Stop here.

You can build a complete brand new AMD dedicated test machine with parts from Newegg for $238 USD, sans KB/mouse/monitor, which you already have. Boot it up then run it headless, use a KVM switch, etc. http://www.newegg.com/Product/Product.aspx?Item=N82E16813186189 http://www.newegg.com/Product/Product.aspx?Item=N82E16820148262 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103888 http://www.newegg.com/Product/Product.aspx?Item=N82E16822136771 http://www.newegg.com/Product/Product.aspx?Item=N82E16827106289 http://www.newegg.com/Product/Product.aspx?Item=N82E16811121118 If ~$250 stretches the wallet of your employer, it's time for a new job. > 2.

Get yourself an Adaptec 8 port PCIe x8 RAID card kit for $250: http://www.newegg.com/Product/Product.aspx?Item=N82E16816103231 The Seagate ST3000DM001 is certified. It can't do RAID5 so you'll use RAID10, giving you 6TB of raw capacity, but much better write performance than RAID5. You can add 4 more of these drives, doubling capacity to 12TB. Comes with all cables, manuals, etc. Anyone who has tried to boot a server after the BIOS configured boot drive that is mdraid mirrored knows why $250 is far more than worth the money. A drive failure with a RAID card doesn't screw up your boot order. It just works. > In next few months it is expected that size of files on dedicated > servers will grow and it case that really happen I'd like to be able to > expand this system. See above. > And, of course, thanks for your time and valuable advices, Stan, I've read > some of your previous posts on this list and know you're storage guru. You're welcome. And thank you. ;) Recommending the above Adaptec card is the best advice you'll get. It'll make your life much easier, with better performance to boot. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
