[New] Kernel Linux 3.2 Sudah Dirilis

Posted by —

Setelah tujuh kali mengeluarkan rilis kandidat, Linus Torvalds mengumumkan pada tanggal 4 Januari 2012, ketersediaan download segera untuk kernel Linux 3.2.

Di antara fitur-fitur baru yang ada pada kernel Linux 3.2 ini, kita bisa menyebut dukungan yang lebih baik untuk file besar dengan mendukung ukuran blok yang lebih besar dari 4KB dan sampai 1MB di EXT4, batas atas dari waktu CPU sekarang bisa ditetapkan dalam proses scheduler, banyak perbaikan Btrfs, dan masih banyak lagi.

Berikut ini pernyataan dari Linus Torvalds (link):

“So 3.2 is out, and the merge window for 3.3 is thus officially open.

I delayed 3.2 first a few days to wait for the final linux-next (“final” in the sense that that’s what I’ll fetch to decide whether something has been in linux-next for 3.3 or not), and then some more as people were coming back from holidays and sorting out some regressions. So we do have a few last-minute reverts and small fixes.

Still, there’s not a whole lot of changes since -rc7 (shortlog appended), and almost all of them are *tiny*. So despite the few annoying last-minute reverts, I’m feeling pretty happy about it.“

Highlights of Linux Kernel 3.2:

· Support for bigger block sizes in EXT4;
· Faster scrubbing, detailed corruption messages, automatic backup of tree roots, and manual inspection of metadata in Btrfs;
· Process bandwith controller;
· Support for the Hexagon architecture;
· Thin provisioning and recursive snapshots in the Device Mapper;
· I/O-less dirty throttling, reduce filesystem writeback from page reclaim;
· TCP Proportional Rate Reduction;
· Improved live profiling tool “perf top”;
· Cross memory attach.

Kernel Linux 3.2 juga membawa banyak perbaikan untuk berbagai filesystem yang didukung, seperti ext3, CIFS, JFFS2, EXOFS, NFS, GFS2, dan squashfs.

Red Hat Enterprise Linux 6.1, yang merupakan update pertama untuk tambahan dalam baris produk Red Hat Linux terbaru, baru saja dirilis. RHEL 6.1 datang enam bulan setelah rilis pertama dan telah membundel semua patch keamanan dan perbaikan keamanan.

Update ini juga membawa beberapa fitur dan teknologi baru, mudah dimengerti, kebanyakan ditujukan untuk konfigurasi pusat data yang kompleks serta lingkungan virtualisasi.

“With Linux adoption growing across all workloads, Red Hat Enterprise Linux 6.1 provides more enterprise reliability, performance and control throughout the datacenter,” Jim Totton, VP and general manager, Platform Business at Red Hat.

Update terbaru ini juga menambahkan dukungan yang lebih baik untuk beberapa konfigurasi perangkat keras dan perangkat terbaru, seperti PCI-E 3.0, yang sudah diluncurkan sejak November lalu ketika RHEL 6.0 dirilis.

“Red Hat Enterprise Linux 6.1 enhancements provide customers with improvements in system reliability, scalability and performance, coupled with support for upcoming system hardware,” Red Hat said in a statement.

“Red Hat Enterprise Linux 6.1 also delivers patches and security updates, while maintaining application compatibility and OEM/ISV certifications,” it added.

Salah satu bidang yang memperlihatkan beberapa perbaikan adalah dukungan untuk konfigurasi penyimpanan maju khususnya dengan FCoE (fiber channel over ethernet), Datacenter Bridging, dan iSCSI offload.

RHEL 6.1 memperkenalkan sebuah versi preview teknologi layanan Red Hat Enterprise Identity (IPA) yang didasarkan pada proyek sumber terbuka FreeIPA, yang sudah tersedia di Fedora. Daerah lain yang terupdate adalah virtualisasi, dukungan filesistem, scheduler dan sebagainya.

Red Hat Enterprise Linux supports the entire data center architecture and major infrastructure projects like:

  • Moving to IPv6 is easier with optimized networking, firewall and DHCP/DNS services.
  • Intelligent application consolidation using Control Groups functionality for resource control of applications and virtual machines.
  • Managing application uptime using transparent proxy or High-availability Add-Ons, that can fail-over applications, services or virtual machines.
  • Tracking Red Hat Enterprise Linux deployments and subscriptions by using the new Subscription Manager, currently only available with 6.1 and for use with RHN
  • Planning user authentication and authorization with LDAP, kerberos, AD integration or Red Hat Enterprise Identity (IPA) services, now in Tech Preview

Versi beta untuk RHEL 6.1 telah dirilis beberapa bulan yang lalu dan telah diuji sejak saat itu. Sekarang siap untuk dilemparkan ke pasar.
