Yes, that's why I said, "catastrophically destroyed." It wasn't just a case of it screwing up a few things. The computer wouldn't boot. Opensolaris isn't including a safemode option, and it wouldn't even boot into single-user mode after editing the grub menu. My options for manual recovery are limited if I can't get to a shell.
Ahem! OpenSolaris' pkg image-update snapshots the entire root filesystem before the update. You can just do a simple restore of the ZFS files system Or boot the liveCD import the ZFS pool and do the restore from there.
That's exactly what Google and many others do, and they spend their money, and significantly less than this, on managing that storage effectively. It works. When it boils down to it, you can have all the exorbitantly expensive and brilliant 'enterprise ready' tools you want but the bottom line is you need redundancy - and that's pretty much it.
Google is not just any company. They build their own systems and don't just take off the shelf crap and use them anymore. If Google sold the hardware they made internally they could easily compete with Dell and Sun.
Go look at the Jobs @Google page and figure out why they need device driver developers and ASIC designers.
No body else does what Google does. They have 20K employees and a few thousand of those working on their Systems and Storage needs.
Most companies can't afford to hire so many people to run thier Data Centers.
Ahhh, shit. I'm heart broken. What I'd like to know is how a small business will handle a behemoth like that, how they'll fund the electricity for all those drives and who'll manage it all. I expect that will be an ongoing cost to Sun support;-).
Is this supposed to be some logical follow up to a real question?
I have news for you. People have been doing it for years, and the reason why Sun's business has gone down the toilet to commodity servers, Linux and Windows, especially with small businesses, for the past ten years is exactly for this reason.
People have been buying EMC, NetAPP, HP and IBM's expensive hardware for years as well and in higher volumes than those that do homebrew solutions. What is your point there?
You mean like using DTrace on OpenSolaris. I guess that would make OpenSolaris a perfect platform for google. OSS and tracing tools not to mention fault management.
The article claims that Sun is outsourcing Niagara, which is a 65Nm process to Fujitsu. This is absolutely false. Niagara is to debut in 2005-2006 according to Sun and on 90Nm technology not 2007.
Since the chip is already in the Sun labs how can it be 65Nm? No fab, in my knowledge, is ready for 65Nm yet,
http://aceshardware.com/read.jsp?id=65000293
Also sun never claimed to outsource all chip manufacturing to Fujitsu. The article is based on blurbs from unreliable sources, example geek.net.
This is the second IBM article to calim that Sun is outsourcing all chip desgin and manufacturing to fujitsu. Is this some sort of FUD IBM is trying to spread?
If a person still needs a account to login to iTMS with this bit of reverse engineered method, the Authentication hasn't been cracked!!!
Authentication cracked means that you cand take an encrypted password and retreive the plain text for and already existing account. All this guy seems to be able to do is figure out where and how iTunes sends its login information, so he can put it in his own application.
If you read the article Stallman claims runing Java on GNU/Linux as running a non-free software on a Free system. Thus claiming that GPL is a free license. His description of free software in the begining of the article, conviniently fails to mention the copyleft philosophy.
So Stallman describes free software and gives an example of a product under a copyleft license and masquerades it as free software. If you read the FSF website they clearly make a distinction between copyleft software, non-copyleft free software and free software.
http://www.fsf.org/philosophy/categories.html#Fr ee Software "Free software is software that comes with permission for anyone to use, copy, and distribute, either verbatim or with modifications, either gratis or for a fee. In particular, this means that source code must be available. "
http://www.fsf.org/philosophy/categories.html#No n- CopyleftedFreeSoftware "Non-copylefted free software comes from the author with permission to redistribute and modify, and also to add additional restrictions to it."
http://www.fsf.org/philosophy/categories.html#Co py leftedSoftware " Copylefted software is free software whose distribution terms do not let redistributors add any additional restrictions when they redistribute or modify the software. This means that every copy of the software, even if it has been modified, must be free software."
Clearly, the FSF makes a distintion between different degrees of freedom. But Stallman in the Article mixes and matches the two differnet philsophies to create and illusion of a so called java trap. When free software in conjuntion with a system protected by a copyleft license, like the GPL (GNU/Linux), will also work in his example of the trap.
Basically he is claiming that a piece of software is entraped because it is less free than the one it is dependant on. In the begining of the article he only mentions what the FSF clearly defines as "Free Software".
"Roughly speaking, they are: the freedom to run the program, the freedom to study and change the source, the freedom to redistribute the source and binaries, and the freedom to publish improved versions. (See http://www.gnu.org/philosophy/free-sw.html.) Whether any given program is free software depends solely on the meaning of its license."
Notice the term license. By definition of the GPL it is a copyleft license not free software. This again is FSF's own definiton page.
"In the GNU project, we use ``copyleft'' to protect these freedoms legally for everyone. But non-copylefted free software also exists. We believe there are important reasons why it is better to use copyleft, but if your program is non-copylefted free software, we can still use it."
Here he seems to suggest that copyleft is the way to go. One thing is certainly clear Stallman and the FSF spin the word "free" to mean many things.
Free software is free (no restrictions). copyleft (freedom with restrictions) is also free software? So why isn't Sun's jvm which is free (to mredistribute and monetarily) but incompatible with the GPL non free, becuase of frame of reference. The GPL is also then not free when placed in context with a license more free.
This is confusing to anyone who isn't well versed with the FSF lingo. Thus my request to Stallman.
I actually read the Stallman article (yeah I know this is slashdot). One thing bothered me as I read majority of the article is Stallman's use of GPL and free interchangebly.
My main problem is "free" means free. But in the GNU context "free" means "GPL'd". There is a problem here GPL'd software is not really free, it is freedom with restrictions. Java is also free software with restrictions, mainly not being able to modify it. GPL goes one step further allows modification but with the restriction that the modifications also be made freely available. Thus GPL is a little more free than Java but not completely free in the true sense of the word.
Suppose I released some software completely free. Free to use, modifiy and redistribute without realsing any of the modification under a new FSL (free software License). Said software would also be shackled when run with dependencies of GPL'd software which is not as free as the software I just released, lets call it the GPL trap. Or any software linked with GPL'd software must also be released under the GPL. Java doesn't require you to follow its licensing terms, one may release Java programs under the GPL.
As I have just illustrated, different degrees of freedoms exist in the world and mean different things to different people. Java is free, as in no monetary cost to use, GNU software is more free as in it is free to modify, but there is also a definiftion for free as in "no restrictions, no cost" which the GPL'd software like GNU/linux is clearly not. So I would like Mr. Stallman to please stop using the word free interchangebly with GPL'ed software, so as not to confuse readers.
Freedom is a deeply philosophical term of which excrutiatingly long discussions can ensue. However, Java is free, albeit with restrictions, GPL is a little more free but also with restrictions.
My girlfriend gave me a $200 gift certificate to an electronics store. It was a tough decision between a PS2 and an ipod, she couldn't make it either, hence the GC. The PS2 won. Becuase I didn't want to spend another $200 on the ipod.
The ps2 fit nicely in the $200 aligned gift certificate without allocating one more. Geeky?
Why use a U320 card if all you plan on connecting is one drive?
The bus bandwidth only comes into play if you have more than 4 disks on the SCSI bus. The max sustained bandwidth of a 10k RPM SCSI disk is ~70 MB/s. You would need a U320 controller if you plan on putting about 4 of these disks on the same bus that is 4x70 MB/s = 280 MB/s.
You could get away with an LSI logic single chanel U160 64 bit PCI controller for $46.75 shipped (pricewatch). Maxtor 10K rpm 73GB U160 drive can be had for $147 shipped.
So your total for SCSI with two drives = $294 + $47 = $341
Added bonus you can connect 15 drives to the SCSI controller and only 4 to the IDE RAID controller. you can get a dual channel lsi1010 controller for $64.
look again go to Dells site. Click on medium to large business and then price your servers.
The PE1750 with a 2.4 Ghz Xeon is $3714 starting.
For buisness with 200 on more employees dell is much much more expensive than Sun.
All of dells discounts evaporate at that time. Well agreed Sun doesn't differentiate between individuals, small business and large enterprises. But your post is way misinformed and incorrect.
A better way to say what you say is dell is cheaper than sun for small businesses because of all the massive discounts it puts out on it's sites.
I am sure sun offers similar discounts but not publically.
Anyway you slice it the v60x is cheaper than dell's lowest price offering in that market for enterprises (meaning companies with 200 or more people).
The OPs analogy was perfect. the 10.2.x updates you describe are hotfixes, and the 10.x are service packs
No. This analogy is false. Apple's version numbering is 10.X where X is the new release number based on the baseline Mac OS 10 architecture. 10.X.Y releases are service packs.
This is no different from Microsoft's release engineering versioning. Windows 2000 was based on NT and was versioned 5.0 and Windows XP based on windows 2000 is version 5.1. Just open a cmd window and look at the verison of XP it should say 5.1.0.xxxx.
Linux does the same thing with 2.X where X is even numbers for stable new releases and 2.X.Y is the number for fixes and minor updates.
There is a difference between marketing and release engineering verisoning.
Assuming that a Apple user only downloads songs legally through iTunes MS.
The 40GB ipod would hold $10,000 dollars worth of songs. That's a little too much change to be carrying around in you pocket don't you think. You could get mugged for that kinda dough.
Mugger: hand me you wallet.... no wait, Say, that's one of em new 40GB iPods ain't it, whats that iPod worth. Guy being mugged: I'd say about 5 grand, it's only half full. Mugger: Screw the wallet, hand me that iPod.
You gave me bestbuy prices I gave you best buy prices. Go to Bestbuy.com and look at the prices your self all the prices I gave are from bestbuy.com. schools won;'t go to 10 different locations to get components, they want one vendor.
You fail to also look at other factors favoring the emac.
1. One single piece means space saving. A biggie when real estate is scarce. Like in school lab where you need to put many computers in a room.
2. Power consumption and heat decipation. The emac is going to consume much less power than the emachines destop tower + monitor. Since the G4s run really cool you have less heat, less cooling costs (Air conditioning). Incase of the emachines you have the monitor generating heat as well as the tower. The emac has only one major heat source the CRT part. A biggie for school districts, whose budgets are already pretty restrictive, saving on thier electric bill is a good thing.
3. Less noise, quieter labs. AFAIK the emacs and the imacs have no fans. Have you ever heard and Athlon XP/P4 based pc (I have one in my room and it is LOUD) you have 5 fans minimum (cpu,chipset,gpu, power supply, 1-2 case). Now put 12-24 of these PCs in a room.
AS for iApps. Schools give home work, like papers, presentations and such. Students can get creative with thier work if those tools are present. And the schools save money buy not having to buy licenses for 3rd party apps for XP.
Add to XP antivirus software licenses. The cost of the hardware is often offest by the software licenses when you go for a windows solution.
One more thing, the education market never pays retail. Apple offers good discounts. The emac with 384 megs of RAM can be had for $789 with educational pricing. Emachines is already on very low margins I am not sure discounting thier products more will still keep them profitable.
To make your best buy emachine comparable you would have to add a 32 MB radeon for $129.50 and a flat CRT 17" like the emachines eview monitor 17F/17F2 for $209.99
Emachines PC $399.99 32MB Radeon $129.99 17" Flat CRT $209.99 Total $ 739.48
Cheapest emac $799
Difference is $59.50
Ok so $9.50 more than $50, You win!!!
I think to really make it more comparable Windows XP home should be replaced with XP pro to match MacOS X's networking features. And also the iApps. So there goes the difference in proce. The mac looks better even with a slower CPU.
The author of the article claims he reinstalled his powerbook. And tried to redownload his purchased songs after changing his address permantly on both his credit card and iTunes to an outside US address.
Well that doesn't say apple will suddenly disable all your music files if you step out of US soil for say a week or a month.
Apple'sn policies clearly state that you may only purchase songs in the US.
After sitting through two days of PCI-Express and PCI-X presentations at he pci-sig devcon.
The developers and the SIG most certainly weren't rubbing thier hands with a devilish grin saying "we got the suckers, let's lock them into a new upgrade cycle for another decade, Ha Ha Ha". The motivations for PCI Express are very compelling.
First PCI-EXPRESS is not targeted only for the desktop. It is targeted to be a general purpose bus for all class of machines and has features built-in that make it very attractive for server platforms.
Advanced RAS features
With conventional PCI you can only detect single bit errors. And nearly any such error is fatal. For PCs you would just reboot but it is a big no-no for HA servers. With PCI-Express you can detect and correct errors and since it is packet based, the corrupt packet can be retransmitted.
Built-in Hotplug.
Hot-plug in PCI was an after thought. It is built into PCI-express. The NewCard and Sever IO modules are designed to make hot-plugging very easy and user friendly. Nowadays to hutplug a pci card you have to open the chasis with the new modules you can just plug it in/out from the back of the chasis without removing the entire server off the rack. Also the newcard formfactor makes it ideal for laptops and mobile devices. PCI and PCMCIA are going to merge eventually and use the same Newcard form factor.
Backward Compatibility is maintained
You don't have to throw out your old PCI/PCI-X cards. PCI and PCI-EXPRESS are designed to co-exist. All the motherboard manufacturer would need to do is connect a PCI-EXPRESS to PCI switch from the root complex and provide slots for PCI/PCI-X devices
New and interesting design opportunities.
PCI-EXPRESS allows the PHY to be a a cable. So you can percieve a system where the rootconmplex and the io are in two or more seperate chasis connected by a cable. This will make it more intuitive for upgrades. End users wouldn't have to open thier cases all the would need to do is unplug the rootcomplex case and replace it with a new one or similary the io case or graphics case.
Also the Mini PCI-Express card is half the width of the current mini pci card. Allowing two cards to be placed inside a laptop with the same real estate. The platform design choices could be endless.
You are comparing a box a yet to be released box with 1.5ghz Itanium2 (EA 10/22/2003) to a box with 563Mhz CPU released in 2001.
How is that indicative of OS performance?
Also 2003 is brandnew solaris 8 was released in 2000. Solaris 9 has quite a few performance improvments than 8 so I think the comparison is unfair on all counts, so please check your facts before you posts.
How do you plan on fitting 3*120 GB disks a 2100+ Athlon + heatsink and fan, 2 * cdrw drives into a standard 1RU chasis? You must perform miracles for a living.
My harddisks with just 2 in a case kept crapping out because of heat in my PC with a 1700+ Althon XP and one fan. I would love to see the $100 1U case you are buying
It depends on the hardware you are talking about. Solaris is an enterprise class OS. What that means is it is more suited to run on an enterprise class systems and run an enterprise on.
Apart from supporting oodles of memory(tera bytes) and CPUs (106). An enterprise class system needs to provide Enterprise class serviceability. Serviceabilty is probably the most understated of all the things talked about on slashdot.
How does linux point out to the service engineer which memory module of the hundreds on an huge server is faulty so he/she can replace it? What about debugging. Say the kernel panics for whatever reason how do you debug it? Having the source is no help if you can't get a stacktrace and debug a live system at a debug prompt. On Solaris you send the core dump to Sun or the FE/Sun Engineer can boot into the OS run mdb/adb on the coredump and debug at the customers site. Or boot with kadb and debug a live system. How do you do that in linux.
What about architectural things like changing the VM system mid kernel release? Say I have a panic on a customers site caused by a VM bug for which the fix lies in an kernel version 2 releases later. Now linus in all his infinte wisdom decided to accept a full VM rewrite in between then. Now The customer is screwed. We can't fix this because we can't move the customer to the latest release as it would need a full regression test to be done. We are not talking about a PC here, we are talking about hardware that costs hundreds of thousands to millions probably running a billion dollar business where uptime is important.
So until linux can solve these problems. I think Sun need not worry, eventually they should but not now.

So Stallman describes free software and gives an example of a product under a copyleft license and masquerades it as free software. If you read the FSF website they clearly make a distinction between copyleft software, non-copyleft free software and free software.
http://www.fsf.org/philosophy/categories.html#F
"Free software is software that comes with permission for anyone to use, copy, and distribute, either verbatim or with modifications, either gratis or for a fee. In particular, this means that source code must be available. "

" Copylefted software is free software whose distribution terms do not let redistributors add any additional restrictions when they redistribute or modify the software. This means that every copy of the software, even if it has been modified, must be free software."

AS for iApps. Schools give home work, like papers, presentations and such. Students can get creative with thier work if those tools are present. And the schools save money buy not having to buy licenses for 3rd party apps for XP.
Add to XP antivirus software licenses. The cost of the hardware is often offest by the software licenses when you go for a windows solution.
One more thing, the education market never pays retail. Apple offers good discounts. The emac with 384 megs of RAM can be had for $789 with educational pricing. Emachines is already on very low margins I am not sure discounting thier products more will still keep them profitable.
To make your best buy emachine comparable you would have to add a 32 MB radeon for $129.50 and a flat CRT 17" like the emachines eview monitor 17F/17F2 for $209.99
Emachines PC $399.99
32MB Radeon $129.99
17" Flat CRT $209.99
Total $ 739.48
Cheapest emac $799
Difference is $59.50
Ok so $9.50 more than $50, You win!!!
I think to really make it more comparable Windows XP home should be replaced with XP pro to match MacOS X's networking features. And also the iApps. So there goes the difference in proce. The mac looks better even with a slower CPU.
The author of the article claims he reinstalled his powerbook. And tried to redownload his purchased songs after changing his address permantly on both his credit card and iTunes to an outside US address.
Well that doesn't say apple will suddenly disable all your music files if you step out of US soil for say a week or a month.
Apple'sn policies clearly state that you may only purchase songs in the US.
After sitting through two days of PCI-Express and PCI-X presentations at he pci-sig devcon.
/. paranoia.
The developers and the SIG most certainly weren't rubbing thier hands with a devilish grin saying "we got the suckers, let's lock them into a new upgrade cycle for another decade, Ha Ha Ha". The motivations for PCI Express are very compelling.
First PCI-EXPRESS is not targeted only for the desktop. It is targeted to be a general purpose bus for all class of machines and has features built-in that make it very attractive for server platforms.
Advanced RAS features
With conventional PCI you can only detect single bit errors. And nearly any such error is fatal. For PCs you would just reboot but it is a big no-no for HA servers. With PCI-Express you can detect and correct errors and since it is packet based, the corrupt packet can be retransmitted.
Built-in Hotplug.
Hot-plug in PCI was an after thought. It is built into PCI-express. The NewCard and Sever IO modules are designed to make hot-plugging very easy and user friendly. Nowadays to hutplug a pci card you have to open the chasis with the new modules you can just plug it in/out from the back of the chasis without removing the entire server off the rack. Also the newcard formfactor makes it ideal for laptops and mobile devices. PCI and PCMCIA are going to merge eventually and use the same Newcard form factor.
Backward Compatibility is maintained
You don't have to throw out your old PCI/PCI-X cards. PCI and PCI-EXPRESS are designed to co-exist. All the motherboard manufacturer would need to do is connect a PCI-EXPRESS to PCI switch from the root complex and provide slots for PCI/PCI-X devices
New and interesting design opportunities.
PCI-EXPRESS allows the PHY to be a a cable. So you can percieve a system where the rootconmplex and the io are in two or more seperate chasis connected by a cable. This will make it more intuitive for upgrades. End users wouldn't have to open thier cases all the would need to do is unplug the rootcomplex case and replace it with a new one or similary the io case or graphics case.
Also the Mini PCI-Express card is half the width of the current mini pci card. Allowing two cards to be placed inside a laptop with the same real estate. The platform design choices could be endless.
Hope this will quell the
I believe the USIIIi have a built in 266MHz DDR controller. The ram is 266 MHz DDR.
You are comparing a box a yet to be released box with 1.5ghz Itanium2 (EA 10/22/2003) to a box with 563Mhz CPU released in 2001.
How is that indicative of OS performance?
Also 2003 is brandnew solaris 8 was released in 2000. Solaris 9 has quite a few performance improvments than 8 so I think the comparison is unfair on all counts, so please check your facts before you posts.
You should really check you facts before you post.

The last time I checked 1000 Mbps was 1 Gbps.
Wow, You must be a genius.
How do you plan on fitting 3*120 GB disks a 2100+ Athlon + heatsink and fan, 2 * cdrw drives into a standard 1RU chasis? You must perform miracles for a living.
My harddisks with just 2 in a case kept crapping out because of heat in my PC with a 1700+ Althon XP and one fan. I would love to see the $100 1U case you are buying
It depends on the hardware you are talking about. Solaris is an enterprise class OS. What that means is it is more suited to run on an enterprise class systems and run an enterprise on.
Apart from supporting oodles of memory(tera bytes) and CPUs (106). An enterprise class system needs to provide Enterprise class serviceability. Serviceabilty is probably the most understated of all the things talked about on slashdot.
How does linux point out to the service engineer which memory module of the hundreds on an huge server is faulty so he/she can replace it? What about debugging. Say the kernel panics for whatever reason how do you debug it? Having the source is no help if you can't get a stacktrace and debug a live system at a debug prompt. On Solaris you send the core dump to Sun or the FE/Sun Engineer can boot into the OS run mdb/adb on the coredump and debug at the customers site. Or boot with kadb and debug a live system. How do you do that in linux.
What about architectural things like changing the VM system mid kernel release? Say I have a panic on a customers site caused by a VM bug for which the fix lies in an kernel version 2 releases later. Now linus in all his infinte wisdom decided to accept a full VM rewrite in between then. Now The customer is screwed. We can't fix this because we can't move the customer to the latest release as it would need a full regression test to be done. We are not talking about a PC here, we are talking about hardware that costs hundreds of thousands to millions probably running a billion dollar business where uptime is important.
So until linux can solve these problems. I think Sun need not worry, eventually they should but not now.
