Utilizarea unit\u0103\u021bilor de stocare pe baz\u0103 de solide (SSD) nu mai surprinde pe nimeni \u00een domeniul stoc\u0103rii de date. SSD-urile au devenit o parte integrant\u0103 a echipamentelor IT, de la computere personale \u0219i laptopuri p\u00e2n\u0103 la servere \u0219i sisteme de stocare a datelor. Pe parcursul acestui timp, au existat mai multe genera\u021bii de SSD-uri, fiecare av\u00e2nd caracteristici \u00eembun\u0103t\u0103\u021bite \u00een ceea ce prive\u0219te performan\u021ba, fiabilitatea \u0219i capacitatea maxim\u0103.

Datorit\u0103 structurii lor fizice, unit\u0103\u021bile de stocare pe baz\u0103 de solide au o resurs\u0103 de scriere limitat\u0103 din start. Faptul c\u0103 pe SSD se scriu de fapt mult mai multe date dec\u00e2t sunt trimise de host (\u00een special ca parte a unui grup RAID) ne apropie \u0219i mai mult de acest limit\u0103. Aceast\u0103 situa\u021bie reprezint\u0103 o fric\u0103 pentru unii utilizatori \u00een utilizarea SSD-urilor.<\/p>\n

<\/p>\n

\u00cen realitate, lucrurile nu stau at\u00e2t de r\u0103u. Resursa estimat\u0103 DWPD este calculat\u0103 pentru \u00eentreaga perioad\u0103 de garan\u021bie a unit\u0103\u021bii (de obicei, 3-5 ani). A\u0219adar, resursa real\u0103 de scriere TBW va fi destul de impresionant\u0103, ceea ce permite utilizatorilor s\u0103 nu se team\u0103 c\u0103 vor \u201eepuiza\u201d SSD-ul \u00een doar c\u00e2teva luni. Mai mult, \u00een anumite cazuri, este posibil s\u0103 folosi\u021bi temporar unit\u0103\u021bile \u00eentr-un mod mai intensiv dec\u00e2t este prev\u0103zut de produc\u0103tor, datorit\u0103 valorilor mari TBW. Cu toate acestea, toate acestea nu elimin\u0103 necesitatea monitoriz\u0103rii resursei de scriere curente a fiec\u0103rui SSD \u00een scopul unei \u00eenlocuiri proactive atunci c\u00e2nd se ating anumite praguri.<\/p>\n

<\/p>\n

Fiecare vendor de SCD implementeaz\u0103 aceast\u0103 func\u021bionalitate \u00een mod diferit. Dar cel mai adesea, aceasta const\u0103 pur \u0219i simplu \u00een starea unit\u0103\u021bii, func\u021bional\u0103\/nefunc\u021bional\u0103. Qsan<\/a><\/noindex> \u00een sistemele sale All Flash<\/a><\/noindex>, pe de alt\u0103 parte, a realizat o vizualizare complet\u0103 a parametrilor activit\u0103\u021bii curente a SSD-urilor sub form\u0103 de modul separat numit QSLife. Acest modul este o parte integrant\u0103 a noului sistem de operare XEVO<\/a><\/noindex>, sub gestionarea c\u0103ruia vor func\u021biona \u00een viitor toate SCD-urile Qsan.<\/p>\n

<\/p>\n

Pentru fiecare SSD din sistem, nivelul actual de \u201edurabilitate\u201d este afi\u0219at \u00eentr-o form\u0103 maxim\u0103 accesibil\u0103. Nu este un secret c\u0103 toate SSD-urile moderne \u00ee\u0219i \u021bin propriile eviden\u021be ale blocurilor scrise pe ele. Pe baza acestor valori, sistemul calculeaz\u0103 indicatorul de uzur\u0103 al unit\u0103\u021bii \u00een conformitate cu parti\u021bionarea sa. Rezultatul final este afi\u0219at sub form\u0103 de procente dintr-un SSD complet nou. De asemenea, men\u021bion\u0103m c\u0103 gradul de uzur\u0103 este calculat nu doar pentru perioada \u00een care unitatea a lucrat \u00een cadrul unui array All Flash Qsan, ci pentru \u00eentreaga sa durat\u0103 de via\u021b\u0103, inclusiv utilizarea \u00een alte sisteme (dac\u0103 a fost cazul).<\/p>\n

<\/p>\n

\"Monitorizarea<\/p>\n

\u00cen plus fa\u021b\u0103 de informa\u021biile simplificate despre unitate, se pot ob\u021bine \u0219i c\u00e2teva detalii. \u00cen special, volumul datelor scrise pe ea pe \u00eentreaga durat\u0103 de via\u021b\u0103. Iar pentru perioada \u00een care unitatea a lucrat \u00een cadrul All Flash array-ului Qsan<\/a><\/noindex>, sunt disponibile grafice ale activit\u0103\u021bii sale \u00een opera\u021bii de citire \u0219i scriere. Statistica este adunat\u0103 \u00een timp real \u0219i este disponibil\u0103 pentru orice perioad\u0103, cu o ad\u00e2ncime de vizualizare de p\u00e2n\u0103 la un an.<\/p>\n

<\/p>\n

\"Monitorizarea<\/p>\n

Desigur, scopul acestei func\u021bionalit\u0103\u021bi nu este doar de a construi grafice frumoase pentru a \u00eenc\u00e2nta administratorul, ci \u0219i de a analiza proactiv starea unit\u0103\u021bilor \u0219i de a preveni problemele poten\u021biale \u00een viitor legate de uzura acestora. De aceea, pentru \u201enivelul de durabilitate\u201d al SSD-ului se pot stabili numeroase praguri \u0219i ac\u021biuni corespunz\u0103toare \u00een leg\u0103tur\u0103 cu epuizarea resurselor de scriere ale SSD-ului.<\/p>\n

<\/p>\n

\"Monitorizarea<\/p>\n

Dac\u0103 ne uit\u0103m la alte modele de storage (nu cele specializate All Flash, ci cele de uz general) de la Qsan<\/a><\/noindex>, atunci acestea nu au un raport vizualizat similar pentru unit\u0103\u021bi. Este de \u00een\u021beles: p\u00e2n\u0103 la urm\u0103, un flagship trebuie s\u0103 se deosebeasc\u0103 de mainstream. Totu\u0219i, \u00een gama regulat\u0103 de produse se efectueaz\u0103 un astfel de monitorizare. Da, f\u0103r\u0103 colectarea statisticilor privind utilizarea \u0219i performan\u021ba. Dar func\u021bia principal\u0103 de urm\u0103rire a resurselor de scriere este prezent\u0103.<\/p>\n

<\/p>\n

\"Monitorizarea<\/p>\n

Odat\u0103 cu \u00eembun\u0103t\u0103\u021birea constant\u0103 a tehnologiilor de produc\u021bie a unit\u0103\u021bilor de stocare cu stare solid\u0103, problema fiabilit\u0103\u021bii acestora a devenit mai pu\u021bin acut\u0103. Cu toate acestea, monitorizarea resurselor de scriere r\u0103m\u00e2ne relevant\u0103. Un astfel de sistem de monitorizare configurat corespunz\u0103tor va permite administratorului s\u0103 prezic\u0103 din timp \u00eemb\u0103tr\u00e2nirea SSD-ului \u00een func\u021bie de sarcinile curente reale, iar conducerii companiei s\u0103 calculeze indicatorii TCO (costul total de proprietate).<\/p><\/blockquote>\n
