The only databases where tablescan performance matters is datamarts, for almost everything else it's random I/O as in most OLTP systems. Oracle and NTFS (SQL Server) both default to 4KB access units though I've gone as high as 16KB for Oracle and 64KB on NTFS (the max for current versions of NTFS)
About in line with FC 15k drive pricing. I know I would rather have an array full of those 512GB parts then full of 450GB FC drives IF the background defrag could keep up with our typical workload.
Cool, NFS and automount works great for a workstation or server with a very fast LAN connection to the NFS server, now how do you provide that same service to a road warrior?
How are you going to slip something into a signed package?!? That's the whole point in signing it, it can't be tampered with or the signature becomes invalid.
What about ongoing maintenance and modular base images? We've had that on Windows since forever where we can publish applications to a user and allow them to install in on first run without requiring administrator access.
Just remove RH's key and install your own corp key then only sign tested packages. This is actually kind of cool, now you just need an easy way to make package updates mandatory like with published apps in AD.
Google and just about everyone else is going to the model where you never touch the server after install. Also their evidence shows that too cool of temperatures negatively effect HDD life, that's quite different from saying warmer temperatures are better, it was also the area of the study that had the fewest number of datapoints so the evidence might not be fully accurate.
Uh, how about the fact that instead these works should be in the public domain as their continued copyright does nothing to promote science and the useful arts?
The artists and songwriters are the only ones getting paid for music on the radio. The stations pay ASCAP/BMI but pay nothing to the labels. In fact the labels often pay the stations to play their music (payola), but that's more TOP40 then oldies/classic rock.
I think HP had as much revenue from the networking division last year as this deal is valued at, I don't think they needed 3com to make a UCS competitor (they actually had one before UCS came out, c7000+Flex10).
I know it's a joke but Cisco is actually MUCH more like that on the networking side, HP offers lifetime warranties on the hardware and software updates are always free. The 5 year cost of a Procurve is a fraction that of a comparable Cisco switch. I still have all Cisco chassis based switches because they are bulletproof but on the economics side HP is definitely ahead.
Exchange hasn't been high I/O since 2007 and when 2010 launches it gets even better. A big enough environment might still see some decent IOPS but nothing like the same organizations DB environment in all likelihood.
You're making it a black and white issue, under your assumption it's either snake oil or it's a perfect cure. In the real world there are shades of grey and we are shooting for (and paying for) 99.9% black but are probably really getting 97% black when we get anything at all, many diseases go untreated because it's too expensive to develop a drug with a small potential patient set. What I'm proposing is relaxing things to a target of say 95% black when the disease warrants it. It's kind of like uptime in IT, most organizations don't need 5 9's uptime and can't afford it so they go for something more affordable which still brings significant benefits to the organization.

800/1600 tapes are $50 and can be sent multiple times by courier. HDD's are almost there on cost/GB but that technologies already a few years old.

HD5750 silent launches next week
Try a 256KB CGA card for an XT clone. Two full length slots, so about twice the size of most current generation cards.
Yes but I just got a brand new (2 month old) 500GB HDD for $56 last week.
Haven't touched my Banshee or 3000 since I found out about GLIDE wrappers that work with D3D =)
There's a silent 5750 coming out next week. Low power, silent, but able to play anything out there.

Not much at all, delta-t is too low to get any real efficiency.
Uh, Boot and System volumes can in fact be different. The GUI mode setup might not let you do this but multibooters have known it for years.

That's a change, you used to have to change the extension to .zap or something else.
gmail doesn't allow zip attachments for this and so many other reasons.
Uh, if they are eating their own dog food wouldn't they already be running Procurve internally? Much better than switching to 3Com, shudder....

Silent bit errors on current server class hardware should be vanishingly small, the buses and memory are protected by ECC.
