Haven't found any 400gig sata drives, at least not for a reasonable price, we're using i think some 250s with 3ware raid cards (the tyan motherboards only have fakeraid). Man these things SCREAM One word of caution...the amd64 boot image that's latest won't complete a boot, and the older 2005.0 has broken 3ware drivers. had to install 65-bit ubuntu on a small partition and boot to that to install gentoo. and that ubuntu is NOT smp enabled, so the build went slow until I could reboot into gentoo. we're building "blade" servers...not true blad servers, as each has it's own nics and power, but you can get 10 in a 7-u rack (I think it's 7 u) Mobo recommendations (lm_sensors and acpi support) in a 19 inch rack?

Perhaps you should ask what the best price performance/watt in the cpu range? Generally it's best to figure out your needs and then calculate the cost for each step up in cpu power to meet those needs. > Complimentary ram specs? > Personally, I prefer 2-2-2 or 2-3-2.5 ram, but it's expensive and not all applications benefit. > Mobo recommendations (lm_sensors and acpi support) in a 19 inch rack? > Tyan or Super Micro tend to be better choices. > N+1 redundant power supply recommendations? > Vendors change every year. If you've got big bucks and can find someone that will sell single units - Delta.

For - Uncompressed SD video - 60 MB/s sustained. 3 to 4 IDE drives striped will do. Uncompressed HD video, up to 1080i - 270 MB/s sustained - 3 disk controllers, 3 disk arrays, 15 Krpm drives. Uncompressed HD video 1080p or 4:4:4:4 or dual-link - 360 MB/s sustained - 4 disk controllers, 4 disk arrays, 15 Krpm drives. Compressed SD video - mpeg2, 480P, DVpro - 20 MB/s sustained - 1 disk controller, 7200 rpm drives, single array. 2 streams requires Uncompressed SD bandwidth.

(Reasonable vendors that build systems and perform Gentoo > installation here in the US?) I've been running a pure 64-bit gentoo system since July/August of last year as my desktop. It had been 6 (or more) years since my last MB upgrade, and I was going for something near the top of the line so I wouldn't have to upgrade in the future. > What's the best 64 bit processor choice for performance for Gentoo? > Dual-core? > Complimentary ram specs? I went with 2 Opteron 275s and I'm quite happy with it. I'd suggest staying away from Itanium architectures for linux as it doesn't have as much developer support, from what I can tell. Also, while I am not an expert in system board design, the NUMA architecture available from AMD does appear to have fewer bottlenecks. > Mobo recommendations (lm_sensors and acpi support) in a 19 inch rack? My system is an EATX desktop, not a rack, but I'm using a Tyan board. I'll recommend Tyan with the caveat that I have limited experience. > N+1 redundant power supply recommendations? Can't say anything here, I run a single power supply. :) > 10/100/1000 Ethernet support? While I don't get to use it that much, I really appreciate Gigabit ethernet being available on my motherboard. When I'm making a backup image of a system or transferring CD/DVD images over the LAN it really pays off. > What's the friendliest high end video card for displaying video > (fast motion) that has open source drivers? Multiple displays? Do you mean pure open-source, or just drivers that will work? I think it's gonna be hard to find pure open-source drivers for a card that handles this (*please* correct me if I'm mistaken). I love my NVidia 7800GTXs. > Which Sata-2 drives give good performance and size (400 G or more)? I'll swear by my 6 Hitachi 7k500s. They have blazing performance, and they've yet to perform a single bad block relocation, despite bringing them on a road trip, and keeping them in my filthy apartment. > What's the best Raid level to run for storing, searching and > manipulating tons of video, and should I get a Gentoo friendly > controller or use software raid? Software raid in linux is fine, and you can even use some of the limpware raid (like the nv_raid on my Tyan board) with the dmraid utilities. That said, I went with hardware raid because I wanted to keep /boot on a raid array. I definitely think my areca 1160 is worth what I paid for it, and while the tools are not in portage and the module is not in mainline the support for linux is good. They provide 32 and 64 bit binaries for the command-line interface and http control interface and the kernel module is GPL'd and in the mm tree. > Finally which file system would one recommed for this video server > with the best, stable performance. If you are going to have a UPS and cleanly shutdown in the case of power failures, go with XFS. I'm a big reiser (3 and 4) fan, but I'm starting to see some of it's ragged edges, and I think XFS will probably serve you better. -- Boyd Stephen Smith Jr. [EMAIL PROTECTED] ICQ: 514984 YM/AIM: DaTwinkDaddy -- gentoo-user@gentoo.org mailing list
