If I were to decide my current setup is too problem beset to continue
using it, is there a guide or some good advice I might employ to scrap
it out and build something newer and better in the old roomy midtower?
I don''t mean the hardware part, although I no doubt will need advice
right through that part too, but here I''m asking about maintaining the
data on 3 mirrored pools.
I have: rpool @ 2 WD 500GB (old fashioned IDE)
pool2 @ 2 WD 500GB sata
pool3 @ 2 WD 750GB sata
A total of something like 1.7 tb maybe 35% full of data
I''m a bit worried about whether with modern hardware the IDE drives
will even have a hookup. If it does, can I just hook the two rpool
discs up to two of them and expect it to boot OK?
I expect to make sure I have a goodly number of sata connections even
if it means extra cards, but again, can just hook the other mirrored
discs up and expect them to just work.
Not likely is my guess, so what about some kind of brief outline to
use for a plan of attack?
Would I expect to need to reinstall for starters?

It''s also still very easy to find PCIe cards with IDE ports (some have SATA as well). Again, you will need to check the fine print to make sure that they support booting off IDE. Assuming that you aren''t currently using any hardware RAID, then there should be no problems accessing any of your existing pools from a new motherboard. Booting off your IDE rpool just relies on BIOS support for IDE booting (which you will need to verify).>I expect to make sure I have a goodly number of sata connections even >if it means extra cards, but again, can just hook the other mirrored >discs up and expect them to just work.Finding PCIe x1 cards with more than 2 SATA ports is difficult so you might want to make sure that either your chosen motherboard has lots of PCIe slots or has some wider slots. If you plan on using on-board video and re-using the x16 slot for something else, you should verify that the BIOS will let you do that - I''ve got several (admittedly old) systems where the x16 slot must either be empty or have a video card to work. If you are concerned about reliability, you might like to look at motherboard and CPU combinations that support ECC RAM. I believe all Asus AMD boards now support ECC and some Gigabyte boards do (though identifying them can be tricky).

Maybe at search.gmane.org It would be too lucky to expect someone has a list of some good (up to date) setups a home NAS fellow could be inspired by eh? I know there is a hardware compat list... but last time I looked it was not being kept up to date. This is getting a little far afield but: Another thought someone else had in a similar thread was to host Osol in a Virtual Machine. I''ve thought about that and kind of like the idea. Here is why: My main use of computers has been a hobby... I piddled around with the various free solaris OSs going back quite a few years and with linux for much longer. Now (since retirement) I''ve become sort of a semi-professional video editor and Graphics editor/creator. Nearly all my tools rely on windows OS such as the Adobe suites, or the Sony (Vegas) tools and etc. That is what I need a NAS for mainly... those kind of files will soon fill up even large disks. So how would I go about that kind of switch? Lets say I built up a dual quad something with i7 920 or such and lots of SATA connections or extra sata cards and running windows 7 to be both my video editing machine and my NAS in one go. Would there be any way to get the VM hosted opensolaris OS to use the current discs and not have to move all the data some how? Or really any ideas at all about how to take a run at something like that. Seems like it might require two machines at some point for a one time effort to export from one and import from the other... I''d sooner not have to do it that way if possible.>> Would I expect to need to reinstall for starters? > > With care, nothing.Ahh good news... thank you sir.

E.g. a 16x card in a 1x slot. Doing so with probably require the use a a Dremel tool or soldering iron to cut or melt off the back of a PCIe slot. An 8 port SATA PCIe 4x card could be used in a 1x slot using this technique (performance limited to 1x).

These models support ECC, don''t change as often, and are supported longer, which are good characteristics for a build it yourself server/workstation. -------------- next part -------------- An HTML attachment was scrubbed...
