I-Oracle yembuliwe muva nje ukukhishwa kwesibuyekezo sokusebenza sesibili se-Unbreakable Enterprise Kernel R6, ibekelwe ukusetshenziswa ekusatshalalisweni kwe-Oracle Linux njengenye indlela yephakeji elijwayelekile ne-Red Hat Enterprise Linux kernel.
I-Enterprise Kernel 6 engenakuqhekeka isuselwa ku-Linux 5.4 (UEK R5 ibisuselwa ku-4.14 kernel), ithuthukiswe ngezici ezintsha, ukulungiswa, nokulungiswaIbuye ihlolwe ukuhambisana nezinhlelo eziningi ezisebenza ku-RHEL, futhi yenzelwe ngokukhethekile ukusebenza ne-Oracle Hardware nesoftware yezimboni.
Okwalabo abangazi ngalokhu I-Kernel iguqulwe yi-Oracle, ibekwe njengesethi esithuthukile I-Linux kernel, ibekiwe ukuze isetshenziswe ekusatshalalisweni kwe-Oracle Linux njengenye indlela yephakheji ejwayelekile ye-Red Hat Enterprise Linux kernel.
I-Enterprise Kernel engenakuqhekeka (UEK) ihlinzeka ngemithombo emisha yomthombo ovulekile, ukulungiselelwa okubalulekile nokuvikeleka kwemithwalo yemisebenzi yefu nasesakhiweni.
Yi-Linux kernel enamandla i-Oracle Cloud ne-Oracle Engineered Systems, njenge-Oracle Exadata Database Machine ne-Oracle Linux kuma-Intel ne-AMD 64-bit noma amapulatifomu we-Arm 64-bit.
Ukukhishwa kwe-UEK 6 igcina ukuhambisana kweRed Hat okuhambisanayo kweKernel (RHCK) futhi ayikhubazi noma yiziphi izici ezinikwe amandla ku-RHCK. Izici ezingeziwe zinikwe amandla ukuxhasa izidingo zomsebenzi ezisemqoka kanye nezimagqabhagqabha ziyasetshenziswa ukwenza ngcono ukusebenza nokwandisa ikhenela.
Izici ezintsha eziyinhloko ze-Unbreakable Enterprise Kernel R6U2
Ukukhishwa kwe-Enterprise Kernel Ukukhishwa kwe-6 Update 2 kusekelwe ku-Linux 5.4 Kernel futhi kufaka phakathi ukulungiswa kwamaphutha we-LTS, okuneziqeshana ezingeziwe zokwenza ngcono ukusebenza okukhona nokuhlinzeka ngokulungiswa kwamaphutha amancane kanye nezithuthukisi zokuphepha. I-Oracle iyaqhubeka nokwenza ngcono futhi isebenzise izimbungulu ezibucayi nokulungiswa kwezokuphepha ku-UEK R6. Lokhu kubuyekeza kufaka phakathi izici ezintsha, ukusebenza okungeziwe, nokulungiswa kwamaphutha ezinhlotsheni ezahlukahlukene.
Kule nguqulo entsha yethuliwe singakuthola lokho ngamaqoqo, kungezwe isilawuli sememori esisha okuphawuleka ngokudluliswa kokubalwa kweslabhu kusuka ezingeni lekhasi lememori kuya ezingeni lezinto ze-kernel, okwenza kube lula ukwaba amakhasi wesilayidi emaqenjini ahlukahlukene, kunokuba kunikezwe amakhekhe e-slab ahlukile eqenjini ngalinye.
Indlela ehlongozwayo ivumela ukukhulisa ukusebenza kahle kweslab, ukunciphisa ubukhulu bememori esetshenziselwa amabhlogo kuze kufike kuma-50%, kunciphisa kakhulu ukusetshenziswa kwenkumbulo ye-kernel futhi kunciphise ukuhlukaniswa kwememori.
Olunye ushintsho olugqamile kuhlobene ngamadivayisi we-Mellanox ConnectX-6 Dx, ngoba ingeziwe umshayeli omusha we-vpda osekela uhlaka lwe-vDPA (vHost Data Path Acceleration), eyenza imishini ebonakalayo isebenzise ukusheshisa kwe-Hardio-based hardware ye-I / O.
Kubuye kuqhakanjiswe lokho ithuba lokuhlola lokukhawulela ukwenziwa okufanayo kwemisebenzi lisetshenziswa kusihleli somsebenzi kubalulekile kuma-cores ahlukahlukene we-CPU, ukuvimba iziteshi ezivuzayo ezihlobene nokusebenzisa i-cache eyabiwe ku-CPU.
Of ezinye izinguquko ezigqamile yale nguqulo entsha:
- Ukuthuthuka okufakwayo okuhlobene nokusekelwa kwamadivayisi we-NVMe kusukela ku-Linux kernel 5.9.
- Ukulungiswa okuhanjisiwe kanye nezithuthukisi ze-Btrfs, CIFS, ext4, NFS, OCFS2, kanye nezinhlelo zefayela le-XFS.
- Amashayeli avuselelwe afaka i-lpfc 12.8.0.5 (Broadcom Emulex LightPulse Fiber Channel SCSI) imodi engu-256 ye-Gigabit ye-SCSI
- I-Fiber Channel, mpt3sas 36.100.00.00 (LSI MPT Fusion SAS 3.0), qla2xxx 0.02.00.103-k (QLogic Fiber Channel HBA).
- Kungezwe ukusekelwa kokuhlola kwe-VPN Wireguard, okusetshenziswe ezingeni le-kernel.
- I-NFS ingeza ukusekelwa kokuhlola kokukopishwa kwefayela okuqondile phakathi kwamaseva njengoba kuchaziwe kusincazelo seNFS 4.2
Ekugcineni, uma unentshisekelo yokwazi okwengeziwe ngale nguqulo entsha ekhishiwe, ungaxhumana nemininingwane Kulesi sixhumanisi esilandelayo.
I-kernel iyatholakala ngezakhiwo ze-x86_64 ne-ARM64 (aarch64). Imithombo ye-Kernel, kufaka phakathi ukwehlukaniswa kwezimagqabhagqabha ngazinye, ithunyelwe endaweni yokugcina yomphakathi ka-Oracle.
