E hele kekahi o nā kumuwaiwai i ka HyperFlex controller VM; ma ke ʻano o ka CPU a me ka hoʻomanaʻo, ua hoʻonohonoho hou wau i ka hoʻonohonoho HyperFlex i ʻole e pāʻani pū me Cisco a hōʻoia i nā kumuwaiwai no nā VM i koe. Akā hiki iā mākou ke haʻalele i nā hoʻololi FibreChannel, a ʻaʻole pono mākou i nā awa Ethernet no kēlā me kēia kikowaena; ua hoʻololi ʻia nā kaʻa kūloko i loko o FI.
ʻO ka hopena ka hoʻonohonoho ʻana no kēlā me kēia kikowaena data:
Nā kikowaena
8 x 1U Server (384 GB RAM, 2 x Intel Gula 6132, FC HBA)
8 x HX240C-M5L (512 GB RAM, 2 x Intel Gula 6150, 3,2 GB SSD, 10 x 6 TB NL-SAS)

ʻAʻole au i hāʻawi i nā laikini polokalamu replication no Hyperflex, no ka mea, loaʻa kēia ma waho o ka pahu no mākou.
No ka hoʻolālā maʻamau, ua koho wau i kahi mea kūʻai aku i hoʻokumu iā ia iho he mea hana kiʻekiʻe a me ke kumu kūʻai. No nā kohoʻelua, ua hoʻohana au i ka ho'ēmi maʻamau no kahi hopena kūikawā, a ma muli o ka hopena ua loaʻa iaʻu nā kumukūʻai maoli.
ʻO ka hopena ʻo Cisco HyperFlex i lilo i 13% ʻoi aku ka liʻiliʻi.
Hōʻike 2: hana ʻana i ʻelua mau kikowaena ʻikepili ikaika. Ma kēia hiʻohiʻona, ke hoʻolālā nei mākou i kahi pūʻulu kikoʻī ma VMware.
ʻO ka papa hana maʻamau he mau kikowaena virtualization, kahi SAN (FC protocol) a me nā ʻōnaehana mālama ʻelua e hiki ke heluhelu a kākau i ka leo i hoʻopaʻa ʻia ma waena o lākou. Ma kēlā me kēia ʻōnaehana hoʻopaʻa ʻana mākou e kau ai i kahi mana kūpono no ka mālama ʻana.
Ma HyperFlex, hana mākou i kahi Stretch Cluster me ka helu like o nā nodes ma nā pūnaewele ʻelua. I kēia hihia, hoʻohana ʻia kahi helu replication o 2+2.
ʻO ka hopena o kēia hoʻonohonoho:

I nā helu āpau, ʻaʻole wau i noʻonoʻo i ka ʻoihana pūnaewele, nā kumukūʻai kikowaena data, a me nā mea ʻē aʻe: e like lākou no ka hoʻolālā maʻamau a no ka hopena HyperFlex.
Ma ke ʻano o ke kumukūʻai, ua lilo ʻo HyperFlex i 5% ʻoi aku ke kumukūʻai. He mea pono e hoʻomaopopo ma ʻaneʻi ma ke ʻano o nā kumuwaiwai CPU / RAM ua loaʻa iaʻu kahi skew no Cisco, no ka mea ma ka hoʻonohonoho hoʻopiha piha ʻana i nā kahawai hoʻomanaʻo hoʻomanaʻo. ʻOi aku ka kiʻekiʻe o ke kumukūʻai, akā ʻaʻole ma ke ʻano o ka nui, e hōʻike maopopo ana ʻaʻole pono ka hyperconvergence he "mea pāʻani no ka poʻe waiwai", akā hiki ke hoʻokūkū me ke ala maʻamau i ke kūkulu ʻana i kahi kikowaena data. He mea hoihoi paha kēia i ka poʻe i loaʻa i nā kikowaena Cisco UCS a me nā ʻōnaehana kūpono no lākou.
Ma waena o nā pōmaikaʻi, loaʻa iā mākou ka nele o nā kumukūʻai no ka lawelawe ʻana i ka SAN a me nā ʻōnaehana mālama, ka hoʻopili pūnaewele a me ka deduplication, kahi helu komo hoʻokahi no ke kākoʻo (virtualization, servers, ʻo ia hoʻi nā ʻōnaehana mālama), mālama i kahi (akā ʻaʻole i nā hiʻohiʻona āpau). hana maʻalahi.
No ke kākoʻo, eia ʻoe e kiʻi mai kahi mea kūʻai aku - Cisco. Ke hoʻoholo nei i koʻu ʻike me nā kikowaena Cisco UCS, makemake wau ia; ʻAʻole pono wau e wehe iā ia ma HyperFlex, hana like nā mea āpau. E pane koke nā ʻenekinia a hiki ke hoʻoponopono i nā pilikia maʻamau, akā i nā hihia lihi paʻakikī. I kekahi manawa, huli au iā lākou me nā nīnau: "Hiki paha ke hana i kēia, hoʻopaʻa ʻia?" a i ʻole "Ua hoʻonohonoho wau i kekahi mea ma aneʻi, ʻaʻole makemake e hana. Kōkua!" - e hoʻomanawanui lākou i ke alakaʻi e pono ai ma laila a kuhikuhi i nā hana kūpono; ʻaʻole lākou e pane: "Hoʻoponopono wale mākou i nā pilikia hardware."
