StarWind Virtual SAN: Can I play with madness… RDMA?!? [ Russians kick ass again… And again! ]

Status:

Unknown. Drunken bear is playing balalaika and jerking off instead of doing rocket science. One more expedition is needed 😊

Mission:

This is effectively our second part of the study. Before, we challenged StarWind VSAN pumping data over iSCSI (TCP). And, you know what? VSAN over ancient iSCSI (TCP) performed much better in general than Microsoft Storage Spaces Direct (S2D) did over the fucking great SMB3 (RDMA). At least StarWind VSAN could handle load balancing in the right way keeping all NUMA nodes busy while S2D was playing the stretching game by putting all the dicks and their load into a single hole… NUMA node. Shame on Microsoft for trying to steal Sasha Gray’s glory! Plus, StarWind could achieve close-to-maximum performance metrics with just 3 or 4 running VMs, while Microsoft required pretty much “full house”. And, as a final cum on S2D face StarWind VSAN scaled much smoother and more predictably at the time when Storage Spaces Direct behaved like a fucking roller coaster. OK, whatever…

StarWind Virtual SAN: Can bruins get along with rocket science? [ Russians kick ass. Again. ]

Mission:

We know from TV; Russian bears can ride a bicycle in a circus and play an accordion to avoid being tazed & beaten to death. Some drunk punk told us bears are good in rocket science as well. Rocket science = high performance storage, hyperconvergence, and all that jazz. To either confirm or deny this statement we decided to give StarWind Virtual SAN scalability and performance a try. Run it, test it and compare it to a big guy Microsoft with Storage Spaces Direct (S2D) who’s our current favorite race horse, and a bunch of losers & cocksuckers (VMware vSAN, DellEMC ScaleIO & Nutanix) as well. So… Does StarWind suck or blow? Spit or swallow?

Microsoft Storage Spaces Direct (S2D) does [surprisingly!] a very good blowjob job!

Cast

Microsoft Storage Spaces Direct (S2D)

Anarchy: Well, you’ll figure out who’s sitting on the couch, and who’s holding the camera 😊.

Plot drafting

Today, we’re filming a tape with Storage Spaces Direct (S2D) running on top of the 8 NVMe datastore (2 Enterprise-grade NVMes per host). As usual, we’ll investigate how solution performs in the 4-node cluster. For test purpose, we’ll gradually increase the number of VMs running in the cluster till the overall performance stops growing. At the end, we’ll run the same tests on the single NVMe to get some reference values. Based on these reference values, we’ll judge on the overall S2D performance. How far they can jump.

VMware vSAN is great…in fucking things up! Re-investigating VMware vSAN 4-node cluster performance

Suspect:

VMware vSAN

Status:

Pretrial detention due to possible relapse

Mission:

Measure the 4-node VMware vSAN hyperconverged cluster scalability using vSAN datastore comprised out of 8 Intel SSD DC P370 drives. For this goal, we’ll keep increasing the vSAN datastore load by increasing the VMs number till we reach the saturation point where performance growth stops or till we hit the 12 VMs limit.

Nutanix takes out the anal probe…to replace it with a dildo: re-investigating Nutanix 4-node cluster performance

Suspect:

Nutanix CE (v.2018.01.31) four-node all-flash hyperconverged cluster.

We won’t say much about the subject of our today’s study since we’ve said enough in this article:

http://www.cultofanarchy.org/perfomance-test-nutanix-4-node-cluste/

Status:

Possible relapse detected. Re-investigation required.

Mission:

Measure the performance of Nutanix CE cluster built on Storage Pool out of Intel SSD DC P3700. For that goal, we’ll keep escalating the load on the Storage Pool by increasing the number of VMs till the saturation point where performance growth stops or till we have 12 VMs running in the cluster.
