Raid 0+1, 5 (hardware/software)
Not sure if this is the right topic area to post this question.
I am a newbie in Raid. Currently, I am running a SBS2k and all backups r on tapes. No raid.
Wondering:
How do i do a hardware raid 0 +1? How does the whole setup goes about?
Software raid. How stable is this as compared to hardware? Understand all my HDD have to be converted to Dynamic for such purpose. Any guides(Url) to assist me on such setup on a 2k server machine?
Using raid 1+0, by any chances if a HDD fails in the process, how does the system responds to it? will the system automatically fall back on the mirrored HDD and allow services to run?
Considering doing a raid5 oso, Is the setup similar to Raid 0+1?
Lastly, Is WinXP pro able to support all raid ( maybe 0, 1, 0+1, 5) functions?
Pardon me if i am asking some obvious or even stupid questions.. I am still exploring. Thanks!!

If you've got four disks, I'd go with RAID5 -- you get more space, using striping and parity-checking. I think you only lose the space in one drive for the process, rather than half of them in RAID0+1
Yes.. i totally agreed on your point. *wat am i thinking??*

There are advantages of raid 0+1.
two disks can fail at once, if it's the correct two. Overall speed may be a little higher compared with a raid 5 with a minimum of disks.

Forget to mention, I am oso running 2kserver (DIY) using IDE HDD. Will the Raid card u mentioned able to connect IDE HDD rather than SCSI? Can i still remain my HDD as basic instead of changing it to dynamic?
rindi,
Seems that using hardware raid is better. When i mention on raid 0 +1, I am actually thinking of having 4 HDDs, 2 HDD will be perform raid -0 (stripping) to increase performance while having another 2 HDD to perform raid - 1 (mirroring) to act as a backup. By any chance if my primary HDD failed, will the system automatically fall back on the 2 mirror HDD? Maybe my concept is wrong, if so, kindly pls enlighten me.
U mentioned "hot spare"... i suppose this only works if u r using raid - 5 .. am i rite?
If I am not using hardware Raid... am i rite to say that XP will only support raid 0 and 1?
Will i be able to configure raid 0+1 in XP using OS tools management function?
mightofnight ,
Wao... if the controller dies... the data will be inaccessable... can someone confirm on this? I dun wish to be in tat situation.... ;p
Lastly, I have found quite a no. of sites with good explaination of raid .. but i couldnt find any good sites with good setup instruction/guide for raid (be it hardware or software). Will anyone be able to share some good links available??
Thanks!!!
