Zextras PowerStore jedan je od najtra\u017eenijih dodataka za Zimbra Collaboration Suite unutar Zextras Suite. Kori\u0161tenje ovog pro\u0161irenja, koje omogu\u0107uje hijerarhijsko upravljanje pohranom unutar Zimbre, kao i zna\u010dajno smanjenje prostora na tvrdom disku koje zauzimaju korisni\u010dki ra\u010duni putem kori\u0161tenja algoritama kompresije i deduplikacije, na kraju dovodi do zna\u010dajnog smanjenja tro\u0161kova vlasni\u0161tva \u010ditave infrastrukture Zimbra. A kada se Zextras PowerStore koristi u uvjetima SaaS pru\u017eatelja, tada se mo\u017ee govoriti o golemim u\u0161tedama. No, to nisu sve mogu\u0107nosti koje ovo pro\u0161irenje mo\u017ee ponuditi administratoru Zimbre. Kako bismo saznali \u0161to jo\u0161 Zextras PowerStore mo\u017ee ponuditi administratoru Zimbre, obratili smo se Luca Arcara<\/b>, vi\u0161em konzultantu za rje\u0161enja u Zextrasu, koji aktivno sudjeluje u razvoju Zextras Suite. Naveo nam je \u010detiri klju\u010dne mogu\u0107nosti Zextras PowerStore koje \u0107e se svidjeti svakom administratoru Zimbre.<\/p>\n

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

4. Mogu\u0107nost prilagodbe pohrane nakon instalacije Zimbre<\/b><\/p>\n

U pro\u0161lom \u010dlanku govorili smo o tome kako optimizirati po\u0161tanske pohrane Zimbre kako bi pokazale maksimalne performanse. Osim \u0161to administrator Zimbra Collaboration Suite Open-Source Edition treba odabrati veli\u010dine po\u0161tanskih pohrana ve\u0107 u fazi projektiranja infrastrukture, jedna od preporuka bila je pa\u017eljivo pristupiti izboru broja bajtova za inode, koji se formira na tvrdom disku pomo\u0107u alata mke2fs i parametra -i prilikom kreiranja datote\u010dnog sustava.<\/p>\n

Me\u0111utim, da bi se to\u010dno odredila prosje\u010dna veli\u010dina poruka u fazi projektiranja, sistemskom administratoru potreban je dar nadgledanja. Naravno, takav dar imaju samo rijetki, a interni parametri poput prosje\u010dnog volumena poruke i veli\u010dine pohrane svakako je bolje rje\u0161avati uz dostupnu statistiku rada Zimbre u 'borbenim' uvjetima. <\/p>\n

I ovdje Zimbra administratoru poma\u017ee pro\u0161irenje Zextras PowerStore, koje, zahvaljuju\u0107i mogu\u0107nosti kori\u0161tenja hijerarhijskog upravljanja ure\u0111ajima, omogu\u0107uje povezivanje dodatnog spremnika i time odga\u0111a dono\u0161enje odluka o prosje\u010dnoj veli\u010dini poruka i koli\u010dinama podatkovnih ure\u0111aja do pojave potpune statistike.<\/p>\n

3. Mogu\u0107nost izbjegavanja kori\u0161tenja LVM-a<\/b><\/p>\n

Upravitelj logi\u010dkih volumena, iako je odli\u010dan alat koji na prvi pogled savr\u0161eno odgovara po\u0161tanskom skladi\u0161tu Zimbra zahvaljuju\u0107i mogu\u0107nosti pro\u0161irenja i snimanja snapshot-a, ipak ima brojne nedostatke. Klju\u010dni su kompliciranije upravljanje volumenima u usporedbi s obi\u010dnim diskovima, kao i visoka vjerojatnost kvara cijelog LVM-a u slu\u010daju o\u0161te\u0107enja jednog od fizi\u010dkih ure\u0111aja, \u0161to je prili\u010dno kriti\u010dno kada se radi o velikim instalacijama Zumbre.<\/p>\n

Zextras PowerStore, s druge strane, omogu\u0107uje izbjegavanje kori\u0161tenja LVM-a i pru\u017ea mogu\u0107nost pro\u0161irenja dostupnog kapaciteta povezivanjem obi\u010dnih tvrdih diskova. To administratoru Zimbre omogu\u0107uje maksimalno pojednostavljenje upravljanja ure\u0111ajima, a time i optimizaciju procesa njihove rezervacije, \u010dime se \u010ditava infrastruktura \u010dini otpornijom na kvarove.<\/p>\n

2. Mogu\u0107nost premje\u0161tanja podataka na druge volumene i ure\u0111aje<\/b><\/p>\n

Svaku problem uvijek je bolje sprije\u010diti nego kasnije rje\u0161avati njegove posljedice. Ovo pravilo je sasvim opravdano za situaciju kada do\u0111e do kvara tvrdog diska i prate\u0107eg potpune ili djelomi\u010dne gubitka podataka. Planirana zamjena ure\u0111aja informacijama je prili\u010dno uobi\u010dajena praksa me\u0111u SaaS pru\u017eateljima, kojima je lak\u0161e unaprijed planirati preventivnu pauzu i obavijestiti klijente o tome nego snositi gubitke i kvariti svoj imid\u017e zbog nepravodobnog kvara tvrdog diska.<\/p>\n

\u010cini se da nema ni\u0161ta jednostavnije od premje\u0161tanja podataka s jednog tvrdog diska na drugi. U normalnim uvjetima to se obavlja pomo\u0107u alata dd, koji dolazi s bilo kojim distribucijom Linuxa. Me\u0111utim, nije sve tako jednostavno. Osim podataka, dd pa\u017eljivo prenosi na novi disk sve postavke starog datote\u010dnog sustava i onemogu\u0107uje vam da ih promijenite. Tako\u0111er, ako su na disk na bilo koji na\u010din dospjeli rootkitovi i drugi potencijalno opasni virusi, dd \u0107e tako\u0111er pa\u017eljivo prenijeti njih na novi tvrdni disk. Upravo iz tog razloga, pri planiranoj zamjeni diska, najbolji na\u010din za premje\u0161tanje po\u0161tanskih kutija s jednog diska na drugi je kori\u0161tenje Zextras PowerStore. Njegovom upotrebom, Zimbra administrator dobiva mogu\u0107nost da prenese na novi disk samo najva\u017enije \u2014 po\u0161tanske kutije i njihov sadr\u017eaj, uz slobodu u postavljanju datote\u010dnog sustava na njemu.<\/p>\n

Tako\u0111er, u bilo kojoj visoko optere\u0107enoj infrastrukturi, bilo da se radi o velikom poduze\u0107u ili SaaS pru\u017eatelju, postoje i po\u0161tanske kutije kojima bi se trebao pristupiti neprekidno. To se odnosi na po\u0161tanske kutije vi\u0161ih menad\u017eera, po\u0161tanske kutije za upite od klijenata i tako dalje. Kori\u0161tenjem standardne verzije, premje\u0161tanje pojedina\u010dne po\u0161tanske kutije iz spremnika koji se zatvara na odr\u017eavanje na server<\/a>, koji nastavlja raditi, nije mogu\u0107e. Izbje\u0107i prekid rada tijekom odr\u017eavanja po\u0161tanskog spremnika u kojem se nalaze takve kutije, tako\u0111er je mogu\u0107e pomo\u0107u pro\u0161irenja Zextras PowerStore, koje omogu\u0107ava premje\u0161tanje pojedina\u010dnih kutija izme\u0111u po\u0161tanskih spremnika unutar iste Zimbra infrastrukture. Tako Zextras PowerStore mo\u017ee pomo\u0107i Zimbra administratoru da pove\u0107a sigurnost i znatno smanji vrijeme zastoja prilikom manipulacije tvrdim diskovima.<\/p>\n

Osim toga, Zextras PowerStore mo\u017ee pomo\u0107i pri spa\u0161avanju podataka s djelomi\u010dno o\u0161te\u0107enog diska. Programeri su osigurali mogu\u0107nost ignoriranja gre\u0161aka u \u010ditanju prilikom premje\u0161tanja po\u0161tanskih kutija, stoga u niz situacija, kada je medij s podacima ve\u0107 po\u010deo pokazivati lo\u0161e blokove, zahvaljuju\u0107i PowerStoreu, administrator i dalje ima mogu\u0107nost spa\u0161avanja ve\u0107ine informacija s njega.<\/p>\n

1. Mogu\u0107nost povezivanja objektnih spremi\u0161ta<\/b><\/p>\n

Glavna zna\u010dajka Zextras PowerStore koju Luca Arcara isti\u010de je mogu\u0107nost vru\u0107eg povezivanja objektnih skladi\u0161ta s infrastrukturom Zimbre, \u0161to administratoru omogu\u0107ava gotovo trenutni pristup svim prednostima kori\u0161tenja kako oblaka, tako i lokalno implementiranih servisa.<\/p>\n

S obzirom na to da mnogi cloud pru\u017eatelji trenutno nude pristup svojim skladi\u0161tima putem modela pretplate, administratorima Zimbre se otvaraju beskrajne mogu\u0107nosti za rezerviranje i skaliranje svoje infrastrukture, kao i realizaciju hardverske redundantnosti po vrlo razumnim cijenama.<\/p>\n

Osim toga, mogu\u0107nost pohrane dijela podataka u oblaku ili u teritorijalno udaljenim skladi\u0161tima omogu\u0107ava br\u017ee obnavljanje funkcionalnosti Zimbre u slu\u010daju bilo kakvih velikih incidenata, \u0161to zna\u010dajno pove\u0107ava sigurnost kori\u0161tenja ovog rje\u0161enja u poduze\u0107u.
