PCIe vs SAS vs SATA: Hondo yeInotevera-Generation Storage Interface Technologies
Parizvino, iyo 2.5-inch/3.5-inch yekuchengetera hard disks muindastiri inonyanya kuve nematanho matatu: PCIe, SAS uye SATA. Mu data center applications, mhinduro dzekubatanidza dzakadai seMINI SAS 8087 kusvika 4X SATA 7P Murume tambo uye MINI SAS 8087 kune SLIM SAS 8654 4I inoshandiswa zvakanyanya. Munguva yakapfuura, kuvandudzwa kwedata center interconnection upgrades yainyatsotungamirirwa nemasangano kana masangano akaita seIEEE kana OIF-CEI. Zvisinei, kuchinja kukuru kwakaitika mazuva ano. Mahombe data centre vanoshanda seAmazon, Apple, Facebook, Google neMicrosoft vava kutyaira tekinoroji.
About PCIe
PCIe pasina mubvunzo ndiyo inonyanya kufarirwa bhazi chiyero, uye zvigadziriso zvayo zvave zvichiwanzoitika mumakore achangopfuura. Kunyangwe iyo yekumhanyisa yekusimudzira yakawedzera, shanduko muchizvarwa chega chega chePCIe yakatarwa yakakosha, kunyanya nebandwidth inopetwa kaviri nguva imwe neimwe uye kuchengetedza kuenderana nezvizvarwa zvese zvakapfuura.
PCIe 6.0 haina mutsauko. Ndichiri kumashure kunoenderana nePCIe 5.0/4.0/3.0/2.0/1.0, iyo data rate kana I/O bandwidth ichapeta zvakare kusvika ku64 GT/s. Iyo chaiyo-imwe nzira bandwidth yePCIe 6.0 x1 ndeye 8 GB/s, iyo-imwe nzira bandwidth yePCIe 6.0 x16 ndeye 128 GB/s, uye bidirectional bandwidth i256 GB/s. Iyi yepamusoro-speed interface yakapawo mhinduro itsva dzekubatanidza seMCIO 8I kusvika 2 OCuLink 4i tambo, PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i kusvika 4 SATA 7-Pin Right-Angled Cable, nezvimwe.
Pamusoro peSAS
Iyo Serial Yakanamatira SCSI interface (Serial Yakanamatira SCSI, SAS) ndiyo inotevera-chizvarwa SCSI tekinoroji. Kungofanana neazvino anozivikanwa Serial ATA (SATA) madhiraivha akaomarara, SAS zvakare inotora serial tekinoroji kuti iwane yakakwira yekumhanyisa kumhanya uye inovandudza nzvimbo yemukati nekupfupisa mitsetse yekubatanidza. SAS iratidziro nyowani yakagadziridzwa mushure meiyo yakafanana SCSI interface. Mumazuva ano ekuchengetedza masisitimu, tambo dzekubatanidza seMINI SAS 8087 kusvika 8482 CABLE, MINI SAS 8087 kusvika 4X SATA 7P tambo yechikadzi, nezvimwewo, inoita basa rakakosha. Kunyanya iyo yekurudyi-ekona yekubatanidza chirongwa cheMINI SAS 8087 kusvika 4X SATA 7P kurudyi kona yevakadzi tambo inonyanya kufarirwa munzvimbo dzeseva dzine nzvimbo shoma.
Pamusoro peSATA
SATA inomirira seri ATA (Serial Advanced Technology Attachment), inozivikanwawo seserial ATA. Iyo yakaoma dhiraivha interface yakatarwa yakabatana yakakurudzirwa neIntel, IBM, Dell, APT, Maxtor uye Seagate.
Sezvo inonyanya kushandiswa hard disk interface mumusika wezvino, mukana mukuru weSATA 3.0 interface inofanira kunge iri kukura kwayo. Ose ari maviri akajairwa 2.5-inch SSD uye HDDs anoshandisa iyi interface. Panyaya yemhinduro dzekubatanidza, iyo MINI SAS 8087 kusvika 4X SATA 7P Mukadzi ane Sideload inopa yakareruka yekupinza mhinduro, nepo MINI SAS 8087 kusvika 4X SATA 7P yekurudyi-kona yechikadzi tambo inokodzera mamiriro ane nzvimbo shoma. Iyo theoretical transmission bandwidth ndeye 6 Gbps. Kunyangwe iine imwe gap kana ichienzaniswa negumi Gbps uye 32 Gbps bandwidth yeiyo nyowani interface, yakajairwa 2.5-inch SSDs inogona kusangana nezvinodiwa zvezuva nezuva zvevashandisi vazhinji, uye kumhanya kwekuverenga nekunyora kunosvika mazana mashanu MB/s kwakakwana.
Huwandu hwe data munyika yeInternet huri kuwedzera nekukurumidza. Kuenzaniswa neazvino interfaces, iyo PCI Express interface inogona kupa nekukurumidza kutapurirana data uye kupfupika latency, zvakanyanya kuvandudza mashandiro uye pundutso yemasangano. Zvakanakira zvichawedzera kuoneka. Panguva imwecheteyo, zvigadziriso zvekubatanidza zvakaita seMINI SAS 8087 kuenda kuSAS SFF-8482 Two-in-One tambo uye MINI SAS 8087 kuenda kuOculink SAS 8611 4I zvakare iri kusunda miganhu yetekinoroji yekuchengetedza. Kunyanya munzvimbo dzekuchengetera dzakakwirira-density, iyo yakakosha-angle yekubatanidza madhizaini senge MINI SAS 8087 Kuruboshwe-angled ku4X SATA 7P Mukadzi 90-Degree akagadzirisa matambudziko ewaya.
