Apple Mac ndi zida zapamwamba. LTO, SAS, Fiber Channel, eSATA

Mutu wankhaniyi ndikulumikiza zida zakunja ku Mac kudzera pa SAS, Fiber Channel (FC), eSATA. Tiyeni tinene mwamsanga kuti kuthetsa vuto la kupeza zipangizo zoterezi, pali njira kwa munthu wathanzi: kumanga PC yotsika mtengo, pulagi mu HBA SAS kapena FC controller khadi (mwachitsanzo, losavuta LSI adaputala), kulumikiza zipangizo zanu kuti. wowongolera uyu, ikani Linux iliyonse pa PC ndikugwira ntchito kuchokera ku Mac kudzera pa netiweki. Koma izi ndizoletsedwa komanso zosasangalatsa. Tidzapita njira yolimba ndikulumikiza zida zathu mwachindunji ku Mac.

Zomwe tikufuna izi:
- ndalama zabwino zogulira zida zatsopano, kapena mwayi wogulitsira pa eBay (komwe, ndi khama pang'ono, mutha kugula zida zofunika za mibadwo yam'mbuyo nthawi 10 zotsika mtengo kuposa mtengo wandandanda);
- Nkhani iyi.

Kuti mugwire ntchito ndi tepi ya maginito (yomwe tsopano ikuimiridwa padziko lonse mumtundu wa LTO), muyenera kukhala ndi LTO tepi drive (streamer) kapena laibulale ya tepi. Ichi ndi chipangizo chamtengo wapatali chogulira koyamba (kuchokera ku ma ruble mazana masauzande), koma mtengo wokwanira wandalama mukagula zogwiritsidwa ntchito. Popeza mibadwo ya LTO imasintha pafupifupi zaka ziwiri zilizonse, ndipo kuyanjana kumangokhala mibadwo iwiri, msika wachiwiri umakhala wodzaza ndi zida zogwirira ntchito zaka zinayi kapena kupitilira apo, i.e. m'badwo usanathe ndi kupitirira. Ngati mumagula chipangizo chatsopano pazinthu zamalonda, ndiye kuti mumamvetsetsa chifukwa chake mukuchifuna. Ngati mukufuna kugulira nyumba yanu ndi banja lanu, mutha kulingalira izi ngati njira yosungira zidziwitso (popeza ma media okha ndi otsika mtengo kwambiri pa 1 gigabyte).

Kuyambira mum'badwo wa LTO-5 (ndi gawo lina la LTO-4), zida zogwirira ntchito ndi tepi yamaginito zimalumikizidwa ndi kompyuta kudzera pa mawonekedwe a SAS kapena FC (nthawi zambiri pamakhala mitundu iwiri ya chipangizo chilichonse)

Kumbali ina, Apple imatipatsa mawonekedwe a USB-C mu Mac yathu (yogwiritsa ntchito ma protocol a USB, Thunderbolt 3 kapena DisplayPort), nthawi zina mawonekedwe a Ethernet, komanso Bingu 3 - Thunderbolt 2 ndi Bingu - FireWire 800. ma adapter.

Stalemate? Osati kwenikweni. Mwamwayi, Thunderbolt imatha kugwira ntchito mu PCIe ndikulola makhadi a PCIe kulumikizidwa chimodzimodzi ngati kuti adayikidwa mkati mwa kompyuta. Chifukwa cha izi, kukulitsa kulikonse kwa kasinthidwe ka Mac hardware ndikotheka, pokhapokha pali adapter yoyenera ndi madalaivala.

Mwachidziwitso, njira yosavuta yothetsera vutoli ndi bokosi lakunja la ma adapter a PCIe omwe ali ndi mawonekedwe a Thunderbolt (PCIe card expansion system), momwe mungathe kuyikapo adapter ya basi ya SAS kapena FC Host (HBA). Mwachitsanzo, mabokosi oterowo amapangidwa ndi kampani Sonnet ndi ena. Pali nuance apa: siwowongolera aliyense amene ali woyenera kwa ife, koma ndi amodzi okha omwe ali ndi dalaivala wa macOS. Pali matabwa ochepa okha, ndipo otsika mtengo komanso otchuka kwambiri (mwachitsanzo, LSI yomweyo) sakuphatikizidwa mu chiwerengero chawo. Mwamwayi, Sonnet adatenga vuto kuti apange tebulo zogwirizana Makhadi a PCIe okhala ndi OS osiyanasiyana kudzera pa mawonekedwe a Thunderbolt.

Njira ina ndiyo kugula Thunderbolt yokonzeka - SAS kapena Thunderbolt - FC interface converter, yomwe, kwenikweni, ndi msonkhano wokonzekera bokosi ndi wolamulira. Kampani yotchuka kwambiri m'derali ATTO, koma palinso zinthu zochokera kumakampani ena.

Dziwani kuti si onse olamulira a SAS ndi FC omwe ali ndi ziphaso kuti azitsatira mulingo wa LTO, popeza izi zokha zimawononga ndalama. Opanga ena amalemba mwachindunji kuti owongolera awo sanapangidwe kuti azigwira ntchito ndi ma tepi oyendetsa.

Kuti timalize chithunzichi, tikuwona kuti mLogic imapanga chida, yomwe ndi IBM LTO-8 pagalimoto muzochitika zakunja, momwe chosinthira cha SAS kupita ku Thunderbolt 3 chimaphatikizidwa nthawi yomweyo. Izi, komabe, ndi chinthu chodabwitsa kwambiri kuposa zonse zomwe zafotokozedwa pamwambapa, makamaka ndi miyezo ya dera lathu. Ndikukayika kuti chipangizochi chitha kutumizidwa ku Russia mwalamulo (ma drive a LTO ali ndi mawonekedwe a cryptographic, ndipo opanga monga IBM ndi HP amalandira chilolezo cha FSB kutengera mtundu uliwonse pazifukwa izi).

Kenaka, tikambirana, mwachitsanzo, zida zinazake, mwiniwake wa mwiniwakeyo yemwe adakhalapo chifukwa cha zogula zingapo zopambana, koma mfundo yaikulu iyenera kusungidwa pazosankha zonse.

Chifukwa chake tili ndi zida zotsatirazi zogwirira ntchito ndi tepi:
- Kompyuta ya Apple Mac mini 2018 yokhala ndi macOS 10.15 Catalina, yokhala ndi madoko a USB-C ndi chithandizo cha Thunderbolt 3;
- Adaputala ya Apple Thunderbolt 3 / Thunderbolt 2;
- Apple Thunderbolt 2 chingwe;
- ATTO ThunderLink SH 1068 chosinthira mawonekedwe (2 * Thunderbolt / 2 * SAS-2);
- SAS chingwe SFF-8088 - SFF-8088;
- tepi galimoto LTO-5 IBM TS2350;
- Makatiriji a LTO-5, kuyeretsa katiriji.

Tsopano, monga akunena, ndi zinthu zonsezi tiyesa kuchotsa.

Timatsitsa patsamba la ATTO mtundu waposachedwa kwambiri wa dalaivala wa ThunderLink SH 1068 (mwachiwonekere, kuti tithandizire, amaphatikizidwa ndi dalaivala wa SH 2068 ndipo ili mu gawo 2068, lomwe limalembedwa mkati mwazosungira ndi dalaivala) ndi Kusintha kwa ATTO.

Dalaivala, ndithudi, amafunika kuyika. Izi zisanachitike, wolemba amalangiza kuti nthawi zonse azitenga chithunzithunzi cha fayilo ya APFS ya boot disk ndi lamulo.

kapena kopi yosungira ya boot disk, ngati ili ndi HFS +. Simudziwa. Ndiye kudzakhala kosavuta kugubuduza mmbuyo kuchokera chithunzithunzi.

Chotsatira, osadziwa koma ochita khama mosakayikira adzakonda kuwerenga mosamala malangizo oyika oyendetsa a ATTO ndikuwatsata. Zotsatira zake - tadam! - timapeza makina ogwiritsira ntchito omwe amapachikidwa pa malo otsegula. Apa tingafunike chithunzithunzi chomwe titha kuchira poyimbira makina a Time kuchokera kugawo lobwezeretsa, kapena kuchokera kugawo lomwelo lothandizira titha kuchotsa pamanja kext yomwe ili ndi matenda ku bukhu lowonjezera la kernel (wolemba samalimbikitsa kuchita izi).

N’chifukwa chiyani zimenezi zikuchitika? Chifukwa Apple adatisamalira. M'mitundu yaposachedwa ya macOS, simungathe kubaya khodi yakunja mosavuta poyambira. Okonza mapulogalamu abwino a Apple aletsa khalidwe lowonongali. Zowonjezereka, adaziletsa theka, pamene kuyembekezera kwa dalaivala kukuchitika, koma dalaivala mwiniyo sali, choncho chirichonse chimangozizira.

Kodi maganizo okhwima ayenera kuchita chiyani asanayike dalaivala? Choyamba, perekani lamulo:

Ngati poyankha timalandira:

Kutetezedwa kwa System Integrity: kuyatsa.

ndiye izi zikutanthauza kuti opanga mapulogalamu abwino a Apple amasamala za ife, kotero palibe chomwe chingatiyendere mpaka titayimitsa chitetezo chawo chodabwitsa. Kuti muchite izi, yambitsaninso gawo lobwezeretsa (⌘R), imbani foni ndikutulutsa lamulo:

Pambuyo pake, timayambiranso kugwiritsira ntchito, ndikuyikanso dalaivala, ndipo panthawi imodzimodziyo yokonza makina a ATTO (makamaka, zida zosinthira zimafunikira kokha pazidziwitso ndipo sizikufunika pakugwira ntchito yachibadwa). Panjira, tikafunsidwa, timatsimikizira chilolezo cha ATTO muzokonda zamakina. Pambuyo kukhazikitsa, mukhoza kuyambiransoko mu gawo lobwezeretsa ndikupereka lamulo

Tsopano tili ndi mawonekedwe oyendetsedwa ndi dalaivala ku zida zakunja za SAS (kapena FC, ngati chosinthira cha FC chidagwiritsidwa ntchito). Koma momwe mungagwiritsire ntchito tepi pamlingo womveka?

Monga momwe malingaliro osadziwa koma odziwa zambiri akudziwa, dongosolo lililonse logwirizana ndi Unix limathandizira ma tepi oyendetsa pamlingo wa kernel ndi zofunikira za dongosolo, zomwe makamaka zimaphatikizapo mt (kasamalidwe ka tepi) ndi tar (archiver yomwe imathandizira kugwira ntchito ndi zolemba pa tepi) . Komabe, kodi maganizo apamwamba anganene chiyani pa izi? Dongosolo lililonse logwirizana ndi Unix, kupatula macOS. Apple idatisamalira pochotsa thandizo la zida za tepi pamakhodi ake.

Koma kodi ndizosatheka kubweza kachidindoyi poyika zida za Unix zotseguka ku macOS? Nkhani yabwino ndiyakuti Tolis (yomwe sindikulumikiza) wachita kale izi muzogulitsa zawo Tolis Tape Tools. Nkhani yoyipa ndi yakuti kampani yomwe yatchulidwayi imawononga $ 399 kuti igwiritse ntchito zotsatira za ntchito yake. Ziwerengero za izi zitha kusiyanasiyana, koma wolembayo sanakonzekere kulipira munthu ndalama 400 pa code yomwe idalembedwa kwambiri ndi anthu osiyanasiyana ndipo yakhala ikugwiritsidwa ntchito poyera kuyambira 1970s, chifukwa chake wolemba akudzifunsa yekha funsoli. amaganiza zatsekedwa. (Mwa njira, pali pulojekiti yaulere yosiyidwa m'malo osadziwika bwino pa Github IOSCSITApe pa mutu womwewo).

Mwamwayi, pali bungwe la IBM padziko lonse lapansi, zomwe zilakolako zawo zamalonda zili pamlingo wosiyana kwambiri, choncho sizidziwonetsera muzinthu zazing'ono zilizonse. Makamaka, idapanga mawonekedwe otseguka a tepi a LTFS, omwe amagawidwanso kwa macOS.

Chenjezo apa ndikuti opanga zida zamatepi osiyanasiyana amamasula mitundu yawo ya LTFS kuti athandizire zida zawo. Popeza wolemba amagwiritsa ntchito tepi ya IBM, adayika LTFS kuchokera ku IBM. Ma drive a chipani chachitatu angafunike madoko awo a LTFS. Ndipo pali kukhazikitsidwa kwapadziko lonse kwa openLTFS pa Github ndi Homebrew.

Ndikofunikira kwa ife kuti LTFS igwiritse ntchito ntchito yogawa media, motero imatha kugwira ntchito ndi zida ndi makatiriji kuyambira ku m'badwo wa LTO-5.

Chifukwa chake, kwa ife, timatsitsa IBM Spectrum Archive Single Drive Edition ya macOS kuchokera patsamba la IBM, lomwe limaphatikizapo kukhazikitsa kwa LTFS. Popanda zochitika zilizonse, timayika malondawo pogwiritsa ntchito choyikira chake. Panjira, amayikanso phukusi la FUSE, ndipo pamakonzedwe a dongosolo ayenera kutsimikizira kuvomereza kwa pulogalamu yanzeru yotchedwa Anatol Pomozov, yemwe pankhaniyi IBM yonse imadalira. Ulemu ndi ulemu kwa munthu uyu.

Ndikoyenera kulemba mzere mufayiloyo nthawi yomweyo /Library/Frameworks/LTFS.framework/Versions/Current/etc/ltfs.conf.local:

kusankha single-drive sync_type=nthawi @1

zomwe zimanena kuti tepiyo imayikidwa mwachisawawa ndipo chosungira chojambulira chimakonzedwanso pambuyo pa mphindi imodzi ya kusagwira ntchito (zosakhazikika ndi mphindi 1).

Pomaliza, zonse zakonzeka kulumikiza. Timalumikiza unyolo: Mac - T3 / T2 adaputala - Chingwe cha Thunderbolt - ATTO converter - SAS chingwe - tepi drive (kusankha madoko angapo pa Mac, chosinthira ndi kuyendetsa sikofunikira). Yatsani mphamvu ya chosinthira. Yatsani mphamvu ku tepi yoyendetsa. Timadikirira kuti kuyendetsa kumalize kuyambika molingana ndi zomwe zikuwonetsa.

Timapereka lamulo:
