Re: StarWind iSCSI SAN Version 8.0 Beta-2

And what about L2 cache?
Now, on beta3, there is no more L2 cache option... ?

Re: StarWind iSCSI SAN Version 8.0 Beta

Testing current v8 beta...
Configured an standard .iMG with 3 GB WB cache.

If you disconnect LUNs and try stopping the service, it take long and forver (refuse to stop) and you must kill task manually with Windows Task Manager.

Hope fixing in next release...

Re: Poor performance (hight latency) on Starwind vs freeNas

I've run other tests last week. I think I've resolved the mystery. The misunderstanding was due to the available cache. The HW I used was an HP server with twin "Intel Xeon" and "12 GB Ram", so FreeNAS had set its cache to 7 GB but I could only test StarWind with 512 Mb cache. Th...

Re: Poor performance (hight latency) on Starwind vs freeNas

First of all, I apologize to everyone for the automatic translation of this post! I encourage everyone to do testing on their own! I did priove on 3 different HP servers. Many of the posts on this thread are gone. But I have them all saved on my PC! I could publish them in full on my blog but it wou...

Re: Poor performance (hight latency) on Starwind vs freeNas

I run test with real data and also "random data pattern". Tomorrow I'll post you result also with IOMETER. Today I've migrated 6 VMs on ESXi from Starwind to freeNas using the same physical machine (so with no change in SAN hardware). So the test are run with real real real work. Now my VM...

Re: Poor performance (hight latency) on Starwind vs freeNas

I'm sorry but I must post another test, hoping that there is a solution for the Windows poor disk performance. Yes, Windows: because I think that it's not a Starwind limitation, but a Windows limitation (I've tried up to "Windows Server 2012" with all same results). I've tested a crazy thi...

Re: Poor performance (hight latency) on Starwind vs freeNas

Anatoly, thanks for your suggestion. I forgot to mention that: 1) I've already verified that I've no network issue (iPerf tested and at 100% 1 Gigabit) 2) I've tested StarWind with 512 Mb write-back cache (all file used for test are under 512 Mb -so they stay in cache-) 3) If I test StarWind with RA...

Poor performance (hight latency) on Starwind vs freeNas

I have to submit a question (hoping that It's a my mistake). I've notice very poor performance on StarWind but only during multiple disk access (concurrent thread) especially with ESXi. So I decided to investigate a little and make some comparison with freeNas. The result is that on sequential write...

What is the max settable "Snapshot Creation Period"?

Seems existing some problem setting high "Snapshot Creation Period" on CDP devices. I need: - max 2 snapshot - Snapshot Creation Period of 15 days. So I've defined Snapshot Creation Period (minutes) = 21600. The problem is that after 30 minutes, the first snapshot has fired. So, seems that...
