S\u0103 analiz\u0103m cum ar trebui s\u0103 fie proiectat\u0103 infrastructura pentru implementarea suitei Zimbra Collaboration \u00een cadrul companiei.<\/p>\n

\"Planificarea<\/a><\/noindex><\/p>\n

Principala caracteristic\u0103 a Zimbra \u00een compara\u021bie cu alte solu\u021bii este c\u0103, \u00een cazul ZCS, \u00abg\u00e2tul de sticl\u0103\u00bb rareori devine puterea procesorului sau memoria RAM. Principala limitare devine de obicei viteza de citire \u0219i scriere a discului dur, astfel c\u0103 aten\u021bia principal\u0103 ar trebui s\u0103 fie acordat\u0103 \u00een special stoc\u0103rii datelor. Cerin\u021bele minime oficial declarate pentru Zimbra \u00een medii de produc\u021bie sunt un procesor pe 64 de bi\u021bi cu 4 nuclee \u0219i 2 GHz, 10 GB pentru fi\u0219ierele de sistem \u0219i jurnale, precum \u0219i minimum 8 GB RAM. De obicei, aceste specifica\u021bii sunt suficiente pentru un server receptiv. Dar ce trebuie s\u0103 face\u021bi dac\u0103 dori\u021bi s\u0103 implementa\u021bi Zimbra pentru 10.000 de utilizatori? Ce servere \u0219i cum ar trebui implementate \u00een acest caz?<\/p>\n

S\u0103 \u00eencepem cu faptul c\u0103 infrastructura pentru 10.000 de utilizatori trebuie s\u0103 fie multi-server. Infrastructura multi-server permite, pe de o parte, scalarea Zimbra, iar pe de alt\u0103 parte, asigurarea func\u021bion\u0103rii receptive a sistemului informa\u021bional chiar \u0219i \u00een cazul unui aflux mare de utilizatori. De obicei, este destul de dificil s\u0103 prezice\u021bi c\u00e2\u021bi utilizatori poate sus\u021bine un server Zimbra \u00een mod calitativ, deoarece depinde foarte mult de intensitatea activit\u0103\u021bii lor cu calendarele \u0219i emailul, precum \u0219i de protocolul folosit. De aceea, pentru exemplu, vom implementa 4 stoc\u0103ri de email. \u00cen caz de deficit sau exces semnificativ de capacitate, se poate fie dezactiva, fie ad\u0103uga un altul.<\/p>\n

Astfel, \u00een proiectarea unei infrastructuri pentru 10.000 de oameni, va fi necesar s\u0103 crea\u021bi servere LDAP, MTA \u0219i Proxy, precum \u0219i 4 stoc\u0103ri de email. Este important de men\u021bionat c\u0103 serverele LDAP, MTA \u0219i Proxy pot fi virtualizate. Acest lucru va reduce costurile cu echipamentele serverului \u0219i va facilita backup-ul \u0219i recuperarea datelor, \u00eens\u0103, pe de alt\u0103 parte, \u00een cazul \u00een care serverul fizic se defecteaz\u0103, risca\u021bi s\u0103 r\u0103m\u00e2ne\u021bi repede f\u0103r\u0103 MTA, LDAP \u0219i Proxy. De aceea, alegerea \u00eentre servere fizice sau virtuale ar trebui s\u0103 se fac\u0103 \u00een func\u021bie de timpul de nefunc\u021bionare pe care v\u0103 permite\u021bi \u00een caz de urgen\u021b\u0103. Stoc\u0103rile de email ar trebui, de asemenea, s\u0103 fie plasate pe servere fizice, deoarece num\u0103rul principal de cicluri de scriere, care limiteaz\u0103 performan\u021ba Zimbra, va avea loc pe acestea, iar o l\u0103\u021bime de band\u0103 mai mare va permite o cre\u0219tere semnificativ\u0103 a performan\u021bei Zimbra. <\/p>\n

\u00cen principiu, dup\u0103 crearea servere<\/a> LDAP, MTA, Proxy, stoc\u0103ri de re\u021bea \u0219i integrarea acestora \u00eentr-o singur\u0103 infrastructur\u0103, Zimbra Collaboration Suite pentru 10.000 de utilizatori este preg\u0103tit\u0103 pentru implementare. Schema de func\u021bionare a acestei configura\u021bii va fi destul de simpl\u0103: <\/p>\n

\"Planificarea
\n
\nSchema ilustreaz\u0103 nodurile principale ale sistemului \u0219i fluxurile de date care vor circula \u00eentre acestea. Cu o astfel de configura\u021bie, infrastructura nu va fi deloc protejat\u0103 \u00eempotriva pierderii datelor, nefunc\u021bion\u0103rii cauzate de defectarea oric\u0103rui server \u0219i a\u0219a mai departe. S\u0103 vedem cum putem proteja infrastructura de aceste probleme.<\/p>\n

Metoda principal\u0103 este redundan\u021ba hardware. Nodurile suplimentare MTA \u0219i Proxy pot, \u00een caz de defectare a serverelor principale, prelua temporar rolul acestora. Duplicarea nodurilor unei infrastructuri critice este aproape \u00eentotdeauna o idee bun\u0103, dar nu \u00eentotdeauna poate fi implementat\u0103 \u00een volumul dorit. Un exemplu clar este rezervarea serverelor pe care este stocat\u0103 po\u0219ta. \u00cen prezent, Zimbra Collaboration Suite Open-Source Edition nu suport\u0103 crearea de stoc\u0103ri redundante, a\u0219a c\u0103, \u00een caz de defectare a uneia dintre aceste servere, nu se poate evita nefunc\u021bionarea, iar pentru a reduce timpul de nefunc\u021bionare provocat de defectarea stoc\u0103rii de email, IT managerul poate desf\u0103\u0219ura backup-ul acesteia pe un alt server. server<\/a>. <\/p>\n

Deoarece Zimbra OSE nu dispune de un sistem de backup \u00eencorporat, va fi necesar s\u0103 folosim Zextras Backup, care suport\u0103 backup-uri \u00een timp real, \u0219i un stoc external. Av\u00e2nd \u00een vedere c\u0103 Zextras Backup, realiz\u00e2nd backup-uri complete \u0219i incrementale, salveaz\u0103 toate datele \u00een folderul \/opt\/zimbra\/backup, ar fi rezonabil s\u0103 mont\u0103m acolo un stoc extern, de re\u021bea sau chiar \u00een cloud, pentru a avea un suport cu o copie de rezerv\u0103 actualizat\u0103 la momentul incidentului \u00een caz de c\u0103dere a unui dintre servere. Aceasta poate fi desf\u0103\u0219urat\u0103 at\u00e2t pe un server fizic de rezerv\u0103, c\u00e2t \u0219i pe o ma\u0219in\u0103 virtual\u0103 sau \u00een cloud. De asemenea, ar fi o idee bun\u0103 s\u0103 instal\u0103m un MTA cu un filtru anti-spam \u00eenainte de serverul cu Zimbra Proxy, pentru a reduce cantitatea de trafic de gunoi care ajunge pe server.<\/p>\n

\u00cen concluzie, infrastructura protejat\u0103 Zimbra va ar\u0103ta aproximativ astfel:<\/p>\n

\"Planificarea
\n
\nCu aceast\u0103 configura\u021bie, infrastructura Zimbra nu numai c\u0103 va putea oferi servicii de calitate pentru 10.000 de utilizatori, dar \u00een cazul apari\u021biei unei situa\u021bii neprev\u0103zute va permite eliminarea rapid\u0103 a efectelor acesteia.
