Rimwe rematambudziko makuru ebhizinesi kukura nekusimudzira. Muchokwadi chemazuva ano, kuwedzera kwenhamba yezvivakwa zvekugadzira, pamwe nekubuda kwevashandi vatsva uye makondirakiti, zvinoreva kuwedzera nguva dzose mutoro weiyo bhizinesi IT zvivakwa. Ndokusaka, pakuita chero mhinduro, bhizinesi IT maneja inofanirwa kufunga nezve hunhu hwakadai se scalability. Iko kugona kubata mikuru yebasa uchiwedzera mitoro yakakura yemakomputa inonyanya kukosha kune ISPs. Ngatitarisei kuti Zimbra Collaboration Suite inopa sei scalability sechigadzirwa chinoshandiswa nevakasiyana SaaS vanopa pasirese.
Kune marudzi maviri e scalability: vertical uye horizontal. Muchiitiko chekutanga, kuwedzera kwekugadzirisa kwekugadzirisa kunowanikwa nekuwedzera komputa uye mamwe masimba kune aripo IT infrastructure node, uye mune yechipiri, kuwedzera kwekuita kunowanikwa nekuwedzera itsva computing nodes, iyo inotora chikamu chemutoro. Zimbra Collabration Suite inotsigira zvese zvakachinjika uye zvakamira kuyera.
Vertical scaling kana ukafunga kuwedzera computing power kune server yako inenge isina kunyanya kusiyana nekutamira kune itsva, ine simba server neZimbra. Nekudaro, kana iwe ukafunga kuwedzera yechipiri email kuchengetedza kune yako sevha, iwe zvechokwadi uchasangana nekupikiswa kunowanikwa muZimbra Open-Source Edition. Icho chokwadi ndechekuti mune yemahara vhezheni yeZimbra haugone kubatanidza mavhoriyamu echipiri ekuchengetedza email. Iyo Zextras PowerStore yekuwedzera yakagadzirirwa kugadzirisa nyaya iyi kune vashandisi veiyo yemahara edition yeZimbra, iyo inokutendera kuti ubatanidze zvese zvemuviri uye negore S3 yechipiri chengetedzo kune server. Pamusoro pezvo, PowerStore inosanganisira kudzvanya uye deduplication algorithms muZimbra iyo inogona kuvandudza kugona kwekuchengetedza data pane iripo midhiya.
Kugadzirwa kwemavhoriyamu echipiri kunonyanya kudiwa pakati peISPs, iyo inoshandisa nekukurumidza asi inodhura maSSD seyekutanga kuchengetedza, uye nekuisa echipiri pane anononoka asi anochipa HDD. Nekushandisa pachena zvinongedzo izvo zvakachengetwa paSSD, sisitimu inoramba ichishanda nekukasira, uye kuburikidza nekudzvanyirira uye kudzoreredza, sevha yega yega inogona kuchengeta mamwe maemail akawanda. Nekuda kweizvozvo, mutengo unoshanda wemaseva ane yechipiri chengetedzo uye Zextras PowerStore yakanyanya kukwirira pane kushandisa yakajairwa Zimbra OSE mashandiro.
Horizontal scaling, netsanangudzo, inogona chete kushandiswa mune yakawanda-server masisitimu. Sezvo panguva yekumisikidzwa kwema-multi-server, ese maZimbra modules akagoverwa pamichina yakasiyana, maneja ane mukana wekuwedzera mamwe uye akawanda LDAP Replica, MTA uye Proxy maseva, pamwe chete neemail storages, zvisingaite.
Maitiro ekuwedzera node matsva anodzokorora maitiro anotsanangurwa nezve multi-server kuisirwa Zimbra. Iwe unongoda kuisa iyo inodiwa Zimbra modules pane sevha uye tsanangura iyo Master LDAP kero, pamwe nekuisa iyo yechokwadi data. Mushure meizvi, node nyowani dzichava chikamu cheZimbra zvivakwa, uye Zimbra Proxy ichapa kuyera kuyera pakati pemaseva. Muchiitiko ichi, ese akagadzirwa kare mabhokisi etsamba uye zvirimo zvinoramba zviri munzvimbo dzekuchengetera kwazvaive kare.
Kazhinji, matura matsva etsamba anowedzerwa kuZimbra zvivakwa, pamwero wesevha imwe pa2500 vashandisi vanoshanda veZimbra web client uye vanosvika zviuru zvishanu nemazana matanhatu evashandisi vedesktop uye mobile email vatengi. Iyi nhamba yevashandisi inokutendera iwe kuti uwane yakanyanya kupindurwa server kuita uye kudzivirira matambudziko nekuwanikwa uye kureba kurodha nguva.
Uye zvakare, vatariri veakawanda-server zvivakwa vanogona zvakare kubatanidza sekondari zvichengetedzo, pamwe nekumanikidza uye kudonhedza pane yega email yekuchengetedza uchishandisa Zextras PowerStore. Kushandisa iyi winterlet inokubvumira kuchengetedza kusvika ku50% yedhisiki nzvimbo, uye pamwe chete nekuwedzera kubudirira kwehupfumi hwehupfumi hwose. Panyaya yeISPs hombe, hupfumi hwekugadzirisa kwezvivakwa zvakadaro hunogona kusvika kuhukuru hukuru.
