Hi Everyone ,
my origional question :
I am looking for a product that will allow me to mirror two systems
on the same network in much the same way Sun's Online Disksuite works
for different disks on the same node .
Is there such a product ?
I had six responses to this question and one "me too" .
1. try looking at OpenVisions High Availability product ....tim
2. I think this is called clustering. Sun are supposed to be
releasing such a product. You *could* use rdist! :-)....David
3. You may want to inquire upon SUN if they market the clustering software
package. I know they were selling this awhile back but I don't know if
t took root in the market place.
I think it acts like DEC's clustering LAVC package. Maybe this will
give you what your looking for? ...phil
4. Certainly is - Reliable NFS from ISIS Distributed Systems. I know
email@example.com works, I think firstname.lastname@example.org and email@example.com
do as well.
It does replicated systems with automatic client failover. ....kev
5. Look into the product RNFS from the people at ISIS. Try firstname.lastname@example.org
or post in the comp.sys.isis newsgroup......Glen
6. One option is to use AFS (Andrew File System). AFS will allow you to
mirror read-only data on multiple servers. However, you probably want
a distributed file system that allows you to mirror read/write data
(don't we all?). Unfortunately, I don't know of such a product. I
think there are companies working on high availability NFS via mirrored
servers, but I wouldn't expect to see anything but vaporware and bogus
announcements for another year or so.
I did see a press release for a product called Watchdog FMS which makes
some claims in this area. I have no idea if it actually works. The
press release is attached.
A stop-gap solution might be to run a dual ported raid array on two
file servers. If server 1 dies, you boot server 2 from the same
array. This would minimize your down time, but not eliminate it.
Watchdog FMS might help you with this solution......Nate
thanks to all who replied ...
