Imodzi mwa ntchito zazikulu za bizinesi ndikukula ndi chitukuko. Zomwe zikuchitika masiku ano, kuchuluka kwa malo opangira zinthu, komanso kuwonekera kwa antchito atsopano ndi makontrakitala, kumatanthauza kuwonjezeka kosalekeza kwa katundu wamakampani a IT. Ichi ndichifukwa chake, pokhazikitsa yankho lililonse, woyang'anira IT wabizinesi ayenera kuganizira za chikhalidwe ngati scalability. Kutha kugwira ntchito yayikulu ndikuwonjezera katundu wambiri wowerengera ndikofunikira kwambiri kwa ma ISP. Tiyeni tiwone njira zokulirapo za Zimbra Collaboration Suite ngati chinthu chomwe chimagwiritsidwa ntchito ndi othandizira osiyanasiyana a SaaS padziko lonse lapansi.
Pali mitundu iwiri ya scalability: ofukula ndi yopingasa.

Zimbra Collabration Suite imathandizira makulitsidwe opingasa komanso ofukula.
Kukweza koyimirira ngati mwasankha kuwonjezera mphamvu zamakompyuta ku seva yanu sikudzakhala kosiyana kwambiri ndi kusamukira ku seva yatsopano, yamphamvu kwambiri ndi Zimbra. Komabe, ngati mutasankha kuwonjezera chosungira chachiwiri cha imelo ku seva, mudzakumana ndi malire omwe ali mu Zimbra Open-Source Edition. Chowonadi ndi chakuti mu mtundu waulere wa Zimbra simungathe kulumikiza ma voliyumu achiwiri kuti musunge imelo. Zowonjezera Zextras PowerStore zapangidwa kuti zithetse vutoli kwa ogwiritsa ntchito a Zimbra aulere, omwe amakulolani kulumikiza zonse zakuthupi ndi zamtambo S3 yosungirako yachiwiri ku seva. Kuphatikiza apo, PowerStore imaphatikizanso ma aligorivimu aku Zimbra omwe atha kupititsa patsogolo kusungirako deta pazama media omwe alipo.
Chofunikira makamaka ndikupanga ma voliyumu achiwiri pakati pa ma ISPs, omwe amapanga ma SSD othamanga koma okwera mtengo kwambiri, ndikuyika zosungirako zachiwiri pama HDD otsika koma otsika mtengo. Pogwiritsa ntchito maulalo owonekera, omwe amasungidwa pa SSD, dongosololi likupitilizabe kugwira ntchito mwachangu, ndipo kudzera kuphatikizika ndi kuchotsera, seva iliyonse imatha kusunga maimelo ambiri. Chotsatira chake, mtengo wamtengo wapatali wa ma seva omwe ali ndi yosungirako yachiwiri ndi Zextras PowerStore ndiwokwera kwambiri kuposa pamene mukugwiritsa ntchito machitidwe a Zimbra OSE.
Kukula kopingasa, mwa kutanthauzira, kungagwiritsidwe ntchito pazomangamanga zamaseva ambiri. Popeza pakuyika ma seva ambiri ma module onse a Zimbra amagawidwa pamakina osiyanasiyana, woyang'anira ali ndi mwayi wowonjezera ma seva a LDAP Replica, MTA ndi Proxy, komanso ma storages a makalata pafupifupi kosatha.
Njira yowonjezera ma node atsopano imabwereza ndondomeko yomwe yafotokozedwa za kuyika kwa Zimbra kwa ma seva ambiri. Ndikokwanira kungoyika ma module ofunikira a Zimbra pa seva ndikutchula adilesi ya Master LDAP, komanso kulowetsa deta kuti mutsimikizire. Pambuyo pake, ma node atsopano adzakhala gawo lachitukuko cha Zimbra, ndipo Zimbra Proxy idzapereka kusanja pakati pa ma seva. Panthawi imodzimodziyo, mabokosi onse omwe adapangidwa kale ndi zomwe zili mkati mwake zimakhalabe pazomwe zinalipo kale.
Nthawi zambiri, malo ogulitsira makalata atsopano amawonjezeredwa kuzipangizo za Zimbra, pamlingo wa seva imodzi pa 2500 ogwiritsa ntchito makasitomala atsamba la Zimbra komanso mpaka 5-6 ogwiritsa ntchito makompyuta ndi maimelo am'manja. Chiwerengero cha ogwiritsa ntchito chimakulolani kuti mukwaniritse zochitika zomvera kwambiri za seva ndikupewa mavuto ndi kupezeka komanso nthawi yayitali yolemetsa.
Kuphatikiza apo, oyang'anira ma seva ambiri amathanso kulumikiza masitolo achiwiri, komanso kuponderezana ndi kuchotsera pa sitolo iliyonse ya imelo pogwiritsa ntchito Zextras PowerStore. Kugwiritsa ntchito zimlet kumakupatsani mwayi wosunga mpaka 50% ya malo a disk, komanso, kuphatikiza ndi kuwonjezereka kwachuma kwazinthu zonse. Pankhani ya ma ISPs akulu, zotsatira zachuma pakukhathamiritsa kwazinthu zotere zitha kukhala zazikulu.
