Solu\u021biile hiperconvergente au fost p\u00e2n\u0103 recent neadecvate pentru baze de date, mai ales cu \u00eenc\u0103rcare mare.

Introducere<\/h3>\n

\n\u00cen prezent, exist\u0103 dou\u0103 abord\u0103ri pentru organizarea solu\u021biilor hiperconvergente. Prima abordare se bazeaz\u0103 pe solu\u021bii Software-defined, care sunt livrate ca software, iar echipamentele sunt selectate de clien\u021bi. A doua abordare se bazeaz\u0103 pe solu\u021bii \u201ela cheie\u201d, care con\u021bin at\u00e2t software, c\u00e2t \u0219i echipamente, \u0219i suport tehnic. La Cisco, ne men\u021binem pe a doua abordare \u0219i livr\u0103m solu\u021bii gata preparate clien\u021bilor no\u0219tri, deoarece doar \u00een acest mod putem garanta comportamentul stabil al sistemului, suport tehnic de calitate din partea unui singur furnizor \u0219i performan\u021b\u0103 ridicat\u0103.
\nPerforman\u021ba ridicat\u0103 a sistemului este unul dintre factorii cheie \u00een luarea deciziilor privind utilizarea unui anumit produs \u00een sarcini critice. <\/p>\n

Ast\u0103zi, organiza\u021biile, de obicei, \u00ee\u0219i desf\u0103\u0219oar\u0103 sarcinile critice pe solu\u021bii tradi\u021bionale cu arhitectur\u0103 pe trei niveluri (stocare > re\u021bea de stocare > servere). \u00cen acela\u0219i timp, majoritatea organiza\u021biilor caut\u0103 s\u0103 simplifice \u0219i s\u0103 reduc\u0103 costurile infrastructurii IT, f\u0103r\u0103 a compromite stabilitatea \u0219i performan\u021ba acesteia. Din acest motiv, clien\u021bii acord\u0103 din ce \u00een ce mai mult\u0103 aten\u021bie solu\u021biilor hiperconvergente. <\/p>\n

\u00cen cadrul acestui articol, vom discuta despre cele mai recente teste (februarie 2019), efectuate de laboratorul independent ESG (Enterprise Strategy Group). \u00cen timpul test\u0103rii, a fost simulat\u0103 func\u021bionarea bazelor de date Oracle \u0219i MS SQL cu \u00eenc\u0103rcare mare (teste OLTP), ceea ce reprezint\u0103 unul dintre cele mai critice componente ale infrastructurii IT \u00een medii productive reale. <\/p>\n

Aceast\u0103 sarcin\u0103 a fost efectuat\u0103 pe trei solu\u021bii: Cisco Hyperflex, precum \u0219i dou\u0103 solu\u021bii software-defined, care au fost instalate pe acelea\u0219i servere utilizate \u00een Hyperflex, adic\u0103 pe serverele Cisco UCS.<\/p>\n

Configura\u021bii de testare<\/h3>\n

\n\"Cisco<\/p>\n

\u00cen sistemul vendorului A, nu se utilizeaz\u0103 cache, deoarece configura\u021bia cu cache nu este suportat\u0103 de dezvoltatorul solu\u021biei. Din acest motiv, au fost folosite discuri pentru stocarea unui volum mai mare.<\/p>\n

Metodologia de testare<\/h3>\n

\nTestele OLTP au fost efectuate cu patru ma\u0219ini virtuale \u0219i un set de date de 3,2 TB. \u00cenainte de fiecare test, fiecare MV a fost umplut\u0103 cu datele \u00eenregistrate prin intermediul instrumentului de testare. Aceasta garanteaz\u0103 c\u0103 testul cite\u0219te date 'reale' \u0219i le scrie \u00een blocurile existente, nu doar returneaz\u0103 blocuri nule sau valori nule direct din memorie. Acest lucru se \u00eent\u00e2mpl\u0103 c\u00e2nd datele nu sunt umplute, a\u0219a c\u0103 a fost important s\u0103 ne asigur\u0103m c\u0103 testul reflect\u0103 exact modul \u00een care datele sunt citite \u0219i scrise \u00een mediu aplica\u021bia. Umplerea acestui set de lucru mare a durat un timp \u00eendelungat, dar din punctul nostru de vedere, a fost o investi\u021bie productiv\u0103 de timp, deoarece permite ob\u021binerea unor date de performan\u021b\u0103 mai precise.<\/p>\n

Testarea a fost efectuat\u0103 folosind instrumentul HCI Bench (bazat pe Oracle Vdbench) \u0219i profile de intrare-ie\u0219ire, destinate emul\u0103rii sarcinilor de lucru OLTP critice complexe, utiliz\u00e2nd backend-uri Oracle \u0219i SQL Server. Dimensiunile blocurilor au fost alese \u00een conformitate cu aplica\u021biile emulate, av\u00e2nd acces 100% aleatoriu la date (full random). <\/p>\n

Sarcina de lucru Oracle Database<\/h3>\n

\nPrimul test realizat a fost testul OLTP, dezvoltat pentru a emula mediu Oracle. Vdbench a fost folosit pentru a crea o \u00eenc\u0103rcare de lucru cu diverse raporturi de citire \u0219i scriere. Testul a fost efectuat pe patru ma\u0219ini virtuale. \u00cen timpul testului de patru ore, HyperFlex a reu\u0219it s\u0103 arate peste 420.000 IOPS cu un timp de \u00eent\u00e2rziere de doar 4,4 milisecunde. Solu\u021biile software A \u0219i B au reu\u0219it s\u0103 arate doar 238.000 \u0219i respectiv 251.000 IOPS.<\/p>\n

\"Cisco<\/p>\n

\"Cisco
\nNivelul \u00eent\u00e2rzierilor \u00een diferite sisteme a fost aproximativ acela\u0219i, cu excep\u021bia \u00eent\u00e2rzierii de scriere pentru furnizorul B, care a fost \u00een medie de 26,49 ms, av\u00e2nd \u00een acela\u0219i timp performan\u021be foarte bune pe citire, de 2,9 ms. Compresia \u0219i deduplicarea au fost active \u00een toate sistemele.<\/p>\n

\u00cenc\u0103rcarea de lucru Microsoft SQL Server<\/h3>\n

\nApoi a fost analizat\u0103 \u00eenc\u0103rcarea de lucru OLTP, destinat\u0103 s\u0103 emuleze SGBD-ul Microsoft SQL Server. <\/p>\n

\"Cisco
\nCa rezultat al acestui test, clusterul Cisco HyperFlex a dep\u0103\u0219it de aproximativ dou\u0103 ori pe ambii concuren\u021bi A \u0219i B. 490.000 IOPS pentru Cisco comparativ cu 200.000 \u0219i 260.000 pentru produc\u0103torii A \u0219i B.<\/p>\n

\"Cisco
\nRezultatul \u00eent\u00e2rzierilor \u00een Cisco HyperFlex nu a fost semnificativ diferit de testul Oracle, adic\u0103 a fost la un nivel bun de 4,4 ms. Totu\u0219i, produc\u0103torii A \u0219i B au ar\u0103tat rezultate semnificativ mai slabe dec\u00e2t \u00een testul pentru Oracle. Singurul aspect pozitiv pentru solu\u021bia concurent\u0103 B este nivelul constant sc\u0103zut al \u00eent\u00e2rzierilor la citire, de 2,9 ms, \u00een timp ce pentru celelalte criterii, HyperFlex a dep\u0103\u0219it solu\u021biile concurente de dou\u0103 ori \u0219i mai mult.<\/p>\n

Conclusions<\/h3>\n

\nTestarea realizat\u0103 de laboratorul independent ESG a confirmat \u00eenc\u0103 o dat\u0103 nivelul de performan\u021b\u0103 remarcabil al solu\u021biei Cisco Hyperflex, demonstr\u00e2nd c\u0103 sistemele hiperconvergente sunt deja preg\u0103tite pentru utilizare pe scar\u0103 larg\u0103 \u00een sarcini critice.<\/p>\n

Sistemele hiperconvergente au fost considerate mult timp mai potrivite pentru sarcini non-critice. \u00cen 2016, ESG a realizat un sondaj printre mari companii. Ace\u0219tia au fost \u00eentreba\u021bi de ce au preferat infrastructura tradi\u021bional\u0103 \u00een loc de cea hiperconvergent\u0103. 54% dintre responden\u021bi au r\u0103spuns c\u0103 motivul este performan\u021ba. <\/p>\n

S\u0103 ne mut\u0103m \u00een 2018. Situa\u021bia s-a schimbat: un sondaj repetat ESG a relevat acum doar 24% dintre responden\u021bi care mai cred c\u0103 abord\u0103rile tradi\u021bionale sunt \u00eenc\u0103 mai bune din punct de vedere al performan\u021bei.<\/p>\n

Atunci c\u00e2nd evolu\u021bia tehnologiilor schimb\u0103 criteriile de alegere a solu\u021biilor din industrie, adesea apare o nepotrivire \u00eentre ceea ce doresc clien\u021bii \u0219i ceea ce pot ob\u021bine. Produc\u0103torii care pot observa ce lipse\u0219te \u0219i umple aceast\u0103 gol sunt cei care ob\u021bin un avantaj. Cisco ofer\u0103 o solu\u021bie hiperconvergent\u0103 care asigur\u0103 simplificare \u0219i economie, precum \u0219i o performan\u021b\u0103 constant ridicat\u0103, care este esen\u021bial\u0103 pentru clien\u021bi \u00een cazul sarcinilor de munc\u0103 critice. <\/p>\n

Compania Cisco \u00eenainteaz\u0103 constant \u00een domeniul sistemelor hiperconvergente, ceea ce este confirmat nu doar prin caracteristicile excelente ale solu\u021biei Cisco Hyperflex, ci \u0219i prin prezen\u021ba sa pe pia\u021b\u0103. Astfel, \u00een toamna anului 2018, Cisco a intrat pe merit \u00een grupul liderilor pie\u021bei HCI conform versiunii Gartner.<\/p>\n

\"Cisco
\nDeja acum, pute\u021bi confirma c\u0103 Hyperflex este o solu\u021bie excelent\u0103 pentru cele mai complexe \u0219i solicitante sarcini de afaceri, vizit\u00e2nd demonstra\u021biile noastre care vor avea loc \u00een ora\u0219ele Moscova \u0219i Krasnodar.<\/p>\n
