StorageWorks RAID Configuration?

» close window

The Question is:

 
Hi,
 
I am configuring a dual-redundant RA3000 controller with six 9GB drives
in a split-bus BA356.  I am setting this up as three virtual disks based on
RAID 0+1, the disk partitions being 12GB, 7GB and 6.409GB in size.
 
My question is: when setting the RAID strip size, how does one relate it to the
 known I/O sizes?  These drives are replacing a set of DSSI drives and I have
 extracted histograms of the I/O sizes from the DSSI disks.  These indicate
 that the most common I/
Os for this application are approximately 5-6 and 9-10 blocks.  So should I set
 the strip size to 32 bocks (being the smallest size that the RA3000 will
 allow) or should it be larger?

The Answer is :

 
  Please contact a Compaq StorageWorks Wizard or the Compaq Customer
  Support Center.
