 Thread : Segment Size of SAN storage and dynamic disk

More Information

Dear all,

I have a very strange problem on my server.
I am using a IBM DS4300 SAN storage, with three RAID 5 arrays on it.
Strange that the last IT guy in my company set them all to the same server, and create a Windows DYNAMIC DISK, SPANNED VOLUME with this three Hardware RAID 5 arrays!!!! OMG!!

The problem is two of the RAID 5 is using 64KB as segment size and the third one is using 128KB segment size, I suspect that this is causing performance issue on my backup to a LTO tape which is also 64KB segment size.

I know that the DS4300 can change the segment size of the array online while user can still access data on it, but will it corrupt my dynamic spanned volume on windows?

And now I am stuck......... I hate the guy who set this up. :(
