Here is two of two

Hope this helps. - Jason

Here are the starwind settings one of 2

Your're welcome... So in true HA fashion each server targets the other two nodes and itself using 127.0.0.1 for the iSCSI on the sync Anatoly set this up and if you need it I could try to do some more screen grabs but basically similar to the iSCSI but through the starwind interface the partner node...

You are crossing traffic so two separate sync channels and iscsi... hum I dunno I think I'd like to hear Starwind chime in. I would think you would not want to mix traffic or what that would cause (caveats) ? but yes you are right since you have two sync and iscsi and one goes down in that configura...

You have to have MPIO turn on. " Just trying to understand what your 10Gbe Intel iSCSI is for when you said that your have two 1Gbe ports on each server for iSCSI to the Synology." did you look at my diagram and few posts back? I suppose you could call it over kill but I wanted all of my 1...

Ok I ran the test through Starwind's CSV. Since there are not many sources for how to assign a drive letter to a CSV to test throughput and IOPS (Strategically written to help other find this post in a search engine) Here are the exact steps and the results: Syntax subst [drive1: [drive2:]Path] subs...

How would you run this test on a Starwind cluster? IE you have to have a Drive to test and the Volumes are virtual on the cluster. I hate to assign a drive letter to the volume unless there is no other way.

Well to clarify my setup (which I *think* I did in a previous post) here are my specs (Of importance to Disk speed)

Dell R710 - Raid card: PERC H700 1GB NVRAM 144GB Ram

2 (300GB SAS 10K Drives RAID 1) for OS
6 (900GB SAS 10K Drives RAID 0) for Starwind

Well still not clear to what you would like me to test. To test the CSV (which would be a true test of the Starwind system) I would need to mount the CSV as a drive and run it. Is that what you want? Here are the results running on the RAID 0 drive directly for all three nodes. Node 1 and 2 right no...

The IOPS seem to be a elusive magic number that can vary upon current loads, file size and even the software used to measure it. I struggled with that even with Starwind's great staff had problems comparing readings. VeeamOne is great, but differed from Starwind's performance graphs, which was diffe...

This was my biggest concern and trade off, however I did simulate such a failure before going into production. It took some playing to see what things happened. Funny was the OS had no idea anything happend, you just could not physically copy or move anything to the virtual drive (S: STARWIND) drive...

I don't know if this helps you, but I have almost the exact same server 3 Node setup that Anatoly from Starwind helped setup just last week and I am using direct connect. I have two Dual 10GBe Nic's (4 total per server) also two 300GB 10k sas as a RAID 0 for the OS and siz 900BGGB sas in Raid 0 for ...

oop missed the IOPS question.. A few ways but the easiest is to install the free version of VeeamOne it has a great set of real time monitoring and reporting (and a GREAT hyperv monitoring tool set) . The other way is IO meter, bu you have to assign a drive to your CSV and push data through, when it...

Well I have Dell R710's which have (4) 1Gbe nics built it, but I also have a 4 port 1GB nic (and another 2 port for another Synology SAN I use for backups) But in use, per the diagram, I have only been using two of the 1Gbe ports doing a direct link to the other two nodes for the iSCSI channel of St...

LOL I made the Software RAID mistake in another situation this year (not Clustering) but it's amazing how poorly they operate. After replacing it with a hardware raid.. poof all my problems were fixed. So good luck to you.. let hope that was the problem.
