service guard and hacmp comparision

Shivkumar — Mon, 08 Aug 2005 23:30:06 GMT

Dear Sirs,

I am working on reccomending clustering solutions but unfortunately have not worked on any of them :-).

We are running pSeries AIX and HPUX 11i unix.
Can someone compare HACMP and MC/Service Guard.

Thanks in advance,
Shiv

Hi shiv

Pls refer the document below. This contains a comparison table from page 6 onwards

Question you are asking is to compare two religions. If you ask it here, you will hear the opinions of pro-hp biased people. If there exists a itrc like place for aix, and you happen to ask it there, you will hear the opinions of pro-aix biased users. Unless you get the information from both camps and do the deductions yourself, it will not be objective.

One thing to keep in mind: IBM lined up its guns behind linux. I am personally quite suspicious of their commitment to AIX and improving the HACMP or any other product.

Shiv,

Your are asking whether to choose HP-UX (PA-RISC or Itanium- or AIX as hardware.

Of course everybody will answer here to choose HP-UX and so do I. The support of IBM is not that good and they don't have an ITRC forum.

best regards,
Kurt

Hi shiv

The points made by Mel and Kurt are correct.. In this forum it is touch to get any pro-IBM comments..The document which I attached is also a pro-HP-UX one...:)

Hi Shiv

HACMP and MC/Service Guard serve the same purpose. You have to compare them Commercially. Installed base of MC/Service Guard is higher than HACMP worldwide.

I think when looking at ServiceGuard, you may also want to look at MetroCluster and Continental Clusters which are related. Also, HP is supposed to release updates to SG to add support for the Veritas Cluster File System this month, so some of the older comparison may no longer be fully accurate. Please remember that a highly available solution is more than just the SG software. It is only one element of a plan that must be designed, developed, and implemented. OpenView Operations and Performance Agents can also be a key in monitoring capacity and performance, so that proactive steps can be taken if needed that deal with problems that are unrelated to hardware failures, but can affect application availability. You can be just as dead from running out of disk capacity as from a hardware failure, so don't think that buying SG or HACMP is equal to the total solution. More failure are due to people and process breakdowns than hardware, so make sure you address them too.

I work along side a group of sa's who administer aix boxes and listen all day long to their complaints about how IBM support really bites and their longings to be back with HP systems. If that helps at all...
