Pali mitundu itatu yolumikizira magetsi ya ma disks osungira 2.5-inch / 3.5-inchi: PCIe, SAS ndi SATA, "M'mbuyomu, kukulitsa kulumikizana kwa data Center kudayendetsedwa ndi mabungwe kapena mabungwe a IEEE kapena OIF-CEI, ndipo lero asintha kwambiri. lamulani chilichonse Pantchito yamtsogolo ya msika wa PCIe SSD, SAS SSD ndi SATA SSD, gawani zolosera zomwe Gartner angatchule komanso kulumikizana ndi aliyense.
Za PCIe
PCIe mosakayikira ndiye mulingo wodziwika kwambiri wamabasi, ndipo wasinthidwa 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 mtundu 0.5, ndikuperekedwa kwa mamembala a bungwe chaka chamawa, ndandanda yomaliza idzatulutsidwa.
Kusindikiza kulikonse kwa PCIe kumadutsa m'mitundu / magawo asanu:
Mtundu wa 0.3: Lingaliro loyambirira lomwe limapereka mawonekedwe ofunikira 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 kudzawirikiza kawiri 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 idzapitiriza 128b / 130b encoding yomwe inayambika mu nthawi ya PCIe 3.0, koma yonjezerani kusintha kwatsopano kwa pulse amplitude PAM4 m'malo mwa PCIe 5.0 NRZ, yomwe imatha kulongedza deta yambiri mu njira imodzi mu nthawi yofanana, komanso kutsika kwa latency patsogolo kuwongolera kolakwika (FEC)
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 kuti muwongolere 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 awiri, 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, kotero 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 pogwiritsa ntchito mawonekedwe a 24Gbps adatulutsidwa movomerezeka, ndipo m'badwo wotsatira wa SAS 5.0 ulinso pakukonzekera, zomwe ziwonjezera kuchuluka kwa mawonekedwe mpaka 56Gbps.
Pakalipano, muzinthu zambiri zatsopano, 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 sizingafanane 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.
SATA mawonekedwe ntchito zingwe 4 kufalitsa deta, dongosolo lake ndi losavuta, Tx +, Tx- limasonyeza linanena bungwe kusiyana deta mzere, lolingana, Rx +, Rx- limasonyeza athandizira masiyanidwe mzere deta, monga ambiri ntchito kwambiri litayamba mawonekedwe mu msika, panopa wotchuka Baibulo ndi 3.0, mwayi waukulu wa SATA 3.0 mawonekedwe ayenera kukhala okhwima, 5-inch hard disk mawonekedwe SSD2re HD. kutumiza bandwidth ya 6Gbps, ngakhale poyerekeza ndi mawonekedwe atsopano a 10Gbps ndi 32Gbps bandwidth pali kusiyana kwina, koma wamba 2.5-inch SSD ikhoza kukwaniritsa zosowa za tsiku ndi tsiku za ogwiritsa ntchito ambiri, 500MB / s kapena kuwerenga ndi kulemba liwiro ndikwanira.
