描述

DKC02.3-100-7-FW

?對于內(nèi)存數(shù)據(jù)庫來說,NVDIMM的作用與電池供電型RAM是類似的,但沒有后者所需的電池及其缺點。McObject公司以前就做過這方面的努力,其eXtremeDB內(nèi)存數(shù)據(jù)庫系統(tǒng)可以與電池供電型RAM一起工作。公司很想將使用NVDIMM的內(nèi)存數(shù)據(jù)庫系統(tǒng)作為主要存儲器。目前有多家供應商可以提供NVDIMM。我們使用AgigATech公司的產(chǎn)品對eXtremeDB進行了測試,因為我們非常熟悉AgigA公司的母公司——賽普拉斯半導體。同時我們把測試僅限于AgigA的NVDIMM(比如沒有測試來自VikingTechnology和SmartModularTechnologies公司的NVDIMM),這主要是因為我們的時間和資源非常有限。因此本文中提到的測試只是從概念上證明,內(nèi)存數(shù)據(jù)庫系統(tǒng)可以與NVDIMM一起作為存儲器,達到與使用傳統(tǒng)DRAM相當?shù)男阅?,并且能夠利用NVDIMM的恢復功能恢復由于系統(tǒng)故障“丟失的”內(nèi)存數(shù)據(jù)庫。
測試還解決了在同時要求低延時和數(shù)據(jù)可恢復性的應用中使用內(nèi)存數(shù)據(jù)庫系統(tǒng)時經(jīng)常出現(xiàn)的另外一個問題,即采用事務日志記錄的內(nèi)存數(shù)據(jù)庫系統(tǒng)在多大程度上能保持其性能優(yōu)于基于磁盤的數(shù)據(jù)庫管理系統(tǒng)?對于后面這些涉及永久存儲器(內(nèi)存數(shù)據(jù)庫系統(tǒng)的事務日志存儲,以及在采用磁盤上的數(shù)據(jù)庫管理系統(tǒng)情況下的整個數(shù)據(jù)庫)的測試,存儲“設備”包含了用AGIGARAMNVDIMM配置的RAM盤。下面給出了使用RAM盤而不是傳統(tǒng)硬盤或固態(tài)硬盤的理由。測試中使用的AgigATech公司NVDIMM是設計用于Intel的Romley和Grantley平臺(采用SandyBrdige、IvyBridge、Haswell和Broadwell處理器架構)的。McObject在IntelOakCreekCanyon參考主板中使用了4GBAGIGARAMDDR3-1600NVDIMM,以及Intel奔騰雙核CPU1407@2.8GHz處理器和8GB的金士頓普通DDR3-1333DRAM,運行的是DebianLinux2.6.32.5操作系統(tǒng)。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國內(nèi)實力庫存商家


選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學習編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關系理順;
3、進而練習整數(shù)運算、實數(shù)運算、類型轉換;
4、量程轉換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個物理回路驗證,比如變頻器+電機+測速傳感器);
5、循環(huán)、順序、跳轉等程序控制(盡量避免跳轉,非跳不可時也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學會一種至于其它的學習起來也就簡單了。
