I think it would be just as well if Apple ported the kernel to Xen and allowed it to be run on a Dom0 and additionally was allowed to run on non-Apple hardware.
Has anyone considered that the incessant whining and gimme gimme gimme attitude of the linux community as a whole is not good for the cause of open source? Try chaging the tone. Understand that it might take a while for a new product line to be available to all the marketing opportunities of the rest of business. It's called segmentation and that's that. There is no evil sly hand of Microsoft at work here. Just paranoia amongst a whole bunch of people who probably haven't even entertained the thought of buying a Dell system with Ubuntu on it.
If the demand is strong enough the market will be made. Don't expect to get too far with negativity though. At least Dell is offering it now. Can't say the same about all the other Tier 1 OEMs. Perhaps all the energy whining about Dell's offering should be spent and directed at Toshiba, HP, Acer et al for not offering it yet. When they start offering it, perhaps there will be COMPETITION amongst vendors and all the benefits that come to the consumer with said competition. Until then, it's all a bunch of empty whining to me.
Dell segments its business based on how customers are perceived to use their systems. This is why a consumer can't purchase a Latitude notebook, yet Small Business customers can. Support is also divided along these lines for the most part. You can purchase Gold Support "highly recommended" on business machines but not so on the consumer machines. Ubuntu Linux, as far as I can tell, is being offered as a consumer grade operating system at this time.
I would wager if you talked to the Small Business sales rep again you could still purchase an nSeries system with FreeDOS on it or you can purchase a Precision Workstation with Red Hat Linux. Simply go to www.dell.com/nseries.
Things like snapshotting, mirrorview, replication manager, disaster recovery, 4Gb ports, HW iSCSI, switched redundant fabrics, active/active pathing, and tons of cache are reasons to go for higher end storage systems.
Another option that fits between the DIY and EMC are something like the PowerVault MD arrays with HW iSCSI or not. iSCSI won't really compete with SAN until 10Gbit and even then Fiber will be on par as far as per port costs (that and it is established protocol). If going the MD route, investigate RHEL and GFS (formerly Sistina) it is a good product GFS2 will be ready for prime-time come Update 1.
Not enough specifics here. I am going to say do your thing. If it works, you're a hero and saved 47k. If it doesn't obfuscate and negotiate the 50k of storage down to 47k. Win for all.
Unless you would like to give more specifics. Cause I am going to say in 99% of cases where you want fast, reliable, and cheap storage you only get to pick two.
The only mindless zombies I see on a regular basis are the ones that assume everything Bush does is somehow inherently evil, destroying the constitution, causing global warming, etc. Those are the people I find who lack logic and reason and possess an inability to think beyond some handed down meme they read somewhere or heard somewhere and get patted on the backend by their circle of yes men.
Conformity through anti-conformity or what have you.
Leftists (I can't call them Liberals because that would mean free thinking people) are some of the most close minded, anti-freespeech people I have ever had an occasion to converse with.
Gov't really should be about equalizing misery and taking all the money from the doers and thinkers and giving it to the homeless and the crime ridden. Because, really, money is the solution to everything and the Gov't can just print more of it!!!! Those who make it, have too much, those who have a hand out can never get enough. Let's spread that misery around!!!
Dell needs to go full bore and create a true alternative to Windows that is marketed as such. Perhaps it should be a brand all its own so it doesn't interfere with the Dell brand. Kind of like Toyota has Scion and Lexus. The Dell "Scion" line of systems would be designed from the ground up to be open systems. Using only open source hardware and drivers. They would be packaged with a special Dell distribution, provided by RedHat/Novell/Shuttleworth or something rolled inhouse. The line of systems would be marketed and sold much as Mac OSX is today. An alternative. It would serve a niche market initially and expand from there (you can't expect doubledigit market penetration from the get go). The systems would be premium in nature, as evidenced by many on Slashdot and other forums people will pay premium for OSX tied to a premium hardware solution. The same would be expected of Dell's new Linux offering.
VMWare's hypervisor is capable of using VT and Virtualization capabilities of BIOS/HW to improve performance, provide more features.
Xen however is near native speed and doesn't require VT or Virtualization to run, but is enhanced by VT and Virtualization. VT and Virtualization for Xen allows FV machines to run "un-modified" OS.
Longhorn will be modified it appears to run in a Xen container (para-virtual). This will be interesting to say the least. The question is will I be able to run modified Xen OS in a Microsoft Virtualization Platform?
Can I run RHEL5/Virt or SLES10/Virt on a Lonhorn server? If so, cool. If not, why not?
Put simply, will Longhorn be a Dom0 and can I run RHEL/SLES/BSD/Solaris domUs. As well, can Longhorn be a domU running on a RHEL5/SLES/XenEnterprise Dom0?
Can NASA satellites or other satellites currently orbiting Earth detect our Aquifers? If so, perhaps the same instruments can be used on a probes sent to orbit Mars. If not, perhaps they should determine the method of detecting Earth's groundwater first, from orbit, and then export such tech to Martian probes.
Just my 2 cents.
Additionall, VT enables hardware virtualization, para-virt is still available to anyone running a Xen kernel which doesn't require VT enabled hw, just PAE enabled CPU which means anything P3 class or greater for the most part.
Maybe I am missing something...?
Security risk? I doubt that. If someone can compromise the host to install a guest on it.. and then cover up the tracks. Then VT is the least of your concerns!!!
dom0 knows about the domu(s). Now domu(s) don't know about other domu(s) but this is no different than separate physical boxes.
There is no inherent greater security risk with VT. If anything, when used properly, VT can enhance security situation as someone who compromises the domu can't get to dom0.
This is wrong. I am running FC6 on a D620 with Hardware VT turned on. The option is under POST Behavior. Certain processors that end in the E designation will not support VT, this is by design though.
They need to make a rippable high-definition CD format. It makes no sense to me to buy a SACD or a DVD-Audio and not be able to rip it to a format that will play on a PMP.
That, or online providers need to offer higher-end audio formats that can be burned to SACD / DVD-Audio. There are still people that care about the quality of the music on the medium.
Yeah. Cause in Canada nothing is printed in 2 languages.
Gimme a break.
The height of hypocrisy. I don't mind English / Spanish signage. I love America. Hundreds of languages are spoken here. English is the language most people use to do business and is the dominant language here, but that doesn't mean it is the only one.
The world is more connected than ever. We have to deal with this new paradigm. The economy is global, health and welfare is global, everything is global. We have nations, that are defined by borders, language, and culture. America is such a nation who's culture is inherently pick and choose, cafeteria culture. We implore people immigrating to our country to bring their talents, bring their language, bring their food, and the best things about their culuture (lore, art, music, philosophy, religion) etc and set up shop here. Leave behind the worst and strive for the best. That is America. Everytime I come back to this country, I literally kiss the ground.
I don't care if I get flamed. God Bless America!!
The problem is, if it requires a fetus of a certain age to come up with therapies... and you have poor women in one part of the world or country and rich people in another part of the world / country. What is stop them from setting up a market where fetuses are created (in women) and then aborted solely for someone else's health and being?
There are tricky ethical issues that have to be addressed and science operates, or should operate, within a code of ethics.
I was talking about the emerging and developing Eastern European nations, such as Poland, Czech Republic, etc. Some of which are new nations being admitted to NATO and the EU and are sometimes referred to as new Europe. BTW, Rumsfeld popularized it but it was certainly in the lexicon long before he did.
Just like the Americas were referred to as the "New World" at one point in time. Not so much now.
Fact of the matter is, the economies and countries that used to be held back by the Iron Curtain are emerging and Dell is investing heavily to serve those markets. Including putting a support center in Halle, Germany and a factory in Poland.
This is wrong. Randy Mott was the CIO (Chief Information Officer) not a Sales Exec. Further, Dell poached him from Wal-Mart which probably has one of the most impressive IT systems in the world.

There is a RHEL5 Client OS for Workstations and Desktop productivity. This is separate from the RHEL 5 Base Server and Advanced Servers.

No, HD over IP will end the format war.
