Kune mhando nhatu dzemagetsi dzinoshandiswa pakubatanidza madhisiki ekuchengetera ane 2.5-inch / 3.5-inch: PCIe, SAS neSATA, "Kare, kuvandudzwa kwekubatana kwedata centre kwaitungamirwa neIEEE kana OIF-CEI institutions kana masangano, uye kutaura zvazviri nhasi kwachinja zvakanyanya. Vashandi vedata centre vakuru vakaita seAmazon, Apple, Facebook, Google, neMicrosoft vari kutungamira tekinoroji iyi, kwete kungomirira kuti mitemo ipedzwe, asi kuti mushandisi ataure zvese. Nezve mashandiro emangwana emusika wePCIe SSD, SAS SSD neSATA SSD, taurai nezvekufungidzira kwakaitwa naGartner kuti munhu wese ataure uye ataure.
Nezve PCIe
Hapana mubvunzo kuti PCIe ndiyo inonyanya kufarirwa nemabhazi ekufambisa, uye yakagadziridzwa kakawanda mumakore achangopfuura: PCIe 3.0 ichiri kufarirwa zvakanyanya, PCIe 4.0 iri kukura nekukurumidza, PCIe 5.0 yava kuda kukusangana, PCIe 6.0 specification yapedzwa vhezheni 0.5, uye yakapihwa nhengo dzesangano, ichaburitswa gore rinouya panguva yakatarwa vhezheni yekupedzisira yepamutemo.
Shanduro yega yega yePCIe specification inopfuura nepakati peshanduro/matanho mashanu akasiyana:
Shanduro 0.3: Pfungwa yekutanga inoratidza zvinhu zvakakosha uye magadzirirwo echinhu chitsva ichi.
Shanduro 0.5: Chinyorwa chekutanga chinoratidza zvese zviri muhurongwa hutsva, chinosanganisira mhinduro kubva kunhengo dzesangano zvichibva pashanduro 0.3, uye chinosanganisira zvinhu zvitsva zvinokumbirwa nenhengo pamwe nezvinhu zvitsva.
Shanduro 0.7: Kudhirowa kwakazara, zvese zviri muchimiro chitsva zvakatsanangurwa zvizere, uye chimiro chemagetsi chinofanirawo kusimbiswa ne test chip. Hapana zvinhu zvitsva zvichawedzerwa mushure meizvozvo.
Shanduro 0.9: Chinyorwa chekupedzisira icho nhengo dzesangano dzinogona kugadzira nekugadzira matekinoroji nezvigadzirwa zvavo.
Shanduro 1.0: Kuburitswa kwekupedzisira kwepamutemo, kuburitswa pachena.
Kutaura zvazviri, mushure mekuburitswa kwevhezheni 0.5, vagadziri vanogona kutotanga kugadzira machipisi ekuyedza kuti vagadzirire basa rinotevera pachine nguva.
PCIe 6.0 haina musiyano. Kana ichishanda nePCIe 5.0/4.0/3.0/2.0/1.0, huwandu hwedata kana bandwidth yeI/O huchapetwa kaviri zvakare kusvika pa64GT/s, uye bandwidth chaiyo yePCIe 6.0×1 i8GB/s. PCIe 6.0×16 ine 128GB/s munzira imwe chete uye 256GB/s munzira dzese dziri mbiri.
PCIe 6.0 icharamba ichishandisa 128b/130b encoding yakaunzwa munguva yePCIe 3.0, asi ichiwedzera pulse amplitude modulation itsva PAM4 kuti itsive PCIe 5.0 NRZ, iyo inogona kutakura data rakawanda muchiteshi chimwe chete munguva imwe chete, pamwe ne low latency forward error correction (FEC) uye nzira dzakabatana dzekuvandudza kushanda kwebandwidth.
Nezve SAS
Serial Attached SCSI interface (SAS), SAS ichizvarwa chitsva chetekinoroji yeSCSI, uye hard disk yakakurumbira yeSerial ATA (SATA) yakafanana, inoshandiswa tekinoroji yeserial kuwana kumhanya kwakanyanya kwekutumira, uye nekupfupisa mutsetse wekubatanidza kuti uvandudze nzvimbo yemukati. SAS iinterface itsva yakagadzirwa mushure meiyo parallel SCSI interface. Iyi interface yakagadzirirwa kuvandudza mashandiro, kuwanikwa, uye kugona kwekuchengetedza system, zvichipa kushandirana nema hard drive eSATA. Iyo SAS interface haingotaridzike seSATA chete, asi inoenderana neSATA standard. Backpanel yeSAS system inogona kubatanidza ese ma dual-port, high-performance SAS drives uye ma SATA drives ane simba rakawanda, anodhura zvishoma. Nekuda kweizvozvo, ma SAS drives nema SATA drives anogona kugara pamwe chete mu storage system imwechete. Nekudaro, zvinofanirwa kucherechedzwa kuti ma SATA system haashande neSAS, saka ma SAS drives haagone kubatanidzwa kuma SATA backplanes.
Zvichienzaniswa nekukura kukuru kwePCIe specification mumakore achangopfuura, SAS specification yave ichichinja zvishoma nezvishoma, uye muna Mbudzi 2019, SAS 4.1 specification inoshandisa 24Gbps interface rate yakaburitswa zviri pamutemo, uye chizvarwa chinotevera cheSAS 5.0 specification chiri kugadzirirwawo, izvo zvichawedzera 56Gbps interface rate.
Parizvino, muzvigadzirwa zvitsva zvakawanda, SAS interface SSD SSD ishoma kwazvo, mumwe mukuru wehunyanzvi hwevashandisi veInternet akati vashandisi veInternet havawanzo shandisa SAS SSD, kunyanya nekuda kwezvikonzero zvekushanda kwemutengo, SAS SSD pakati pePCIe neSATA SSD, zvinonyadzisa zvikuru, mashandiro haagone kuenzaniswa nePCIe. Nzvimbo dzedata dzakakura kwazvo dzinosarudza PCIe, mutengo haugone kuwana SATA SSD, vatengi vevatengiwo zvavo vanosarudza SATA SSD.
NezveSATA
SATA iSerial ATA (Serial Advanced Technology Attachment), inozivikanwawo seSerial ATA, inova dhisiki redhisiki rakarongwa pamwe chete neIntel, IBM, Dell, APT, Maxtor, uye Seagate.
SATA interface inoshandisa tambo ina kutumira data, chimiro chayo chiri nyore, Tx+, Tx- inoratidza mutsetse wedata wedhisiki unobuda, unoenderana, Rx+, Rx- inoratidza mutsetse wedhisiki unopinza, semuchina wedhisiki unoshandiswa zvakanyanya pamusika, vhezheni yakakurumbira parizvino i3.0, mukana mukuru weSATA 3.0 interface unofanirwa kunge wakakura, Ordinary 2.5-inch SSD neHDD hard disks dzinoshandisa iyi interface, bandwidth yekutumira ye6Gbps, kunyangwe zvichienzaniswa neinterface itsva ye10Gbps ne32Gbps bandwidth pane musiyano wakati, asi SSD yakajairika ye2.5-inch inogona kusangana nezvinodiwa zvezuva nezuva zvevashandisi vazhinji, 500MB/s kana zvakadaro kumhanya kwekuverenga nekunyora kwakakwana.
