IVM

Pete Randall — Tue, 07 Oct 2008 09:38:16 GMT

I'm trying to budget for a new Itanium server for next year. I'm going to want to virtualize my production and development environments on this machine so I was thinking that IVM would be the perfect solution.

So, first off, is IVM the perfect solution or would some other (VPars?) virtualization method be better.

Second, what the heck does one have to order to get IVM? If I look so software.hp.com, the virtualization link says:

"The products for this category are coming soon. Please check back at a later time. "

Not terribley helpful. I did find some sort of trial for IVM (can't find it again, though), but no product number and little further info on pricing or the like.

Can anyone shed any light on which direction I should be headed and how I'm supposed to get there?

Pete,

The acronym IVM is for an IBM product (Integrated Virtualization Manager) - we try not to use it if we can help it. Generally HPVM or Integrity VMs is what we try to say!

Whether HPVM is right for your environment is down the the load profile of the environment you want to virtualize... heavy IO and CPU loads? Probably best to look at vPars... light IO load and spikey CPU loads - might suit HPVMs well... as usual the answer is "it depends". Can you share some more data with us on what this is for/what it is replacing?

With regards to purchase, its pretty easy now, just order the VSE Operating Environment and you will get HPVMs/vPars into the bundle (remembering of course that you can only use vPars on cell based systems.)

The VSE OE also bundles in everything else you need for VSE (gWLM, Capacity Advisor, Virtualization Manager). For a whistle-stop tour have a look at this webinar here:

My apologies for the mis-use of the acronym. I had no idea!

With regard to our environment, it varies. Day to day we are an online, real-time DB - neither I/O nor processor intensive. Four times a year, we run a huge process which ends up updating virtually every record in the database after doing some heavy duty number crunching on performance data.

We currently run both production and development in separate VPars on an rp7410. I've never been truly happy with VPars, though, and the little bit I've been able to gather about HPVM sounded like a better solution - more flexible, etc., etc.

When my vendor came back with a $20,000 quote on the T2786AC VSE Suite product, it virtually blew my proposal clean out of the water. I can no longer come anywhere near cost justifying the new hardware/software environment. The only hope I now have of getting this approved is to beg and that rarely works.

I thought VSE was a completely separate product - was I mistaken?

VSE is one of the "NEW" OEs. HP has recently completely revamped their OE lineup.

Pete,

>> Four times a year, we run a huge process which ends up updating virtually every record in the database after doing some heavy duty number crunching on performance data

With that in mind I'd be tempted to go vPars again, although that puts you on a rx7640 as a minimum. However as you're replacing a rp7410, if you want like-for-like OLTP performance a rx6600 with 2 sockets/4 cores of CPU (out of a possible 4 scoket/8cores) would more than match the performance of the old war horse.

So the question is, do you risk the non vPar platform which you'll have to run Integrity VMs in (which might get perf constrained during your update process), or do you cost for a more expensive rx7640 which will do vPars and give you a "known" solution. My advice would be to request a PoC service with the vendor and go through an update in a HPVM to judge it for real.

I hope you've costed in the savings you make from transferring your OS licenses from the rp7410 to the new platform - that can save you a bunch of money. (If your rp7410s already have the Enterprise OE plus vPars you might be able to transtition straight to the VSE OE)

As for VSE - well you don't have to buy all that if you don't want to or budgets don't allow, but I have to say its the future - this stuff really rocks when deployed right.

You could just transfer your existing licenses and purchase HPVM licenses only (T2767BC) - not sure about costs in US$, but in GBPÂ£ its approx Â£1000 for a license and Â£1000 for 3 years 24x7 support per-core, so 4 cores = Â£8000 at list price (thats less than $16,000 dollars before discounts)

The confusion over products is probably down to the new Operating Environments - one of them bundles in all the VSE stuff - see more here:

One more point - don't skimp on memory on an Integrity server - the IA64 architectire is generally more memory hungry than PA-RISC, so I usually look for 1.5x - 2.0x the memory (i.e. if you have 16GB now, go with 24-32GB in an Integrity system)

The good news there is that (although still expensive compared to PC memory), Integrity memory isn't as expensive as it used to be. Again you'll find the rx6600 memory to be cheaper than the rx7640 memory.

My experience.

We run 3 rx6600 8way 64GB RAM supporting prod and non-prod oracle environments in 21 vGuests backed by 2 EVA 4000s. and a 4th server for DRP.

I am very happy !!

Creation and deployment is a breeze.

We have had NO performance issues as of yet. I would lable our workload is medium. Certainly if you have a single workload that would consume all the physical resources then vm is not right for u.

As mentioned the new release of 11.31 has a release that replaces the EOE that includes all the IVM software required.

Also as mentioned, RAM RAM RAM.

Re: IVM

Pete Randall — Tue, 07 Oct 2008 12:50:40 GMT

I think the rx7640 is out of our league so that would eliminate VPars. We've been looking at a rx4640 with 4 cores. The only major difference I can see between the 4640 and the 6600 is that the 6600 has the zx2 chipset. Is that going to make a huge difference?

The biggest of our number crunchers doesn't even run on-site since our R&D machine simply can't handle it. It's been run at the University on a Linux box with a 3GHz Opteron processor with 64Gb of memory. Can we expect the rx4640 or rx6600 with 32Gb of memory to match the current performance that we've been seeing?

Re: IVM

Tim Nelson — Tue, 07 Oct 2008 13:18:09 GMT

That would be a touch call Pete.

I guess if you think about it this way it may help you to decide, at least on using vPars or IVM.

vPar vs IVM:

IVM
resources are shared granularly
CPU, MEM, IO are all shared

vPar
resources assigned by hba (or entire entitity)

If you are looking to better share and use all your resources on a single physical server then IVM is the way to go.

If you wish to share some resource but keep those resources isolated the vPars are the way to go.

My issues in the past with vPar is that I ran out of HBAs. Had to have at least an rp7xxx server to hold all the hbas and/or CPUs.

With IVM you are only limited by RAM ( each HPUX install needs at least 1GB ( or there about ) and then add on the app reqs. So a 4 GB server could only support 2 small guests. An 8GB more smaller ones or less bigger ones..

The reason I went with the rx6600 was that it was the largest small server HP had. The CPU performance was equiv to an rx7xxx and ram max was 128GB. ( here was the great part) The RAM in the rx6600 was 1/2 the cost of the same RAM in a rx7xxx ( about $500/gb vs $1000/gb.. Maint was also 1/2 the cost.

If you think that 8 CPUS are not enough then you must go rx7xxx or bigger.

Duncan Edmonstone — Tue, 07 Oct 2008 13:27:35 GMT

Pete,

Unless you are looking at 2nd user equipment, I'm not sure why you would consider the rx4640 - it's end of sale, doesn't support the latest Montvale processors and I don't think its actually cheaper than a rx6600 anyway.

The rx6600 zx2 chipset offers considerably more bandwidth and faster memory.

It's also likely to go end of support about 3 years sooner than the rx6600 as well.

When you say number crunchers - can you characterise that? Are we talking a lot of floating point arithmetic, or just integer? or Something else entirely?

HTH

Duncan

Re: IVM

Pete Randall — Tue, 07 Oct 2008 13:52:04 GMT

Yes, the rx4640 was what we call "remarketed". I assume that's the same as "2nd user". I told the vendor that I wanted the latest chipset and longest support life, but didn't follow up to make sure that's what I was getting. Remind me to shoot myself later.

As far as characterizing the number crunching, I'm trying to get further details. All I can say at the moment is that it's a Fortran program which calculates "genetic evaluations for type traits", whatever that may be. I'll post any further info as soon as I get it.

If I had the choice I would take a zx2000 system or at least a zx2.

Some nice features:

Since the rx4640 is no longer listed among the entry levels, you will get a second hand machine only.

We have used IVM in Oracle DB devel/test environments for 2 years (starting from 1.2). I personally like the rx2660 version - IVM host OS local disks, ~3-4 IVM Guest OS on local disks/or SAN and DB on SAN; 32GB is proportional to CPU power. But in your case i agree with previous writers that rx6600 sounds reasonable with enough flexibility to add ram/cpu.

Pete Randall — Fri, 10 Oct 2008 11:31:31 GMT

Have faith guys - I haven't forgotten this thread nor your efforts. I'm just waiting on further information.

I do have one more question, though. Why is it so damn hard to find out what a HP-UX server costs? Why can't HP have a site like Dell's, where you can just pick out the things you want on your server and it will show you list prices? Spending days working with vendors only to find that they're quoting you something that isn't what you want sucks. Meanwhile the boss is breathing down my neck because this was supposed to be all wrapped up last Monday!

Arrrgggghh!

I finally found a website where I can "configure and price" and after I go through the whole specification process, it says "contact HP" in every last price slot. Damn.

The enterprize configurator has been on the HP site for years. They moved it recently to a new site.
