I admin the proxies for a mid-size company (~1800 users). The "Advertising" category is always the highest bandwidth category, and about 50% of used bandwidth. We're considering blocking the category company-wide.
FYI 15000RPM SAS drives will provide significantly more IOPs per disk than 7200RPM SATA drives
It's almost exactly double. As a rule of thumb, if you have a 10-drive 15k array, you can get the same performance out of a 20-drive 7.2k array. The problem comes in when people buy for capacity, not performance.
That's not the drive vendor, that's HP. Try getting an RMA for enterprise drives direct from a drive vendor sometime. They'll do everything they can to not honor the warranty. They only want to deal with vendors and VARs.
There is NO difference in reliability between "consumer" and "enterprise" drives.
That's not quite true... vendors continue fixing bugs in "enterprise" drive firmware when they almost never fix bugs in retail drives.
With that said, we've had terrible luck with a particular brand of 2TB SATA enterprise drives (think of the opposite of Eastern Analog) where we have to keep a shelf of hot spares so RAID 6 can rebuild in time for the next failure. I think we've had a >50% failure rate, but I'm not in that department any more so I'm not sure.
it is a very big [deal] due to the possibility of people dying as a result...either too much or too little.
I think most people will consider too much dying to be the problem, not too little dying.
I prefer Nexenta's feel. But a 4tb limit on the free option doesn't work for me and I had lots of issues with it's stupid cut down command line when you ssh in.
Nexenta is no-charge (non-commercial) for up to 18 TB of data (actual data on disk, not raw storage). You also get a normal bash shell by logging in as admin (instead of root) and using sudo.
My biggest complaint is getting used to ZFS ACLs when sharing to Windows systems, which I guess I'd have on any ZFS system.
WHY??????? HTML5 can play audio directly.
Duh, they didn't have HTML5 when Donkey Kong came out.
At work IT uses Onenote notebooks for documentation. I never tried it for video, but we've had good luck for it with text/images. No programming knowledge needed, adequate search, OCR/search of text in images. You can sync the content using a file share or Sharepoint, and probably WebDAV. I understand it's cost-free for Windows and Mac. You get a web interface if you use Sharepoint, but I don't care for it. If you're a primarily Windows/Office shop it might be worth testing.
Go look at the images. He's guilty of what the anon commenters accused him.
LOL, now you're getting sued, too.
If an NSA representative told me it was daytime outside and my watch said 12 noon, I would still walk outside to confirm it for myself.
Oh, like any of us have been outside.
Building storage with hard drives doesn't get you an article on Slashdot (or CNN); pretending you're going to build storage out of optical discs does.
If you don't want to maintain a system, then don't deploy it. Either pay someone to maintain it for you, or plan to maintain it yourself. You seem to want to be a hero and give unknowing non-technical users a complex system and then abandon it because it takes too much time.
With the amount of porn I consume, a discreet audio card is critical.
A third party has created an auto-update app.
- If a change is security related, and obviously needed, then why wasn't it made earlier? Didn't that make a mockery of all the "many eyes" arguments oft touted in favor of Open Source?
"Many eyes" rarely helps; you need to get the right eyes to look at a bug. If you follow vulnerabilities, you'll notice a handful of people find most of the bugs. The main advantage of open source is that the code is available for those eyes to view.
