Sun Clustering vs. VCS

I'm sure it has been discussed already but I could not find any
helpful thread.
I need to implement HA (Fail Over) solution between two SUN servers,
probably 2x480R + StorEdge S1 Array
I'm considering to use either

1)DiskSuite + Sun Cluster V
or
2)DiskSuite + VCS.

I'm looking for comparison , advantages and disadvantages for #1 and
#2

Thank you
C.E.

OK.  Here is my contribution....



     This is less expensive in small systems.

     BTW the latest SunCluster is version 3.1
     It is also more complex to set up with the qourum disk.
     It is a kernel level cluster implementation.
     Can Use VERY FAST system interconnects ( SCI cards / SUNFire LINK, several
     100 Megabyte/s up to 2.4 GigaBytes/s )
     This is nessesary for LARGE Oracle RealApp clusters.

     can grow to 8 nodes.



    You dont want to do that. If you go for Veritas go the whole way
    and implement  "Veritas Foundation suite HA" which
    is VCS + Veritas Volume manager.

    VCS and VVM setup can be done almost entierly with GUI's
    It is a mixed Kernel/userland implementation. Some Kernel drivers,
     but the main HA-daemon process runs as a REAL-time user proc.
    Fastest usable interconnect is Gigabit ethernet.

     Can grow to 32 nodes.

OK, rethink this architecture. The S1 will become a single point of failure.
Atleast consider the SE3310 with redundant power supplies, connections 
and controllers.
Will add only a few % to the total cost.


This seems like a disk performance insensitive solution and I would choose 
the simplest and cheapest solution, which would be #1 in this case.

I should have said that:
What is Sun Cluster V? V3.1
What version of Solaris are you going to use? Solaris 8 + DiskSuite 4.1
Number on nodes:                        2 (one in stand by)
Storage size:                                50Gb
Potential growth within 12 month: 100Gb

Thank you
C.E.

At the very minimum consider two S1 Arrays and mirror between them.
Even better would be to use a FC array like an A5200 or 3310FC.


Last I heard, using SDS with VCS (other than for the root mirror) is not
supported by Veritas.  Foundation Suite HA (VxVM+VxFS+VCS) would be best, but
you could probably get by with VxVM+VCS and use UFS for your filesystems.

What applications do you intend to cluster?

There are other Cluster products
Fujitsu Siemens PrimeCluster (Solaris & Linux)
Legato Application Availability Manager (Solaris, HPUX, AIX, Linux Windows)

I can get "disk system ds2405" (HP). Will it work?

I don't see that array listed on the VxVM 3.5MP2 HCL [1].  While it may work,
you will not have DMP (multipathing) and Veritas probably will not support your
configuration.
