Momwe mungagwiritsire ntchito SAP HANA: timasanthula njira zosiyanasiyana

SAP HANA ndi DBMS yodziwika bwino mu-memory yomwe imaphatikizapo ntchito zosungiramo zinthu (Data Warehouse) ndi analytics, zomangidwa mkati, seva yogwiritsira ntchito, ndi nsanja yokonzekera kapena kupanga zatsopano zothandizira. Pochotsa kuchedwa kwa ma DBMS achikhalidwe ndi SAP HANA, mutha kukulitsa kwambiri magwiridwe antchito, ma transaction process (OLTP) ndi nzeru zamabizinesi (OLAP).

Mutha kutumiza SAP HANA mumayendedwe a Appliance ndi TDI (ngati tilankhula za malo opangira). Pachisankho chilichonse, wopanga ali ndi zofunikira zake. Mu positi iyi tidzakambirana za ubwino ndi zovuta za zosankha zosiyanasiyana, komanso, momveka bwino, za ntchito zathu zenizeni ndi SAP HANA.

SAP HANA ili ndi zigawo zitatu zazikuluzikulu - host, chitsanzo ndi dongosolo.

Wolandira ndi seva kapena malo ogwiritsira ntchito poyendetsa SAP HANA DBMS. Zomwe zimafunikira ndi CPU, RAM, yosungirako, network ndi OS. Wolandirayo amapereka maulalo kumayendedwe oyika, ma data, zipika, kapena mwachindunji kumalo osungira. Panthawi imodzimodziyo, njira yosungiramo yosungirako SAP HANA sikuyenera kukhala pa wolandira. Ngati makinawa ali ndi makamu angapo, mudzafunika kusungirako komwe kugawidwa kapena komwe kulipo pofunidwa kuchokera kwa onse omwe ali nawo.

Chitsanzo - seti ya SAP HANA zida zadongosolo zomwe zimayikidwa pagulu limodzi. Zigawo zazikuluzikulu ndi Index Server ndi Name Server. Yoyamba, yomwe imatchedwanso "seva yogwira ntchito," imayendetsa zopempha, imayang'anira masitolo amakono ndi ma injini a database. Name Server imasunga zambiri za topology ya kukhazikitsa SAP HANA - komwe zigawo zimayenda ndi zomwe zili pa seva.

dongosolo - ichi ndi chimodzi kapena zingapo zomwe zili ndi nambala yomweyo. Kwenikweni, ichi ndi chinthu china chomwe chitha kuyatsidwa, kuzimitsa kapena kukopera (zosungidwa). Deta imagawidwa mu kukumbukira ma seva osiyanasiyana omwe amapanga dongosolo la SAP HANA.

Dongosololi litha kukhazikitsidwa ngati gulu limodzi (mwachitsanzo pagulu limodzi) kapena gulu lambiri, logawidwa (zochitika zingapo za SAP HANA zimagawidwa pamagulu angapo, ndi chitsanzo chimodzi pa wolandira). M'machitidwe ochitira anthu ambiri, chochitika chilichonse chiyenera kukhala ndi nambala yofanana. Dongosolo la SAP HANA limadziwika ndi ID ya System (SID), nambala yapadera yokhala ndi zilembo zitatu za alphanumeric.

SAP HANA Virtualization

Chimodzi mwazolepheretsa chachikulu cha SAP HANA ndi chithandizo cha dongosolo limodzi lokha - chitsanzo chimodzi chokhala ndi seva yapadera ya SID. Kuti mugwiritse ntchito hardware bwino kwambiri kapena kuchepetsa chiwerengero cha ma seva mu data center, mungagwiritse ntchito virtualization. Mwanjira iyi, malo ena akhoza kukhala pa seva yomweyo ndi machitidwe omwe ali ndi zofunikira zochepa (machitidwe osabereka). Kwa seva yoyimilira ya HA / DR, kuwonetsetsa kungathe kupititsa patsogolo liwiro la kusintha pakati pa makina opanga komanso osapanga.

SAP HANA imaphatikizapo chithandizo cha VMWare ESX hypervisor. Izi zikutanthauza kuti machitidwe osiyanasiyana a SAP HANA - makhazikitsidwe a SAP HANA okhala ndi manambala osiyanasiyana a SID - amatha kukhala pagulu limodzi (seva wamba wakuthupi) mumakina osiyanasiyana. Makina aliwonse amtundu uliwonse ayenera kuthamanga pa OS yothandizidwa.

Pamalo opangira, SAP HANA virtualization ili ndi malire akulu:

• Kukulitsa sikelo sikumathandizidwa - kuwonetsetsa kungagwiritsidwe ntchito ndi machitidwe a Scale-Up, kaya BwoH/DM/SoH kapena “pure” SoH;
• virtualization iyenera kuchitidwa mkati mwa malamulo okhazikitsidwa pazida za Appliance kapena TDI;
• General Availability (GA) ikhoza kukhala ndi makina amodzi okha - makampani omwe akufuna kugwiritsa ntchito mawonekedwe opangidwa ndi HANA akuyenera kutenga nawo gawo mu pulogalamu ya Controlled Availability ndi SAP.

M'malo osapanga zinthu pomwe zoletsa izi kulibe, virtualization ingagwiritsidwe ntchito kukhathamiritsa kugwiritsa ntchito ma hardware.

SAP HANA topology

Tiyeni tipitirire kuyika SAP HANA. Ma topology awiri akufotokozedwa apa.

• Kukulitsa - seva imodzi yayikulu. Pamene maziko a HANA akukula, seva yokhayo imakula: chiwerengero cha CPUs ndi kuchuluka kwa kukumbukira kukumbukira. Mumayankho okhala ndi Kupezeka Kwapamwamba (HA) ndi Kubwezeretsa Masoka (DR), zosunga zobwezeretsera kapena zololera zolakwika ziyenera kufanana ndi mawonekedwe a maseva opanga.
• Scale-out - voliyumu yonse ya SAP HANA system imagawidwa pa ma seva angapo ofanana. Master Server ili ndi chidziwitso cha Index Server ndi Name Server. Ma seva akapolo alibe deta iyi - kupatula seva, yomwe imatenga ntchito za Mbuye pakagwa kulephera kwa seva yaikulu. Ma seva a Index amayang'anira magawo a data omwe amaperekedwa kwa iwo ndikuyankhanso mafunso. Name Server amadziwa momwe deta imagawidwira pakati pa ma seva opanga. Ngati HANA ikukula, node ina imangowonjezeredwa ku kasinthidwe ka seva komweko. Mu topology iyi, ndikwanira kukhala ndi node imodzi yosungira kuti mutsimikizire chitetezo cha seva yonse.

Zofunikira za SAP hardware

SAP ili ndi zofunikira za hardware zovomerezeka za HANA. Amakhudzana ndi malo opangira - kwa osapanga, mawonekedwe ochepa ndi okwanira. Kotero, apa pali zofunikira za malo opanga:
