Oracle yatulutsanso kusintha kwachiwiri kwa Unbreakable Enterprise Kernel R6, yoyikidwa kuti igwiritsidwe ntchito pogawa Oracle Linux ngati m'malo mwa phukusi lokhazikika ndi kernel yochokera ku Red Hat Enterprise Linux. Kernel ilipo pa x86_64 ndi ARM64 (aarch64) zomangamanga. Magwero a kernel, kuphatikiza kugawanika kukhala zigamba pawokha, amasindikizidwa m'malo opezeka anthu onse a Oracle Git.
Enbreakable Enterprise Kernel 6 yakhazikitsidwa pa Linux 5.4 kernel (UEK R5 idakhazikitsidwa pa 4.14 kernel), yomwe imasinthidwa ndi zatsopano, kukhathamiritsa ndi kukonza, ndikuyesedwanso kuti igwirizane ndi mapulogalamu ambiri omwe akuyenda pa RHEL, ndipo amakongoletsedwa mwapadera. pogwira ntchito ndi mapulogalamu a mafakitale ndi zida za Oracle. Kuyika ndi src phukusi ndi UEK R6 kernel zakonzedwa Oracle Linux 7.x ndi 8.x.
Zosintha zazikulu:
- Pamagulu, chowongolera chatsopano cha slab chawonjezedwa, chomwe ndi chodziwika bwino pakusuntha ma account a slab kuchokera pa tsamba lokumbukira kupita pamlingo wa chinthu cha kernel, zomwe zimapangitsa kuti zitheke kugawana masamba a slab m'magulu osiyanasiyana, m'malo mogawa ma cache a slab kwa aliyense. gulu. Njira yomwe ikuperekedwayi imapangitsa kuti ziwonjezeke bwino kugwiritsa ntchito slab, kuchepetsa kukula kwa kukumbukira komwe kumagwiritsidwa ntchito pa slab ndi 50%, kuchepetsa kwambiri kukumbukira kukumbukira kernel ndikuchepetsa kugawikana kwa kukumbukira.
- Pazida za Mellanox ConnectX-6 Dx, dalaivala watsopano wa vpda wawonjezedwa ndi chithandizo cha vDPA (vHost Data Path Acceleration) chimango, chomwe chimakulolani kugwiritsa ntchito mathamangitsidwe a hardware kwa I / O yotengera VirtIO mumakina enieni.
- Zosintha zokhudzana ndi kuthandizira kwa zida za NVMe zatengedwa kuchokera ku Linux kernel 5.9.
- Kukonza ndi kuwongolera kwasungidwa pamafayilo a Btrfs, CIFS, ext4, NFS, OCFS2 ndi XFS.
- Madalaivala osinthidwa, kuphatikizapo lpfc 12.8.0.5 (Broadcom Emulex LightPulse Fiber Channel SCSI) ndi chithandizo cha 256-gigabit mode kwa SCSI Fiber Channel, mpt3sas 36.100.00.00 (LSI MPT Fusion SAS 3.0), qla2x0.02.00.103xXNUMX Fiber Channel XNUMX. HBA).
- Adawonjezera chithandizo choyesera cha VPN Wireguard, chokhazikitsidwa pamlingo wa kernel.
- NFS yawonjezera chithandizo choyesera kuti athe kukopera mwachindunji mafayilo pakati pa ma seva, ofotokozedwa mu ndondomeko ya NFS 4.2
- Wokonza ntchitoyo ali ndi luso loyesera kuti achepetse magwiridwe antchito ofunikira pamitundu yosiyanasiyana ya CPU kuti atseke njira zotayikira zomwe zimagwirizanitsidwa ndi kugwiritsa ntchito cache yogawana pa CPU.
