Here is the summary to the following question:
Hi folks!
> Can I implement TruCluster Available Server Software v1.5 without having
> a Memory Channel(hardware piece)? (the cluster will be two 8200s sharing
> an HSZ50 RAID), (and I'm using DU 4.0E.)
>
------------------------------------------------------------
Answers:
------------------------------------------------------------
Yes, available server does not use Memory Channel. Production Server
needs
memory Channel, and Trucluster Server (for TRu64 V5.x).
Be careful with the patches!
Regards,
Claudio.

release notes:

hardware config:
http://www.tru64unix.compaq.com/faqs/publications/cluster_doc/cluster_15/cluster_15/TCR_HWCFG/TOC.HTM
the hardware config states:
The concept of using an available server environment (ASE) to provide
highly available services and storage. An Available Server configuration
consists of one ASE. A Production Server configuration must contain one
ASE, and may contain up to four ASEs. A MEMORY CHANNEL
configuration contains no ASEs.
which means that ASE does not require MC - it is a failover mechanism
that uses the SCSI bus and network to coordinate efforts, if I'm not
mistaken.
Here is the next quote that supports this:
TruCluster Production Server Software--The TruCluster Production Server
Software (formerly known as TruCluster Software) combines the
capabilities of the TruCluster Available Server Software and TruCluster
MEMORY CHANNEL Software to provide a high-performance, highly
available, and scalable operating environment
------------------------------------------------------------
Yes,
I have done it more than 10 times.
I think you might need the MCA stuff in V5.0 though.

Yes, Available server clustering doesn't require memory channel. The
production server and trucluster 5.0 do require memory channel.
