Kuwanikwa kwepamusoro (HA) masisitimuzvakakosha kuve nechokwadi chekuenderera mberi kwekushanda kweakakosha maapplication nemasevhisi. Aya masisitimu akagadzirirwa kuderedza nguva yekudzikira uye kuve nechokwadi chekuita pasina musono, achiaita chikamu chakakosha chemazuva ano IT zvivakwa. Mune ino blog, isu tichaongorora mune tekinoroji maitiro eHA masisitimu uye toongorora kuti anovandudza sei kuvimbika uye kusimba.
1. Redundancy: Chimwe chezvinhu zvakakosha zvehunyanzvi zveHA system ndeyedundancy. Izvi zvinosanganisira kudzokorora zvinhu zvakakosha semasevha, kuchengetedza uye network zvishandiso kuti ive nechokwadi chekuti kana chimwe chikamu chikatadza, pane backup yakagadzirira kutora. Redundancy yakakosha kudzikisa mapoinzi ega ekutadza uye kuve nechokwadi chekuenderera mberi nekushanda muchiitiko chehardware kana software nyaya.
2. Failover mechanism: HA masisitimu akashongedzerwa nefoilover mechanism iyo inogona kushandura otomatiki kune backup zvikamu kana masisitimu muchiitiko chekutadza. Izvi zvinogona kusanganisira otomatiki rerouting yetiweki traffic, kushandura kune mamwe maseva kana kukundikana kune backup yekuchengetedza zvishandiso. Failover maitiro akagadzirirwa kuderedza kukanganiswa kwesevhisi uye kuve nechokwadi chekuenderera mberi kwekushanda.
3. Kuenzanisa Kwemutoro: HA masisitimu anowanzo shandisa nzira dzekuenzanisa mitoro kugovera mutoro webasa pamaseva akawanda kana zviwanikwa. Izvi zvinobatsira kukwidziridza mashandisirwo ezviwanikwa uye kudzivirira chero chinhu chimwe chete kubva pakuremerwa. Nekugovera zvakaenzana mitoro yebasa, HA masisitimu anogona kuchengetedza kuita uye kuwanikwa kunyangwe panguva dzekushandiswa kwepamusoro.
4. Kuongorora uye Kuchenjerera: Kunyatsotarisa uye kuchenjerera zvigadziro zvakakosha kune HA masisitimu. Aya masisitimu anoramba achitarisisa hutano nekuita kwezvikamu zvakakosha uye masevhisi, achizivisa vatariri nezve chero zvingangoitika nyaya kana anomalies. Proactive monitoring inoona matambudziko nekukurumidza, ichibvumira kupindira panguva yekudzivirira kuderera kana kuderedzwa kwebasa.
5. Kudzokororwa kwedata: Kudzokororwa kwedata chinhu chakakosha cheHA masisitimu, kuve nechokwadi chekuti data yakakosha inodzokororwa pamidziyo yakawanda yekuchengetedza kana nzvimbo. Izvi hazvingopi chete kuchengetedzwa kwedata muchiitiko chekutadza kwehardware, asi zvakare inogonesa seamless failover kune redundant kuchengetedza masisitimu pasina kurasikirwa kwedata.
6. Automated recovery: HA masisitimu akagadzirirwa otomatiki maitiro ekudzoreredza muchiitiko chekutadza. Izvi zvinogona kusanganisira otomatiki failover, kudzoreredza sevhisi, uye kubatanidzwazve kwezvakakundikana zvikamu mushure mekunge dambudziko ragadziriswa. Otomatiki kudzoreredza maitiro anobatsira kuderedza kukanganisa kwekutadza uye kuderedza kudiwa kwekupindira kwemanyorero.
7. Scalability: Scalability chimwe chinhu chakakosha chehunyanzvi hweHA system. Aya masisitimu akagadzirwa kuti akwire zvisina musono kuti aenderane nekukura kwemabasa uye zviwanikwa zvinodiwa. Kunyangwe kuwedzera mamwe maseva, kuchengetedza, kana network network, HA masisitimu anogona kuenderana nekuchinja zvinodiwa pasina kukanganisa kuwanikwa.
Muchidimbu, hunyanzvimaitiro eHA masisitimukuita basa rakakosha mukuona kuvimbika, kusimba, uye kuenderera mberi kwekushanda kweakakosha maapplication nemasevhisi. Nekubatanidza redundancy, failover masisitimu, kuyera kuyera, kutarisa, kudzokorodza data, kudzoreredza otomatiki, uye scalability, HA masisitimu anounza kuwanikwa kwakanyanya uye kuita, zvichiita kuti zvive zvakakosha munzvimbo yanhasi yedhijitari. Kunzwisisa aya maitiro ehunyanzvi kwakakosha kumasangano ari kutsvaga kuita yakasimba HA mhinduro kutsigira mashandiro avo akakosha ebhizinesi.
