AS per usual the difficult but of clusters (esp at this level), isn't the code (quote "can easily be done" at the right level of efficiency), or physically linking the boxes,,,
but making the network linking up the thing.
# Sustained file system bandwidth of 50 GB/s for each color # Sustained external network bandwidth of 25 GB/s for each color
wow! That's not peak, but sustained..for me that's the impressive bit.
They called me Finbar (after Finbar Saunders) at Uni for fairly obvious reasons given my sense of humour, so I couldn't resist ramming the message home
They need someone 'up top' to say Concorde is a valid method of travel. - ie I use it so others can.
It works the other way too.
We had a new Managing Director, he got a BMW5 series instead of thr Jag the previous MD had. Therefor no other staff could have a better car than the MD and company car expenses dropped.
40 of their frequent flyers where killed in the WTC. Not only that, those 40 also authorised Concorde flights for their company's staff, so in that single day they lost a huge number of customers.
It was one of my dreams to fly on Concorde, but by the time I had the cash to allow me a special trip I had a family to support, so my priorities are now elsewhere.
yes blacklisting gets broke, given the current problem with RBL's....
Also RBL's should NOT be the only mechanism for spam blocking anyhow, you need a complete set of things: including whitelists, blacklists (homegrown or provided), baysian, simple text, virus filters.......an of course a policy to police the whole thing.
Secondary MX shouldn't deliver to a non-filtered internal email system., but should wait for the primary to come back up.
That way any filtering on the primary is also used if spammers use the secondary to deliver, mail continues to be delivered as normal, with no other changes.
Do a risk assessment, show the issues you have and the risk to business in cold hard cash.
ie the threat, the risk (impacty on the business), likelihood and possible ways of reducing the threat/risk with costs.
Present this info all the way up to the board of Directors, at the end of day they run the business and its there descision. You need to get a high level manager/director to sponsor this for you as well.
Alot of this kind of problem is getting the business (directors) to be aware of the problem and the threats to the revenue stream. If they choose to ignore any advice at leasat you've 'done your bit' and should be satisfied with that. Perhaps they'll come back in a few months with some positive results. Security is usually low on the adjenda, especially internal data security.
Heck, it's take me three years to get a semi decent computer room for physcially securing our engineering machines...and that was on done as it was required by the insurance company due to cost of replacing the hardware rather than the data!
I'm looking at rolling my own around a Dell server (dual power supplies etc, brand not that important), and transtec's (www.transtec.de) scsi based direct attached storage.
It runs ATA disks with a linux internal O/S and a SCSI connection.
that way I can control what protocols I run but putting *nix (FreeBSD being my choice but a GNU/Linux distro is equally well placed) on the front end server. Also links in with the rest of our systems which are still *nix.
Wouldn't surprise if they did move alot of their systems to Linux.
They where originally a Unix shop. Then about 3 years ago they went M$ as their strategic OS (ie all the desktops include CAD got moved + alot of the back end systems).
From the rumour I heard they got very badly burned by whole thing. I hear its working reasonably well now all their admins have got things bedded down, but it's still using more IT people than before!
Perhaps they've just seen the light of costs going from *nix to M$ or are doing due diligence of looking at alternatives, perhaps as a barganing chip like the UK govmnt did with their licence negotiations???
you've got to pay real money for the end server software, the SQL-server and all the really big latest fancy hardware to run it on a cluster (ok so the hardware might not need to be bleeding edge anymore).
You need lots of admins who need to pass their little exams and of course a company car for the remote admin:-)
When you can all this for 1/2 the people costs with a *nix, never mind the s/w costs if you go for a free-nix. Of course should you wish to goto big iron (SUN/IBM/HP and Oracle/DB2) alot of the skills are transferable.
Slashdot Mirror
well yes, but then they'd be blatently endorsing this open source stuff that they are trying to kill off.
(as opposing to just plain borrowing the code base and not keeping copyright - Windows TCP/IP stack looks very much like BSD's!)
Most M$ admins I know (and they started out as *nix admins) use perl for their scripting on both O/S's.
Will be interesting to see how the GUI generation get on with a proper scritping language.
for iSCI to work don't you need a network switch that talks iSCSI so you're QoS required doesn't drop?
goes off to cisco web site to find out more..

DO you guys get his name or not
Do you need a translation for the ghoulies bit and it's use in UK slang?
Thinking about email going outside the company, rather than integration with other clients and Exchange..
well we won't - non MS-mail app (Mainly eudora/kmail) and non MS O/S MacOS 9orX or Linux. on the desktop at work..
will be interesting to see how this works with non-MS email clients, esp on non-MS O/S's
OK then, not authorise - sponsor the expense!

is you use CRTL-C CTRL-V combo's (and others) it means I can keep my hands on the keyboard and not sliding off to find the mouse all the time.
Prob why I prefer the touchpad on my laptop to a mouse - my hands have less distance to move when typing/formating etc etc.
BTW CTRL-C CTRL-V works on most modern X-11 based apps.
is what u guys need in the States, without it you have no pivacy so get over it. (cf Scott Mcneally's comments on the subject).

must do more searching...
:-)
must not get caught googling all day at work..
As the use SPAM as part of their advertising (well U of P does anyhow).
:-(
Also one of the traditional UK Uni's (Liverpool) are using this route too. Not impressed
OK, so the guy who runs the local landfill will get all the prizes. Nice one.
Ok let me see, some dude who hasn't been vetted gets to open my mail and stick in a scanner.
Hmm I wonder how much it would take for me to bribe the people there to get personal info from the documents, couple of hundred AUS$ a month??
Small digital camera, or pencil and paper, or perhaps one of those spectacle camera's I keep getted spammed about is all it will take.
I wonder sort of security precautions these people take, you are after all giving them quite a level of trust with your presonal info.
Doing a risk assessment is the first step.
Then and only then can you properly secure the data with appropriate policies, and implement the policies with procedures and technology.
Then repeat every so often.
Remember security is a process!

Interesting coincidences...
1. Bush tries to get a Bill through Congress to update the US power grid and fails on budgetry issues (it costs too much)
2. The lights go out across a large chunk of the US.
3. The Bill is fast-tracked through congress...
Not that I'm implying anything, just stating the facts....
But what about the whole TCO?
:-)

Just a thought
