Mu ecosystem ye Windows Server, Nzvimbo dzekuchengetera ndiyo software-yakatsanangurwa yekuchengetedza layer iyo inokutendera kuti uunganidze madhisiki emuviri (SATA, SAS, SSD, NVMe…) mu "dziva" kana boka rekuchengetedza, iro madhisiki chaiwo anozogadzirwa aine mazinga akasiyana ekusimba (nyore, girazi, parity).
Pfungwa ye kuchengetedza tiering kana mazinga Izvi zvinopinda mukutamba kana isu tichibatanidza madhiraivha eakasiyana mazinga ekuita mukati medziva iroro: semuenzaniso, maSSD kana NVMe ekukurumidza tier uye echinyakare HDDs yesimba tier. Nzvimbo dzekuchengetera dzinogona kufambisa "inopisa" (inowanzo kuwanikwa) data kune iyo inokurumidza tier uye kusiya "inotonhora" data mune inononoka, yakachipa tier.
Muchiitiko chinowanzoitika, Iwe waizove nekuita tier yakavakirwa paSSD/NVMe uye chiyero chesimba chakavakirwa paHDDWindows yemukati inogadzirisa kuiswa kwevhavha uye kutama pakati petier, zvakafanana nezvinoitwa neSAN array mhinduro, asi uchishandisa akajairwa x86 maseva ane madhisiki emunharaunda.
Iyi yakafanana tiered maitiro inoonekwa zvakare mune vamwe vagadziri uye makore eruzhinji, kwavanopa makirasi ekuchengetedza nemitengo yakasiyana uye nguva dzekuwanaShanduko inoitwa otomatiki zvichienderana nemaitiro ekushandisa.

Storage Spaces Direct (S2D): hwaro hwe hyperconvergence muWindows
Storage Spaces Direct, kana S2D kwenguva pfupi, ndiko kushanduka kwechinyakare Nzvimbo dzekuchengeta iyo yakatanga kuonekwa muWindows Server 2012 R2. Iine S2D, Microsoft inotora pfungwa yesoftware-yakatsanangurwa chengetedzo kusvika yakanyanyisa: pachinzvimbo chekuvimba nekunze kweSAN array, maseva emapoka pachawo anopa madhisiki emunharaunda, ayo akaunganidzwa kuita dziva rimwe rakagoverwa.
Iyi tekinoroji chikamu chepakati che Azure Stack HCI uye iyo Datacenter editions yeWindows Server (2016, 2019, 2022 uye gare gare, kusanganisira Azure Edition). Iko hakuna chikonzero chekuisa chero chinhu chisina kujairika zvikamu: iyo yakabatanidzwa mune inoshanda sisitimu uye inogoneswa pamusoro peiyo yechinyakare failover cluster.
NeS2D unogona kuvaka mhando mbiri dzekutumira: iyo yemhando yepamusoro hyperconverged mamiriro, umo iwo manodhi akafanana anopa komputa (Hyper-V chaiwo muchina) uye chengetedzo, uye iyo yakachinjika kana yakapatsanurwa mamiriro, ine rimwe sumbu rakatsaurirwa chete kuchengetedza uye imwe kune komputa inowanikwa kuburikidza neSOFS (Scale-Out File Server).
Munzvimbo dzine zvibereko, Microsoft inokurudzira kushandisa hardware yakagadziriswa yeS2D kana Azure Stack HCI mapuratifomuIine angangoita matatu node kana iwe uchida kukwanisa kurasikirwa neimwe isina kukanganiswa sevhisi, uye madhisiki akakodzera (SAS, SSD, NVMe…) mune yega yega server. Nekushandisa lab, unogona kubata nezvakaderera, kunyangwe neSATA uye nezvimwe "zvekugadzira" zvigadziriso, asi iyo inyaya yakasiyana uye isingatsigirwe mukugadzira.
Zvikamu zvakakosha zveKuchengeta Nzvimbo Yakananga uye tiering
Kuti unzwisise kuti Nzvimbo dzekuchengeta, S2D, uye tiering zvakasanganiswa sei, zvinobatsira kuongorora iyo tekinoroji zvikamu zviri pasi peiyo graphical interface kana yevakapinda.
Chekutanga pane zvese, isu tinoda hardware inowirirana uye nhamba yakakwana yemadhisikiCertified x86 maseva, imwe neimwe ine akawanda emunharaunda madhiraivha anogona kusanganisa NVMe, SSD, uye HDD. Musanganiswa uyu unotibvumira kugadzira matinji akasiyana mukati medziva rimwe chete, semuenzaniso, inokurumidza-yese-flash tier uye inokwana tier ine mechaniki disks.
Iyo network ndiyo imwe mbiru yakakosha, nekuti iyo software-yakatsanangurwa kuchengetedza bhazi Izvi zvinoita kuti node dzese dziri muchikwata dzione madhisiki emunharaunda emumwe nemumwe sekunge ari mune chassis yakafanana. Kuti izvi zvishande zvakanaka, zvinokurudzirwa zvikuru kushandisa masisitimu ekukurumidza ane RDMA (RoCE kana iWARP) pa10 GbE kana pamusoro, kunyanya mumasumbu ekugadzira ane IOPS yakakwira.
Pamusoro pebhazi iroro, dziva rimwe chete rekuchengetedza rakavakwa izvo zvinounganidza zvese zviripo. Kubva padziva iri, madhisiki edhisiki kana Nzvimbo dzeKuchengeta anogadzirwa, umo rudzi rwekusimba (rakapfava, girazi, parity) uye mutemo wetiering zvinogadziriswa, zvichiratidza kuti ndechipi chikamu chinotsigirwa neSSD/NVMe uye chikamu chipi neHDD.
Nezve madhisiki chaiwo iwayo, chinhu chakajairika kushandisa ndechekuti ReFS (Resilient File System) seyakakurudzirwa faira systemReFS inonyanya kubatsira kune virtualization basa rekutakura neHyper-V kana VHDX kuchengetedza.
