@Dashrender Yep, in that configuration we have 24 TB of SSD.
If we added an additional 32TB of HDD (given the fact you would already have 24TB of SSD), it would add around $13,000 to the total cost provided before
So rolling that all together (though we have no idea what it looks like in configuration) we have
4 units (dual xeon 2650, 256 GB RAM, 6 TB SSD, 8 TB HDD, 5 yr warranty/support) = $89,600Is that right?
So we have better processors, double the RAM and of the 56 TB of storage 30% more of it is SSD. right?

Scott didn't mention the RAID controller in his Dells, what kind of RAID are in your boxes? how about the warranty, what are the details?

No RAID with hyperconverged players. Not that there couldn't be, but no one uses one. Since everyone has to have RAIN anyway at a higher layer, having a RAID controller doesn't add any value. So none in the Scale, VSAN, Starwind or IPOD examples. Not just no RAID controller, no RAID at all. HTBase is the same in that regard.

for the uninitiated, you just blew my mind a little.

@Dashrender I was SO confused the first few times I ran into RAIN being discussed.

@John-Nicholson and I have been talking about the death of RAID for years. RAID pretty much exists as a vestige for very small environments that still see their infrastructure in terms of "a single server" and not as clusters and clouds. Once you get beyond the "each node handles its own storage" point (which only applies to one or possibly two host clusters) RAID has no value. Gluster, CEPH, and anything perceived as "cloud storage" and anything like VSAN, Starwind or hyperconvergence are all RAID-less. We've long been in the post-RAID world, RAID remains almost solely for the smallest SMBs.

We were on the cusp of being post-RAID at the Wall St. shop I was in by 2006. We were evaluating non-RAID clustering but it just wasn't there in performance terms at the time. We were able to use RAID to go faster for our big performance needs, but that was a long time ago. Luster was a major push to change that.
-
@Dashrender Yep, thats right!

What are alternatives to Lustre today? Gluster?

@dafyre HTFS from HTBase too!

Is the HTFS free or open source?
If it's not free, how is it priced -- per host, per TB... etc?

And can it be used independently? What interfaces are available for it?
-
@dafyre Its not free or open source right now. Its charged on a host/node base
Yep, it can be used independently from our hyperconverged solution

Thanks for the heads up!
Can you share list pricing per host?

A cost difference of $67,594 is pretty significant for any SMB.
Because you picked something I would buy, well, not me because I would run out of space first on it, not an SMB. Dell still sells Compellent storage. An SCv2020, same amount of disks, with support, is $30K on Fibre Channel. Why not quote PURE SANs while we are at it, stacked to the gills with the fastest SSDs we can find?
Cherry picking storage is always gonna make hyperconvergence look good. You need to review your workload to determine if that's gonna be the right path. Most SMBs workload only needs cheap and deep storage because they are all digital packrats and very little compute. Most SMBs workload would be better ran in cloud services. So really, it's not about cost study for local servers, it's about if it's better to host outside and get a giant NAS for those local files which people can't seem to get rid of.

Not cherry picked. Literally the closest competitor with their most aligned product. It's a product that is significantly below the standard of the HC solution and the minimum we could possibly consider to be competition. Going to Pure is ridiculous because it is so much more and not comparable. Compellent is "sold" but is lower end than is seriously consideration in apples to apples and as it is now at risk for support, it's not considered a viable competitor anyway. Cherry picking is the opposite of what was done here, this is as not cherry picked as we can get.
Find 3PAR or HDS pricing for hybrid storage if you want other options in a reasonable range. Anything "less" is cherry picking to lower the price while changing the goals.

I thought you worked for a serious hosting company. That's entry level SMB storage. VNXe is super low end highly reliable storage.
-
And here shows the constant issue with finding a solution.
I think Scott is on the right path, trying to make the apples to apples comparison. I don't know anything personally about Compellent, so I'm not sure why Scott doesn't like it - he explained some, but not enough to overcome my lack of knowledge.

Compellent isn't bad, or wasn't. But it is a known "dead end", it's part of the Dell storage family that EMC is replacing. Right now, the market is considering any Compellent sale to be "dumping of old stock." The VNXe is what Dell bought to be the Compellent replacement. I don't know if Compellent has a product up to par with the VNXe, but they had good stuff. But the prices are not that much cheaper, and if they are in any way not on par with the VNXe, then they are "cutting corners" even more to make SAN look viable where it clearly is not.
As it is, the VNXe is "cutting corners" on speed, reliability and flexibility compared to the alternative solution to make the IPOD / SAN approach look better than we should, it's just what I feel is the "best" comparison as it's "good enough" to be a viable SAN while having specs that most closely match the other specs and is from the market leader. But even EMC only sells the VNXe as a five nines (e.g. not high availability) and entry level product, so it is not actually on toe to toe level with the six nines hyperconverged product that we are comparing against. We get five nines from a normal server, so the VNXe doesn't have the "order of magnitude" improvement that you should be getting from an HA solution.
