I-Oracle ikhiphe isibuyekezo sesibili sokusebenza se-Unbreakable Enterprise Kernel R6, ebekwe endaweni ezosetshenziswa ekusabalaliseni i-Oracle Linux njengenye indlela yephakheji evamile ene-kernel evela kuRed Hat Enterprise Linux. I-kernel iyatholakala kuma-architectures we-x86_64 kanye ne-ARM64 (aarch64). Imithombo ye-kernel, okuhlanganisa ukuhlukaniswa kweziqephu ngazinye, kushicilelwa endaweni yokugcina ye-Oracle Git yomphakathi.
I-Unbreakable Enterprise Kernel 6 isekelwe ku-Linux 5.4 kernel (i-UEK R5 yayisekelwe ku-4.14 kernel), ebuyekezwa ngezici ezintsha, ukuthuthukiswa nokulungiswa, futhi ihlolelwa ukuhambisana nezinhlelo zokusebenza eziningi ezisebenza ku-RHEL, futhi ilungiselelwe ngokukhethekile. ukusebenza ngesoftware yezimboni kanye nemishini ye-Oracle. Ukufakwa namaphakheji we-src ane-UEK R6 kernel alungiselelwa i-Oracle Linux 7.x kanye ne-8.x.
Izinguquko eziyinhloko:
- Kumaqoqo, kungezwe isilawuli sememori ye-slab esisha, esiphawuleka ngokuhambisa ukubalwa kwe-slab kusuka ezingeni lekhasi lememori kuya ezingeni lento ye-kernel, okwenza kube nokwenzeka ukwabelana ngamakhasi we-slab ngamaqoqo ahlukene, esikhundleni sokwaba inqolobane ye-slab ehlukene ngayinye. iqembu. Indlela ehlongozwayo yenza kube nokwenzeka ukwandisa ukusebenza kahle kokusebenzisa i-slab, ukunciphisa usayizi wememori esetshenziselwa i-slab kufika ku-50%, kunciphise kakhulu ukusetshenziswa kwememori okuphelele kwe-kernel futhi kunciphise ukuhlukana kwenkumbulo.
- Kumadivayisi e-Mellanox ConnectX-6 Dx, umshayeli omusha we-vpda wengezwe ngokusekelwa kohlaka lwe-vDPA (vHost Data Path Acceleration), olukuvumela ukuthi usebenzise ukusheshisa kwehadiwe ku-I/O okusekelwe ku-VirtIO emishinini ebonakalayo.
- Ukuthuthukiswa okuhlobene nokusekelwa kwamadivayisi we-NVMe kudluliselwe ku-Linux kernel 5.9.
- Ukulungiswa nokuthuthukiswa kufakwe kumasistimu wefayela le-Btrfs, CIFS, ext4, NFS, OCFS2 kanye ne-XFS.
- Abashayeli ababuyekeziwe, okuhlanganisa i-lpfc 12.8.0.5 (Broadcom Emulex LightPulse Fiber Channel SCSI) ngokusekelwa kwemodi engu-256-gigabit ye-SCSI Fiber Channel, mpt3sas 36.100.00.00 (LSI MPT Fusion SAS 3.0), qla2x0.02.00.103xXNUMX FiberXNUMX. HBA).
- Kwengezwe usekelo lokuhlola lwe-VPN Wireguard, olusetshenziswa ezingeni le-kernel.
- I-NFS yengeze ukwesekwa kokuhlola ukuze ukwazi ukukopisha ngokuqondile amafayela phakathi kwamaseva, achazwe ekucacisweni kwe-NFS 4.2
- Isihleli somsebenzi sinekhono lokuhlola lokukhawulela ukwenziwa okufanayo kwemisebenzi ebalulekile kumacores ahlukene e-CPU ukuze kuvinjwe amashaneli avuzayo ahlobene nokusetshenziswa kwenqolobane okwabelwana ngayo ku-CPU.
