The newest version of Red Hat Enterprise Linux 6 forms the building blocks of the entire Red Hat portfolio, including OpenShift and OpenStack, making it a perfect foundation for enterprises looking to explore the open hybrid cloud.”-said Jim Totton, vice president and general manager of Red Hat Inc. Now lets take a closer look to the main highlights of RHEL 6.5 : 

Securing the Next-Generation Enterprise
Red Hat Enterprise Linux 6.5 continues the push for integrated security functionality that combines ease-of-use and up-to-date security standards into the platform. The addition of a centralized certificate trust store enables standardized certificate access for security services. Also included are tools that meet leading security standards, including OpenSCAP 2.1, which implements the National Institute of Standards and Technology’s (NIST’s) Security Content Automation Protocol (SCAP) 1.2 standard. With these additions, Red Hat Enterprise Linux 6 provides a secure platform upon which to build mission-critical services and applications.

Networking – When Every (Micro)Second Matters
In the financial services and trading-related industries, application latency is measured in microseconds, not seconds. Now, the latest version of Red Hat Enterprise Linux 6 fully supports sub-microsecond clock accuracy over the local area network (LAN) using the Precision Time Protocol (PTP). Precision time synchronization is a key enabler for delivering better performance for high-speed, low latency applications. Red Hat Enterprise Linux 6.5 can now be used to track time on trading transactions, improving time stamp accuracy on archived data or precisely synchronizing time locally or globally. Thanks to other networking enhancements in Red Hat Enterprise Linux 6.5, system administrators now have a more comprehensive view of network activity. These new capabilities enable sysadmins to inspect IGMP (Internet Group Management Protocol) data to list multicast router ports, multicast groups with active subscribers and their associated interfaces, all of which are important to many modern networking scenarios, including streaming media.

Virtualization Enhancements
Red Hat Enterprise Linux 6.5 continues Red Hat’s commitment to improving the overall virtualization experience and includes several improvements that make it a compelling choice for running in virtualized environments. Sysadmins can now dynamically enable or disable virtual processors (vCPUs) in active guests, making it an ideal choice for elastic workloads. The handling of memory intensive applications as Red Hat Enterprise Linux guests has also been improved, with configurations supported for up to 4TB of memory on the Kernel-based Virtual Machine (KVM) hypervisor. The KVM hypervisor also integrates with GlusterFS volumes to provide direct access to the distributed storage platform, improving performance when accessing Red Hat Storage or GlusterFS volumes. Finally, guest drivers have been updated to improve performance of Red Hat Enterprise Linux 6.5 running as a guest on supported third-party hypervisors.

Evolving Ease-of-Use, Storage, and More
As application deployment options grow, portability becomes increasingly important. Red Hat Enterprise Linux 6.5 enables customers to deploy application images in containers created using Docker in their environment of choice: physical, virtual, or cloud. Docker is an open source project to package and run lightweight, self-sufficient containers; containers save developers time by eliminating integration and infrastructure design tasks. Red Hat Enterprise Linux 6.5 stays current with the advancements in Solid-State Drive (SSD) controller interface, introducing support for NVM Express (NVMe)-based SSDs. The NVMe specification aims to standardize the interface for PCIe-based SSDs and its inclusion in Red Hat Enterprise Linux 6.5 positions the platform to support an expanding range of future NVMe-based devices.

Improvements have also been added to improve enterprise storage scalability within Red Hat Enterprise Linux 6.5. It is now possible to configure more than 255 LUNs connected to a single iSCSI target. In addition, control and recovery from SAN for iSCSI and Fibre Channel has been enhanced, and updates to the kexec/kdump mechanism now make it possible to create debug (dump) files on systems configured with very large memory (e.g. 6TB).

Red Hat Enterprise Linux 6.5 makes it easier to track and manage subscription consumption across the enterprise, integrating subscription tracking into existing business workflow. Usability enhancements include support for remote access to Windows clients and servers that use a newer version of the RDP protocol, including Windows 7 and 8 desktops and Windows Server 2012.

Red Hat Enterprise Linux (RHEL) 6.3 Released & Globally Available

Posted by Avik Sarkar On 6/24/2012 05:41:00 pm

Red Hat Enterprise Linux (RHEL) 6.3 Released & Globally Available

Only six months after the release of RHEL 6.2. Red Hat officially announced the global availability of the next minor release of Red Hat Enterprise Linux operating system platform, Red Hat Enterprise Linux 6.3. Couple of months ago we got the Beta of RHEL 6.3 and with this final release Red Hat has tweaked the enterprise grade Linux distribution to add new capabilities in storage, virtualization, security, developer tools, file systems, scalability and performance.

Highlighted Features :-
  • Developer Tools: In addition to OpenJDK6 support in Red Hat Enterprise Linux 6, the newly introduced OpenJDK7 allows customers running Red Hat Enterprise Linux 6.3 to develop and test with the latest version of open source Java. The Red Hat Developer Day is scheduled for June 26th at the 2012 Red Hat Summit & JBoss World. More about this and other capabilities will be presented, including the Red Hat Enterprise Linux toolset (updated GCC), performance optimization, thread programming and NUMA. For more information about developer day, please visit here.
  • Virtualization: Red Hat Enterprise Linux 6.3 helps smooth migration to a virtualized environment. This is achieved with the help of new Virt-P2V tools that can easily convert a Red Hat Enterprise Linux or Microsoft Windows system running on physical hardware to run as KVM guests. This release implements a more robust mechanism to protect data associated with defunct virtual machines. The method by which virtual disk images are securely wiped has been enhanced to allow greater security and stronger compliance with Payment Card Industry Data Security Standards (PCI-DSS).
  • Security: Users can now use two-factor authentication for securely accessing their Red Hat Enterprise Linux environment. This type of authentication mechanism is more secure than simple password based authentication. Two-factor authentication is being adopted into enterprise environments and is often referenced in industry standards. Red Hat Enterprise Linux 6.3 also includes advanced encryption capabilities so data blocks can be encrypted in parallel by taking advantage of underlying multi-processor capabilities. This is supported by the introduction of AES-CTR (Advanced Encryption Standard Counter Mode) cipher for OpenSSH. AES-CTR is well suited for high-speed networking environments.
  • Scalability: Red Hat Enterprise Linux 6.3 continues to test the outer bounds of scalability for an operating system platform by increasing the maximum number of virtual CPUs (vCPUs) per guest to 160 from 64. This is significantly higher than the 32 vCPU per guest limit for VMware ESX 5.0. The maximum supported memory configuration for KVM guests has also been increased from 512GB to 2TB.
  • File Systems: File system improvements include O_DIRECT support in FUSE (File system in user space). When enabled, all FUSE reads and writes go directly to storage, bypassing the server cache. This capability can lead to more consistent response times and predictable access to data by multiple accessors for certain use-cases, including database writes and deduplication. GFS2 (shared storage file system) can now read and write data to the disks faster than in previous releases for certain use-cases. In addition, file system check utilities for GFS2 can now be used to check the integrity of the older GFS1 file system.
  • Storage: The Logical Volume Manager (LVM) now provides support for RAID levels 4, 5, and 6 to simplify overall storage administration by consolidating all management functions, such as creating and re-sizing volumes, deploying RAID, and taking snapshots into a single interface. It is now possible to deploy Red Hat Enterprise Linux 6 as a FCoE based storage target server providing the high level of reliability and performance available with native Fibre Channel but at a significantly lower cost. This feature complements the FCoE Initiator support that was delivered in Red Hat Enterprise Linux 6.0.
  • Subscription Management: With Red Hat Enterprise Linux 6.3, by default customers can use Red Hat Subscription Management (SAM), an enhanced subscription management capability using X.509 certificates that allows customers to effectively manage subscriptions locally and report on subscription distribution and utilization. This helps facilitate compliance, upgrades, and long-term planning. Customers register their systems using Red Hat Subscription Manager to the Red Hat award-winning customer portal or an instance of Red Hat Enterprise Linux SAM. Customers who used RHN Classic subscription management with prior releases of Red Hat Enterprise Linux, can continue to use it or migrate to Red Hat Subscription Management.

Fedora 18 Added UEFI Secure Boot (Security-Key Purchased From Microsoft)

Posted by Avik Sarkar On 6/04/2012 02:08:00 pm

Fedora 18 Added UEFI Secure Boot (Security-Key Purchased From Microsoft)
 
Many of us knows that Microsoft has been pushing hardware vendors for Secure UEFI as part of Windows 8. The tldr version of UEFI is that it's secure encryption on the physical hardware at the pre-boot layer. Basically in order to boot the hardware will have to have a secure key. But while making UEFI a very basic problem arose and that is it won't easily allow people to load Linux. To get rid of this burning issue Red Hat's Fedora Linux has a solution and it's not one that is entirely satisfactory. Fedora will buy a key via Microsoft that will enable it to run. This is the solution now being offered up by Fedora developer Matthew Garret (and his blog post has fantastic details about the whole concept and the deliberation)
The key costs $99 and the funds go to VeriSign (though hardware signing is done via Microsoft). The problem of course is that Fedora will perhaps be tied to Microsoft's Secure UEFI efforts in order to enable Linux on new hardware. The bigger problem would be if Secure UEFI wasn't dealt with and Linux wouldn't run on new hardware at all.
After eliminating options of creating their own Fedora key or an overall Linux key as too complex or costly, Garrett says they have decided to opt for the "least worst" option; have Microsoft sign Fedora. So for $99, Microsoft offer a signing service and this should ensure compatibility with a wide range of hardware. "If there are better options then we haven't found them" he added.

Microsoft Gets Recognition Among Top 20 Linux Kernel Contributors

The Linux Foundation announced the top Linux kernel development contributors, with Microsoft getting on the list for the first time. The top 10 contributors to the Linux kernel in this latest report include "Red Hat, Intel, Novell, IBM, Texas Instruments, Broadcom, Nokia, Samsung, Oracle and Google," according to the report. For the first time, Microsoft has made the list of the top 20 contributors to the Linux kernel. Microsoft placed at No. 17 among companies that have contributed the most toward developing the Linux OS's kernel. As the Linux Foundation's announcement pointed out, it represents quite a change from the time when Microsoft CEO Steve Ballmer called Linux "a cancer" is now working within the collaborative development model to support its virtualization efforts and its customers. Because Linux has reached a state of ubiquity, in which both the enterprise and mobile computing markets are relying on the operating system, Microsoft is clearly working to adapt. In other words, some might recall the old adage: "If you can't beat 'em, join 'em.". The foundation suggested that Microsoft is "clearly working to adapt" in a world where Linux is used across enterprise and mobile environments.
The foundation's latest report, "Linux Kernel Development: How Fast It is Going, Who is Doing It, What They are Doing and Who is Sponsoring It," covers work completed through the Linux kernel 3.2 release, with an emphasis on the releases made since the last update to this report in December 2010 (2.6.36 to 3.2). 

Since 2005, there have been more than 7,800 developers contributing to the Linux kernel, according to the announcement. The foundation also claimed that "75 percent" of Linux kernel developers get paid for doing it. The full report, "Linux Kernel Development: How Fast It is Going.

Red Hat Enterprise Linux (RHEL) 6.2 Released

Posted by Avik Sarkar On 12/07/2011 02:56:00 pm



After RHEL 6.2 Beta now Red Hat the world’s leading provider of open source solutions, today announced the general availability of Red Hat Enterprise Linux 6.2. With this milestone, Red Hat includes many enhancements that deliver benefits spanning multiple areas, including performance and scalability. Red Hat Enterprise Linux 6 operating system achieved the largest multi-core Linux configuration results certified to-date on the two-tier SAP® Sales and Distribution (SD) standard application benchmark.1 Proven to perform and scale, Red Hat Enterprise Linux 6 effectively supports large, mission-critical enterprise computing environments.
Vice President and General Manager, Platform Business Unit at Red Hat, said, “The exciting features in Red Hat Enterprise Linux 6.2 with new impressive SAP® benchmark results allow our enterprise customers to have increased confidence that Red Hat Enterprise Linux 6 can run their enterprise workloads with high performance across physical, virtual and cloud computing environments.”
Enterprises can confidently migrate to the latest multi-core technology with Red Hat Enterprise Linux 6. On the latest two-tier SAP SD standard application benchmark, Red Hat Enterprise Linux 6 achieved more than 22,000 SAP SD benchmark users on a single system. On this same benchmark, the HP DL980 G7 system running Red Hat Enterprise Linux 6 fully utilized all 80 cores and 160 threads in the 8-processor system running MaxDB 7.8 and the SAP enhancement package 4 for the SAP ERP 6.0 application. This is the largest Linux result submitted to SAP to-date. The results demonstrate the capabilities of the HP ProLiant DL980 G7 8-processor system’s PREMA architecture and smart CPU caching technology. Results are as of December 2, 2011, certification number 2011052.
“Clients need solutions to automate, scale-up or virtualize their environments to best fit their business requirements,” said Martin Whittaker, vice president, Systems and Solutions Engineering, Enterprise Servers, Storage and Networking at HP. “Optimizing Red Hat Enterprise Linux on HP ProLiant DL980 systems extends the power of open source to HP Converged Infrastructure, delivering uptime, increased capacity and faster processing speeds.”
Red Hat Enterprise Linux 6.2 delivers significant improvements in resource management and high availability, as well as new features aimed at storage and file system performance and identity management. Red Hat Enterprise Linux 6.2 provides additional capabilities to manage system resources. For service providers or internal IT organizations that deliver applications or hosted services via multi-tenant environments, maximums can be set for CPU time associated with a given application, business process or a virtual machine. This allows for more efficient management of SLAs and enables the ability to implement service priorities, similar to those associated with network Quality of Service (QoS).

When an enterprise deploys its applications to run in a Red Hat Enterprise Linux 6.2 guest hosted by VMware, the applications can now be utilized for High Availability (HA) Add-Ons. This also includes full support for use of GFS2 shared storage file system by the virtual machines. The result is additional deployment flexibility for customers requiring HA within a portion of their virtualized environment, as well as full support for Red Hat Enterprise Linux on the VMware hypervisor.

Red Hat Enterprise Linux 6.2 adds enhancements to storage and file system features including full support of iSCSI extension for RDMA. Now, benefits of low latency and high throughput through a standard SAN implementation based on 10Gb Ethernet are available to even the most demanding storage environments. This allows customers to opt out of expensive Infiniband hardware or other dedicated interconnect fabrics. Other enhancements around file system include delayed meta data logging, asynchronous and parallel file system writes, as well as support for multiple active instances of Samba in a cluster which improves overall throughput and increases availability for large Samba clustered deployments.

Identity Management:-
In Red Hat Enterprise Linux 6.2 provides the administrative tools to quickly install, configure and manage server authentication and authorization in Linux/Unix enterprise environments, while still providing the option to interoperate with Microsoft Active Directory. This enables enterprises to manage Linux infrastructure easily and cost-effectively. Centralized identity management and host-based access control can reduce administrative overhead, streamlines provisioning and improves security.

Performance:- 
Is key to all customers. Red Hat Enterprise Linux 6.2 continues to put an emphasis on accelerating I/O such as network traffic steering to improve network throughput by as much as 30 percent in performance tests conducted by Red Hat and delivering numerous file system enhancements that reduce read-write times and boost overall system utilization.

Red Hat expects to deliver the beta for Red Hat Enterprise Linux 5.8 later this month. Also fully underway is development for Red Hat Enterprise Linux 7, the next major release of Red Hat Enterprise Linux. Red Hat received an outstanding response from all Red Hat subscribers – users and partners – for requested features coming from the recent Red Hat Enterprise Linux 7 Ideas discussion group posted on the Red Hat customer portal. This important feedback allows Red Hat to continue to make Red Hat Enterprise Linux a computing foundation for the next generation of operating system platforms.
