Omunye wemisebenzi esemqoka yebhizinisi ukukhula nokuthuthuka. Ezimweni zanamuhla, ukwanda kwenani lezikhungo zokukhiqiza, kanye nokuvela kwabasebenzi abasha kanye nosonkontileka, kusho ukwanda okuqhubekayo komthwalo engqalasizinda ye-IT yebhizinisi. Kungakho, lapho esebenzisa noma yisiphi isixazululo, umphathi we-IT webhizinisi kufanele acabangele isici esinjengokwenyuka. Ikhono lokusingatha umsebenzi omkhulu ngenkathi wengeza imithwalo emikhulu yekhompyutha ibaluleke kakhulu kuma-ISP. Ake sibheke izinketho zokukala ezinikezwa yi-Zimbra Collaboration Suite njengomkhiqizo osetshenziswa abahlinzeki abahlukahlukene be-SaaS emhlabeni jikelele.
Kunezinhlobo ezimbili ze-scalability: mpo kanye ne-horizontal. Esimweni sokuqala, ukuzuza kokusebenza kwesixazululo kufinyelelwa ngokungeza i-computing namanye amakhono kuma-node wengqalasizinda ye-IT ekhona, futhi esimweni sesibili, ukuzuza kokusebenza kufinyelelwa ngokungeza ama-node amasha ekhompyutha, athatha ingxenye yomthwalo. I-Zimbra Collabration Suite isekela kokubili ukukalwa okuvundlile nokuma mpo.
Ukulinganisa okuqondile uma kwenzeka unquma ukwengeza amandla ekhompyutha kuseva yakho ngeke kuhluke kakhulu ekuthutheleleni kuseva entsha, enamandla kakhulu nge-Zimbra. Nokho, uma uthatha isinqumo sokwengeza isitoreji sesibili se-imeyili kuseva, nakanjani uzongena emkhawulweni otholakala ku-Zimbra Open-Source Edition. Iqiniso liwukuthi enguqulweni yamahhala yeZimbra awukwazi ukuxhuma amavolumu esibili ukuze ugcine i-imeyili. Ukuze uxazulule le nkinga kubasebenzisi bohlelo lwamahhala lwe-Zimbra, isandiso se-Zextras PowerStore siklanyelwe, esikuvumela ukuthi uxhume kokubili isitoreji somzimba nesamafu sesibili se-S3 kuseva. Ukwengeza, i-PowerStore ihlanganisa ukucindezelwa nokuphindaphinda ama-algorithms e-Zimbra angathuthukisa ukusebenza kahle kokugcina idatha kumidiya ekhona.
Okudingeka kakhulu ukwakhiwa kwamavolumu esibili phakathi kwama-ISP, okwenza isitoreji esiyinhloko sama-SSD ashesha kodwa abize, futhi abeke isitoreji sesibili kuma-HDD ahamba kancane kodwa ashibhile. Ngokusetshenziswa kwezixhumanisi ezisobala, ezigcinwe ku-SSD, uhlelo luyaqhubeka nokusebenza ngokushesha, futhi ngokucindezelwa nokuphindaphinda, iseva ngayinye ingagcina ama-imeyili amaningi kakhulu. Ngenxa yalokho, ukuphumelela kwezindleko zamaseva anesitoreji sesibili kanye ne-Zextras PowerStore kuphezulu kakhulu kunalapho kusetshenziswa ukusebenza okujwayelekile kwe-Zimbra OSE.
Ukukala okuvundlile, ngokwencazelo, kungasetshenziswa kuphela kungqalasizinda yamaseva amaningi. Njengoba ekufakweni kwamaseva amaningi wonke amamojula e-Zimbra asatshalaliswa emishinini eyahlukene, umlawuli unethuba lokwengeza i-LDAP Replica, i-MTA kanye namaseva e-Proxy, kanye nokugcinwa kwemeyili cishe unomphela.
Inqubo yokwengeza amanodi amasha iphinda inqubo echaziwe mayelana nokufakwa kwe-Zimbra enamaseva amaningi. Kwanele ukufaka amamojula adingekayo e-Zimbra kuseva futhi ucacise ikheli le-LDAP le-Master, kanye nokufaka idatha yokuqinisekisa. Ngemva kwalokho, amanodi amasha azoba yingxenye yengqalasizinda ye-Zimbra, futhi i-Zimbra Proxy izohlinzeka ngokulinganisa komthwalo phakathi kwamaseva. Ngesikhathi esifanayo, wonke amabhokisi eposi adalwe ngaphambilini kanye nokuqukethwe kwawo kuhlala kusitoreji lapho ayekhona ngaphambili.
Ngokuvamile, izitolo zemeyili ezintsha zengezwa kungqalasizinda ye-Zimbra, ngenani leseva eyodwa ngabasebenzisi abangu-2500 abasebenzayo beklayenti lewebhu le-Zimbra kanye nabasebenzisi abafinyelela ezinkulungwaneni ezi-5-6 bedeskithophu kanye namaklayenti e-imeyili eselula. Le nombolo yabasebenzisi ikuvumela ukuthi ufinyelele isipiliyoni seseva esisabela kakhulu futhi ugweme izinkinga ngokutholakala nezikhathi zokulayisha ezinde.
Ukwengeza, abaphathi bengqalasizinda yamaseva amaningi bangakwazi futhi ukuxhuma izitolo zesibili, kanye nokucindezelwa kanye nokuphindaphinda esitolo ngasinye se-imeyili kusetshenziswa i-Zextras PowerStore. Ukusebenzisa le zimlet kukuvumela ukuthi wonge kuze kufike ku-50% wesikhala sediski, futhi, kuhambisana nokwanda kokusebenza kahle kwezomnotho kwengqalasizinda yonke. Endabeni yama-ISP amakhulu, umthelela wezomnotho wokuthuthukiswa okunjalo kwengqalasizinda ungaba mkhulu ngempela.
