Pali mitundu itatu yolumikizira magetsi ya ma disks osungira 2.5-inch / 3.5-inch: PCIe, SAS ndi SATA, "M'mbuyomu, chitukuko cha kulumikizana pakati pa data chidali choyendetsedwa ndi mabungwe kapena mabungwe a IEEE kapena OIF-CEI, komanso zoona lero zasintha kwambiri.Ogwiritsa ntchito ma data akuluakulu monga Amazon, Apple, Facebook, Google, ndi Microsoft akuyendetsa ukadaulo, osati kudikirira kuti miyezo ikwaniritsidwe, koma kuti wogwiritsa ntchito azilamulira chilichonse.Ponena za tsogolo la msika wa PCIe SSD, SAS SSD ndi SATA SSD, gawani zolosera zomwe Gartner amafotokozera komanso kulumikizana ndi aliyense.
Za PCIe
PCIe mosakayikira ndiyomwe imakonda kwambiri mabasi oyendera, ndipo yasinthidwa pafupipafupi m'zaka zaposachedwa: PCIe 3.0 ikadali yotchuka kwambiri, PCIe 4.0 ikukwera mwachangu, PCIe 5.0 yatsala pang'ono kukumana nanu, mafotokozedwe a PCIe 6.0 amalizidwa 0.5. , ndi kuperekedwa kwa mamembala a bungwe, idzatulutsidwa chaka chamawa pa ndondomeko yomaliza yovomerezeka.
Kusindikiza kulikonse kwa PCIe kumadutsa m'mitundu / magawo asanu:
Mtundu wa 0.3: Lingaliro loyambirira lomwe limapereka zofunikira ndi kapangidwe katsopano katsopano.
Mtundu 0.5: Zolemba zoyambirira zomwe zimazindikiritsa mbali zonse za kamangidwe katsopanoka, zimaphatikizanso ndemanga za mamembala a bungwe kutengera mtundu 0.3, ndikuphatikiza zatsopano zomwe mamembala adapempha kuphatikiza zatsopano.
Mtundu wa 0.7: Kukonzekera kwathunthu, mbali zonse zazomwe zafotokozedwazi zimatsimikiziridwa bwino, ndipo mawonekedwe amagetsi ayeneranso kutsimikiziridwa ndi chipangizo choyesera.Palibe zatsopano zomwe zidzawonjezedwe pambuyo pake.
Mtundu 0.9: Zolemba zomaliza zomwe mamembala a bungwe angapange ndikupanga ukadaulo wawo ndi zinthu zawo.
Mtundu 1.0: Kutulutsidwa komaliza, kutulutsidwa kwa anthu.
M'malo mwake, kutulutsidwa kwa mtundu wa 0.5, opanga atha kuyamba kale kupanga tchipisi toyesa kukonzekera ntchito yotsatira pasadakhale.
PCIe 6.0 ndi chimodzimodzi.Mukabwerera mmbuyo ndi PCIe 5.0/4.0/3.0/2.0/1.0, kuchuluka kwa data kapena I/O bandwidth kudzawirikizanso mpaka 64GT/s, ndipo bandwidth yeniyeni ya PCIe 6.0 × 1 ndi 8GB/s.PCIe 6.0×16 ili ndi 128GB/s mbali imodzi ndi 256GB/s mbali zonse ziwiri.
PCIe 6.0 ipitiliza 128b / 130b encoding yomwe idayambitsidwa mu nthawi ya PCIe 3.0, koma yonjezerani kusintha kwatsopano kwa pulse amplitude PAM4 m'malo mwa PCIe 5.0 NRZ, yomwe imatha kulongedza zambiri munjira imodzi munthawi yofanana, komanso yotsika. latency forward error correction (FEC) ndi njira zowonjezera zowonjezera bandwidth.
Za SAS
Seri Attached SCSI interface (SAS), SAS ndi m'badwo watsopano waukadaulo wa SCSI, ndipo hard disk yotchuka ya seri ATA (SATA) ndi yofanana, ndikugwiritsa ntchito ukadaulo wa seriyo kuti mupeze liwiro lalikulu lotumizira, ndikufupikitsa mzere wolumikizira ku. onjezerani malo amkati.SAS ndi mawonekedwe atsopano opangidwa pambuyo pa mawonekedwe ofanana a SCSI.Mawonekedwewa adapangidwa kuti apititse patsogolo magwiridwe antchito, kupezeka, ndi kusungika kwa makina osungira, kupereka kuyanjana ndi ma hard drive a SATA.Mawonekedwe a SAS samangokhala ofanana ndi SATA, koma ndi kumbuyo amagwirizana ndi muyezo wa SATA.Backpanel ya dongosolo la SAS imatha kulumikiza ma doko apawiri, oyendetsa bwino kwambiri a SAS ndi ma drive apamwamba, otsika mtengo a SATA.Zotsatira zake, ma drive a SAS ndi ma SATA amatha kukhalira limodzi mumayendedwe omwewo.Komabe, ziyenera kudziwidwa kuti machitidwe a SATA sali ogwirizana ndi SAS, chifukwa chake ma drive a SAS sangathe kulumikizidwa ndi ma backplanes a SATA.
Poyerekeza ndi chitukuko chachikulu cha PCIe m'zaka zaposachedwa, mafotokozedwe a SAS asintha pang'onopang'ono, ndipo mu Novembala 2019, mawonekedwe a SAS 4.1 omwe amagwiritsa ntchito 24Gbps adatulutsidwa, ndipo m'badwo wotsatira wa SAS 5.0 ulinso kukonzekera, zomwe zidzawonjezera kuchuluka kwa mawonekedwe ku 56Gbps.
Pakalipano, muzinthu zatsopano zambiri, mawonekedwe a SAS SSD SSD ndi ochepa kwambiri, wotsogolera wogwiritsa ntchito intaneti adanena kuti ogwiritsa ntchito intaneti samagwiritsa ntchito SAS SSD, makamaka chifukwa cha zifukwa zamtengo wapatali, SAS SSD pakati pa PCIe ndi SATA SSD, zochititsa manyazi kwambiri, ntchito zimatha. osafananizidwa ndi PCIe.Malo akuluakulu a data amasankha PCIe, mtengo sungapeze SATA SSD, makasitomala wamba ogula amasankha SATA SSD.
Za SATA
SATA ndi Serial ATA (Serial Advanced Technology Attachment), yomwe imadziwikanso kuti Serial ATA, yomwe ndi mawonekedwe a hard disk mawonekedwe ogwirizana ndi Intel, IBM, Dell, APT, Maxtor, ndi Seagate.
Mawonekedwe a SATA amagwiritsa ntchito zingwe za 4 kuti atumize deta, mawonekedwe ake ndi osavuta, Tx +, Tx- akuwonetsa mzere wosiyana wa deta, wofanana, Rx +, Rx- akuwonetsa mzere wosiyana wa deta, monga mawonekedwe omwe amagwiritsidwa ntchito kwambiri pamsika, mtundu wamakono wotchuka ndi 3.0, mwayi waukulu wa mawonekedwe a SATA 3.0 ayenera kukhala okhwima, Wamba 2.5-inch SSD ndi HDD hard disks amagwiritsa ntchito mawonekedwewa, theoretical transmission bandwidth ya 6Gbps, ngakhale poyerekeza ndi mawonekedwe atsopano a 10Gbps ndi 32Gbps bandwidth kumeneko. ndi kusiyana kwina, koma SSD wamba ya 2.5-inch imatha kukwaniritsa zosowa za tsiku ndi tsiku za ogwiritsa ntchito ambiri, 500MB/s kapena kuwerenga ndi kulemba liwiro ndikokwanira.
