Banyere PCIe
Ihe ịrụ ụka adịghị ya na PCIe bụ ọkọlọtọ ụgbọ ala ụgbọ njem kachasị ewu ewu, yana emelitere ya ugboro ugboro n'afọ ndị na-adịbeghị anya: PCIe 3.0 ka bụ nke kachasị ewu ewu, PCIe 4.0 na-ebili ngwa ngwa, PCIe 5.0 na-aga izute gị, nkọwapụta PCIe 6.0 agwụla ụdị 0.5, ma nye ndị otu nzukọ ahụ, a ga-ahapụ ya n'afọ na-abịa na ụdị gọọmentị ikpeazụ.
Mpempe akwụkwọ nkọwapụta PCIe ọ bụla na-aga ụdị / ọkwa ise dị iche iche:
Ụdị 0.3: Echiche mbido nke na-egosi njirimara ndị bụ isi na nhazi nke nkọwapụta ọhụrụ.
Ụdị 0.5: Nkọwapụta mbụ nke na-akọwapụta akụkụ niile nke ụlọ ọhụrụ ahụ, na-agụnye nzaghachi sitere n'aka ndị otu nzukọ dabere na ụdị 0.3, ma tinye atụmatụ ọhụrụ nke ndị otu rịọrọ gbakwunyere atụmatụ ọhụrụ.

N'ezie, mgbe mwepụta nke ụdị 0.5, ndị na-emepụta nwere ike ịmalite ịmepụta ibe ule iji kwadebe maka ọrụ na-esote n'ọdịnihu.
PCIe 6.0 abụghị ihe ọzọ. Mgbe azụ azụ dakọtara na PCIe 5.0/4.0/3.0/2.0/1.0, data ọnụego ma ọ bụ I/O bandwit ga- okpukpu abụọ ọzọ 64GT/s, na n'ezie unidirectional bandwit nke PCIe 6.0 × 1 bụ 8GB/s. PCIe 6.0 × 16 nwere 128GB/s n'otu ụzọ yana 256GB/s n'akụkụ abụọ ahụ.
PCIe 6.0 ga-aga n'ihu na ntinye koodu 128b / 130b ewebata na oge PCIe 3.0, mana gbakwunye PAM4 pulse amplitude modulation ọhụrụ iji dochie PCIe 5.0 NRZ, nke nwere ike itinyekwu data n'otu ọwa n'otu oge ahụ, yana obere latency n'ihu mmezi njehie (FEC).
Banyere SAS
Serial Attached SCSI interface (SAS), SAS bụ ọgbọ ọhụrụ nke teknụzụ SCSI, na diski ike Serial ATA (SATA) na-ewu ewu bụ otu, bụ ojiji nke teknụzụ serial iji nweta ọsọ ọsọ dị elu, yana site n'imebi akara njikọ iji meziwanye oghere dị n'ime. SAS bụ interface ọhụrụ emepụtara ka SCSI yiri ya. Emebere interface a iji melite arụmọrụ, ịdị adị, na scalability nke sistemụ nchekwa, na-enye ndakọrịta na draịvụ ike SATA. Ihe interface SAS abụghị naanị na ọ dị ka SATA, mana ọ dabara na ọkọlọtọ SATA azụ azụ. Backpanel nke sistemu SAS nwere ike jikọọ ma ọdụ ụgbọ mmiri abụọ, draịva SAS dị elu na ikike dị elu, draịva SATA dị ọnụ ala. N'ihi ya, SAS draịva na SATA draịva nwere ike ibikọ ọnụ n'otu usoro nchekwa. Agbanyeghị, ekwesịrị ịmara na sistemụ SATA anaghị dakọtara na SAS, yabụ enweghị ike ijikọ draịva SAS na ụgbọ elu SATA.
Tụnyere nnukwu mmụba n'ihu mmepe nke nkọwapụta PCIe n'afọ ndị na-adịbeghị anya, nkọwapụta SAS ji nwayọọ nwayọọ malite nwayọ, yana na Nọvemba 2019, a tọhapụrụ nkọwapụta SAS 4.1 site na iji ọnụego interface 24Gbps, na nkọwapụta SAS 5.0 na-esote na-adịkwa njikere, nke ga-abawanye ọnụego interface na 56Gbps.
Ka ọ dị ugbu a, na ọtụtụ ọhụrụ ngwaahịa, SAS interface SSD SSD dị ole na ole, onye Internet ọrụ teknuzu director kwuru na Internet ọrụ adịkarịghị eji SAS SSD, tumadi n'ihi na-eri arụmọrụ ihe, SAS SSD n'etiti PCIe na SATA SSD, nnọọ ihere, arụmọrụ enweghị ike tụnyere PCIe. Ultra-nnukwu data center na-ahọrọ PCIe, ọnụahịa enweghị ike ịnweta SATA SSD, ndị ahịa ahịa nkịtị na-ahọrọ SATA SSD.
Ihe gbasara SATA
SATA bụ Serial ATA (Serial Advanced Technology Attachment), nke a makwaara dị ka Serial ATA, nke bụ nkọwapụta interface diski ike nke Intel, IBM, Dell, APT, Maxtor na Seagate kwadoro.
SATA interface na-eji eriri 4 na-ebufe data, nhazi ya dị mfe, Tx +, Tx- na-egosi mmepụta data dị iche iche, kwekọrọ, Rx +, Rx- na-egosi ntinye data dị iche iche, dị ka ihe kachasị eji diski diski ike n'ahịa, ụdị nke ugbu a na-ewu ewu bụ 3.0, nnukwu uru nke SATA 3.0 interface kwesịrị ịbụ tozuru okè, Ordinary diskore na SSD 2 HD5. nke 6Gbps, ọ bụ ezie na e jiri ya tụnyere interface ọhụrụ nke 10Gbps na 32Gbps bandwit e nwere ụfọdụ ọdịiche, ma nkịtị 2.5-inch SSD nwere ike izute kwa ụbọchị ngwa mkpa nke ọtụtụ ndị ọrụ, 500MB / s ma ọ bụ na-agụ na ide ọsọ zuru ezu.
