I-NVMe ngaphezulu kwe-TCP: i-craze yakamuva evela kunjiniyela we-Oracle

U-Alan Adamson igama likanjiniyela we-Oracle othumele le phrojekthi. Usebenza ekuthuthukiseni i-Linux kernel ye-distro yale nkampani, futhi manje usethole isingeniso sokuxhuma isitoreji se-NVMe nge-TCP.

I-Oracle Linux UEK5 Yinguqulo eyethulwe yi-NVMe kuma-Fabrics, ngaleyo ndlela ivumela imiyalo yesitoreji se-NVMe ukuthi idluliswe kumanethiwekhi afana ne-Infiniband noma i-Ethernet isebenzisa i-RDMA, zombili ezisetshenziswa kakhulu ezindaweni ze-HPC nezedatha. Kuhlobo lwe-UEK5U1, lokhu kusekelwa kunwetshiwe futhi ukuxhasa iziteshi ze-fiber optic.

Manje ku-UEK6 lokhu okusha I-NVMe ngaphezulu kwe-TCP, ephinda inwebe okungenhla ukusekela i-Ethernet ejwayelekile ngaphandle kokuthenga i-hardware ehambelana ne-RDMA yenethiwekhi yendawo.

Manje uma uzibuza yini leyo mayelana ne-NVMe nge-TCPKufanele wazi ukuthi imodeli emigqeni eminingi ye-NVMe isebenzisa kuze kufike ku-64.000 I / O yokuthumela nokuqedela olayini, kanye nokuphathwa okukodwa kokuthumela ulayini nolayini owodwa wokuqedela ngaphakathi kwesilawuli ngasinye se-NVMe. Ngomlawuli we-NVMe onamathiselwe nge-PCIe, le migqa isetshenziswa ngememori yokusingathwa futhi yabiwa yizo zombili ama-CPU aphethe kanye nomlawuli we-NVMe.

I / O ithunyelwa ku Idivayisi ye-NVMe lapho umshayeli wedivayisi ebhala umyalo kulayini wokuthumela bese ebhala ilog ukwazisa idivayisi yalo mcimbi. Lapho umyalo uqeda, idivayisi ibhalela umugqa wokuqedela i-I / O futhi idale ukuphazamiseka ukwazisa umshayeli wedivayisi ukuthi uqedile.

Umthombo: Oracle

NgeNVMe ngaphezulu kwezindwangu lolu hlelo oluyisisekelo lokuthumela nokuqeda ulayini kwimemori yokusingathwa luyanwetshwa ukuze luphindwe luphindwe ku isilawuli kude, ukuze umugqa womugqa osuselwe kumsingathi ubalulwe kumugqa womugqa osuselwe kusilawuli. Okuthile okungenangqondo kwe-PC kepha kwemishini ye-HPC namaseva kungathakazelisa kakhulu ekuxhumaneni okukude phakathi kwama-node ...
