Not 100% sure here but I believe the answer is yes and no. Yes to reading as this will round-robin bounce using MPIO iSCSI between the two nodes. No to writing as, with synchronous replication, the two nodes have to be kept identical so a write operation goes something like this: BEGIN Write to node...
I failed to get a test system set-up for HA with just one network. The wizard just doesn't seem to let it through. However, I suspect you might be able to do it by not using the cluster wizard, i.e. set-up the storage manually on both nodes and then set-up replication directly on the node. Cheers, R...
I'd like to propose the "Starwind HA storage solution" to my customers, but I cannot rely on their ability to restore the shared storage by themselves after a downtime. That is a scenario that I hadn't considered but a very valid one. In a small to medium sized business, IT could quite ea...
Ohh, you're brave! ;-) True it's just an XML file but personally I'd remove the target & device and re-create using an existing device. Chances are editing the XML will end up at the same place. Of course, you'll have to disconnect any iSCSI targets first. I believe being able to make edits like...
Yeah, we'd have the same problem with Hyper-V cluster. I mounted a test drive via iSCSI on one of the Hyper-V hosts outside of the cluster for testing.
In a two node setup, I don't see how it's possible to be very sure on which node is the master without other nodes acting as a witness. Having a 3rd ( or 5th!) node as a witness could prevent a split brain scenario.. I've been bitten by this design flaw several times over the last few years. This w...
Are these numbers from a StarWind cluster? If so what specs i.e. number of HDD, type of HDD (e.g. 1.2TB 10k 2.5 sas), RAM cache size, SSD cache, flat or LSFS? No - our current production v6 SAN is a single node (hence all my interest in HA going forward). Those tests were run on a Windows 2012 Hype...
Just to check - the test size was reduced from 4000MB to 1000MB? So we're comparing apples and not oranges ;-) Here's my results from the StarWind v6 SAN run directly on the SAN itself. Caveat: the server is currently in production so it's busy doing it's normal job - would normally run this at the ...
Actually, I'm not a big fan of IOPS either as using IOMeter, I was able to get wildly varying values on our existing SAN just by modifying the block size. It may be not scientific, but because I've used it for many devices, I like CrystalBenchMark. I think it's used by several well regarded hardware...
