585.0. "RAID 0+1 in Cluster with Dual HSZ50s" by MKOTS3::HAHN (SBU Americas Technical Support Group) Wed Jan 29 1997 12:28

A customer is implementing a NT cluster consisting of 2 AlphaServer 2100s. 
He is also using an enterprise storage array using a SW800 storage cabinet 
and 2 HSZ50 storage controllers. His plan is to implement four RAID 0+1 sets. 

His question is: From the perspective of the operating system and the 
clustering software, will the RAID sets appear as a single logical drive?

Additionally, I would like to confirm that dual HSZ50s are supported by Digital
Clusters for NT V1.0 with SP1?

Thanks,
 Dave

Will the Raid sets appear as a single logical drive?  It depends how the 
subsystem is configured.  Each Raid "Unit" appears as a target/lun device to NT.
Then, depending on the number of partitions on the device, each partition 
appears as a drive letter.

Supported Raid configurations for SP1 are the RAID 310 and 410.  The 450 is 
qualified with 1.0SP2 or 1.1.

    I think that Storage has announced support of HSZ50 on
    the existing SP1 on the WEB. Do I sell that as supported
    or not?
