What Will Be in Linux 2.7?
Realistic_Dragon writes "The first discussion has been sighted on the Linux kernel mailing list to put together a feature list of things that should go into Linux 2.7 - including hotplug CPU & Ram support, network transparent sound and improvements to Netfilter to bring it up to the the level of OpenBSD's Packet Filter. And all this before most of us have started to run 2.6.0-preX, or even a 2.6 series stable release happening. Perhaps if you have a (sensible) idea now would be a good time to voice it, otherwise you will have to wait for 2.9 to get it included."
I believe they're referring to some mainframes, in which there are bays of CPUs/RAM that can be swapped in and out while the system is running.
CPU hotplug support is not designed for removing the processor from your single-CPU x86 box.

Already there.

User friendly configuration has been done.
I'd settle for power management working right.
Good 64 bit support was added in what, Linux 1.2 or so. Digital (remember them?) borrowed Linus a few Alpha boxes for the purpose. One can still find the occasional kinks in less used applications, but the kernel has been working fine on 64-bit computers for a good while.
linux doesn't only ship with a timeshare scheduler. it includes both the SCHED_FIFO and SCHED_RR schedulers, which provide close-to-real-time scheduling capabilities. most pro apps in the audio realm use one or both of these. they can both be used alongside the SCHED_OTHER ("timeshare") scheduler.
what would be more interesting would be CPU cycle reservation, which is already present in OS X, and would be very useful for any streaming media software.
You have to be kidding right? Dump Veritas? What are you smoking? Veritas isn't just a Volume Manager/Disksuite it is a supported/planned and critical piece of your infrastructure! You rely on Veritas because you know it is tried, true and recoverable. The excellent relation of Sun and Veritas is a reason to use the platform just like Veritas on HPUX and other platforms. Your not just paying for the software, your paying for the support and paying for the mission critical needs that demand that solution. Veritas is an EXCELLENT package and nothing in linux comes close to the Veritas & Sun solutions on certified hardware. (And if you compare the linux solutions on linux certified systems with the same performance, manageability and support you get from sun i would like to see ONE vendor that can compare!)
I also don't believe you understand the usefullness of Sun (non linux)solutions. You keep on correlating the costs to acquisition. In the real world the hardware/software costs don't mean squat. Any large IT business knows that your biggest cost is employees, software, licensing, support and contractors.
For one, i can spend 32,000 on a 4 way 64 bit cpu machine with 8 gigs of memory, 500gb diskspace and have Hotswappable CPU's, a VASTLY supperior backplane, Vastly superior scalability in growth and a proven reliable architecture. You Can't buy ANY linux solution/Wintel solution that comes close to the Solaris/RS6000/HPUX based systems out there. As i've stated before there is only ONE vendor that offers a machine feature comparison to suns LOW END/MID RANGE v880's and it doesn't come close in comparison to power. For example the only linux enabled hot swappable cpu/backplane/intel solution is built on 4 700 mhz pentium 3 processors and costs 24,000 for the base system. My Quad 1.2ghz v880 out of the box doesn't require anything proprietary, but on the linux solution you have to run the vendors version of linux, the vendors version of the apps compiled and can only use the vendors approved addons. Sure sun is only one vendor, but solaris is solaris. There isn't a mix match of versions, releases or there isn't a version of solaris for my v880 that doesn't work on my e10k. I can grow with a common platform to support from 1 user to 65000+ users and even cluster to support from that point on.
You have to get your mindset away from free/cheap = better. You have to realize that in the business world the costs for platforms that are tried and true is expected and also minimal compared to the costs to keep it running.
I would rather run my 2 terrabyte financial application on a slower sun server because of the reliability, the proven architecture and HA features. You have to remember that in my case 5 minutes of downtime costs $137,000. Suddenly a $3,000 Veritas volume management solution and a $100,000 hardware platform not only is justifyable but almost even insufficient in itself if you break out the cost vs requirements ratio.
I can make my 3 Terrabyte Clarrion System, my Sun V880 Systems, my Sun 280/240r webservers and my solaris management workstations run for months at a time in pure harmony. The fact that NOTHING CHANGES ON A WHIM IS A GODSEND!! The stability, and slowness by which things change is the reason why businesses rely on such as the costs are far from just your hardware/os purchase price.
