Veritas Server Quick start Veritas Cluster Server software (VCS) Veritas SANPoint Foundation Suite HA (using Cluster File System and Cluster Volume Manager) - priced. 2. Sun Cluster Software - priced and is available cheaper via ScholarPac for educational institutions. I am checking into this. 3. Legato Cluster products 4. Through action scripts 5. One response doubts that NFS will not work. He says: "The thing is, when NFS server goes down client needs to re-mount the partitions" Detailed: I have attached responses that were some what detailed than above. Sundar Original message: --------------------------- I am looking for 3rd party software (freeware, if possible) solution under SOLARIS. Here is our problem. We would like to have a system with no single point failure primarily for NFS services. We are thinking about two Dual CPU 64-bit Ultrasparc processor systems with heartbeat approach and common storage. Solutions from Sun Microsystems are way too expensive for us. I would like to know if there are any 3 party companies offering a "Software" on SOLARIS to check heartbeat of machines and to do the switch over automatically if one of the two systems should fail. Any web links will be helpful, especially if there are any freeware packages. I can find many useful sites for LINUX. Unfortunately, I need ones for SOLARIS. Any experience on the above subject is welcome. Thanks in advance.

Apparently it's now available and much more reasonably priced (but only if you're doing it under ScholarPac -- and I would think that iupui.edu would already have a ScholarPac program or would qualify for one). Alternately, the Sun Fire V880 systems have a great deal of redundancy built in (plus you can impletement IP multipathing and disk multipathing for not too much extra). While there are still a few single points of failure, it greatly minimizes it while greatly minimizing the effort needed to manage the systems. Just some ideas based on our experience in trying to solve what appear to be similar problems.

It is not cheap, but it works well and is rock solid. I am employing Clustered Filesystem and Clustered Volume Manager (CFS and CVM), which allow you to mount the filesystems on all nodes in the cluster at the same time from the SAN storage system. This is very useful to reduce fail-over time. I can let you know all about it, if you want and give you an unofficial reference. Let me know and I'll give you my contact info. -john Paramasivam, Meenakshisundaram wrote: > I am looking for 3rd party software (freeware, if possible) solution under > SOLARIS.

Cluster concepts - multiple hosts, checking to make sure each other is alive. - share disk of some sort - one host goes bye-bye, the other assumes its job (virtual IP address moves over) there are some very serious caveats if you want to grow your own cluster. First and fore-most is reliability. if you want to do this for an NFS server, you will need both machines able to talk to the same disks. (this too costs money) when one machine goes down, the other will kick off a series of scripts to startup a virtual IP and then bind the NFS server to that virtual IP. routers/switches will need to have their arp caches flushed, since network traffic is done to the MAC, not the IP, and arp will associate MAC to IP. in theory it could be done by scripts in the solaris world. I think that unless you have decided that Linux will not enter your shop, you may want to investigate the feasibility of Linux clustering (I am not very familiar with this) it will likely be cheaper. But in any event there will have to be some sort of outlay of Cash (either in shared disk {SAN, T3, A5x00, etc}, or proper clustering software) -- John Timon Desk: 519 667 7187 Cell: 519 852 0042 Email: john.timon@labatt.com Pager: 519 430 1826 "I feel sorry for people who don't drink.

It has some binaries but is based around 'action scripts'. With a peek at these scripts it should be possible to script the whole thing.
