Hi all
I am currently developing software RAID-5 solutions. I do know that there
is already a RAID driver (LDM for Windows 2000 server) present. I want to
extend some functionality and hence would like to know about pointers to
RAID filter drivers for Windows server family. Any help would be
appreciated.

Hi all
Thanks Maxim for ur answer. Based on ur answer, I would be targetting
solutions that can be built for basic disks (for eg. implemented by ftdisk).
I have scourged the osronline list and have got some documentation regarding
storage solutions for Win2k. It looks that I would have to build a parallel
volume manager that implements registeration with partmgr and converts IRPs
directed to volumes to SCSI CRBs (since i am implementing raid for SCSI
harddisks). Since volume manager is root implemented, I have to add PnP
functionality as well. This should be my basic architecture for volume
manager. Any comments?
I am currently looking for some sample codes which can get me started.
It would be a great help if some one can signal me the availability of some
sample codes regarding building of a volume manager. I also read something
abt LDM documentation from Veritas under NDA. But I am primarily looking for
solutions for basic disk type and not dynamic disks. Any info regarding
examples on the net, ddk articles etc. would be a great help for me.
Regards
Harry

Look at the Linux LVM source code.

Hi
Well…i thought of that idea but I believe that the LVM would be dependent
on the OS. I doubt that Linux LVM would have similar kind of architecture.
Are the concepts of Partition manager and mount manager similar for Linux
kernel?? I am sorry but I do not have very sound knowledge of the Linux
kernel. Some more insights on this topic would be greatly beneficial.
Thanks very much for providing some start point. I would dig into the Linux
LVM now.
Regards
Harry

Linux has nothing common with Windows about the partition and volume management, but the LDM is the on-disk layout standard which is cross-OS.
