building on your own a large data storage ...
Hi,
~ I need to store a really large number of texts and I (could) have a number of ATA100 S.M.A.R.T.-compliant hard drives, which I would like to use to somehow build a large and safe (RAID-5?) data store ~ Now I am definitely more of a software person (at least occupationally) and this is what I have in mind: ~ * I will have to use standard (and commercially available (meaning cheap ;-))) x86-based hardware and open source software ~ * AFAIK you could maximally use 4 hard drives in such boxes ~ * heat dissipation could become a problem with so many hard drives ~ * I need a reliable and stable power supply ~ Should I got for ATA or SATA drives and why? ~ You could use firewire and/or USB cards to plug in that many harddrives. Wouldn't it be faster/better using extra ATA PCI cards? What else would it entail? How many such cards could Linux take? ~ People in the know use software based RAID. Could you give me links to these kinds of discussions? ~ What would be my weak/hotspot points in my kind of design? ~ Any suggestions of the type of boxes/racks I should use? ~ Is this more or less feasible? What am I missing here? Any other suggestions? or intelligent posts in which people have discussed these issues before? I found two in which some people have said a few right and some other questionable things: ~ comp.sys.ibm.pc.hardware.storage: "2 TB storage solution" comp.arch.storage: "Homebuilt server (NAS/SAN) vs the prefab ones? Peformance" ~ Do you know of any such "do-it-yourself" projects out there? ~ thanks lbrtchx |

Takes about 10 minutes to install and configure. I'm using it as iSCSI shared storage (pseudo-SAN) between a couple of ESX Servers and it works fine. -- Kwyj. |
