CP - Dell vs HP server quotes

Without knowing the use of the two SANs, I would guess that saving the $12K is going to be worth it. Both vendors have great support, both are well known, both devices are competitive with each other. It would be good to know the intended use case, though.

In the OP, BrentMHK says he's planning to run vSphere v6, so presumably as VM storage. Which presumably turns this into an Inverted Pyramid of Doom.
The SANs aren't HPE or 3PAR SANs. They are lower tier SANs with Dell and HP branding on them. . . They may offer three 9's worth of reliability, but does that offset the switches, and the longer dependency chain?
-
And actually looking more closely at the quotes.. .
2 servers, 1 SAN, and 1 Switch.
So really this is a super cheap way to try and build the IPOD. The single switch could just die, and still be completely useless, and have no failover at all.
Making this just that much worse. At least with dual switches you could have redundancy at the switch layer, so you could fail things over in that case.
But still horrible design.

Yes, those are dangerous because they are too costly for a cheap SAN (Synology, ReadyNAS are better because they are competitive at a fraction of the cost) but really no more reliable than the cheap ones. They have the "bad redundancy" that often causes more harm than good. The support levels are good, but the hardware itself just isn't that reliable. Nothing in that price range is.

A 2-1-1. I can't recall having seen one of those in a long time.

In many cases like this the environment might be small enough that you could just remove the switch. Doesn't solve everything, but lowers the cost and removes something that could otherwise fail.

Very true, just directly connect to the storage, and set it up to failover between the servers. But at the storage need today, why purchase external storage at all?
Save the 10K-20K that each vendor is quoting and put that cost into a backup solution. Which still hasn't been discussed here on ML or there at SW.
-
What is the point of duplicating the discussion here? I understand that there were some objections to the moderation approach, but since the OP is not part of the discussion, is this anything more than an academic exercise?
-
So with regards to a backup solution (dumping the external storage) even on the lower price range from Dell.
Purchase a synology nas, even a 2 or 4 bay tiny unit could work, for maybe $1000, load it up with storage, and pay for an online storage provider to sync your backups to.
This way he'd be following the 3-2-1 rule.
And still be way under the capitol total of what either vendor has proposed, while having a complete solution!

Academic purposes are the exact reason. To explain why a proposed solution needs to be adjusted, and ways that it can be improved in all directions.
Less hardware, less complexity, more stability, lower capitol expenditure and improved results.
(Also I've invited the OP to the topic immediately after posting, he's welcome to join or not)

Ok, that makes sense.

The OP said that he wanted and appreciated the broader information so the inability to have an open professional discussion where this originated requires either that the OP be left without the information that he feels is valid (this case) or is needed for completeness (many cases.) So in the interest of a professional level discussion (meaning as professionals we have obligations to honesty, transparency, growth, education, etc.) rather than a Q&A post (the storage and virtualization arenas on SW are not Q&A only like ServerFault) the discussion has to move elsewhere. The decision to remove the open discussion for storage and Virtualization topics on SW was confirmed with SW officially, so those topic groups have nowhere to have those discussions there, and people posting on SW think that they are posting for discussion and professional guidance, which is not allowed there. So even just in the interest of letting the OPs know that we still care and are still trying to help regardless of the mod's decisions to not allow that assistance in that community. Otherwise, it looks like those of us who want to help have abandoned that community, and it's important that posters on SW know that we are still around, still trying to help them.
And in many ways, this is better. Now SW can maintain the "here is the answer to what you asked, no need to dig deeper if you don't want your boss to see" or whatever. But if the OP wants a deep discussion into what they need, rather than what they asked, they can come here. It does make it easy for them to opt in, or opt out of the deeper discussion. Sadly, it leaves casual passers-by on SW not aware that there are potential issues, but casual readers on SW are caveat emptor as far as understanding that what they are seeing is intentionally filtered "advice."

The "welcome to join" bit is actually pretty awesome. It's like 50/50 with these posts. Half of them are infuriated that we care and try to dig into their "needs" rather than just answering what they ask. But the other half are very thankful that we ask more, maybe help them think more broadly, maybe introduce ideas that they wouldn't have thought of, etc. This way, those that want to keep it shallow can stick to SW, those that want more deep can come here. So it might be a good system.

I'll just throw this out there. What about getting rid of the SANs completely and adding a 3rd host with either vSAN licensing or something like Starwind? I didn't see the post in SW and don't know if there was a business need, but I thought I'd mention this.

The full post is up top. Unless the OP jumps in here, we are pretty much exhausted on info.

That is another very valid option, just redirect the budget into a third host.

Why add a third host at all instead of just using two? If he doesn't have a third host with the SAN, there is no need for a third host without the SAN. So you could save the money, get high availability for free and have less equipment to fail. No need for the SAN, the switch or the third node.

I was thinking vSAN required 3 hosts. I guess Starwind does not?

Correct, Starwind does not, only two nodes.
-
@NetworkNerd 2 Hosts Plus a Witness VM somewhere (how vSAN or HP StorVirtual operate).
