DataCore Hyperconverged VSAN for vSphere – Could things. Get. Any. Sloooower?

You know, all these VMware vSAN alternatives sometimes look to us as a bunch of bands doing nothing but playing Nirvana covers. Oh, come on! Nirvana rocked, you guys just don’t! But, let’s face it, VMware vSAN doesn’t rock either… That’s why we are unstoppably looking for an alternative. Today, we take a closer look at DataCore Hyperconverged Virtual SAN for vSphere. Can it do better than any other vSAN-like that we reviewed before?

HOW NOT TO PERFORM: TESTING HPE StoreVirtual Storage VSA (Very Slow Appliance) on 2 PHYSICAL NODES

Justice hits everyone. And in this article, we’ll bring HPE StoreVirtual Storage VSA to trial. Two physical nodes setup. Storage comprised exclusively of NVMe drives to give our suspect a chance to show all he’s good for. So can StoreVirtual VSA performance scale with the addition of new VMs or goes to jail? We’re going to find this out right now.

Does Number of disk stripes per object have something to do with VMware vSAN performance on the mixed NVMe-SSD underlying storage?

We all know how slow VMware vSAN is. But, hey, can it be due to the Number of disk stripes per object default settings? Let’s see what this etcr can do once tuned “right”!

BALALAIKAS ASIDE! Testing StarWind Virtual SAN performance on 2 physical nodes

So while we were testing VMware vSAN on a 2-node cluster powered with NVMes, the Russian bear slammed in screaming (imagine typical Russian mafia accent) “Dnacv, hold my vodka and give me two balalaikas servers and I show you how to scale from mother Russia to America”. We thought we don’t wanna mess with drunken bears so here we are. Testing StarWind Virtual SAN for Hyper-V. Yes, there is a version for Linux, (seems that these guys just scale their solution instead of performance?) on a two-node VMware ESXi cluster powered with NVMe drives. Wait what?! VSAN for Hyper-V on top of ESXi? Yes, we have two ESXi hosts with one StarWind VM per each and the VMs are working on top of Windows Server 2016, providing the highly available storage (NTFS, it’s Windows baby) further as a VMFS datastore to ESXi…This is madness…NO! THIS IS STARWIND!!

Why is VMware vSAN that slow? Trying out your ideas to squeeze more IOPS out of that thing

Some time ago, one guy told us that we should fine-tune VMware vSAN a bit before beating the ujkv out of testing it. So, in this article, we check out whether using a different Storage Policy is really a key to higher VMware vSAN performance. Apart from that, we are going to see whether some of your comments really help to improve vSAN performance.

Can VMware vSAN deliver decent performance on 2 physical nodes? Poor-guys’ setup challenge

In the previous study, VMware vSAN has proven that it has balls. It, actually, has balls of steel (in John St. John’s voice )! Get ready for Round 2: Poor-guys’ setup challenge! Will VMware vSAN demonstrate the decent performance in a 2-node environment?

EMC ScaleIO – these guys won’t miss a chance to miss a chance: testing EMC ScaleIO 4-Node Cluster with Performance profile set to High performance

After the results of the first benchmark for EMC ScaleIO were published on our blog, the readers started arguing “What about enabling DM, SDC, and SDS for EMC ScaleIO you fkemheads?” Fair enough, enabling a High Performance profile on EMC ScaleIO might really boost its performance to the extent were Microsoft and StarWind (current performance leaders) become just a bunch of eqemgcvgtu constantly playing with themselves and their miserable IOPS. Well, we sure wanna give EMC ScaleIO one more chance to miss a chance 😊

Can VMware vSAN recoup on mixed NVMe-SSD underlying storage? Or, will it just mess things up [again]?

VMware vSAN performs like ujkv. Period. Well, that’s exactly what numbers told us during the previous study! And, it, probably, sucks to buy from VMware at all: we have not seen any decent vSAN alternative yet, so you, guys, need to go with a shared storage provider performing as slow as old snails hwem.

But, wait, what if vSAN mediocre performance has something to do with the underlying storage, and the solution is not a piece of ujkv after all? Yup, we read your comments. There was a guy looking for a study on just a bunch of SSD drives of smaller capacity. Well, pal, here’s the study that you’ve been asking for!

No problem, we’ll carry out VMware vSAN performance test for the THIRD HWEMKPI TIME to know the truth! You see, there’s an opinion that VMware vSAN groups smaller disks into a vsanDatastore and performs like a good software-defined storage solution should. That’s actually what we gonna try today. Let’s just hope neither we nor the solution won’t hwem anything up this time. So, lean back, grab a bag of popcorn, Doritos, or chips and enjoy the reading!

P.S. We’ve heard that guys from “mother Russia” like sunflower seeds. Well, that’s pretty weird, but if you are good with it, do a Slavic squat and grab a bag of sunflower seeds :).

This is NOT David Blaine, and that’s NOT street magic! StorMagic SvSAN 6.2 case study

Prologue

Hi, sorry for missing that long. Some time ago, we presented the eqemfight results between VMware vSAN and Microsoft S2D screwing the current performance champ for being Russian company. Having the job done, we decided to make the long-awaited trip to Europe. We ended it at some underground punk gig in Prague. Everything was just fine until cops showed up at the venue as it was a bit too noisy for guys living nearby. We “love” cops, but that’s not the main thing we are trying to tell you now.

During that gig, one of our “dream team” members said, “Guys, it seems that we forgot to test StorMagic…” Oh, ujkv, Patrick where have you been when S2D was kicking ujkv out of helpless vSAN? Where have you been when drunken bears were waving their 9” fkems? Oh, you had been working on some other stuff… What a good boy, hwem you! Ok, let’s look at this solution at least now. On the other hand, thanks to Patrick, we got a good subject for our studies – the existing vSAN alternatives. We hope that you remember how awful VMware vSAN performance is, so we guess, yes, it’s good to have some alternatives.

P.S. We played around with the format of this article a bit. We hope it gonna be more reader-friendly than any other similar ujkv on the Internet. Enjoy!
