Izinto zikagesi ze-ExaGrid zingakwazi ukugcina kalula izipele ezingaphandle kwendawo ngokusebenzisa umshini we-ExaGrid ongekho endaweni ngokuhlangana nomshini wokuqala we-ExaGrid wesayithi. Ukwenza ikhophi yasenqolobaneni yedatha yakho kumshini we-ExaGrid esizeni sakho esiyinhloko kunciphisa ngokuphawulekayo inani lesikhala sediski esidingekayo ukuze kugcinwe yonke leyo datha ngenxa yekhono layo eliphezulu lokudonswa kwedatha. Endaweni ye-ExaGrid yamasayithi amaningi, isistimu ye-ExaGrid eku-site ithumela kuphela idatha ekopishiwe—idatha eyisipele eshintshayo ngezinga lembudumbudu phakathi kwekhophi ngayinye eyisipele—ngenethiwekhi yendawo ebanzi (WAN) iye kolunye uhlelo lukagesi lwe-ExaGrid. Umshini osebenza ngaphandle kwe-ExaGrid ulungele ukubuyiselwa kwedatha kanye nokululama ngokushesha uma kwenzeka kuba nenhlekelele noma okunye ukuphela kwesizinda.

Uma ukuphindaphinda kuyindlela eyodwa kuphela, isayithi lesibili i-ExaGrid ingaba uhhafu womthamo wesayithi eliyinhloko i-ExaGrid, kwehlise kakhulu izindleko zizonke.

Ukuphindaphinda phakathi kwamasistimu e-ExaGrid kuyo yonke i-WAN kungahlelelwa usuku lweviki kanye nezikhathi eziningi phakathi nosuku ngalunye. Isikhathi ngasinye esihleliwe sivumela ukunyakaziswa komkhawulokudonsa okhawulela ukuphindaphinda ukusebenzisa kuphela umkhawulokudonsa owabelwe. Inhlanganisela yokuguquguquka kokuhlela kanye nokudonsa komkhawulokudonsa kuvumela ukusebenza kahle okuphezulu komkhawulokudonsa we-WAN osetshenziselwa ukuphindaphinda. Idatha eyimpinda ingabethelwa nge-WAN kusetshenziswa i-VPN yekhasimende noma ngokusebenzisa ukubethela kwe-Replication eyakhelwe ngaphakathi kwe-ExaGrid.
I-ExaGrid isekela izinketho ezihlukahlukene ze-DR:

I-Cloud Private

• Ukuphindaphinda ku-ExaGrid esikhungweni sedatha sesibili sekhasimende (isayithi le-DR)
• Ukuphindaphinda ku-ExaGrid esikhungweni sedatha esingethwe yinkampani yangaphandle (isayithi le-DR)

I-Cloud Hybrid

• Ukulingisa Umhlinzeki Wesevisi Ophethwe (MSP)

Ifu Lomphakathi

• Ukuphindaphinda ku-ExaGrid VM efwini lomphakathi (Amazon AWS, Microsoft Azure), lapho
• Idatha ye-DR igcinwa efwini lomphakathi futhi ikhokhiswe yi-GB ngenyanga kusetshenziswa isabelomali se-OPEX

I-ExaGrid isekela amamodeli amathathu wamasayithi e-DR amafu ayimfihlo esikhungweni sedatha esingaphandle kwesizinda sekhasimende:

• Ukuphindaphinda okukodwa kokunye ukuze kulungiswe kabusha inhlekelele - Kulokhu ukusetshenziswa, konke
  isistimu engaphandle kwendawo ingalungiselelwa indawo yokugcina, okuvumela ukuthi kusetshenziswe isistimu yosayizi oyingxenye
  ngaphandle kwendawo. I-ExaGrid i-asymmetrical kuleli cala lokusetshenziswa lapho zonke ezinye izixazululo zilingana.
• Ukuvikelwa kwesiphambano - Idatha ingenziwa ikhophi yasenqolobaneni kokubili kumasistimu angaphandle nakwe-onsite kanye nesiphambano
  iphindaphindwe ngendlela yokuthi indawo ngayinye ibe yindawo yokulungisa inhlekelele kwenye.
• I-Multi-hop - I-ExaGrid ivumela ikhophi yemfundo ephakeme enezihloko ezimbili ezihlukene.
  - Isayithi A lingakwazi ukuphindaphinda kusayithi B bese indawo B ingakwazi ukuphindaphinda kusayithi C
  - Isayithi A lingakwazi ukuphindaphinda kusayithi B futhi indawo A nayo ingaphindaphinda kusayithi C
  - ISayithi C ingaba isiza esingokoqobo noma umhlinzeki wamafu njenge-Amazon AWS & Azure
• Amasayithi amaningi esikhungo sedatha - I-ExaGrid ingakwazi ukusekela amasayithi angafika kwangu-16 endaweni eyodwa futhi akhulume
  i-topology enezikhulumi eziyi-15 kuhabhu. Amasistimu agcwele noma amasheya angawodwana angaphindaphindwa
  ukuze amasayithi esikhungo sedatha asebenze njengendawo yokutakula inhlekelele enye kwenye.
