Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

Regressions in the installation programs of recent Linux distros
I have a Compaq Presario, 2001 factory refurbished vintage. It comes with the Compaq OEM Internet keyboard (a USB keyboard), an OEM version of the Logitech basic Wheel Mouse, 64 MB memory, a 20 GB Quantum Fireball disk. To this, I have added another 20 GB Western Digital disk, a 3COM 905B series Ethernet adapter, and an additional 256 MB stick of memory, bringing memory capacity to 320 MB and disk capacity to 2- 20 GB disks.
I have installed several versions of Linux. Mandrake and Red Hat are two of my favorites. The 8.0 and 7.1 versions of each installed flawlessly. Recently, I installed the new 8.1 and 7.2 versions, respectively. The Mandrake 8.1 version now has problems using the mouse during installation, and the Red Hat 7.2 version cannot even detect the keyboard.
I have two questions:
Any ideas what cause these regressions?
Are there any good workarounds or fixes available for either distro?
Thanks!

Re: Regressions in the installation programs of recent Linux dis
I have the exact same problem...
I have the new Presario 8000 serie with the AMD XP and the compaq USB internet keyboard. I tried to installed Redhat 7.2, but it couldn't detect the keyboard. Actually, I should say: it does detect it once in a while (once every 5 or 6 reboot).
It seems like before it loads the USB support from the kernel, the keyboard works fine (Numlock, caps lock works), but most of the time after the USB is loaded, the keyboard doesn't work aymore...
I don't know what's wrong, especially since I had Redhat 7.1 before on the same computer and it was working great!?
Thank you.
