Kuitwa kwechero IT mhinduro mune bhizinesi kunotanga nekugadzira. Panguva ino, maneja weIT anozofanira kuverenga huwandu hwemasevha uye hunhu hwawo kuitira kuti, kune rumwe rutivi, kune akakwana kune vese vashandisi, uye kune imwe, kuitira kuti mutengo-mhando reshiyo yemaseva aya. yakanyatsonaka uye mari yekugadzira komputa yeruzivo rwehurongwa hutsva haina kuitwa gomba rakakura mubhajeti reIT rebhizinesi. Ngationei kuti tingagadzira sei zvivakwa zvekuitwa kwebhizinesi reZimbra Collaboration Suite.
Chinhu chikuru cheZimbra mukuenzanisa nemamwe magadzirirwo ndechekuti mune yeZCS, iyo bhodhoro haawanzo processor simba kana RAM. Mhedzisiro huru inowanzo mhanyisa yekupinza uye kubuda kweiyo hard drive uye saka kutarisisa kukuru kunofanirwa kubhadharwa kune kuchengetedza data. Zvinotaurwa zviri pamutemo zvinodikanwa zvishoma zveZimbra munzvimbo yekugadzira 4-core 64-bit processor ine 2 gigahertz wachi kumhanya, 10 gigabytes yemafaira ehurongwa uye matanda, uye angangoita masere gigabytes eRAM. Kazhinji, maitiro aya akakwana kuti sevha ishande zvine musoro. Asi ko kana uchifanira kushandisa Zimbra yevashandisi zviuru gumi? Ndeapi maseva uye anofanirwa kuitwa sei mune iyi kesi?
Ngatitangei nenyaya yekuti zvivakwa zvevashandisi zviuru gumi zvinofanirwa kunge zviri ma-multi-server. Iyo yakawanda-server dhizaini, kune rumwe rutivi, inobvumira Zimbra kuti ive scalable, uye kune imwe, kuti iwane inoteedzera mashandiro ehurongwa hweruzivo kunyangwe nekuwanda kwevashandisi. Zvinowanzo kuoma kufanotaura kuti vangani vashandisi veZimbra server vachakwanisa kushanda nemazvo, nekuti zvakawanda zvinoenderana nekusimba kwebasa ravo nemakarenda neemail, pamwe neprotocol inoshandiswa. Ndokusaka, semuenzaniso, isu tichashandisa 10 mail storages. Kana paine kushomeka kana kunyanyisa kuwanda kwesimba, zvinokwanisika kudzima kana kuwedzera imwe.
Saka, kana uchigadzira zvivakwa zvevanhu zviuru gumi, iwe uchafanirwa kugadzira LDAP, MTA uye Proxy maseva uye 10.000 mail storages. Ziva kuti LDAP, MTA neProxy maseva anogona kuitwa chaiwo. Izvi zvinoderedza mutengo we server Hardware uye kuita kuti zvive nyore kuchengetedza uye kudzoreredza data, asi kune rumwe rutivi, kana sevha yemuviri ikatadza, iwe uri panjodzi yekuve nekukurumidza pasina MTA, LDAP uye Proxy. Ndokusaka sarudzo pakati pemasevha emuviri kana chaiwo anofanirwa kuitwa zvichienderana nekuti inguva yakawanda sei yaunogona kutenga kana paine emergency. Kuchengetera tsamba kwaizoiswa zvakanyanya pamasevha emuviri, nekuti pavari ndipo pazvizhinji zvekunyora kutenderera kuchaitika, izvo zvinodzikamisa kushanda kweZimbra, uye nekudaro nhamba yakakura yematanho ekufambisa data ichawedzera zvakanyanya kuita kweZimbra.
Muchidimbu, mushure mekugadzira LDAP, MTA, maProxy maseva, kuchengetedza netiweki uye nekuasanganisa kuita chivakwa chimwe chete, Zimbra Collaboration Suite yevashandisi zviuru gumi yakagadzirira kutumirwa. Kushanda kwegadziriro iyi kunenge kuri nyore:
Iyo dhizaini inoratidza mahombe node ehurongwa uye data inoyerera iyo inotenderera pakati pavo. Nechigadziro ichi, zvigadziriso zvichange zvisina kudzivirirwa zvachose kubva pakurasikirwa kwedata, kuderera kunobatanidza nekukundikana kweimwe sevhavha, nezvimwe zvakadaro. Ngatitarisei chaizvo kuti ungadzivirira sei zvivakwa zvako kubva kumatambudziko aya.
Nzira huru ndeye hardware redundancy. Yekuwedzera MTA uye Proxy node inogona, kana paine kutadza kwemasevha makuru, kwenguva pfupi kutora basa reakanyanya. Kudzokorodza node dzezvivakwa zvakakosha ipfungwa yakanaka nguva dzose, asi haisi nguva dzose inogoneka kusvika painodiwa. Muenzaniso unoshamisa ndewekuchengetwa kwemaseva panochengetwa tsamba. Parizvino, Zimbra Collaboration Suite Open-Source Edition haitsigire kugadzirwa kwezvitoro zvakapetwa, saka kana imwe yemaseva aya ikatadza, nguva yekudzikira haizodzivirirwe, uye kuderedza kuderera kunokonzerwa nekutadza kwechitoro chetsamba, maneja weIT anogona kuendesa backup yayo. kopi pane imwe server.
Sezvo pasina yakavakirwa-mukati backup system muZimbra OSE, isu tichada Zextras Backup, iyo inotsigira chaiyo-nguva backup, uye kunze kwekuchengetedza. Sezvo Zextras Backup, pakuita zvizere uye kuwedzera backups, inoisa data rese mu / opt/zimbra/backup folda, zvingave zvine musoro kukwira kunze, network kana kunyange chengetedzo yegore mairi, kuitira kuti kana imwe yemaseva ikatadza, iwe uchave nevezvenhau nekopi yekuchengetedza yaive iripo panguva yenjodzi. Inogona kuiswa pane backup yemuviri server, pamushini chaiwo, kana mugore. Iyo zvakare pfungwa yakanaka yekuisa MTA ine spam sefa pamberi peZimbra Proxy server kuderedza huwandu hwejunk traffic inouya kune server.
Nekuda kweizvozvo, iyo yakachengetedzwa Zimbra zvivakwa zvinotaridzika seizvi:
Nekugadzirisa uku, zvivakwa zveZimbra hazvizongokwanisa kupa mabasa epamusoro kune vashandisi ve10.000, asiwo kana pane chiitiko chekukurumidzira, chichabvumira kuti migumisiro yaro ibviswe nokukurumidza sezvinobvira.
