amasinthidwa kuchokera ku BIOS. Chifukwa chake, kuba pofuna kugulitsanso sikumveka, ndipo owukirawo sadzachita chiwopsezo cha MITM poyika seva pamalo awo amtaneti. Mukamagwiritsa ntchito ma drive a SED, makiyi a encryption amathanso kuchotsedwa, koma popeza zida izi ndizoletsedwa kuitanitsa m'maiko ambiri, timadutsa ntchitoyi, ndikukumbutsa owerenga kuti matekinolojewa amangoteteza nsanja yokha, komanso kuti asagwiritse ntchito Bitlocker, Truecrypt kapena zina. zikutanthauza kubisa sikoyenera.
Inde, ndikadakhala wopanga, ndikadayika zomata zazikulu m'paketi ndi seva zomwe zili ndi mawu ngati "kompyuta yasungidwa" kapena "anti-kuba imayikidwa," chifukwa wowukirayo sadziwa kuti ndi wopanda pake. kuba ThinkServer SE350: simudzapeza chilichonse koma mavuto.
Chitetezo cha fumbi
Pali fumbi labwino ngakhale m'malo okwera mtengo kwambiri, ndipo popanga kapena m'munda pali zinthu zambiri izi, koma Lenovo ali ndi chitetezo ngati zosefera za thovu zomwe zimayikidwa pamafelemu pansi pa bezel yakutsogolo. Fyuluta yoyamba imakwirira mpweya waukulu womwe purosesa imawomberedwa, ndipo fyuluta yachiwiri imakwirira bolodi lokulitsa.
Kuphatikiza apo, doko lililonse ndi soketi iliyonse yakunja pa seva imakhala ndi pulagi yolimba ya rabara. Sindinawonepo chivundikiro pa Mini-USB kapena RJ45 kale, koma apa ngakhale soketi ya mlongoti ngakhale bowo la soketi ya mlongoti ali ndi kapu yawoyawo. Zonsezi, simuyenera kudandaula kuti seva idzameza mchenga kapena fumbi ndikuyamba kuzizira. Zikomo, Lenovo, mwachita bwino!
Kulankhulana opanda zingwe
Pali mitundu itatu ya Thinkserver SE350 yokhala ndi masinthidwe osiyanasiyana a doko la netiweki, akuwonetsedwa pazithunzi pansipa. Tili ndi imodzi yomaliza, yomwe ili ndi:
- 2 SFP + mipata ya 10 Gbps,
- 2 SFP mipata ya 1 Gbps,
- 1 RJ45 ya BMC
- 2 RJ45 pa 1 Gbit / s
Woyang'anira maukonde wamkulu pano ndi Intel x722, yomwe imapereka njira 4 za 10 Gbps, ziwiri zomwe zimayendetsedwa ku SFP + mipata, imodzi sikugwiritsidwa ntchito, ndipo yotsalayo imalumikizidwa ndi bolodi la Edgeboard, lomwe kwenikweni ndi rauta yopanda zingwe yomwe imagwira ntchito. pafupifupi mosadalira seva.
Mwakuthupi, Edgeboard ndi gawo lomwe limaphatikiza makhadi awiri a Mini-PCIe ndi switch ya NXP LS1046A. Kuti muyike Nano-SIM khadi, muyenera kuchotsa gawoli pa seva, ndikudula tinyanga zonse. Mumangokhala ndi kagawo ka SIM khadi imodzi, zomwe zimawoneka zachilendo m'dziko lamakono la mafoni apawiri-SIM ndi ma routers a WLAN. Module yopanda zingwe imathandizira muyezo wa 802.11ac wokhala ndi mitsinje iwiri yamalo, yomwe imapereka liwiro lalikulu la 433 Mbps.
Kusinthaku kumayendetsedwa mu hardware, kudzera mwa wolamulira wa BMC, XClarity Control. Apa mutha kusankha maudindo a doko 7, 5 ndi 6, komanso 8 ndi 9.
Izi ndizo, mwachidule, mumayendedwe ogwiritsira ntchito nthawi zonse mumakhala ndi ma doko a 10 Gigabit 1 ndi 2 omwe alipo ndipo Wi-Fi, LTE, madoko 5, 6 ndi 7 sapezeka. lembani 192.168.73.xx, kudzera momwe seva imalandira ndikugawa intaneti. Mwachitsanzo, pamwamba pakhoza kukhala 10G kuchokera kwa wothandizira + LTE, ndipo pansi kudzera pa gigabit RJ45 - malo onse ogwiritsira ntchito maukonde + Wi-Fi kuchokera kumalo ofikira seva. Ndizosangalatsa kuti ndi kasinthidwe uku, seva sichizindikira ngakhale kutha kwa netiweki pa imodzi mwa madoko. Ndipo inde, mutha kulumikiza foni yamakono yanu ngati modemu ya USB ngati palibe china chotsalira.
Chifukwa chiyani Lenovo adachita chinyengo chotere, ndipo sizingakhale zosavuta kukhazikitsa ma modemu osavuta ndi Wi-Fi yoyendetsedwa kuchokera ku OS? Mwina chinthu chachikulu ndi ntchito yodziyimira payokha ya gawo la Wi-Fi / LTE kuchokera pa seva: imatha kudzaza, kuzizira, kukhazikitsa zosintha, ndi zida zolumikizidwa ndi madoko a EdgeBoard ziyenera kulumikizidwa nthawi zonse pa intaneti. Kuphatikiza apo, muli ndi kudzipatula kwina kwa WAN kuchokera ku LAN pamlingo wa Hardware komanso malo olowera omwe ali ndi njira yosungira 4G. Koma, ndithudi, gawo lopanda zingwe liri ndi zoikamo zochepa, ndipo ntchito yake ikuwoneka yosamveka kwa wogwiritsa ntchito, kotero kuchokera ku lingaliro langa, kukhazikitsidwa koteroko kwa redundancy kumatsutsana kwambiri.
Makina osungira
Ndife okondwa kutsazikana ndi ma hard drive, kutumiza ngakhale mawonekedwe a 2.5-inch kuti aiwale. Lenovo ThinkServer SE350 imathandizira ma drive a M.2 okha, osati osinthika. Mwachidziwitso, makina osungira mu seva amagawidwa mumayendedwe a boot (M.2 khadi kumbuyo kwa riser, osaphatikizidwa mu kasinthidwe kwathu) ndi ma drive a data (NVME kapena SATA600). Mwachikhazikitso, kasinthidwe kwathu kumaphatikizapo mipata ya 4 M.2 NVME/SATA, yokhala ndi ma drive awiri a 480 GB SATA.
Mayesero akuwonetsa kuti awa ndi ma seva othamanga kwambiri omwe samachedwetsa liwiro panthawi yojambulira kwambiri, ndipo amakhala ndi nthawi yodziwikiratu yoyankha popanda zotsekereza.
Kuphatikiza apo, mutha kukhazikitsa chokwera chomwechi pamakhadi a 4 M.2 m'malo mwa khadi yokulitsa. Mukamagwiritsa ntchito ma drive a SED, mutha kugula ntchito yochotsa makiyi obisala pomwe masensa a tamper ndi anti-kuba ayambika. Ntchito za Hardware RAID zilipo pa adapter ya boot, yomwe imayika ma drive ofanana mugalasi, ndipo muyezo wa Intel software RAID ingagwiritsidwe ntchito posungira. Pazonse, mwana uyu akhoza kukhala ndi ma drive amtundu wa 10 M.2, omwe, mukuwona, ndi abwino kwambiri kwa theka lamilandu imodzi!
Zosankha zowonjezera
Palibe mnzanga yemwe adalingalira chifukwa chake panali wrench mkati mwa seva, koma zonse ndi zophweka: seva imapereka mwayi wotumiza antennas a Wi-Fi / LTE kuchokera kumbuyo kupita kutsogolo. Izi ndi zomwe fungulo liri. Mwachikhazikitso, seva imabwera ndi 1 16 GB DDR4 2666MHz ECC Registered module ndi chopanda chopanda kanthu cha khadi la PCI Express. Ma module a Memory omwe amatha mpaka 64 GB iliyonse yokhala ndi ma frequency a 2133/2400/2666 MHz okhala ndi mphamvu zonse mpaka 256 GB amathandizidwa.
Mukamayitanitsa, mutha kusankha kusinthidwa kwa purosesa kuchokera ku mndandanda wa Xeon-D 2100. Iyi ndi CPU yabwino kwambiri yomwe tayesa kale kale, imapangidwira makamaka machitidwe ophatikizidwa monga zipata zotetezera, NAS ndi ma node opangira makompyuta. Makina athu oyesera adayika Xeon-D 2123, 4-core yokhala ndi ma frequency frequency a 2.2 GHz, TurboBoost - 3.0 GHz, chithandizo cha HyperThreading, AVX-2 ndi AVX-512.
Seva BIOS imatha kuyika mtundu wogwiritsa ntchito mphamvu ya OS Control kuti igwirizane ndi malingaliro a VMware ogwiritsira ntchito Turbo Boost mkati mwa VM, komanso kuchepetsa kuchuluka kwa Turbo Boost pafupipafupi. M'mayesero athu, ma turbo frequency a purosesa sanapitirire 2.68 GHz, ndipo ngakhale ndidayesetsa bwanji, sindinathe kukweza ma frequency ake ngakhale mu 1-thread mode. Kuchokera pa zomwe ndakumana nazo nditha kunena kuti kwa Xeon-D kuchuluka kwa njira zokumbukira zomwe zikukhudzidwa sizofunikira monga kuchuluka kwa ma module omwe adayikidwa. Komanso, iyi ndi purosesa yotentha kwambiri ya purosesa yake ya 60 W, kotero musawopsyeze ngati ikuwotcha pamwamba pa madigiri a 60 ndi pafupifupi palibe katundu: dongosolo lozizira la seva liribe kanthu.
... makamaka popeza apa akuimiridwa ndi mafani atatu a 40 mm opangidwa ndi Delta Electronics okhala ndi anti-vibration mounts ndi kuthekera kosintha mosavuta (Cold Swap). Kuwongolera liwiro kumawalola kuti azigwira ntchito mosiyanasiyana kuyambira 3 RPM mpaka 000 RPM. Ikakhala yopanda ntchito kutentha kwachipinda, mulingo waphokoso umakhala pafupifupi 24 dB. Ndikufuna kuti ndizindikirenso kuti Lenovo ThinkServer SE000 ili ndi nthawi yayitali yogwira ntchito yotentha yozungulira: mpaka +38 digiri Celsius pamasinthidwe aliwonse ndikufika madigiri +350 mwa ena.
