Comment Re:Yeah, like maybe the other CMU (Score 1) 699

I just recently graduated from the electrical and computer engineering program at Carnegie Mellon. The IT policy was pretty solid, open to all platforms, no headaches. Data integrity and personal privacy are held very highly. Student data stored on CMU servers may not be access unless there's an emergency, or if there's a valid warrant.

Getting caught by the RIAA/MPAA/BSA with copyright violation gets you 45 days loss of connectivity on that MAC address, but there's a solid intra-CMU file sharing network.

Plenty of bandwidth available to students (average 1-3MB/sec up and down -- yes, megabyte). Limited to rolling average of 2GB up/down a day over 5 days for wired connections. 750MB for wireless.

More general information can be found here: http://www.cmu.edu/policies/documents/Computing.htm

Because it could be really, really cool. As an engineer I like "hard" problems, and when I find a project interesting I go after it -- regardless of how "flashy" it is to the general public.

I think in Google's case, this is certainly true if you examine how much work has gone into their infrastructure (and how many research papers have been written on those topics).

Data Storage

Submission + - RAID vs. JBOD vs. Standard HDD's

Ravengbc writes: Hey everyone, I am in the process of planning and buying some hardware to build a media center/media server. While there are still quite a few things on it that I haven't decided on, such as motherboard/processor, and windows xp vs. Linux, right now my debate is on storage. I'm wanting to have as much storage as possible. At first I was thinking about just putting in a bunch hdd's and leaving it at that. Then I started thinking about doing a RAID array, looking at RAID 5. However, some of the stuff I was initially told about RAID 5, I am now learning to be not true. Such as, RAID 5 drives are limited to the size of the smallest drive in the array. And the way things are looking, even if I gradually replace all of the drives with larger ones, the array will still read the original size. For example, say I have 3x500gb drives in RAID 5 and over time replace all of them with 1TB drives. Instead of reading one big 3tb drive, it will still read 1.5tb. Is this true? I also considered using JBOD simply because I can use different size hdd's and have them all appear to be one large one, but there is no redundancy with this, which has me leaning away from it. If y'all were building a system for this purpose, how many drives and what size drives would y'all use and would y'all do some form of RAID or what? Also, if anyone has suggestions on motherboard/cpu thoughts, I'm open to suggestions. Thanks guys.
