Ukuphunyezwa kwaso nasiphi na isisombululo se-IT kwishishini kuqala ngoyilo. Kweli nqanaba, umphathi we-IT kuya kufuneka abale inani leeseva kunye neempawu zabo ukuze, kwelinye icala, banele kubo bonke abasebenzisi, kwaye kwelinye, ukwenzela ukuba umlinganiselo wexabiso lomgangatho wezi seva. ilungile kwaye iindleko zokudala iziseko zekhompuyutha zenkqubo entsha yolwazi awenziwanga mngxuma onzima kuhlahlo lwabiwo-mali lwe-IT yeshishini. Makhe sijonge ukuba siyilwa njani na isiseko sokuphunyezwa kweshishini leZimbra Collaboration Suite.
Into ephambili yeZimbra xa kuthelekiswa nezinye izisombululo kukuba kwimeko ye-ZCS, i-bottleneck ayinqabile amandla eprosesa okanye i-RAM. Umda oyintloko ngokuqhelekileyo ukukhawuleza kwegalelo kunye nemveliso ye-hard drive kwaye ngoko ke ingqwalasela ephambili kufuneka ihlawulwe kwisitoreji sedatha. Iimfuno ezincinci ezichazwe ngokusemthethweni ze-Zimbra kwindawo yokuvelisa ziyi-4-core 64-bit processor ene-2 ββgigahertz clock speed, i-10 gigabytes yeefayile zenkqubo kunye neelog, kunye ubuncinane ne-8 gigabytes ye-RAM. Ngokuqhelekileyo, ezi mpawu zanele ukuba umncedisi asebenze ngokuphendula. Kodwa kuthekani ukuba kufuneka usebenzise iZimbra kubasebenzisi abangamawaka ali-10? Zeziphi iiseva kwaye kufuneka ziphunyezwe njani kule meko?
Masiqale ngento yokuba isiseko sabasebenzisi abangamawaka ali-10 kufuneka sibe ngamaseva amaninzi. I-multi-server i-infrastructure, kwelinye icala, ivumela i-Zimbra ukuba ihlaziywe, kwaye kwelinye, ukufezekisa ukusebenza okuphendulayo kwenkqubo yolwazi kunye nokungena okukhulu kwabasebenzisi. Kuhlala kunzima ukuqikelela ngqo ukuba bangaphi abasebenzisi iseva yeZimbra abaya kukwazi ukubasebenzela ngokufanelekileyo, kuba okuninzi kuxhomekeke kubunzulu bomsebenzi wabo ngeekhalenda kunye ne-imeyile, kunye neprotocol esetyenziswayo. Kungenxa yoko, njengomzekelo, siya kuphumeza ii-storage ze-imeyile ezi-4. Kwimeko yokunqongophala okanye ukugqithisa okukhulu komthamo, kuya kwenzeka ukuba ucime okanye wongeze enye.
Ngaloo ndlela, xa uyila isiseko se-10.000 yabantu, kuya kufuneka udale i-LDAP, i-MTA kunye neeseva ze-Proxy kunye ne-4 yokugcina i-imeyile. Qaphela ukuba i-LDAP, i-MTA kunye neeseva ze-Proxy zingenziwa njengenyani. Oku kuya kunciphisa iindleko ze-hardware yomncedisi kwaye zenze kube lula ukugcinwa kunye nokubuyisela idatha, kodwa ngakolunye uhlangothi, ukuba umncedisi wenyama uyahluleka, ubeka ingozi ngokukhawuleza ngaphandle kwe-MTA, i-LDAP kunye ne-Proxy. Yiyo loo nto ukhetho phakathi kweeseva zomzimba okanye ezibambekayo kufuneka zenziwe ngokusekwe kubungakanani bexesha lokuphumla onokulifumana kwimeko kaxakeka. Ukugcinwa kwemeyile kuya kubekwa ngcono kwiiseva zomzimba, kuba kukho kubo ukuba uninzi lwemijikelezo yokubhala iya kwenzeka, enciphisa ukusebenza kweZimbra, kwaye ke inani elikhulu leendlela zokudluliselwa kwedatha liya kwandisa kakhulu ukusebenza kweZimbra.
Ngokomgaqo, emva kokudala i-LDAP, i-MTA, iiseva ze-Proxy, ukugcinwa kwenethiwekhi kunye nokudibanisa kwisiseko esisodwa, i-Zimbra Collaboration Suite yabasebenzisi be-10000 ilungele ukugunyaziswa. Ukusebenza kolu lungelelwaniso kuya kuba lula kakhulu:
Umzobo ubonisa iindawo eziphambili zenkqubo kunye nokuhamba kwedatha eya kujikeleza phakathi kwabo. Ngolu lungelelwaniso, iziseko zophuhliso aziyi kukhuselwa ngokupheleleyo ekulahlekeni kwedatha, ixesha lokuphumla elihambelana nokungaphumeleli kwayo nayiphi na iseva, njalo njalo. Makhe sijonge ngqo ukuba ungakhusela njani isiseko sakho kwezi ngxaki.
Eyona ndlela iphambili yi-hardware redundancy. I-MTA eyongezelelweyo kunye ne-Proxy nodes, xa kwenzeka ukungaphumeleli kweeseva eziphambili, okwethutyana kuthatha indima yezona ziphambili. Ukuphinda-phinda iindawo zeziseko ezingundoqo kusoloko kululuvo oluhle, kodwa akusoloko kusenzeka ngokomlinganiselo ofunekayo. Umzekelo omangalisayo kugcino lweeseva apho imeyile igcinwa khona. Okwangoku, iZimbra Collaboration Suite Open-Source Edition ayikuxhasi ukudalwa kweevenkile eziphindwe kabini, ke ukuba enye yezi seva iyasilela, ixesha lokuphumla alinakuthintelwa, kwaye ukunciphisa ixesha lokuphumla elibangelwa kukungaphumeleli kwevenkile yeposi, umphathi we-IT unokuhambisa ikopi yakhe yogcino. kwenye iseva.
Ekubeni akukho nkqubo yokugcina eyakhelwe-ngaphakathi kwi-Zimbra OSE, siya kufuna i-Zextras Backup, exhasa ukugcinwa kwexesha langempela, kunye nokugcinwa kwangaphandle. Ekubeni i-Zextras Backup, xa usenza i-backups epheleleyo kunye neyongezelelweyo, ibeka yonke idatha kwi-opt / zimbra / ifolda yokugcina, kuya kuba nengqiqo ukunyuka kwangaphandle, inethiwekhi okanye ukugcinwa kwefu kuyo, ukuze ukuba enye yeeseva iyasilela, uya kuba nemithombo yeendaba enekopi yokugcina eyayikho ngexesha likaxakeka. Ingafakwa kwi-backup server yomzimba, kumatshini obonakalayo, okanye kwilifu. Kwakhona ingcamango efanelekileyo yokufaka i-MTA kunye nesihluzo se-spam phambi komncedisi we-Zimbra Proxy ukunciphisa inani le-junk traffic ezayo kumncedisi.
Ngenxa yoko, iziseko ezikhuselekileyo zeZimbra ziya kujongeka ngolu hlobo:
Ngolu lungelelwaniso, iziseko zeZimbra aziyi kukwazi kuphela ukubonelela ngeenkonzo eziphezulu kubasebenzisi be-10.000, kodwa nakwimeko yemeko engxamisekileyo, iya kuvumela ukuba iziphumo zayo zipheliswe ngokukhawuleza.
