RAID-DP (usually) is NetApp's name for what's essentially a RAID6.

RAID5/6 work fine for databases, just like RAID10 you have to size it correctly accounting for your read/write load.

Really any form of RAID (if you need the size) with as much RAM and SSD caching is the way to go these days.

Or just use colored optics and a passive mux.

Unless you're going hundreds of miles (at which point FC has probably broken anyway due to latency expectations) you don't need active DWDM kit, passive muxes are a much better solution, and far cheaper.

Ethernet most certainly is a broadcast technology, and it and IP have supported multicast for many years (IP multicast across several networks is very common on research networks).

As for bandwidth, assuming 20Mbit streams (fairly standard BluRay, broadcast in some parts of the world approaches it as well) you can fit 500 channels on 10G. In practice as you only have to send out what at least one client has requested you can have more channels then can be streamed, cable companies do this already with Switched Digital Video.

That's almost entirely false. (ISP network engineer in Australia here)

The major cable leaving Australia for the last decade has been Southern Cross (there's more now) and the Australian government have no significant interest in it (the NZ government on the other hand does by way of cable system part owner Telecom NZ).

iTunes downloads (at least some of them) are cached by Akamai, and traditionally most medium to large ISPs hosted Akamai caches inside their network (at $JOB[-1] Akamai was ~30% and Google was ~15% of all bandwidth used for a regional education network).

It truly isn't any different for any other CDN, some host inside Australia and peer with local networks (IIRC Limelite do this), some only host in Asia (eg Amazon), and some (eg Steam) install machines inside ISPs for their customers.

Well the Microsoft campus nearby does:

I actually *am* a network engineer, working daily on Google's backbone.

Actually the knowledge tested for in interview's isn't that great (certainly not enough to be productive on day one), but as with others it's the proven ability to learn that counts.

No you don't. (Network engineer working for a major global carrier in Australia)

*US* carriers will sell you T1/T3 lines, but they're not to the local standards. Australian standard lines are E1/E3 (Euro) or more commonly E1 PRI's (AKA Telstra Onramp).

Of course none of that matters for data as almost everyone just uses Gig-E (or 10ge) over single mode fibre these days, although some carriers still hold a torch for SDH/SONET.

Yes, it's a great skill to be able to setup a Cisco from the CLI, but it takes 1/10th the time from the GUI.

Er, no. For anything larger then a trivial config the CLI is much faster, and that's if you type it. Use templates (as most larger configs will) and it's not even close.

I'm pretty sure Jeremy's an American these days (or still British). You're thinking of Andrew Tridgell who is most certainly Australian.

My T410 switched to the multitouch gestures for one X revision a few months back, then X changed back and I haven't been able to it since.

The only real bit of the T410 touchpad I had is the stupid little bumps on it.

From friends at Oracle isn't the official answer to use a VM from one of their "Clouds"?

I work for one of the companies that does the *large* proxies for education.

Until iOS 4 even the Apple apps don't use proxies correctly, with iOS 4 apps *can*, but pretty much *don't* use them.

The big problem with this is people buying tech and just expecting it to work. Sure this *should* be the case, but it's not, and people seem to have grasped that about PC OS', why not other devices that try to use the Internet.

Mine uses ADP as well, but Evince on Linux works fine for me.
