Re: All Flash Storage

LSI 9271 is much faster on SSD's, and Samsung 845DC Pro 800GB drives are rated for over 14000TB written. The price is also not bad at all.

Re: All Flash Storage

We have good experience with Intel S3700 800GB and Samsung DC845 Pro drives. We use Supermicro enclosures/servers, as they accept off-the-shelf SSDs. LSI 9271-8i works great against their dual-expander backplanes, and the newer controllers should have Fastpath enabled by default (needed license befo...

Re: Round Robin IOPS Limit

I have always used 10 (and not 1). No special reason other than thinking it could be a little easier for the hosts and SAN?

Re: Feature requests

Sync order: Lets say we have production and dev/test on the same server. It would be nice to sync production targets first. As to the simultaneous syncs, we have 10Gig sync links, and we cannot saturate the sync link during sync with many of our targets. This is limited by storage performance (2 x S...

Feature requests

I have a couple of feature requests for HA setups: 1: sync order (what devices to sync first) 2: number of simultaneous syncs Now it looks like it is random what target is synced when (full and fast sync). When the storage is not saturating the sync links, multiple simultaneous syncs could speed up ...

Re: BUG: Incredibly high latency on HA luns in version 7509

Is this fixed now? This must be fixed NOW! We cannot run with single targets for weeks... Not good enough..

Re: BUG: Incredibly high latency on HA luns in version 7509

Yup, static will speed up rescan/boot a lot, but I have to many LUNS and paths to use static I think.. Might write a script to handle it maybe.. :)

Re: BUG: Incredibly high latency on HA luns in version 7509

Well.. I was burned again with this error. I changed the cache setting only on one node, because I would need a full sync after restart because the service will not stop properly on its own. This night my production environment went down again. I had to restart all vSphere hosts, as I could not resc...

Re: BUG: Incredibly high latency on HA luns in version 7509

Actually, after setting the cachemode to "none" on all the luns (one of the nodes), some LUNS is still reporting WB-cache in the GUI. I also see that Starwind is using 2-3 GB if RAM.
That was very strange.. I have doublechecked the cfg-file..

Re: BUG: Incredibly high latency on HA luns in version 7509

Thanks!

I hope the fix will be available soon. Most of my datastores are on SSDs, but I expect that my single large SATA/HDD-LUN will be very slow without cache.

Starwind + NVME

I'm wondering if there have been some testing on Starwind + Intel P3700-drives?
It would be interesting to see some benchmarks on an ISCSI volume!

Re: 2 hyperv nodes and 2 starwind nodes HA VM Migration prob

I can say with many years of Starwind experience, that this should work. We are using Starwind for both VMware and Hyper-V clusters (HA).
