I work for a Fortune 50, and have sr level unix experience.
In my more than a decade of using NIX, I have to tell you I love MC/SG. It’s the real deal, and the perfect example of what HA Clustering SHOULD be like. HP in their olden pre-compaq days when they actually had real R&D talen there came up with some great software, HP’s LVM (what totally inspired Linux’s), and MC/SG are 2 good examples.
I have lots of real world experience setting up Sun Cluster, IBM HACMP, and MC/SG.
MC/SG is the best by a long shot. It just WORKS, and it makes real sense to admin. Its easy to work with, extremely reliable, and a chinch to integrate your own application with.
I wish something that good was available as OpenSource on Linux. I hesiate to recommend MC/SG for Linux because it ties you into HPAQ too much because they only support it running on their OWN hardware, and we multi-vendor our intel systems with HPQ, IBM etc.. That is why our UNIX group (full of lots of MC/SG lovers) is looking at RedHat Cluster instead. It’s a shame too, because I have not seen anything that compares to the quality of HP MC/SG HA Clustering. HP is also working on integrating the “single system image” clustering features from VMS/Digital into it, and should be ready next year they tell us… it will totally uncomparable to any competition then and far above anything else on the market.
> HP’s LVM (what totally inspired Linux’s)
HP-UX LVM is entirely based on an old version of Veritas VxVM, which HP licensed from Veritas — the credit for the quality of LVM should go to Vertias and not to HP. Overall I would say HP-UX is starting to serously lag behind AIX and especially Solaris, which leads to the overall decline in the platform, I doubt that porting the TruCluster from Tru64 to HP-UX will change the picture much. HP made an extremely bad choice of betting the farm on Itanium and that will take down the entire HP midrange strategy. There is already a dark cloud hanging over Itanium and I wouldn’t be surprised if Intel drops Itanium entirely in a few years time.
..oh yeah, and let me guess HP should move to either opteron or even better SPARC, right? LOL!
So HP-UX is lagging behind Solaris… an OS which just recently got a modern File System (besides Veritas)? Jeezus…
