2038.0. "RAID x LSM x Sybase" by VAXSPO::SWM_WANDER () Wed Apr 30 1997 14:17

    Hi,
    
    We'll have to install ASE in a customer with the following
    configuration:
    
    2 x 2100 5/300 with 2 CPU's each and 1GB Memory running Digital Unix
    V4.0A with 1 x SW300 with 43GB of disk using RAID 5/LSM/ADVFS.
    Will be created 2 services: One Disk Service that will be used by a
    COBOL Database and one DRD that will be used by SYBASE Database.
    Questions:
    
    	- Does anyone using Sybase V11.02 with ASE ? Or does someone knows
    something about if it works or not with ASE?
    	- Is DRD the best option to configure a service for Sybase? As far
    as I know, Sybase wants Raw devices.
    	
    	Any help are welcomed
    
    	Tanks

    Hi Wander,
    
    Is SYBASE working withe ASE ?
    
    Yes, there is a lot of notes here about it.
    
    Is DRD service the best way to implement SYSBASE (raw device)
    
    NO, NO, NO!   DRD is a service provided by TRUCLUSTER software and NOT
    by ASE software. Nowadays, only ORACLE PARALLEL SERVER (OPS) and later
    INFORMIX PARALLEL SERVER (XPS) are able to use DRD. DRD is using Memory
    Channel hardware to give access to the raw disk from ALL THE MEMBERS
    of the cluster. SYBASE is not (yet) supporting DRD.
    
    But, ASE (thus without Memory Channel / DRD ) can provide access to RAW
    devices that SYBASE likes to use.
    
    Hope it is clear ,
    
    Manu.
2038.2Thanks...VAXSPO::SWM_WANDERFri May 02 1997 11:067
    Thanks Manu and sorry for my wrong notion about DRD. Actually the
    customer will not have TruCluster, just ASE.
    I'll try Sybase Conference about the questions related to it.
    Thanks again.
