Kao \u0161to ste mo\u017eda \u010duli, po\u010detkom o\u017eujka tvrtka Hewlett Packard Enterprise najavila je namjeru da kupi neovisnog proizvo\u0111a\u010da hibridnih i flash sustava, Nimble. Kupnja je zavr\u0161ena 17. travnja, a sada ova tvrtka 100% pripada HPE-u. U zemljama gdje je Nimble ve\u0107 bio prisutan, proizvodi Nimble dostupni su putem kanala Hewlett Packard Enterprise. U na\u0161oj zemlji, ovaj \u0107e proces potrajati du\u017ee, no mo\u017ee se o\u010dekivati da \u0107e do studenog Nimble sustavi zauzeti svoje mjesto izme\u0111u naprednijih konfiguracija MSA i 3PAR 8200.<\/p>\n

Osim integracije proizvodnje i prodajnih kanala, HPE se suo\u010dava s jo\u0161 jednim izazovom, a to je kori\u0161tenje rje\u0161enja softvera Nimble InfoSight, koji prelazi okvire isklju\u010divo sustava pohrane. Prema procjenama IDC<\/a><\/noindex>, InfoSight je vode\u0107a platforma u industriji za prediktivnu analizu stanja IT-a, a njene prednosti poku\u0161avaju kopirati drugi proizvo\u0111a\u010di. HPE trenutno ima sli\u010dan proizvod - StoreFront Remote<\/a><\/noindex>, me\u0111utim, i IDC i Gartner ocijenili su proizvod Nimble znatno vi\u0161im ocjenama u svom 'Magi\u010dnom kvadrantu All-Flash sustava' za 2016. \u0160to ga razlikuje?<\/p>\n

\nInfoSight mijenja pristup upravljanju infrastrukturom povezanoj sa sustavima pohrane. Ponekad mo\u017ee biti vrlo te\u0161ko odrediti izvor problema koji se mogu pojaviti u vezi 'virtualni stroj - poslu\u017eitelj - sustav pohrane'. Osobito ako sve te proizvode podr\u017eavaju razli\u010diti proizvo\u0111a\u010di (podsje\u0107am da u slu\u010daju HPE, usluga za Windows, VMware, poslu\u017eitelje i sustave pohrane pru\u017ea se putem jedinstvene slu\u017ebe HPE PointNext<\/a><\/noindex>). Korisniku bi bilo mnogo jednostavnije kada bi se sveobuhvatna analiza stanja infrastrukture automatski provodila na svim razinama IT-a kroz koje prolaze transakcije poslovnih aplikacija, a rezultati bi se iznosili ve\u0107 kao gotovo rje\u0161enje. I to po\u017eeljno prije nego \u0161to problem nastane. Softver Nimble InfoSight radi upravo to, omogu\u0107uju\u0107i postizanje jedinstvenih rezultata: dostupnost podataka na razini 99.999928%<\/a><\/noindex> U su\u0161tini, na sustavima osnovne razine, automatska predikcija potencijalnih problema (uklju\u010duju\u0107i one izvan sustava pohrane) mo\u017ee provesti preventivne mjere u 86% slu\u010dajeva. Bez uklju\u010divanja sistemskog administratora i poziva podr\u0161ci! Ukoliko \u017eelite potro\u0161iti manje vremena na odr\u017eavanje svog informacijskog sustava, preporu\u010dam da pa\u017eljivije pogledate InfoSight.<\/p>\n

Kako je to napravljeno?<\/h2>\n

\nJedna od klju\u010dnih razlika operativnog sustava NimbleOS je ve\u0107i broj dijagnosti\u010dkih podataka dostupnih za analizu. Tako, umjesto standardnih logova i metrika stanja sustava, prikuplja se ogromna koli\u010dina dodatnih informacija. Programeri nazivaju dijagnosti\u010dki kod \u201esenzorima\u201c, a ti senzori su integrirani u svaki modul operativnog sustava. Instalirana baza Nimble ima vi\u0161e od 10,000 korisnika, a desetci tisu\u0107a sustava povezani su s oblakom koji trenutno prikuplja 300 trilijuna pokazatelja array-a kroz godine kori\u0161tenja, i svake sekunde analizira milijune doga\u0111aja.
\nKada imate toliko statisti\u010dkih podataka, preostaje ih samo analizirati. <\/p>\n

\"Nimble<\/p>\n

Pokazuje se da se vi\u0161e od polovice problema koji uzrokuju usporavanje operacija ulazno-izlaznih poslovnih aplikacija nalazi izvan array-a<\/a><\/noindex>, a drugi proizvo\u0111a\u010di koji se bave isklju\u010divo sustavima pohrane jednostavno ne mogu adekvatno razumjeti servisni slu\u010daj u ve\u0107ini slu\u010dajeva. Uspore\u0111uju\u0107i podatke array-a s drugim dijagnosti\u010dkim informacijama, mogu\u0107e je otkriti pravi izvor problema na cijelom putu od virtualnih ma\u0161ina do diskova array-a. Evo nekoliko primjera:<\/p>\n

1. Dijagnostika performansi <\/b>\u2013 prili\u010dno slo\u017een zadatak za slo\u017eenu IT infrastrukturu. Analiza log datoteka i pokazatelja na svakoj razini sustava mo\u017ee potrajati puno vremena. InfoSight, temeljen na korelaciji brojnih pokazatelja, mo\u017ee odrediti gdje dolazi do usporavanja \u2013 na serveru, u mre\u017ei prijenosa podataka ili u sustavu pohrane. Mogu\u0107e je da je problem u susjednoj virtualnoj ma\u0161ini, mo\u017eda je konfiguracija mre\u017ene opreme napravljena s gre\u0161kama, ili bi moglo biti potrebno optimizirati postavke servera.<\/p>\n

2. Nevidljivi problemi.<\/b> Odre\u0111eni niz indikatora \u010dini potpis koji predvi\u0111a kako \u0107e se sustav pona\u0161ati u budu\u0107nosti. Vi\u0161e od 800 potpisa prati softver InfoSight u stvarnom vremenu, \u0161to omogu\u0107uje otkrivanje problema izvan samog skladi\u0161ta. Na primjer, kod jednog od klijenata nakon nadogradnje operativnog sustava SANI do\u0161lo je do deset puta smanjenja performansi, uzrokovanog specifi\u010dnostima rada hipervizora. Na temelju ovog slu\u010daja nije samo izdan zakrpa, nego je automatski spre\u010dena pojava sli\u010dne situacije kod jo\u0161 600 sustava za pohranu, jer je potpis odmah dodan u oblak InfoSight.<\/p>\n

Umjetna inteligencija<\/h2>\n

\nMo\u017eda je to previ\u0161e glasna izjava za opis rada InfoSight-a, ali napredni statisti\u010dki algoritmi i predikcije zasnovane na njima su klju\u010dna prednost platforme. Algoritmi koje koristi platforma uklju\u010duju autoregresivne modele prognoziranja i simulaciju metodom Monte Carlo, \u0161to omogu\u0107uje predvi\u0111anje \u2018slu\u010dajnih\u2019 doga\u0111aja koji se na prvi pogled mogu \u010diniti nasumi\u010dnima.<\/p>\n

\"Nimble<\/p>\n

Podaci o trenutnom stanju infrastrukture omogu\u0107uju precizno veli\u010danje i za modernizaciju informati\u010dkog sustava. Od trenutka implementacije novih komponenti, InfoSight prikuplja podatke za daljnju analizu, a matemati\u010dki model postaje jo\u0161 to\u010dniji.
\nPlatforma se neprekidno u\u010di na instaliranoj bazi koja je stvorena kod klijenata tijekom godina postojanja tvrtke Nimble, i u\u010di kako bi podr\u0161ka sustavima \u2013 sada ve\u0107 Hewlett Packard Enterprise \u2013 postala jednostavnijim i jasnijim zadatkom. Broj samo 3PAR skladi\u0161ta koja trenutno rade kod klijenata zna\u010dajno prema\u0161uje sli\u010dne pokazatelje Nimble. Stoga \u0107e podr\u0161ka InfoSight-u za 3PAR stvoriti jo\u0161 potpuniju sliku za statisti\u010dku analizu IT infrastrukture. Naravno, bit \u0107e potrebne modifikacije u 3PAR OS, ali s druge strane, nije sve \u0161to je ugra\u0111eno u InfoSight jedinstveno samo za ovu platformu. Stoga o\u010dekujemo vijesti od objedinjene razvojne ekipe Hewlett Packard Enterprise i Nimble!<\/p>\n
