Exadata piyasayada \u00f6zellikle konsolidasyon ve lisans maliyetlerini d\u00fc\u015f\u00fcrme motivasyonuyla tutuldu. \u00c7al\u0131\u015ft\u0131\u011f\u0131m kurumlarda yada gitti\u011fim bir \u00e7ok Banka,Sigorta ve Telekom\u00fcnikasyon m\u00fc\u015fterilerim de g\u00f6rd\u00fcm ki boyutu s\u00fcrekli olarak artan veriler i\u00e7in al\u0131nan Server ve Storagelarda bir s\u00fcre sonra Data centerlara da s\u0131\u011fmamaktad\u0131r.<\/p>\n

Fiziki olarak birden fazla kabinetin tek bir kabinete d\u00f6n\u00fc\u015ft\u00fcr\u00fclebilir olmas\u0131 hem\u00a0 Data center da yer a\u00e7acakt\u0131r hem elektrik so\u011futma giderlerini azaltacakt\u0131r. Fakat i\u015fin bizi ilgilendiren k\u0131sm\u0131nda en \u00f6nemlisi lisans ve donan\u0131m maliyetlerini azaltacak olmas\u0131d\u0131r.<\/p>\n

A\u015fa\u011f\u0131da basit\u00e7e \u00e7izimle g\u00f6stermeye \u00e7al\u0131\u015ft\u0131\u011f\u0131m gibi 4-5 farkl\u0131 veritabanlar\u0131n\u0131z i\u00e7in 4 ayr\u0131 Server ve Storage bulundurmaktansa tek bir Exadatada (1\/4 konfigde yada maximum 1\/2 konfigde) bunlar\u0131 \u00e7ok rahat konsolide edip Daha az CPU ( %30-50 ye kadar CPU tasarufu ) ve Memory ile y\u00f6netebilirsiniz.<\/p>\n

Exadata ile Konsolidasyonda CPU,RAM ve Diskten kazan\u00e7 sa\u011flad\u0131\u011f\u0131n\u0131z gibi y\u00f6netimi de ayn\u0131 \u015fekilde daha kolay bir hale gelmektedir. Eskiden Database Administrator dedi\u011fimiz DBA ler bu i\u015fin y\u00f6netimini yaparken Exadata ile beraber Database Machine Administrator dedi\u011fimiz Exadata DMA pozisyonu ortaya \u00e7\u0131kt\u0131. Yeni d\u00f6nemde Exadata DMA yi hem Veritaban\u0131n\u0131n y\u00f6netiminden hem Linux Sistem y\u00f6netiminden hemde Storage \u0131n y\u00f6netiminden sorumlu oldu\u011fu i\u00e7in bir \u00e7ok kurumda Exadata ya bakacak Storage yada Sistemciye art\u0131k ihtiya\u00e7 duyulmamaktad\u0131r.<\/p>\n

Oracle X5-2 \u00f6ncesinde satt\u0131\u011f\u0131 Exadata \u00fcst\u00fcnde ka\u00e7 core varsa o kadar Enterprise lisansla lisansland\u0131r\u0131yordu.\u00a0 \u00d6rne\u011fin X4-2 versiyonun 1\/8 konfig\u00fcrasyonunda 24 Core vard\u0131, bu exadatay\u0131 lisansland\u0131r\u0131rken 24 Core a g\u00f6re Lisanslayan oracle, X5 le beraber art\u0131k capacity on demand dedi\u011fimiz modele ge\u00e7ti ve makinalarda Core olmas\u0131na ra\u011fmen deployment yap\u0131l\u0131rken art\u0131k minimum 8 olmak \u00fczere siz se\u00e7im yap\u0131p ba\u015ftan d\u00fc\u015f\u00fckle ba\u015flay\u0131p sonras\u0131nda ihtiya\u00e7 olduk\u00e7a art\u0131\u015fa gidebiliyorsunuz.<\/p>\n

Bu modelle beraber Oracle art\u0131k Orta ve b\u00fcy\u00fck \u00f6l\u00e7ekli kurumlar\u0131n yan\u0131nda k\u00fc\u00e7\u00fck \u00f6l\u00e7ekli kurumlara da sat\u0131\u015f yapmay\u0131 ba\u015fard\u0131.

\"\"<\/p>\n

Exadata y\u0131 genel kal\u0131plar\u0131yla anlatt\u0131m art\u0131k detaylara ge\u00e7ebiliriz.<\/p>\n

\u00d6nceki yaz\u0131mda da belirtmi\u015ftim Exadata 42U luk bir kabinette fiziksel olarak Database Machine, Storage Server ve Infiniband dan ve network donan\u0131m kablolar\u0131nda olu\u015fur. \u015eimdi bunlar\u0131 detayl\u0131 inceleyelim.<\/p>\n

Database Machine<\/strong><\/p>\n

Compute node olarakta bilinen Database machine \u00fcst\u00fcnde Grid Infrastructure ve Oracle Database Software inin \u00e7al\u0131\u015ft\u0131\u011f\u0131 Veritaban\u0131 sunucusudur.<\/p>\n

\"\"<\/p>\n

Exadata X7-2 versiyonu i\u00e7in anlatacak olursam her bir database server \u0131nda 2×24 Core CPU, 384GB RAM (1.5TB a kadar artabilmektedir.) ve 40Gb \/ second Infiniband destekli network giri\u015fi(Di\u011fer Database nodelar\u0131na ve Storage serverlar\u0131na ba\u011flanabilen) ve Public eri\u015fim i\u00e7in 10 Gigabit yada 25 Gigabit networku sa\u011flayabilen network giri\u015fleri bulunmaktad\u0131r.<\/p>\n

Exadata Database machine \u0131na kurulan Grid Infrastructure RAC ve Oracle database software i Exadata ya \u00f6zel de\u011fildir. Normal sunuculara i\u00e7in yay\u0131nlanan softwareler aynen exadata i\u00e7inde ge\u00e7erlidir.<\/p>\n

Ayr\u0131ca A\u015fa\u011f\u0131da da g\u00f6r\u00fcld\u00fc\u011f\u00fc gibi Exadata \u00fcst\u00fcnde RAC kullan\u0131m\u0131\u00a0 tavsiye edilse de Single Instance da kurulup kullan\u0131labilir. Yada RAC lisans\u0131 olmayan m\u00fc\u015fteriler Exadata kullan\u0131p RAC lisans\u0131 \u00f6demeden single Instance olarak kullanabilirler.<\/p>\n

\"\"<\/p>\n

Infiniband Network<\/strong><\/p>\n

Infiniband Network, Database Server ile Storage Server aras\u0131nda ileti\u015fimi sa\u011flayan \u00a040 Gb\/sec h\u0131z\u0131nda her y\u00f6nde aktif-aktif olan y\u00fcksek performansl\u0131 \u00e7ok d\u00fc\u015f\u00fck gecikmeli bir network katman\u0131d\u0131r.\u00a0 Full ve yar\u0131m Exadata da 1 ana ve 2 yard\u0131mc\u0131 olmak \u00fczere 3 ayr\u0131 Switch gelir. \u00c7eyrek ve 1\/8 de ise sadece 2 yard\u0131mc\u0131 Switch gelir.<\/p>\n

Bu Network Database Server ve Cell aras\u0131ndaki interconnect i sa\u011flar.<\/p>\n

\"\"<\/p>\n

Exadata database machine \u0131 ve Infiniband Switches \u0131 genel olarak bahsettim, fakat Exadata n\u0131n as\u0131l sihri yada Exadata y\u0131 Exadata yapan fakt\u00f6r Database server \u0131 de\u011filde Storage server \u0131d\u0131r. B\u00fct\u00fcn Exadata \u00f6zellikleri storage server \u0131nda \u00e7al\u0131\u015fmaktad\u0131r.<\/p>\n

O y\u00fczden bundan sonraki bir ka\u00e7 makaleyi tamamen Storage Server a ay\u0131r\u0131yor olaca\u011f\u0131m. Bu yaz\u0131m\u0131n sonuna geldim umar\u0131m bu ilk 2 makaleyle Exadata nedir, neden Exadata gibi sorulara genel olarak yan\u0131t bulmu\u015fsunuzdur. Bundan sonraki makalelerde daha detayl\u0131 Exadata y\u0131 irdeliyor olaca\u011f\u0131z. \u015eimdilik esen kal\u0131n.<\/p>\n
