For the record, scale starts at 3 nodes.
No less.

Now the suggestion has already been made that we need a refresh and it's ready been mentioned SAN! from my days on here and SW I know with only 20-30 VM's and 3-4 Hosts we most probably don't need a SAN, but we do need HA, as the SQL/Dynamics/Citrix need to be running 100% during office hours as down time (even 10minutes) could loss us a £50K order.
Since a SAN undermines HA (doesn't make it impossible, just works against it) ask people why they are even putting a SAN on the table. Force them to tell you where the idea came from (hint: answer is always a sales guy) because, and you should point this out before they answer, the SAN introduces these problems:
- Complexity. More moving parts, more dependencies.
- SIngle Point of Failure without mitigation.
- Risk that the SAN will be dual controller and worse than a normal server (unless you spend a fortune)
- Expensive. It's an entire device without a purpose, so every penny is lost money
- Risk. It adds risk, working against your HA.
- Undermines Existing HA. Things like DC HA are totally broken by introducing a SAN.
- Slow. A SAN has extra bottlenecks and overhead, it can't ever be quite as fast as local storage.
So costly, slow and risky. Establish that these are the natural artifacts of a SAN. Then ask them that given these architectural facts, what were the benefits that they were thinking the extra cost and risk were going to be worth.

No less.
The smallest is one pure storage and two mixed compute/storage nodes. Compute doesn't need to be on every node necessarily.

You can also use EMC ScaleIO for free with your own hardware if you use the community for support https://www.emc.com/products-solutions/trial-software-download/scaleio.htm (or you can buy the software or pre-configured dell servers with it).

Number of VMs is not a factor in choosing a SAN. But number of host nodes is. And at three or fewer, SAN is literally off the table, there is no possible use case for it. At four it's a million to one that it could make sense, but it could but never where HA is even remotely important. So from the most basic SAN factors, SAN isn't even a remote possibility here. No matter what your goals are otherwise, SAN can't meet your needs. It's super simple in this case because of the HA need, even at four nodes SAN isn't viable. No way to implement it without totally screwing the company financially.

For commercial use, too? How did I not know that they had opened this up?

Thanks Sam. Will look over your article on Monday try and get ready when we have the talks soon lol.

Yes, the EULA has no restrictions on that. Their marketing terms of course try to convey you should " When you are ready to purchase a ScaleIO software license for full production use and maintenance, contact a Sales Associate" but the EULA has nothing requiring it.

Just checked, it says you have to purchase a license to use it. This is the trial only and is only for testing.

Oh okay! You've been through the EULA? That's awesome that they quietly left that out.

There is a video coming from MangoCon 2016 very soon that covers this as well.

Maybe print out the SAN article and this one as well for them.

And print this out and have it ready in the "tech pack" for them. This covers why those SAN sales people are out to get them.

As Scott said, using a dedicated SAN for this kind of environment is currently the leading cause of cancer in the United States. You could use some type of VSAN to provide shared storage between the servers. VSAN/HP VSA/StarWind will do the trick if you decide to repurpose existing hardware. If you decide to get new hardware, then Scale or StarWind's HCA are your friends.
-
Do you have a fancy PDF brochure and a nice PPT presentation stating that your solution is high performance and wonderful?
People would rather pay more for a riskier solution if how it is packaged is appealing to them.
Education is 1 thing and works for some leadership types but others just want a flat quick guarantee of "Will this be the right thing, sell it to me" and you don't have much time to do that.
-
@ardeyn Thank you very much for mentioning StarWind.
StarWind HCA should fit your needs perfectly. It is based on Dell hardware and will provide you VMs with pure 100% synchronous HA. This solution is also fully supported by a single vendor and comes to your site preconfigured.
We are also Dell OEM partner, thus less expensive than our competitors. -

This isn't true. Don't get yourself intro trouble with misuse! You can't use it for production and you have to let EMC know you evaluate with a prod use in mind. That's EVERYTHING but free... IMHO.

You are reading that incorrectly. That's just definitions, not the terms. Our EMC rep already confirmed it to us.

Look at 3 A... "License Grant. Subject to Customer's compliance with this Agreement, EMC grants to Customer a non-exclusive, world-wide, royalty free, full-paid, terminable, and nontransferable license, under EMC’s copyrights, to Use: (i) the Software for the Customer's Internal Business Purposes;"
Combine that with Definition E...
